Question : Just curious... what is a "firewall", and what importance does it play in a company's network?

Answer : A "firewall" is intended to keep the good guys in, and the bad guys out. I suspect it is named after the so-called "firewall" in your car that sits between the engine and passenger compartment. The basic function of a computer network firewall is to filter all traffic into and out of a company's network to ensure that only wanted traffic gets through. The TCP/IP protocol used on the internet uses what are called "ports". Ports are addresses of sorts for programs and exist so that when requests come in from another system it will be known what type of service is being requested. For instance when viewing this web page you are hitting port 80 on the xpertsite.com web server wihch lets it know you want a web service (at which point the request is passed to the web server process). A firewall works by blocking ports based on rules configured by the firewall or security administrator. These rules set up which side of the firewall can do what with the other side. In a typical corporate firewall you generally allow most internal traffic access to the outside (internet), and block access from external machines that attempt to access your internal machines. Without a firewall internal machines could be besieged by unwanted traffic from would-be hackers or potentially have information stolen by thieves.

Subject : Firewalls
Private : No

Question : Hey Paul, I have a question about firewalls. I have a single-server network running Netware 3.12 & I am about to build a new server that will run 4.2. The company is getting a new DSL line & I am suppose to set up the firewall. What I don't understand is, if I set up a firewall box in front of the network, will the box be a node in the network? Will I have to worry about compatability with Netware? Does it matter what version of Netware I have? Finally, will I have to get an upgrade in firewall software when I upgrade the server?

Thanks for your help.

Answer : Yes, the firewall will be part of the network in that it must be able to talk to some kind of device on your network, be it a router or hub/switch. The software on the firewalling machine is responsible for blocking the unwanted accesses. Netware will not be affected in any event as the firewall will work on the TCP/IP protocol and only on traffic bound for the outside or coming from the outside in. Internal LAN traffic will not be affected by the addition of this system. This sounds like a small or medium-sized company. Since you are adding DSL might I suggest you take a look at my favorite for this type of install - Sygate. (http://www.sybergen.com) This software will need an NT Server from you (P120/64 MB or better is sufficient). Once you have the DSL line installed and the two NICs in the server (one with the IP address provided by your ISP and the other having a valid LAN segment address and connected to a hub/router port) you simple install Sygate and it will bridge the two segments (i.e. "route them") with a full NAT implementation and act as a natural firewall (as well as being configurable to be relatively highly secure). NAT is Network Address Translation and was created by Cisco. What it allows (and in this case Sygate implements) is the ability to take non-routable addresses (like 10.x.x.x or 192.68.x.x) from an internal LAN and translate requests for external internet services through one valid IP address (the one on the external NIC on the NT Server). It has the excellent benefit of rejecting any attempts at initiating communication from outside (unless you open some ports for specific purposes, like a web server, ftp, etc) machines on the internet. It will however allow your clients full access to the 'net at large (you can throttle back if need be to stop activities like ICQ, IRC, etc if desired) so their usage is not hindered. You also have the benefit of not having to touch the client machines at all - simply set their default gateway to the IP address of the internal NIC on the NT Server and all requests will be processed by this machine. No client apps need to be adjusted as they would in a proxy environment.

All of the above can also be done identically with a Cisco (or other brand) router that support NAT - simply look for one that has at least two addressable (not hub-style) Ethernet ports and plug one into the DSL and the other into the LAN.

I have this same type of Sygate environment for a cable modem installation and it's very fast and secure. You can check your security status both now and after installation of whichever you choose by visiting this site, which will attempt to probe your address for weakness:

https://grc.com/x/ne.dll?bh0bkyd2

One thing to ensure with the Sygate install - remove the NetBIOS component entirely from the external NIC to get yourself secured. If you need help with this stage feel free to drop me a line at iqueue@home.com

Hope that helps!

Subject : Firewalls
Private : No

Question : Thanks for your VERY informative answer. Instead of this being eight follow-up questions, I just have one. In your answer, you said I would need a WIN NT box for the software. How would I get this to communicate with my Netware network? The firewall box would be connected to the network through the hub.

Answer : As long as you have TCP/IP as a protocol on the Netware boxes they will have no trouble accessing the NT machine (though I can't think of a reason why they would need to). For the purposes of your LAN users their service with the Netware boxes will be unaffected regardless of whether they use TCP/IP or IPX.

Hope that's what you needed...

Subject : network neighborhood
Private : No

Question : I have 2 computers networked by a netgear 10/100 hub, and 2 netgear 100mb cards. One machine is a win 98, and the other is a 95.
In network neighborhood, the 98 machine see's both computers. The 95 machines only see's itself. They are both configured with the same protocols.
If I go to the identification tab and change both computer name and workgroup on both machines and restart, both computers will see each other, and file and resource sharing works like it is supposed to. But when I restart/reboot the 98 machine and go into network neighborhood the 98 machine still see's both computers, and the 95 only see's itself. I can go through and change the Identifications of both computers, and they can see each other again.
Here is the trouble shooting allready done:
changed protocols
swapped nic cards
tried every port on the hub
swapped twisted pair cables
swapped to different PCI slots
reinstalled nic drivers
reinstalled operating systems
updated nic drivers
All with no different results. Ive even taken the 95 machine and hooked it up on a friends network with no problems, which makes me think that the 98 machine is where the problem is.
Ive had the network set up for around 3 months, and havent been able to figure this one out. Any help is greatly appreciated.
Thanks, Jeff

Answer : Man you've run the gamut on this one! Only problem is, I believe you've run into one of the more kludgy aspects of the Windows peer-to-peer networking scheme. Namely that of browse masters. In a Windows world every machine has the potential to be a "browse master" which is the machine that controls what everyone else sees in their Network Neighborhood. If more than one machine is set to be the broswe master (or even set to be a potential one - the default) an election can be forced to determine which will become the broswe master. By default a Windows 95/98 machine gets a vote (of low value - usually "1") while an NT Server gets a high vote (I believe a "16"). thus in a network with an NT Server the master browser will always be the NT Server unless steps are taken to make it not so. There are two things you can do to stop this behavior:

1) You can disable the ability for the 95 machine to *ever* be a browse master, thereby relegating it to the status of a browser client.

Here's how:
a) Right-click on Network Neighborhood and choose Properties.
b) Double-click File and Print Sharing for Microsoft Networks.
c) Select Browse Master and choose Disabled using the drop down list on the right. Click OK to exit this window, and OK to exit the main Network window.
d) Choose YES when asked if you would like to reboot.

2) You can ignore this and share the root of each drive (share C:\ as "C", D:\ as "D", and so on) then go to your Network Neighborhood and in the address field at the top type "\\Win95machine_name" and hit ENTER at which point you should get connected to the machine whether it appears in the NN or not. When it does go to each of it's drives or other shares and right-click each in turn and map them to a drive letter on this machine *selecting reconnect at logon* so each time this machine comes up it will connect that share to that drive letter without a visit to the Network Neighborhood. This is the best method as you will always have access to the other machines shares by letter and will soon learn which letter goes with which share (rather than have to go to NN every time and map it then). I would still recommend that you set one machine to be Browse Master (say the 98 machine) and the other to be disabled for BM ability.

thanks
tkh1@mindspring.com

Answer : I would agree with your friends. If you don not have much experience an A+ would be a good way to get your feet wet and establish some credentials. If you have enough expertise now your best bet would be to get your foot in the door as a helpdesk phone support person. Doing this for 4-6 months would enable you to then apply for a desktop support position. Once there many companies are willing to let you move into a Jr Network Administrator position and/or help train you for one. At this point you can decide if the job is for you and either continue on with obtaining the MCSE/CNE type certifications or passing it by for something else. Either way you'll have a good grounding in IT.

Subject : Novell client 32
Private : Yes

Question : I have a win95 machine using client 32 (2.2) that will not run the container script or login or profile,,, it will only run the default script on a netware 4.1 network. The run scripts check box is checked so it should run them. Any ideas why the script would not run.
Email me at nyre@kiercorp.com

Answer : This problem can come about, believe it or not, when the container itself does not have the rights to read the container login script. Give the container rights to the login script and see if that doesn't solve the problem. (you can try creating a new test user afterwards inside that container to see if it gets executed for him too, to see if it's a problem with a single user account or with the container in general).

Subject : Appletalk
Private : No

Question : Its me again, but with a new question.
Me and a friend from school are setting up a network for a company with 12 computers. 10 of them are PCs, and the other 2 are MACs. We have already run all of the cat 5 cable and sucessfully have three of the pcs talking and sharing resources. Here is our challenge. We've only worked with networking pc's. We are both brand new to MACs. We do know that apple talk is going to be the protocol to install.
1. One mac already has a nic card installed. Is it a challenge to install nic's into macs?
2. Is there a network neighborhood Icon, or something similar on the macs? And if so, is appletalk a protocol on it?
3. Are the pc's and mac's going to be able to access each other without a NT server? Or will it be one way communication?
The PC's arent really going to need to access files on the mac's, but they do want the mac's to get files from the pc's. The mac's are used for video files, but the primary concerns for the macs is to access the internet. We have a DSL line coming in, which will be uplinked from our switch.
Thanks again for all your help.
Jeff

Answer : Appletalk will be unnecessary unless you just are into pain. :-) TCP/IP is fully implemented on both machines so that should be your first choice. Installing hardware into Macs is relatively painless as they (Apple) have much more of a stranglehold on hardware makers and plug and play works much better on Macs than on PCs. If you can handle installing a NIC into a PC (as you obviously have indicated) then this will be no problem. After install there should be a TCP/IP control applet in the Apple control panels (or whatever they are called - I forget) that will let you set the IP address, gateway, netmask and so on. Just set them to be on the same segment as the PCs (unless routed) and you're off. FTP may be the best way to share resources unless you can find a client in common. For instance where I work we used to install the Netware client onto Macs who needed to share files with PCs and thereby used the Netware servers as go-betweens for the Macs and PCs.

Once your internet connection of whatever type is installed the Macs can use it in the same way the PCs do - just point their default gateway to the routing device connected to the net and you're golden.

You're welcome for the help - I'm very happy to assist...

Subject : Macs again
Private : No

Question : Just a couple of quick questions. On the network I was telling you about with the 10 pc's and 2 mac's, what is the equivilent of network neighborhood on the mac's? Will the PC's be able to see the macs on the network? And vice/versa. Im not really into the pain of apple talk configurations, so TCP/IP is the way we are going to go.
Could you explain FTP to me. I've always just assumed it was somewhat of a internet site that you bought. I understand how it transfers, but our instructor talks as if it is a network protocol. If it is, how is it configured, or added into a network.

Answer : The equivalent of the Network Neighborhood for Macs is an AppleTalk "zone" where Macs set to the same zone can freely share space and devices. As long as you use TCP/IP as your primary (in fact it's all you'll need) protocol the machines can "see" each other, although you won't get the seamless sharing you're after (ala Network Neighborhood). If I remember correctly there are several programs out that do make things more transparent; one is called Timbuktu Pro.

FTP may technically be a "protocol" but that just clouds the issue. You and I think in terms of a protocol as being a method by which a network connection is utilized. FTP in this sense is more of a transfer utility and does not need to be added (it's part of the TCP/IP suite of protocols). Here's why it's more like a utility - without the file FTP.EXE you won't be able to use said functionality - so it's kind of pointless and confusing to refer to it solely as a protocol. There is no configuration - simply type "ftp 110.23.43.42" to ftp from the current machine to the machine at address 110.23.43.42. If you have name resolution (DNS or hosts file) you can use the registered machine name instead of the IP. I'mnot sure Macs have FTP serving ability out of the box, and I know Windows 95/98 don't so a freeware FTP server is in order if you intend to do this (hmmm Timbuktu isn't sounding so bad after all ;-). You can likely find what you need at either of these URLs:

Subject : Catagory5

Question : Hi Paul,
Im trying to get a better transfer rate with my internet connection. Im going to run cat 5 from the telephone box into my house, rather than the cat 3 already installed. How can I hook up and RJ11 to the cat 5 cable so I can plug it into my modem?
Any Ideas?
Thanks, Jeff

Answer : You won't really see a benefit by using CAT 5 over CAT 3 (although the phone company doesn't even use CAT 3 - they use what's called "flat satin" which is a two-wire, no twist cable) with a phone connection. CAT 5's high number of twists is needed with the higher bandwidth demands of data transfer over Ethernet. But if you want to use it it surely won't hurt any. With the CAT 5 you will simply need to pick a pair of wires from the 4 pairs available and use them at both ends (at the phone company block outside your house, and at your RJ-11 wall plate inside). As a note the pair will occupy the middle two positions of the RJ-11 plug


(looking down on the end as it would be plugged into wall)

1 2 3 4
X X

'X's indicate where the pair of wires you chose to use should be in the RJ-11 plug.

Good luck!

Question : I am trying to decide on computer networking or computer programming for my major and I would like to find out some information about them.

Answer : Well you need to decide which you like better, or go with a general computer science and decide somewhere along the way. I do both and enjoy both. If you tend to enjoy people you'll like networking because you interact with people a lot (clients, users, etc). If you prefer working with ideas and have the mindset for it programming can be very rewarding too. My advice would be to start off your first two semesters (assuming you haven't started) and take at least 1 of each type of class - not for thr credits especially (although they'll at least act as electives no matter what major you go with) - but for the experience. you may find after one Pascal programming class it's really your thing, or maybe you'll decide the opposite is true and you really enjoy the Fundamentals of Networking and the technology around it.

Good luck, and go with what you feel!

Subject : The Macs again
Private : No

Question : Hey Paul, I have some more questions for you about Macs. Last time I wrote you I was telling you about a computer network that we had set up that had 12 pc's and 2 macs. We have the pc's up and running no problem. Its the mac's that I dont quite understand, since the major focus of school has been on pc's and microsoft software. So here is the latest. Im trying to configure the macs to talk via tcp/ip. I spent at least and hour on it and never could get it set up. I threw my hands in the air and tried appletalk and got it. The thing is, we eventually need the macs and pc's to share resources, and connect to the internet, so we need tcp/ip.
After getting into the window for setting up tcp on the macs, there is a series of information boxes for IP addresses. There is no server so Im configuring addresses manually. Im assuming that I can give both machines just about any address I want as long as the first three octates are the same for both machines. The next box is the subnet mask which I set to 255.255.255.0. The next box is a router IP, which there is no router in this network so Ive left it blank. Is that a mistake? The next box is a name server address, and there is no server on this network so that is left blank.
Does that field need the other computers IP?
Next is the search domain box. I just threw something in their, the name of the domain on this network is vpi. So I type in vpi.com. Im not sure what is supposed to go in these fields, or if anything is supposed to in them. Could you help me out on these last 3 fields: Router IP, Name server, and Domain box. Thats where I get lost. And once I do get tcp installed on both mac's do I share resources out just the same as I would share it out for apple talk?
I appreciate any help you could give me in this. Im starting to pull out hair on this setup. Thanks again,

Answer : One note - they are called "octets" - another name for a byte (8 bits)

The good thing about TCP/IP and Macs is that TCP/IP is the same no matter what system you're talking about. It's a protocol and no matter what platform is using it the same items of info need to be known. You've named most of them - now let's cover the ones you need help with:

You didn't say what you *couldn't* do with the Macs configured this way, and since your addressing sounds fines (IP address and netmask sound good as long as the same as the PCs).

***Gateway address/Router address*** - these mean the same thing. When you look at your topology from an overhead view you have waht amounts to a cable from each PC or Mac that terminates into a hub (also sometimes called a "concentrator"). All that a hub does (unless it's a different kind called a "switch" but we won't cover that here) is:

listen to all ports

send any signal received on any port out all the rest of the ports

That's it. This is what is termed an Ethernet broadcast domain. So-called broadcast since any traffic is seen by all machines on the network segment. Network Interface Cards (NICs) "listen" and when they hear a packet destined for them (determined by their MAC (Media Access Control) address - a unique number that is part of the PROM on the NIC - they pass it up the chain. If the packet isn't for them they drop it in the bitbucket (ignore it).

So now that you understand how the hub is making traffic available to your PCs and Macs (they both use Ethernet so the idea is the same) now you need to just put a couple more pieces in place for your Macs to be working like the PCs.

***Name Server*** - This is another way of saying "DNS" (Domain Name Service) and is the standard way of translating human-friendly names like "www.cnet.com" to the real IP addresses (in this case 216.200.247.130) used by TCP to send and receive data packets on the LAN and on the Internet. You *will* need this information on the Macs if you expect them to behave like normal clients. Without this information typing "www.cnet.com" and hitting enter in Netscape on that Mac will yield nothing but an error, even though TCP/IP may be working fine. So depending on how you have the PCs on the Internet, and assuming it is a network device (ISDN router, PC running Sygate, etc) of some kind you will set the Macs with the same name server information the PCs have. The numbers for the DNS servers would have come with your ISP account (usually a primary and a secondary (fallback) server are given). If you are usings these machines ONLY on a LAN and there is NO DNS server installed on the network these will necessarily have to be blank but this will make life harder for you. I'd suggest you turn a P133 or better with 64MB into an NT Server and put NT Server 4.0 on there (it comes with a DNS Server (and a WINS server, which may even be more important when it comes time to setup the sharing as WINS is to Windows sharing as DNS is to Internet addresses - namely it is by default what resolves Windows machine names into their IP addresses).

*** Domain box*** - This is pretty much superfluous in this size network as you likely do not have your own domain, and this basically just gives the machine a suffic to try to attach to anything you type if you don't fully qualify something you type. Like if you typed "www" alone and your domain box had "mydomain.com" in it, the TCP/IP stack could search for "www" AND "www.mydomain.com" before coming back with a failure message if both failed. My suggestion is if everything works with this empty ignore it (some ISPs route traffic with this so you may need to put their domain here (with whatever you want to call the machine in the HOST field).

Once you get all these things installed here are some good ways to test your functionality is to open a DOS prompt and attempt to ping the Macs by IP address.

Good luck!

FUQuestion : Hey Paul, thanks for all the help. Out of all the people I ask these questions to, your answers are the most complete.
Help me take this one step at a time, Macs are a big question mark for me.
The very first thing I would like to succeed at is getting the Mac's to talk through tcp.
Lets just say(for my benefit)that I only have 2 computers, and they are both macs. I did get them to talk through appletalk. This satisfies the company for the time being. If I could disable appletalk, and get them talking through tcp, it would be like a first baby step for me.
Since the is no DHCP, I will go in and give both machines and IP, and the 255.255.255.0 subnet mask. What else do these mac's need to share hard drives/files. Once they are configured with tcp, is the process of sharing the same as it is for appletalk. EX: clicking on a hard drive,file drop down, then sharing. Then going to the other machine, click on choosers, then apple share, and the resource, and so on. I guess what Im asking is, is sharing and accessing folders, files and drives the same process with tcp as it is with appletalk? If I could get this part working, the rest of the process is uderstandable. Let me know what you think.
Jeff

Answer : I don't see any reason to disable the Appletalk on the Macs if it is providing the service they need. You can have more than one protocol loaded. In fact it appears that unless you are running Mac OS 9 you will *have* to have Appletalk installed to shares between the Macs. Witness the following:

http://www2.mbpfx.com/gateway/gateway.html

And this:

http://www2.opendoor.com/shareway/UG/ShareWayIPHow.html

So it appears you will be stuck with Appletalk *and* TCP/IP on the Macs. Just get their TCP/IP working and leave the Appletalk as it is and see if you can get both working simultaneously (should be no problem - multiple protocols present no problem for PCs)

Subject : Internet
Private : No

Question : What is the advantage and disadvatage of promoting goods and services using website as media???

Answer : Well here are some obvious ones that spring to mind:

ADVANTAGES:

Cheap access to large consumer base - lots of "eyeballs" can see your items/services for sale at a relatively very low cost. This includes people almost anywhere in the world (broad reach).

Consumer-driven - people who want your product can find you on their own schedule, not the TVs, radios, or newspapers.

Cheaper full sales pipeline. If you implement online sales you can reduce your cost of transacting sales by a large amount (no toll-free calls even).

You can see how many people are viewing your products, and in fact can set yourself up to receive feedback from viewers of your items that allow you to finetune your items, price, and website to you customers needs.


DISADVANTAGES:

Not everyone has access to the internet. This is a big one, but is getting smaller every day. Plus the majority of those with internet access are likely to be the ones with disposable income (to afford a computer and internet account monthly fees) so the people who see your site are good candidates for your message. But this is still a limiting factor.

Some people will never find you on the internet, even if they look. Some people are not good at finding things on the internet. It's a skill that takes time to develop.

Impersonal. Though no less impersonal than a sales catalog onlines sales are less personal than even a telephone call.

Media constraints. This becomes less each day. This constraint comes about from two things IMO - lack of tools to do the media desired, and lack of bandwidth to end-users to make it feasible. Both needs are being met and even within the confines of a 56k modem much can be done, so this is actually less of a concern than it could be.


I hope that was what you were after... do not use this material verbatim in any school reports please, as that is plagiarism and dishonest. :-)

Subject : Master Browser
Private : No

Question : Could you give me a rundown on what happens with selecting a master browser. Im having a hard time getting my computers to see each other on the network. Here is what is happening. I have 2 computers networked through a hub. One is a 98 machine, the other is a 95. By default, the are both set to automatic in the master browser feild. The 98 machine will see both computers. The 95 machine only see's itself. If I disable the master browser on the 98, and restart, the 95 machine will still only see itself in network neighborhood, the 98 will see the 95 network neiborhood, and you can click on find a computer and find the 98. This is not true for the 95, it wont find the 98 when you click on find a computer. The 98 machine I keep diabled and the 95 enabled for master browser. If I change the name of the 98, and restart, they will both see each other in network neighborhood.......until I shut down the 98 and restart. Then it goes back to the same with the 95 seeing only itself, and the 98 seeing the 95 in network neighborhood. It seem the 95 machine wont hold the list of computers. It will also say the the computer name is not accessable when I do click on the 98 in network neighborhood. If I disable the master browser in the 95, and enable it on the 98 and restart, the 98 always see's both, but the 95 will only see itself. I've tried many different combinations of different settings on the master browser, and have done everything to troubleshoot these computers from the nic's, wires, drivers, renaming machines and so on. The protocols being used are: client for microsoft network(not logging into a domain),NetBeui, TCP/IP, and file and print sharing. I had them seeing each other for a long time by changing browser status, but I had to reinstall the 98 OS a week ago, and havent been able to get these machines seeing each other yet. Any ideas??????? Also, Ive install other networks with the same operating systems and never having this problem.........Does it have something to do with the fact that there is only 2 computers on this network??????? Thanks for the help.

Answer from FAQ : 52519
network neighborhood
1/10/00
Didn't we cover this topic already my friend? See my FAQ above where I answered this question for you a few weeks back. In a peer-to-peer network such as yours with no server present it may be better to simply share the root of each machine's disks (C:\ as "C", D:\ as "D", etc), go to each machine and map drive letters I: and J: to the other machine's "C" and "D" drives (setting to reconnect at logon) and be done with it. Why do you want to incur the effort and the time penalty (for the network lookup) by digging through the network neighborhood when you can already have their drive mapped just like it's a local disk?

Stop hurting yourself my friend... you aren't missing something - Windows is... :-)

Subject : here is the challenge

Question : I do understand what your saying about sharing the root of the drives, and I agree that it is not that important to see each computer in network nieghborhood. But when I share a drive on the 98, then go to the 95 and try to map a network drive, an error comes up saying the computer share name you typed in could not be found. Retype it and try again. It wont even recognize the 98 shared resource, or the name of the computer. This is what has me stumped.
By the way, sorry for asking the same question, it didnt even dawn on me about looking into the previously asked questions.
Let me know what you think.
Jeff

Answer : Now that's a horse of a different color (so to speak). From either machine you should be able to open the Network Neighborhood and in the address field type

\\othermachinename

and hit ENTER and get a list of the shares on that machine. Then right-click the share and select "Map Network Drive". A shorter alternative to this procedure is to simply right-click the Network Neighborhood icon and select Map from there but this is a better way to affirm the machine's name is accessible.

If you can not do this successfully one of two things is happening:

1) You are not using the machine's NetBIOS name - the name you should be using in the address field is the name that appears under the Identification tab when you right-click the Network Neighborhood and select Properties.

2) The machines do not share a common protocol and thus are not speaking to each other. The only one you actually need is TCP/IP since I assume these machines are also doing internet stuff. If not IPX can be used as the sole protocol for LAN-based machines. NetBeui is not required.

Paul Doherty

FUQuestion : I have verified that everything in network properties is is absolutely perfect, so many times in fact, I know every service and protocols by heart, including their properties for each of the sevices and protocols.
The only thing I can come up with is that the 95 machine may not be holding the password list for each machine. You see, the 95 only recognizes the 98 after Ive changed the 98's computer name and restarted.
So, the 95 see's the 98, but only until the 98 is shut down and restarted. Then it dissapears again until I change the 98 name again.
This is the last question I will ask on this subject. Im getting as tired of it as you are, if not more....hahaha.
Jeff

Answer : It doesn't matter whether it sees it in NN or not, if you type the other computers name (and both have the same WORKGROUP listed in their Identification tab of Network control panel) you should get a list of shares whether they machine shows up in NN or not. As I said if you can't do this check the areas I've suggested (starting with the name of the workgroup they are both in - needs to be identical).

I am completely new to Novell and Netware ver 4.0. My company uses Netware v 4.0 in DOS mode. The company purchased an HP deskjet 952 series and want to connect it to the server. I'm supposed to establish this connection. I have a B.SC in CS but not in networking.

I downloaded the printer driver from the HP site but I have no clue how to mount it on the server nor how to add the printer to the server. Please give me "assembly like" instructions on how to do this because I have zero knowledge about networking.

Thank you very much.

Mona Y.

Need More Information : Netware 4.0 in DOS mode? I'm not sure what you mean by that - can you clarify? Do you have access to any Windows 95 or 98 machines on the network? If so you can run nwadmin.exe from the server to get into Netware Administrator which is the GUI admin tool for Netware servers. From there you will need to create a printer object, a print server object and a print queue. No drivers are installed to the Netware server itself - the client machines will format the print jobs for the printer with their drivers.

Let me know about the above questions and also whether you can run nwadmin.exe from:

Server:/sys:public

Paul Doherty

Answer : Oops - fat-fingered that one -

that is

Server/sys:public

FUQuestion : Paul,

The client machines have GUI interface,windows 95/98, but the server machine is operating using DOS interface. Does this answer your question? Are you saying that I can use one of the client machines to set up the printer using GUI? If so, please clarify.

Answer : That's exactly what I am saying - you do ALL the admin of a Netware 4 and up machine from the client boxes. You will almost never need to go to the server itself with an NDS version of Netware. And even when you do need to get at the server you can do so with the RCONSOLE utility (once configured on the server - need to add RCONSOLE.NLM and RSPX.NLM (I think) to the autoexec.ncf in SYS:SYSTEM).

Question : (Scenario for Flght Dynamics) As you plan redundancy, take into account that the business accounting group performs a daily reconciliation of accounting information each night at 5:00 p.m. They also perform a weekly closing each Friday night, and a month-end closing on the last working day of each month. Each closing must be accurate to the penny and completed before the accounting system can be started the next working day. The human resources group runs a payroll on the second to last working day of each month. They are legally obligated to have a payroll out on time.

Question - What type of fault tolerance do you recommend for Flight Dynamics' business and human resources server?

Need More Information : Are you referring to backups or disk redundancy/fault tolerance?

In either case I don't see how the departments needs would change the answer (unless IT budget is a huge concern). The only issue in the question you've posed is timing of backups so they don't interfere with the client's activities.

The only answer for fault tolerance is "the best you can afford" which usually means RAID 5 arrays for disks, with DLT tape backups also.

If there is something else you were looking for here, please let me know (why I used a clarification instead of an normal answer).

Paul Doherty

FUQuestion : As far as fault tolerance, IE. disk mirroring, disk striping, and since they are using Windows NT, what would you suggest as far as redundancy and yes, tape back-up?

-junne-

Answer : As I said RAID 5 for disks is always preferable for your redunancy (and I'm talking *hardware* RAID, not software). It's faster *and* more secure than running disks alone.

As far as tape backup goes look at ArcServe for NT, and use it's scheduling ability to run backups whenever you please to avoid interfering with client activity.

RAM is more expensive.

Question : I have a Netware for Small Business 4.2 server connected to a cable modem service to provide Internet access to 8 clients. The ISP shut down our service the other day and claims our connection sent a flood of ARP broadcasts that knocked out several of their routers. I am using NAT translation and 10.255.255.255 addresses on the LAN, so I don't think the clients could have produced this activity (btw they are all Win9x). Do you have any idea what could cause my server to produce an ARP flood like this?

Answer : The clients could never produce this activity - SAP broadcasts come from IPX/SPX service-providing devices. In this case that is the server. Look for a way to disable SAP broadcasts on the outbound NIC to keep these internal inside your LAN. How the ISP expects that you are flooding them with SAP broadcasts when these are usually IPX protocol packets is beyond me, unless Small Business Server encapsulates them inside IP packets. In any event do check your configuration and turn off *all* services on the outbound NIC, not just SAPs.

2) I'll be able to make use of dsl for access to the internet
3) Be able to play games Ie: quake1,2,3 between the two

is this possible? What do i need and how do i do it? thanx for your time I really appreciate it.

Answer : Yes you can do all this with the addition of only one item - one more network card for your Windows 98 SE machine.

You will be using Win98SE's feature called ICS (Internet Connection Sharing) for this setup. The Win98 machine will have one of it's network cards going to the cable modem and the other going to:

1) The other PC directly via a cross-over cable (switch wires 1&2 and 3&6)

2) A network hub (this is the preferred method, and also sets you up for more machines later). Here is an inexpesinve hub:

http://www.us.buy.com/comp/product.asp?sku=10014722

Once the machines are configured this way you will set the Win95 machine's default gateway (under Control Panel/Network/TCPIP configuration screens) to the IP address of the internal NIC (Network Interface Card) on the 98 machine. Here's a diagram of what the layout would look like:


DSL modem
(ethernet port)
_______|
_______|
External NIC of 98 box IP 24.4.61.234, subnet mask 255.0.0.0
_____ 98 box ______
Internal NIC of 98 box IP 10.0.0.1, subnet mask 255.0.0.0
_______|
_______|
NIC of 95 machine - IP 10.0.0.2, subnet mask 255.0.0.0
______ 95 box _____


The places you see vertical bars (pipe character "|") is ethernet cabling.

I arbitrarily assigned an IP address (24.4.61.234) to your DSL modem's ethernet - this address will be gotten in a dynamic fashion so you don't really need to concern yourself with this. The addresses for the inside machines should be "non-routable" addresses and the 10.x.x.x network was set aside by the InterNIC for internal addresses and is intended for this purpose.

With this configuration both machines can hit the net at the same time and can play games both with each other on the internal LAN and together or separately on the internet!

For some nice diagrams and help with the minutia here is a good web site covering the installation of ICS on Win98SE:

Answer : >I NEED TO BE ABLE TO ACCESS THE FILES ON MY >SCO UNIX V3.2 SYSTEM FROM MY WINDOWS 98 PC.

The easiest way to send or receive file from the Unix machine is to use FTP. You likely already have it installed as a server on the UNIX machine. Just type

ftp 10.1.1.1 (UNIX machine IP)

and login with your id/password.

Another alternative is to use NFS (Network File System), a SUN innovation that is now widely utilized. NFS allows you to "export" a filesystem branch of your UNIX machine which then makes it available for others to access on the network. There are NFS apps available for both NT and 95/98. Here are some:

Question : In Windows NT how do a set the computer so the client cannot change the desktop.Thank you

Lewens@mailcity.com

Answer : I'm assuming this is a Windows NT workstation - you can use poledit.exe either in your installed copy of NT or on the NT CD (do a "find" on it for poledit*).

Another alternative is to use a 3rd-party app to do this function for you. Here are some mentions I found in a newsgroup posting:

"PC Magazine, http://www.pcmag.com , has a nifty free
program in its software library called IconLock v1.1 (dated 09-24-99) which can freeze desktop icons-- keep them from being moved or
deleted-- as well as lock all the desktop files, folders, the

Question : Hi,
i am planning to do a course on Networking. What exactly is networking?What are its potentials? Thanks for you answer and I really appreciate it.

Answer : Networking in a general sense is taking stand-alone computers and allowing them to communicate quickly and easily with each other. The typical example would be 10 desktops and a server (a networking concept in itself) at a small business. WIthout a network the 10 desktop users would have to walk their files around on floppy to share them ("sneakernet" :-) and would have to share a few printers by taking the files they need to print to one of the users who has a physically-attached printer and interrupting them to get a printout. Also all users will be responsible (or not) for making any backups needed for their data. With a network you can use a server to store individual as well as group access document areas for easy use and easy backup (since backing the server up gets both of these types of files). Printers can be shared on the network and put physically where convenient so you can print without interrupting other's work. In addition a network opens you up to group shared internet access as well, giving you the ability to perform FTP, web, and any other internet activity seamlessly.

Question : What is Windows 2000 problems ?

Need More Information : Are you asking what problems you can expect using Windows 2000? If so you can expect to not be able to play as many games, or as fast as under Windows 98. You may also have trouble for a while getting drivers for all your devices though this is improving quickly. Windows 2000 is really an upgrade to NT4 so unless you were a fan of NT4 you may want to wait for the new Windows ME (Millenium Edition) - I know it's a lame name, I didn't make it up. This is the logical progression for Windows 98 users and will be the best choice for home and power gamers.

Paul Doherty

FUQuestion : We are round 800 staff in a university, Currently we use Windows98 and Windows NT Workstation for client, Winsows NT Server for server side. My questions what problems we may face if we upgrad server or client to Windows 2000 ?

Answer : You won't have problems either way (upgrading server, workstations, or both). The only realy area of concern is if you decide to deal heavily with the new Active Directory. Even there you won't cause trouble for the clients but you could have trouble if you try linking multiple domains with it.

How do i set it up so his comp shows up in my network neigborhood. Plus how can we set this up so we can play lan games against each other? Do we need to install ipx ptotocals?

Answer : Make one of your machines the browse master and disable browse master ability on the other.

1) Click Start, point to Settings, and then click Control Panel.


2) Double-click Network, click "File and printer sharing for Microsoft Networks" on the Configuration tab, and then click Properties.


3) In the Property box, click Browse Master, click Enabled in the Value box, click OK, and then click OK.


4) Click Yes when you are prompted to restart your computer.


Once you do this you should be able to see him in the Network Neighborhood - if he doesn't immediately show up try typing

\\machinename

where "machinename" is his machine's name as shown in the network control panel, Identification tab.

I'll need to add a network card to the unix box and then I suppose cable it to the NT network's hub. Other than that I'm clueless.

I have connected Windows stations to NT servers a few times, but never a Unix box. My unix clients have always been serial devices.

Can you give me a thumbnail overview of what I need to do on each end of the connection?

Thanks a lot!

Answer : You will want to get NFS (Network File System) installed on both systems. NFS allows UNIX machines to offer up parts of their filesystems as mountable locations for other NFS-speaking machines (usually UNIX). Most UNIX systems support NFS out of the box, for the NT Server you will want to get an NFS gateway most likely. An NFS gateway will allow NT clients to access the NFS share points on the UNIX machine as if they were NT native shares with no additional software. NFS Maestro Gateway is one I remember being nice:

Question : Hi Paul,

I would like to know what your thoughts are about placing one dns in front of a firewall and another behind the firewall in a dmz zone. the firewall is a border manager server using nat.
three cards are in the border manager, one for the public side, one for the private side lan, and another for the dmz zone.

Thanks
Mark

Need More Information : Firewalls are not my specialty but I use the simpler ones occasionally. What do you see as your primary consideration here?
End :

FUQuestion : I am wondering if dns servers are usually placed out in the open-where hackers might want to see if they could have access to the file system. if the dns server becomes unavailable then the companies access to the internet via web browsers and mail coming in is unavailable. are dns servers usually placed within a protected zone or are they placed directly on the internet?

Answer : They are usually kept inside to my knowledge, since their goal is to provide service to internal clients. There is no reason to have it outside the firewall (doesn't provide any additional functionality) and it only opens it up (as you said) to attack. You can always have the DNS server send requests it can't resolve on to a higher-level DNS server on the net too.

Subject : Using ARP to learn about other networks
Private : No

Question : Cisco teach that when device A issues an ARP request for a device B which is on a LAN other than A's, router Z which knows this network address will reply.

The router Z replies with it's own MAC addresss rather than that of device B.

Why is it then that if I don't configure a default gateway in the IP stack of A, it never finds any local routers or remote device B?

Answer : I would say it's because, in the case of MS, arp is not handled well. Even in the instance where default gateway is set poorly the Windows machine will not improve it's situation. For example if the default gateway of a Windows machine points to an internal routing machine, but the packet is destined for an ISP connection, the internal routing machine is forced to forward the packet to the serial device and tells the Windows machine about the more direct route but Windows generally ignores it and continues to send to the default gateway with the end result being a functional, but inefficient, situation.


Here is also a document from Cisco on how the arp process functions:

Subject : NT 2000
Private : No

Question : Could you do a basic comparison of NT and Linux for me? Also, do you think that NT server 2000 will scale to compete against Mainframes, UNIX?
Thanks.

Answer : NT and Linux are similar in many ways:

-They both can share files and printers with clients

-They both can multitask applications

-They both can provide client-server applications to clients.


The similarities end about there. Things that are different:

-Configuration of NT occurs via the registry database which is stored in binary (but is human-readable with the right tools). Linux uses UNIX-style text files for almost all configuration settings. Some administrators prefer this method since it allows text-processing tools to be used on configurations and automated changes can easily be done. Others prefer the GUI admin tools of NT, which can make configuring things like DHCP and DNS much simpler.

-Command-line tools on Linux are better, having been "borrowed" from the UNIX ones developed over the last 25 years. UNIX shells allow full scripting support which allow for functions very near (except for lack of compilation) what you think of needing an EXE for in DOS. Windows can have some of this added on, but out of the box does not support as many command-line functions, and requires dedicated tools to perform some of these functions.

-Application support (both support and available titles) is much better in Windows. In Linux you have far fewer choices and many are unpolished at best, and downright ugly/unusable at worst.

That is a high overview of some of the key differences... hope this helped you.

Subject : Setting up internet sharing without a proxie
Private : No

Question : Hi!
I have been struggling with setting up my home network so that the internet can be shared amongst the three computers. The network is functioning, and I can share files between computers but I can not share the internet connection. I have a cable modem, so I should have more than enough bandwidth to support three computers. I know that the Gateway in the Networking control panel can be set up so that it will share an internet connection, but I dont know how to do it. I have tried a number of different proxies (Including ICS that comes with Win 98) but I have found them all lacking in one way or another. So how do I do this without a proxy?

Heres my current set up.

Computer 1)
This computer has two NICs - one for the local network (3Com 10/100), and one for the cable modem (NE2000 10).

The NIC for the Local network is set up as follows:

IP = 192.168.0.1
Subnet Mask = 255.255.255.0
WINS Configuration = Disabled.
Gateway = NULL - What to enter here?
DNS = set to the defaults provided by Comcast for the cable modem. (I dont want to divulge the details publicly)

The NIC for the Cable Modem is set up as follows:

IP = my static IP provided by Comcast (24.xx.xx.xx)
Subnet Mask = 255.255.255.0
WINS = Disabled
Gateway = the IP for Comcasts gateway (24.xx.yy.yy)
DNS - Same as above - Comcast defaults.

So I guess what I need to know is what do I need to set up the other machines as to recognize the internet connection? I have really racked my brain on this with no luck.

Thanks in advance for your help!


Answer : The subnet mask for the IP leading to the cable modem should be 255.0.0.0 but other than that your config is fine.

ICS should work fine and BTW ICS and it's ilk are not proxies, they are NAT (Network Address Translation). You will much prefer NAT to proxies as they are transparent. Proxies require reconfiguration of your net apps.

To get ICS setup go in steps. First get both NICs configured in the 98 SE machine (you've already done that). Then from that machine make you can open a DOS prompt and ping both an internal IP address (192.168.0.2 for instance) and the gateway for ComCast. No way will ICS work if you can't do this so no sense trying. If you can successfully ping both then move onto adding ICS into the mix, verify that the 98 SE can still hit both segments and then try from another machine to ping first the internal NIC on the 98 SE and then the far NIC and *then* the gateway address.

The wiring should go:

From cable modem to external NIC on 98 SE
Internally through ICS to internal NIC
From internal NIC to *normal* port on the hub (not the uplink port)
All other PCs are plugged into the same type of port as the internal NIC on the 98 SE
All PCs (besides the ICS) have their default gateways set to 192.168.0.1 with a subnet mask of 255.255.255.0 and all DNS info setup the same as on the 98 SE machine.

Paul Doherty

FUQuestion : Thanks for the speedy response! I changed the subnet mask as you suggested - still no internet at the other machines. Is it possible to get sharing without a proxy or a NAT? I tried ICS and it was too slow - even after adjusting the MTU up to cable modem settings. Thanks again!


Answer : So you got ICS working but didn't like it?

The only other way to do it without NAT (ICS, etc) is to wire the cable modem directly to the hub (the same as the PCs) but to the *uplink port* and with a crossover cable. Then you would have to pay your ISP for additional IP addresses for each of your PCs and assign these IPs to them. At that point ALL your PCs are directly connected to the internet. I *do *not* recommend this for two reasons:

1) It costs more money
2) All machines are open to attack

If you don't care about #1, #2 can be taken care of by downloading and installing this nice free firewall app on each PC:

Question : I have a pair PCs networked together with a crossover cable. The cable is CAT5. The NICs are Dlink 10/100Mbps. I'm testing network speed with netcps and am very puzzled at the results.

When I run netcps -s on machine 1 I get an average of 0.1 MBps. When I run netcps -s on machine 2 I get the 7 MBps or so you would expect. When I run netcps from machine 1 TO machine 1 (loopback) I get about 4.7 MBps.

These results are very puzzling. Can you help me out? Both machines are configured the same, although one is a K62-500 running Win98se (machine 2) and another is a Celeron 433 running Win98 (machine 1).

File & Printer Sharing _is_ enabled on both machines. I turned off all other progs before testing.

Answer : It sounds like Machine 1 has it's ethernet card set for full-duplex operation and is colliding the majority of the time with the ACKs being sent back from the other machine. Check in your Network control panel and see if your adapter has the option to switch between Full/Half duplex.


Is this behavior consistent even with a straight file copy (as opposed to netcps)?

Paul Doherty

FUQuestion : Paul,

Thanks for the timely response. This behavior is consistent with a straight file copy. (Takes FOREVER unless I copy from machine 2 to machine 1.)

It says that I have to copy a section of the Oemsetup file (NetCard) for my adapter and paste it in a section of a file. Well, I have looked on the NT Server and found the Oemsetup file, but I don't see the NetCard section. I don't know what section to copy and paste.

Answer : I think you misunderstood the web page. The file you will be adding your net card info to is not in the Windows NT Server - it's in the floppies you download from the top of that web page - click that link, downloading the associated floppy images, put those images to some floppies and *then* follow the steps using those floppies and the ones that came with your network card. When you're all done with the changes you'll be ready to install the MS network for DOS access from those install floppies.

What I want to know from an expert, is from a script (perl,ksh,sh) what is the best/easiest command I can use to check weather a DNS is setup correctly for a domain name.

This script is run every 10 minutes from cron and I would put the command in the script and if the assert doesnt check, it would send me an email/page/wake me up.

nslookup?ping?. It would be run from Solaris machines(2.6).

Thanks in advance

Need More Information : What is to you are trying to confirm? That the DNS server is still runnning? That is can resolve a certain hostname? What is it that you expect (or fear) is going to change?

Paul Doherty

FUQuestion : Im sorry Paul, let me be more specific.

We have had problems (either on our side, or the target side) where the lookup for a domain name: www.foo.com will not resolve to a valid ip address.

So what I want to do every 10 minutes is validate that a domain name www.foo.com, resolves to a valid ip address.

I know nslookup does this kind of lookup. But the output that comes back from nslookup is complicated to parse inside of my shell script. So I was wondering if there was a different command I could run instead to accomplish this.

Answer : Well a ping output to a text file (/tmp/pingout) and then parsed for the string "unknown host" should let you know whether the name was resolved or not. You will likely need to include a cache-flushing mechanism to ensure the name/address doesn't get stored and result in a successful ping when the site is actually down.

Here are some ping results that illustrate what I mentioned above:

A good address...
# ping www.foo.com
foo.com is alive

A bad one...
# ping www.fooonyou.com
ping: unknown host www.fooonyou.com

Answer : After the first gets added just enter the Netowkr control panel and, from the adapter tab, click Add to add the next one. If both NICs are of the same type you will have to supply the MAC address from each NIC to uniquely identify it. You can get the MAC address by running

ipconfig /all

from a DOS prompt. The MAC address will be the long hexadecimal number like this:

Subject : client server network
Private : No

Question : I am trying to establish a client-server network using WindowsNT Workstation 4.0 (service pack 5) on a Compaq Presario 5441 (AMD K-6 475MHz, 196 MB Ram) and Windows NT Server 4.0( service Pack 5) on a DELL XPS T500 ( Intel Pentium III 500MHZ, 128 MB RAM) . I established an account for the client ( Compaq ) using server manager tool on the server (DELL). In addition, I made the client join the domain by using the network applet. Both client and server are on the same domain (domain 1). My problem arises when I try to log onto the domain from the client, using an administrator account that exists on both the client and server. I receive an error message that states the system cannot log you on to this domain, because the systems computer account in its primary domain is missing or the passwords on that account is incorrect. Also, when I double click on the client computer in server manager, I receive the error trust relationship between workstation & primary domain failed. I have created the computer account on the server and made the client join the domain several times, but I still have the same problem. Does anyone have any suggestions? Thank You.

Answer : Remove the computer acct from the Server Manager, then with the DOMAIN administrator account password go to the workstation and join it to the domain by putting in the domain name in all applicable areas (both in the "workgroup" field and also in the security method (select user controlled share access and put the domain name as the controlling authority). There is no need to manually add an entry to server manager if you know the administrator password for the domain.

Paul Doherty

FUQuestion : I couldn't agree with you more. I have this vague homework assignment, and I don't want to assume anything but, let's say that the only forms of communication in operation currently are telephones and meetings. I'm not looking for specific costs, but maybe some high-tech options (palm pilots, wireless phones etc) to present to my "senior-level management crew". At this point, I imagine the company is in complete chaos with archaic means of communication or none at all.

Thanks for your help.

Answer : If all employees can be assumed to have PCs then the following come immediately to mind:

1) LAN-based email system

2) Internet-based email

3) PDAs (Palm Pilots, perhaps with wireless messaging - Palm VII)

I hope this helps...

Subject : Win2k and win98 networking.
Private : Yes

Question : Hello.
I have a desktop running Windows 2000 Professional edition and a laptop running Windows 98 OEM release. I am trying to connect the two computers together for internet access. My ISP is @home (cable access).
What I have done is buy a NIC for my desktop and another one for the laptop so we can share internet access, with the desktop being the host.
Now this worked when I was running Windows 98 on my desktop. All I had to do was set up the desktop as a proxy with WinProxy 2.0. But this was easily done under the previous features, since I knew how to set up the TCP/IP properties and the two computers could see each other even before I set up the proxy. Now I'd like to do the same thing for the new O.S., but since I'm fairly new to it, I don't know how to make it work. I've been doing some research and read some things about NAT, but am not sure how to set it up. Could you please point me to a site, or send me detailed instructions on how to set this up? (I have already tried timhiggins.com but those instructions weren't thorough enough for my limited networking capabilities.)
Thank you in advance.

Answer : ICS exists on both Win98SE and Win2K. Install a second NIC (the first going to the cable modem) into the desktop computer and turn on ICS. Here's the appropriate page from the URL you provided:

http://www.timhiggins.com/ppd/ics.htm

Doing it this way is far prefereable to a proxy since proxies stop most apps and require others to be reconfigured. NAT (what ICS does) is transparent. Just set the notebooks' default gateway to the address of the second NIC you added to the desktop (use 10.1.1.1 for the second NIC on the Win2K box and 10.1.1.2 on the NIX in the laptop - subnet mask of 255.255.255.0 (fake class C)).

Question : I am having a problem with one of my computers on the company network. There seems to be a comunication error between the computer and printer, the printer is a HP 850C. When I try to delete the printer from the control panel it tells me that the default printer (being the 850C) has been deleted and it is now making the HP 850C the default printer. This all seems very strange! I am using HP Jetadmin to create jetdirect ports but any time I try to delete the port so as I can re-create it, it wont let me do it. It usually trows up Dr. Watson and throws me out. I have configured the TCP/IP address correctly but am running out of ideas.
Any suggestions.

Need More Information : Is the printer connected directly to the PC? Is so, why are you using JetAdmin?

Paul Doherty

FUQuestion : Sorry paul,
the printer is connected on a network via network cables and connects into a jetdirect box, hence the need for the port. The computer is a NT 4.0 workstation.

Answer : Why not just create *another* port with JetAdmin the way you want it and ignore the other one? Then create another version of the printer connection (object) and set it to be the default. Then maybe you will be able to delete the old printer and port.

Question : What steps would I take to network my IBM(s) clone Pentium w/ win98, to my MAC(s) w/ OS/8.

Answer : Very simple - just get an ethernet hub (4 or 8-port will do nicely - depends on growth) and plug them all into it. Then give them IP addresses from the same range (giving each machine a unique number). My favorite for internal LANs is:

10.1.1.1
10.1.1.2
...
10.1.1.254

Any addresses in this range are good for internal LANs because they were pre-allocated by the InterNIC to be non-routable addresses.

Use a subnet mask of 255.0.0.0 and you have your LAN.

I am running Windows NT Server 4.0 with IIS4. Right after I installed a 3Comm NIC the computer froze a little then rebooted. When it came to the logon prompt it froze a little again and rebooted again. This cycle of automatic rebooting continues until I turn off the computer.

I was wondering if there is something I can do to return the computer to an operational condition.

Otherwise is there a way to uninstall Windows NT entirely for maybe Windows 98.

Any help you could give me would be greatly appreciated.

Thank you very much.

Sincerely,
Karim


Answer : Well it seems you have a pretty good idea of the culprit here - the NIC or it's drivers (or the installation method). Try removing the NIC from the machine and booting. If it makes it in you can remove it from the NT configuration (Network control panel) and then try adding it again (try another slot). make sure you are using the latest drivers for your OS rev from the manufacturer's site. Another place to find them is here:

http://winfiles.cnet.com/drivers/network.html

You can always remove the NT installation by the following:

fdisk and remove the partitions - if any are NTFS use delpart to remove them - http://ftpsearch.lycos.com/cgi-bin/search?form=lycosnet&query=delpart.exe&filetype=All+files

After removing the partitions you can recreate a new one(s) with fdisk. Also perform an

fdisk /mbr

to remove the boot block from NT. You may need to put the fdisk and format commands on a floppy and boot from the floppy.

Subject : Windows 2000 or Novell

Question : Our company has been working on a peer to peer Windows 9X environment. We have a feeling that alot of the problems we have been having are caused by working in this peer to peer environment and for that reason and others (such as security) have decided to switch to a dedicated server environment. The big question is Novell or Windows 2000? I have heard extensive and passionate opinions on both ends and was wondering your feelings on the matter and why.

Thank you so much

Answer : Well I am certified in both Microsoft and Novell but I must say that I tend to side with Netware for larger installations and Windows NT for smaller ones. Netware is a far better directory service-enabled OS. Win2k just being out and being a 1.0 release of a directory service for MS can not compare to Netware's 7-9 years in the market as a directory service.

So if you have only the one site and have less than 25 users I'd say go with NT; if you are larger go with Netware.

Paul Doherty

FUQuestion : Thank you so much for your quick repsonse. I wanted to clarify why you would choose NT for less than 25 people. Is is just because NT is easier to administrate in a smaller group or is is just a better product in a smaller environment ? Thank you

Answer : NT runs quite well (and fast) with a small load, and as you mentioned, is easier to administrate (and doesn't require a separate client - technically neither does Netware but if you want full functionality i'd suggest you use Novell's client).

Answer : I have never seen anyone add a printer this way but I did find some information about it (relates to NT4 but Win2K likely has the same utility):

Question:
How do I add a network printer to Windows 95 and/or NT 4.0?
Answer:
Are these Network printers or are they local printers?
If they are network printers, I was able to do this by querying the NT server for all Printer Devices, creating a menu with these printers and then using Microsoft's CON2PRT.EXE utility (from the NT Reskit) to install the specific printers. With this tool you can install a network printer from within a single command line. You can also use this tool to set the default network printer.

This utility is included in the Microsoft Zero Admin Tool kit.

Here is an explanation of exactly how to use the CON2PRT.EXE utility:

I need to establish long distance connections, mostly out of state and possibly a few international connections. However all the information Im finding only speaks of using dialup.

What do I need to do to connect with the DSL?

Answer : Well since the DSL connects you to the internet and does not allow you to make a point-to-point connection like a modem does you will need to establish a VPN (Virtual Private Network) connection with the other sites if you want access to their LAN. If all you want is to securely remotely admin the servers at the other site you can use pCAnyWhere or one I've used, RemotelyAnywhere (http://www.remotelyanywhere.com). RA uses a nice java client windows inside your browser which allow you to admin their (and your) servers from any machine in the world that has web access - very sweet. It will work great with your DSL line.

the domain set to the logged into from

under the access control tab select user-level access control so the PDC can control access to all network resources (including the 95 machine's resources)

If these steps don't work (they need to be set this way anyway) try opening a DOS prompt and pinging the server's IP address. You may have a network issue - be sure your network works before trying to login to the domain again.

FUQuestion : Thanks for your recent answer. By the way, What is the diffrent between "Share-level access control" and "User-level access control" ? Can u explain it in detail ?

2)On one of the workstation PC,I have not share the the hard disk drive but it still be able to access from the network on the other workstation PC. The access is Full Access. Pls help me on this matter. I can only be solving this by reinstall the software.

Answer : The difference between user-level and share-level access is important to know, especially since you have an NT Server involved.

Share-level means access by other machines on the network to your shared resources (like directories) is controlled by a password assigned to each share individually. Not only is this cumbersome but it's not very secure as anyone can hop on your desktop machine without a password and start sharing things. A user's permission to access a resource is done on the local workstation which compares the password given to the one assigned to the share. Another downside to share-level is that your access choices are not very granular. You have full access or read-only in addition to none.

User-level access means that resources are accessed by who you are, rather than what password you provide. In the absence of a PDC (Windows NT Server in Primary Domain Controller mode) this doesn't make much sense. With a PDC in place this is your best bet for ease of use and security. Once set to user-level security your PC will not give up access to any resource unless that access is first authenticated by the PDC controlling the domain. This makes it a lot tougher for anyone over a network to get at your local machine's files. You also get more granular control over the type of access you give with user level, being able to set specific rights like delete and create on specific users or groups per share.

The answer to question #2 (if I understood it) is to set the sharing on that machine to user-level. And ensure it is logging properly into the PDC.

Pls reply ASAP! Thx a lot!!

Answer : To be able to have your own domain name you will have to have DNS Server running on the NT Server (you may already have it). See your administrator about the steps to adding a new domain. An alternative is to have people hit your web page by it's IP address since you seem only interested in internal machines getting to the web pages you're making. I'm not sure why you would need two network adapters for your web server - isn't the proxy providing you (restricted) access to the net at large? Why would you need to bypass it? If you intend to do anything on the net at large with your web server the domain name will need to be registered with the real DNS servers on the net - this takes some time and money - do a search for "domain name regostration" in any search engine for companies that will help with the process.

Subject : Network Display Settings
Private : No

Question : Hi, I got a major problem and I was wondering if you can help a poor guy out like me. On my school networked computer I played a game and the game changed the screen size. It looks really wierd and I have to use the mouse to see the other parts of the screen. I went to control panel but there was no display option. Do you know if there are any others way to change it back to normal? Is there some other way to configure it, how bout a program? And another thing, the administrator disabled the right-click option but i can enter into all the other drives. Thanks.

Answer : Can you not get the administrator to fix it? Since they were the one to lock down the machine they should be the one you ask to repair it since you really have been limited in your ability to fix it yourself. Barring that you could try booting in Safe mode (press F8 or hold CTRL during boot) and see if you can set display options there. If not then you may need a copy of poledit.exe (Policy Editor) which is likely what the admin used to lock you out. Inside it you will see various options for the local computer and can turn back on the items he disabled.

i have this problem about the security of my win98 os...u know our network administrator can access any computer on our lan eventhough he was not given a permission....now is there any software or solution that he cant anymore access my comp from his place...
another thing how can i prevent him from tracing my passwords...
i dont have privacy anymore...please help me...
thnx

Answer : Don't log into his domain controller and he can;t gain access to your PC. If you do login to his domain controller just be sure you don't have anything shared and he shouldn't be able to see anything on your PC. What makes you believe he can get to anything or see your passwords?

it cant be because i browse internet through our lan
i didnt share anything to him
even at remote admin i remove domain admin..
but he still able to get mt password and browse my comp...
another thing my ip address stays the same unless i dont login for one week...we use private ip address here...like for example this one...he knows that im connected to u...how can i avoid this?
Rating : 4

Answer : He can't get your passwords across the network or anywhere else unless he is using some cracking tools. Even the person with the administrator account and password for the domain cannot read anyone's password. They can *change* anyone's password but cannot read it's value.

Do not remove your networking components - you need them to access the file server and the internet. Again - what makes you believe he is able to get your password and browse your computer? Open your NetWatcher to see what shares you have open on your machine (Start/Programs/Accessories/System Tools/NetWatcher). Make sure you have no administrative shares (end in a "$" symbol - like "C$").

Why do you care about your IP address being the same? Even when it changes you could still be found by your network card's MAC address (Media Access Control). It is unique and non-changing. If you think it will help you can change your address as often as you like by running WINIPCFG /ALL, and hitting RELEASE ALL, and then RENEW ALL.

The only way to avoid any possibility of detection on the local LAN getting onto the internet is to:

1) Encrypt everything you do (not feasible)
2) Connect with an alternate device like a modem.

i was able to conclude that he was browsing my comp because i was able to see him using my netwatcher...
he was sniffing at my drive c..
about u said on sharing ...i share nothing on my pc except printers....
is there anything i can do to prevent him from cracking my comp...

on the other hand about ip addreess...ur right
that my stlye of changning ip address but he still can get me...is there anyway i can bluff him

Answer : Ah that's a different story!

If he is controlling your PC remotely he is likely using the remote control component of SMS. If you want stop him kill the SMS tasks in your CTRL-ALT-DEL dialog box. Keep explorer, systray and any others you *know* are your apps running and kill the rest.

I have a license number, but I just dont know how to create the .nlm file that it asks for during the installation.

Thanks in advance,

Answer : It isn't an NLM - it's a file called "license" on the floppy. I don;t know of any free ones except maybe the ones they give away that are two-connection versions - you usually need to attend one of their seminars to get those. Try calling Novell - they may be giving them out now - they have done so before - anyone who called in used to get Netware 4 two or three-user versions for free.

What is the different between these two type of security?And what is the

Thank you!!!!

From :

William

Need More Information : Please clarify your question - unless I am misreading you are asking about two different types of security. Firewalls block access to or from networks by allowing/disallowing specific ports to pass. NT security is a user/resource access security method that doesn't have anything to do with networks communicating, just with clients and other servers accessing, or being denied access, to the server's resources.

That may have answered your question - let me know.

Why we want to using these type of network security?


From:

William

Answer : Packet filtering is just that - firewalls can stop packets from a certain address *or* of a certain type based on the rules configured by the admin. Address hiding would be like NAT (Network Address Translation) where the IP addresses of a network are shielded from outside networks by translating at the NAT device.

We use these things to:

1) keep our data away from those who should not see it

2) Keep people from messing with our machines without autorization

3) Allow internal networks to safely browse the net

Subject : Network transfer speed

Question : Paul,

Good afternoon. I have two PC's in my house that are networked together with LinkSys 100tx network cards, a LinkSys 100 base HUB, and I have CAT 5 network cables (the two machines are only 15 feet apart). When transfering files I've noticed that I'm only getting around 730k/sec for my transfer rates. I tested the transfer rate using Windows 98's, my OS, System Monitor programs with the Network Monitor installed from the Win98 SE disk. Is this correct or could there be a setup problem that is limiting my speed?

Thanks,

Greg.

Answer : That's not bad speed but I understand why you would expect more given 100Mb. Check the properties on each NIC in the network control panel and see if you have full-duplex enabled. It should *not* be enabled unless your hub is actually a switch (and you used the wrong name). Set both to half-duplex and try some speed tests again.

FUQuestion : Paul,

I do have a hub, not a switch, and I had actually tried changing the connection type on each NIC to TP_100_X_Full_Duplex, the original setting was AutoDetect. Thanks to your answer I see why my connection speed then slowed WAY down, at least I'm assuming, it was because I have a hub not a switch. I then set both NICs to TP_100_X (I'd assume this is the half duplex setting) and it took almost exactly the same time to transfer files as it did with the AutoDetect setting. I did time the transfers too and I use a large, 225Mb, sized folder to test the transfer. :) Any other suggestions?


Thanks,

Greg

Answer : If you know that TP_100_X is the half-duplex setting then that is all I can suggest for speed. Ensure they are both half-duplex. With a simple hub and only two PCs you should be getting the best speed you can without any tweaking.

Question : what is the the best way to connect 12 computers togather and what is the best topology we have to use ?

note: 12 computers for busniess.

Answer : The best way is probably get your self a 16-port Ethernet hub or switch and wire them all up to it with CAT-5 cabling. You can achieve 100Mb/sec speeds with the latest models and can grow with additional hubs/switches as needed. It's inexpensive and relatively long-distance (100M - 300 feet per connection from the hub). The topology of any hub device is physically a star, but logically a bus.

Question :

Dear Sir,

I'm Lance from the Philippines.

I'm just wandering where the Unix system puts its password file?

How can I protect this password file or is there a possibility that someone can download this and crack the encrypted password file?


Answer : Unix security usually uses a combination of the two files:

/etc/passwd
/etc/shadow

The passwd file is readable by the general user, while the shadow contains and encrypted form of the password and is readable only by root or programs set to run as root. The login process has the ability to read the shadow file and will compare the password you give to the one stored in the shadow file to ensure they match. It is unlikely that someone can directly steal the shadow file. more likely is that they will gain root access somehow and steal it that way (since root can read/copy the file).

Question : Hi.

I have two computer at home and I will like to communicating these two computer each other.
Would you tell me the procedural for set up the network?
Is there any web site show this procedural?

Thank you.

Answer : Obtain an ethernet card for each PC and one Ethernet hub (or switch). Install one card into each PC and assign each of them the following info:

PC #1
IP address - 192.168.0.1
Subnet Mask - 255.255.255.0
Default Gateway (leave blank)
DNS (leave blank)

PC #2
IP address - 192.168.0.2
Subnet Mask - 255.255.255.0
Default Gateway (leave blank)
DNS (leave blank)

This will get the PCs talking. Now make sure each is in the same "workgroup" by entering the Network control panel, under the Identification tab and put a name there (make it the same on each). Then turn on file and print sharing from the Configuration tab, button at the bottom. Finally make one machine the browse master and disable the other as follows:

On PC #1 open Network control panel and double-click on "File and print sharing for Microsoft Networks" and in the choices that pop up select "Browse Master" at the left and choose "diabled" at the right. On the other machine go to the same screen but choose "enabled". Reboot both machines and then open the Network Neighborhood from the desktop and see if you can see the other computers name. If you can't don;t despair (it takes several minutes sometimes for the browse mastering to sync up) type in the address field of Network Neighborhood:

\\machinename

and hit ENTER to see the contents of that machine. Since you haven't shared anything yet you probably won't see anything but if it opens at all your network is working. Now share some things - open My Computer and your C: drive. Find a directory in there you'd like to make available and right-click it and select "Share" to set it up for access by the other machine. You can do the same with printers so you can both print to one printer that is connected to only one of the machines.

Have fun!

Subject : Connection reset by peer problem
Private : No

Question : Good afternoon everyone, and thanks for taking time to peruse my question.

This is a troubling problem I have been having since I switched to cable modem many moons ago. Now, on with the torture.

Brief Description: My computer gets packet death about 10-15 times a day (see below for interval).

Where am I seeing this occur?: I run mIRC (IRC Client), and it receives winsock error 10054 (connection reset by peer). When the packet death occurs other programs become afflicted. ICQ dies, I cannot load any web pages, etc.

Info:
* The interval is usually 2-5 hours, but sometimes as frequent as 5-15 minutes.
* I cannot traceroute (even with non-resolving host names) during this period of downtime (usually lasting 1-2 minutes).
* I have gone 3 days without an error before. This morning, I had 6 in the span of 2 hours.
* My cable modem's "Online" light remains on, although I cannot access anything on the Internet.

Things I have ruled out:
* Cabling
* The cable modem itself
* 80% Sure it is not the fault of COX Internet (Provider)

Things I am unsure of or have not ruled out:
* Signal strength
* Something to do with IP Leasing
* Major Attacks (I have run a firewall with no sign of attack, but have not packetsniffed my UDP)
* Environmental factors (what would these be?)

So, in conclusion, does anyone know what could be causing my computer's Internet connection to die periodically (frequently more like it) based on the criteria above?

I appreciate your help greatly in solving this frustrating problem.

Thanks,
Blair

Answer : The Windows IP stack may be at fault. To determine if this is the case try obtaining another PC you can hook to the cable modem for a day or two. If this second machine does not experience the same problem then the IP stack in Windows is likely to be at fault and you may want to reinstall Windows. If the machine does have the same problems then you can safely point the finger at the cable modem or further upstream at the ISP.

Answer : Yes but if you're using the same ISP account they both can't be on at once obviously. Just configure both machine's dial-up networking for the same account and when you want to use it across Sygate the desktop will be dialed in (and both machines can access it) - and when you want the notebook to have it you can dial in with it.

I think I have all the equipments.
Or let me know the web site that explain making network at home.

Thank You.

Answer : The equipment:

2 Ethernet cards
An Ethernet hub or switch
Cabling (preferably CAT5)

The steps:
install each NIC (Network Interface Card - the Ethernet cards) into a computer.
Connect a cable from each PC's NIC to a port on the hub.
Assign IP addresses manually to each PC (double click on the TCP/IP protocol entry in the Network control panel to access these parameters):

PC #1

IP address - 192.168.1.1
Subnet Mask - 255.255.255.0
Default Gateway - leave blank
DNS Servers - leave blank

PC #2

IP address - 192.168.1.2
Subnet Mask - 255.255.255.0
Default Gateway - leave blank
DNS Servers - leave blank

Make one machine the master browser by entering the Network control panel, adding "File and Printer sharing" if it's not already in the list by clicking the button at the bottom, and when it's in the list double-click it and select "browse Master" and set to "enabled" on one machine and "disabled" on the other. Also ensure that both PCs are in the same workgroup (Identification tab in Network control panel).

test connection by opeining Network Neighborhood and typing:

\\machine1_name

from PC #2 (or vice-versa). If successful you can now right-click on drives, directories or printers and select "Sharing" to let the other machine have access to that resource.

Subject : TTL value
Private : No

Question : What does the number shown in the TTL value represent ?

Answer : TTL is the "Time To Live" value for a TCP/IP packet, and refers to how many hops a packet can pass before it is considered a "dead" packet and is dropped.

As a packet is transferred across an IP network every device that connects dissimilar-addressed networks like a router will decrement (reduce by 1) this TTL number. If the packet travels long enough, or the initial TTL value is set low to begin with, the packet will be dropped. The TTL value helps to avoid a few pitfalls of the TCP/IP protocol. Primarily it helps avoid long travels in the event of a network disruption due to an outage or reconfiguration. It also prevents "packet loops" where a routing error may send a packet on a roundabout path that keeps repeating. Without the TTL value being finite and being decremented each time it passes a network device the packet could eat up needed bandwidth (along with any others that may be doing the same) making solving the problem more difficult due to the congestion.

Subject : Win2000 and Win98 Interconnectivity

Question : "HI!

I installed Windows 2000 Professional Edition on a Hewlett Packard Netserver. I'm trying to connect several other workstations (all running on Windows 98) to that
particular machine. I'm trying to put up a peer-to-peer LAN here. With the machine running Win2000 as the server and the ones running Win98 as the workstations.
All the workstations can see the server and the server can see all the workstations in the Network Neighborhood. It's just that I can't navigate inside the server when
I'm using the workstations. I seem to be having problems with the Win2000 security features, or something is wrong with the way my Win98 client is configured. Do
I have to change drive mappings in the Server or the Workstations? I tried to create users and cleared some directories in the Server as shareable just so I can
access them trough the workstation. But it simply won't work. What could have gone wrong? What do I need to change in the Server's (as well as the workstations)
configuration so I can make it work?

BTW, I intend to create a shareable directory inside the server which will contain all the database files of a shared DELPHI application.

Thank you so much. I really wish you can help me with this.

Answer : Well part of the problem is that you cannot "log into" Win2K Pro in this way - Win2K Pro is the logical descendent to Windows NT 4 Workstation, not Server. This means that Pro is not intended to authenticate users and such. What you need to do is set the 98 machines to "Share-level" access (Network control panel/Access Control tab) and also set the workgroup name to be the same on all 98 machines as well as the Win2K machine (and be sure it is set to be a member of a workgroup, not a domain). Once these are done share the directories or drives on the Win2K machine that you want to access from the 98 boxes. Make sure File & Print sharing is installed on the 98 machines so they can share items too if needed. Also disable all the 98 machines master browsing ability - Network control panel, double-click File & Print sharing for Microsoft, select Browse Master and select disabled. This will ensure the WIn2K box performs these services.


Reboot all the machines and test access by opening a Network Neighborhood on a 98 machine. If you don't immediately see the other boxes don't sweat too much as it can sometimes take a while for the browse info to get updated. In any event type in the address field of NN:

\\Win2K_Name

(where Win2K_Name" is the name assigned to the Windows 2K machine)

and see if you can get a list of it's shares. If you do then you are successful. You can then map one or more of the shares to one of your drive letters and set it to reconnect each startup.

1) Install Direct Cable Connection (Start/Settings/Control Panel/Add-Remove Software/Windows Setup tab/Communications/Details/Direct Cable Connection). This will involve a null-modem serial cable or parallel cable(?).

2) Download this utility

http://members.home.net/iqueue/xport.exe

and build two boot floppies - copy this file to it and run it on each machine with the machines connected by a bull-modem serial cable. Only thing to be aware of here is that long filenames may lose their... long-ness. :-)

Subject : Autometic IP
Private : No

Question : I have one notebook with Win98.
I need use it in 2 subnet. Each subnet has its DHCP server. I set it get autometic IP in TCP/IP poperties. Now in subnet A it can get a success IP. But when I use it in subnet B the next day, after it bootup, I found it still get the old IP from Subnet A. I use command "ipconfig /release_all". But it doesn't work. Now I need manually input IP address when I change subnet. How I can use autometic IP?

Thank you for your help.

Answer : The DHCP setting should obtain a new address on each subnet automatically. if it isn't there may be something different about the DHCP servers. Ask your administrator to verify the DHCP functionality. Also ensure that you do not have any hard-coded information about Default Gateway in the TCP/IP settings on your machine. If you have hard-coded that setting it will work on one subnet but not the other.

In any event under Windows 98 you would want to do a:

ipconfig /release_all

followed by a:

ipconfig /renew_all

Subject : about routers
Private : Yes

Question : First of all I don't know any thing about routers. Tell me about routers. How do I configure routers .What is the main use of routers?

Answer : Routers perform one simple task - they connect network segments together. Those network segments need connecting devices because they are either:

1) Different segments of the same protocol (IP address networks)

2) Different topologies (frame relay or ISDN to Ethernet for example)

Since these networks cannot normally interact directly with each other a router is used. Simpler devices can sometimes be used for connecting dissimilar topologies, but more often than not a router is used for the additional benefits it provides. A router by itself has a simple function - route traffic from one interface (say coming in an ISDN port on the router) to another interface (say the Ethernet port on the router). But multiple routers on multiple networks also perform another function - ensuring that packets get where they're destined, and that they do so in an efficient manner. Routing protocols like RIP and EIGRP allow routers to communicate at different levels of sophistication to make each router aware of the distance (sometimes called "cost") and path to be taken between points on the internetwork. Routers can also perform security functions, using access lists to keep out unwanted IP address ranges for example. They can also perform other duties like NAT (Network Address Translation) which allows normally non-routable addressed LANs to be connected to the internet without modifying the clients.

If you want to learn to configure routers you will need to take some classes - Cisco is the leading provider of these devices and offers courses starting with Introduction to Cisco Router Configuration.

Answer : You're atlking about three different jobs in two different categories.

Jobs are:

Systems Administration
Cisco Router Administration

Your choice of these two will be governed by what you enjoy doing. You had best talk to people doing both before committing to either path to be sure it's one you'll like.

Your other choice was within the Systems Administration category, between NT and Solaris. Again let several factors be your guide:

1) Which do you know more about?
2) Which do you enjoy more?
3) Which does the market desire more (more jobs, better pay)?

Good luck in your endeavors!

Subject : DCC installation
Private : No

Question : I have recently asked about hooking up two computers at home together and I got numerous answers, one of those being Direct Cable Connection. I though that this would be the best option because I didn't really want to install two ethernet cards and I didn't really need my connection between the two to be all that fast (I had heard that the DCC goes at about 100kps while the 10-BaseT goes at 10mbs), but the person who told me about DCC said that he didn't really use it and didn't really know how to use it. Can you help me out by telling me how I would go about installing the DCC and about how much money it would cost me? As a side note, though I'm not sure if this is important or not: one computer is a PII 266 w/ 64 MB of RAM and Windows 98 first edition and the second is a PIII 733 w/ 128 MB of RAM and Windows 98 second edition from Dell. Any help would be greatly appreciated! Thanx!

Answer : To install it just open your Add/Remove Programs control panel, open the Windows Setup tab, click on Communications and check the box for Direct Cable Connection. once installed you can access the program under:

Start/Programs/Accessories/Communications/Direct Cable Connection

You will need to each "share" your drives and/or directories you want to use across the cable. Once you've installed DCC try right-clicking on a drive (say C:) inside the My Computer window - it should have an option on the menu called "Sharing" - if it doesn't open the Network control panel, click the File and Print Sharing button at the bottom and check one or both of the boxes.

For the best speed use a parallel cable instead of the serial cable (a null-modem serial cable needs to be used if you choose serial). You can get a high-speed parallel cable (make sure to tell them you want to use it for connecting two Windows PCs) from:

Question : I was wondering if you could use more than one lan card in a machine to use your machine as a hub? If you could would they both have to be of the same brand?

Answer : Yes you can, and no they don;t need to be the same brand - in fact it's easier if they aren't since you then don't need to pay attention to MAC addresses.

As far as it acting as a "hub" that's not exactly the case. A machine with two NICs can route given the proper OS and software. For example with 98SE you can use two NICs and route a cable modem, DSL, or regular modem for a network of other machines.

Private : Yes

Question : Hi, I'm new to this and am having a few problems. I set up a 10BASE-T peer-to-peer (just two computers) using 3Com's Office Connect kit. All the hardware is working fine. I can print on both computers, and access all the drives on both computers. When I place an audio CD in my computers CD-ROM (Drifter_2) and try to access it in my other computer (Drifter) I can see all the tracks on the CD. However, when I double click one of the tracks from Drifter I get the following message: "The disc that you are trying to play is not inserted in the CD-ROM drive. Please insert the correct disc and try again." My Drifter computers (running Win 95, ver 4.00.950) CD-ROM letter is E:. My Drifter_2 computer (Win98, 2dn edition) CD-ROM drive letter is D:. Without having to use fdisk to change the drive letters, how can I resolve the problem. I thought mapping the drives might fix it, but I'm not very knowledgeable about networking so I thought I would seek your expert advice before I screwed something up.

Thanks for your time and effort!

Please e-mail me at: logo5@mindspring.com

Answer : Why would you try to access an audio track by double-clicking it? And also accessing an audio CD across the network (when it's on another machine) will likely not have the effect you are seeking (I'm assuming you intend for the audio CD in the remote machine to play on the one you're accessing it from). Audio CD playback is different from other types of audio like WAV and MID files. The difference being that, unlike WAV/MID files, audio CDs are not processed in any way - you simply start the playback of a CD or particular track and that DAC output is fed by a specific cable inside your PC to the amplifier section of your soundcard where it then comes out to your speakers. This is why you can start an audio CD playing (and if you set the options correctly in the player app to not stop playing on Exit) the CD keeps right on playing through a reboot (until Windows again scans the drive during boot).

In short you won't be able to play audio CDs from the other PCs CD-ROM drive. One way to get those same tracks, however, is to rip those audio tracks and encode them as MP3s (or leave them as WAV files and play those - but they're a factor of 10 larger in size). Try MusicMatch or WinDAC for easy ripping and encoding of audio tracks.

I do have a few more questions if you have the time. On my older computer (Drifter), I have a very slow MODEM. On my newer computer (Drifter_2) I have a 56K MODEM. Id like to be able to use the newer MODEM from my older computer. Also, I have a scanner on my newer computer that I want to be able to use on my older computer. How do I configure the system to use those resources in a 10BASE-T peer-to-peer (Win98 and Win95) environment?

Also, can you recommend some websites and books that are easily understood regarding networking in a peer-to-peer as well as a client-server type environment.

Thanks again for your time. Have a happy and safe 4th!!!

Answer : Modems and scanners are not shareable across the network in this fashion. What you *can* do is if 98SE is on the machine with the faster modem it can use 98SE's built-in ICS (Internet Connection Sharing) which will give you the ability to use that machine's faster internet connection across your LAN.

The best bet for using the scanner is to setup a share on your machine (C:\SCANNER if you like) - share it so the other machine (or you with a password) can access it. then take your document(s) to be scanned to that machine, scan them and from the scanner software save them to a drive letter you've mapped to your machine's "SCANNER" share (establish the mapping by right-clicking Network Neighborhood on the desktop and selecting "Map Network Drive").

A good beginner's book on networks is "how Networks Work" by Derfler and Freed.

Answer : To perform traditional "sniffing" and capture all packets traversing the net (in your area) would require that you be at you ISP or backbone provider's locations. Your local PC only receives packets that are destined for it - for your ISP to dedicate bandwidth to sending all traffic (ala "Ethernet shared segment") to all ISP users would be a security first and a horrific waste of their finite bandwidth. As far as sniffing the packets that *do* get addressed to you (which may have been what you meant anyway since you are concerned with "intrusion detection" (the sniffing part needed to be addressed, however) I don;t know of a way to go into "promiscuous mode" with 95 or 98, but with NT Server you can with a built-in tool (Network Monitor and the corresponding Network Monitor Agent service need to be added) or you can use a third-party program.

Subject : IP addressing scheme
Private : No

Question : Dear Sir

I am designing an IP addressing scheme for my network. I would like to use
subnetting and summarisations in the same. The routing protocol is OSPF.

The central location has 250 users with the ERP server. There are 3 plants
with 200 hosts each coming via leaased lines and VSATs into the central
server. There are 40 field units with 25 hosts each coming into the
central location. There are 20 more field units which do not come directly into the
central server, but come via a cluster head. There are 5 such clusterheads which
typically supporting 3-4 field units. The field units have either a VSAT or Leased line.
The field unit could have a leased line or VSAT. The Leased line would be either to the
clusterhead or directly to central server.The VSAT would invariably talk directly to
the central server.

Can you suggest an IP addressing scheme.?

Deepak


Answer : If you have a class B address you can this quite cleanly by subnetting the entire third octet, giving you an available 254 hosts per network. If however, you think the numbers may go above 250 at anytime, you may want to increase you available host somewhat by using more from the third octet.

Example class B address - 145.1.0.0
255.255.255.0

This would give you 254 networks of 254 hosts each. Enough for all your current field locations and larger plants. But not a lot of space for additional growth.

Same B address subnetted differently - 145.1.0.0
255.255.254.0

This would give you 126 networks of 510 hosts each which may be a better bet for you in the long run, giving those sites a chance to grow without bumping that upper limit.

Of course more than one subnet can be used at each location so you may still want the cleaner 255.255.255.0 approach since it makes the subnets and host addresses very clear and easy to use.

Private : No

Question : Since I installed a network card on my compuer I've got a problem with sockets. It is possible to connect to the Internet but as soon as I try to start a browser I get an error message that tells me there is no sockets available.
The same thing happens when I start jakarta-Tomcat WEB server.
I run Windows 98 Second Edition on my computer.

What should I do to make more sockets available so I can start browsers?

Thanks for the answer.

Answer : I would have to say in all my experience I have not seen this message under 95 or 98 (the old days of "Trumpet" WinSock under Windows 3.x are another story :-). I would suggest that something you have installed is/has either:

1) A buggy program that has usurped TCP/IP sockets irresponsibly.

2) A program (like the Tomcat web server) has replaced a system DLL that is necessary for proper TCP/IP stack operation.

Two things you can try to remedy the situation:

1) Remove and add back in the TCP/IP protocol completely, rebooting between removing and adding it back in. This may very well replace the version of a changed DLL.

2) Reinstall Windows over the top of your existing install (try #1 first, obviously) - this will not replace your installed programs or Start menu, but may allow Windows to rectify the missing/bogus files.

I type another username and password and I still can use the network.
I think that only if I know that password I can use the network.

Answer : Depending on what's installed network-wise Windows may be asking for more than one id/pw combination. The one that you get after the initial install when there isn't even a network incolved is a Windows logon, and is used to setup a repository for your desktop settings (icons, wallpaper, and other preferences). If you add a network you will be prompted for *that* login first by default - if the id/pw is the same as your Windows desktop account (you should make it so) then you will only answer the prompt once and Windows will apply your answer to the second prompt without showing it - if they differ you will have to enter both.

I had configured my network with, "Client for M/S Networks," a "Netgear AF310TX 10/100 NIC card," "NETBEUI (for my print server,)" and "TCP/IP." Also, the Netgear card and an IP address is confirmed in the "IP Configuration and Ethernet Adapter Information" when I check the "winipcfg" settings.

However, after I am online with my Netscape 4.7 for anywhere from a few minutes to a few hours, the network starts to act strangely, slowing down, and finally losing it's cable connection.

Now, when I check the "winipcfg," it shows that I now have an "NDIS MACLAYER V1.0" card. I've never heard of nor ever used a card such as this so I am totally at a loss as to why this is happening to a nice gal like me. I've run a complete Norton virus scan and it comes out OK.

I am running a cable modem fed to an 8 port Lynksys hub and haven't experienced any problems before this past week. The hub feeds 6 Pll/Plll computers. Four of the computers have the identical 10/100 Netgear NIC cards while 2 of them have the 3COM USB NIC adapters. The problems are happening to two of the computers with the Netgear cards.

Everything was fine until recently, and I've done nothing that might be the cause of this to happen. No new additional software, peripherals, or hardware, etc.

Can you please help me?

Thank you,

Michelle Schultz

P.S. I've just lost my cable connection again so I'm now sending this through my 'stand by' dial up modem.

Answer : I suspect the network card drivers. This sounds like a faulty driver that is leaking memory or resources since the problem creeps up on you like that. The quickest and easiest way to begin is by downloading the latest drivers for that particular card here:

http://winfiles.cnet.com/drivers/network.html

Then remove all items in the affected machine's Network control panel (noting any particular settings like static IP addresses, DNS, etc) first. Then reinstall the network card with the new drivers and add your settings back.

Subject : Multimedia Speakers

Question : I recently bought "Amplified Multimedia Speakers SP-120 AC110V" from Office Depot, I got home and there are no directions on how to hook them up to my computer. I know nothing when it comes to doing this type of thing - could you help please?

AJ

Answer : They should have a plug that goes into a wall outlet (for power). The other end of that cable should fir into a power connecter on one of the speakers (in the back). That speaker should in turn have a cable that goes from itself to the other speaker (might says something like, "To Left" if it's the right speaker we're talking about). Finally there will a last cable that is the input to the speakers and must also be connected to the sound card output of your machine (you *do* have a soundcard I hope). Look for the sound output on the back of your PC - if your sound card was added as a add-in card (most are) you will likely find that the sound card is the one with more ports than the other cards - it will likely have a 15 pin, two-row connecter for a joystick and at least two or three mini-din (small headphone style plugs) connecters. Identify the output one and plug this final cable there.

Question : WHEN I DOWNLOADED NAPSTER TODAY I THOUGHT EVERYTHING HAD GONE SMOOTHLY.UNTIL AFTER THE SETUP AND REBOOT,I TRIED TO RUN THE PROGRAM AND I RECEIVED AN ERROR BOX ON MY SCREEN,READING THAT THERE WAS A MISSING WININET.DLL FILE MISSING FROM MY HARD DRIVE. MY QUESTION IS HOW CAN I OR WHERE CAN I DOWNLOAD THIS SPECIFIC FILE FROM?

Answer : I'm assuming you're using Windows 98 so I made a copy of the wininet.dll file available for you at:

http://members.home.net/iqueue/wininet.dll

First make sure you don't have another copy on your hard disk - open a DOS prompt (Start/Programs/MS-DOS Prompt) and type:

c:
cd \
dir wininet.dll /s /a

If nothing comes back that's good - if one is found let me know.

Download the wininet.dll to C:\WINDOWS\SYSTEM

Then try your app...

Subject : some questions with web servers
Private : Yes

Question : What kind of servers would dot com companies like Lycos and any other big dot com company use to get their content on the web and on to our computers?
I know there are some servers that interact with a group of computers like in a school computer lab
but i would like to know about the kind that any one could access.
I just registered a domain name and i want to put my company on the web.
I know i need to buy a server but am confused as to what kind.
I know that servers commonly run unix but can my code be transfered from my windows os to the unix run server effectivly or at all?

Once I have a server what network does it connect to in order to provide viewers access to my pages?

What kind of bandwith has to be running through my server in order to provide content?


sorry if these questions were kind of long but i have to know this stuff to get the company off the ground
thanks allot

Answer : If you want to compare what different companies are using for web servers just pop in their web URLs into this site and it will tell you:

http://www.netcraft.com/whats/

So for example I put in either www.lycos.com or www.lycos.com:80 (port 80 being the http port) and got:

www.lycos.com is running Microsoft-IIS/5.0

So Lycos is using NT Servers running IIS.

Be aware some companies farm out their web hosting (something you want to consider since you are new to this) and pay a separate company to host their domain name for them. This saves you the troubles of picking and buying hardware, configuring and installing the operating system, setting up backups, installing the web server, building the web pages, and on-going maintenance and support costs (IT staff).

If you're still intent on doing it yourself I'd suggest you hire an IT person(s) or at least a temporary consultant to do this up-front work for you.

Subject : class b range
Private : No

Question : I have a Netware 4.2 server on a stand alone network with no other devices on that network. I am trying to assign it an IP of 192.168.10.1 with subnet mask 255.255.0.0
Netware doesn't like that. Not until I change 192 to anything else, will it work. ex... I change it to 191.168.10.1 with 255.255.0.0 and it took that just fine. Or if I keep 192.168.10.1, I have to use 255.255.255.0 Does Netware have 192 locked in to be a class C range and won't let me use it as a class B? Or am I just missing something obvious?????? I want to set this network up to use the standard class B IP's for internal use, but this doesn't look good.

Thanks.

Answer : 192 *is* a class C address IIRC.

0-127 is a Class A
128-191 is a Class B
and 192-2?? is a Class C

Since the 192.168.10.1 address you were assigning *is* a class C it necessitates at least a class C subnet mask (255.255.255.0).

Alternately you can do what I do and use the other range the InterNIC reserved for internal LANs - the 10.x network. Far clearer than 192.168 IMO...

For example:

A fake class B with it:

10.1.0.0
255.255.0.0

There you go... now you can use addresses internally from:

10.1.1.1

to:

10.1.254.254

FUQuestion : We have an existing WAN network setup as 192.168.0.0 with 255.255.0.0

We are trying to get our internal networks onto that same scheme. You don't recommend going into the netinfo.cfg file and changing the subnet mask there since it won't let me do it in Inetcfg.

Thanks.

Thanks.

Answer : My question would be - why does a web server with 1/2 GB of RAM need swap in the first place, much less twice it's real RAM? What else is running on this machine? It sounds like a runaway app or driver is allocating memory and not giving it back. Is this machine rebooted once amonth or so? Does this problem only appear after running for a long time?

Question : Hi Paul,
These past few weeks my Hp Pavilion 6330 lags even when I am doing the simplest tasks (typing). Here are the specs:

333mzh
96 megabytes of RAM
4 gigabytes Hard drive

So you might be wondering why does it lag at all? I'm just as confused! I have defraged it twice in the past week, I formated the C Drive (the only drive) 3 times! Right now it is lagging as I am typing this, and I have nothing installed on it. I'm really about this sudden change. Can you help me?
Jay.

Answer : Check for spurious applications that run in the background. The easiest way to survey these is to examine your systray (bottom-right) for extra icons representing these types of apps, and then press CTRL-ALT-DEL once to see the list of running tasks. This list will include the items in the systray *plus* more that are not visible onscreen (like explorer.exe and the systray itself). If you see more than 3 or 4 of these in the list it may be time to start disbaling things to free up some resources (both memory and CPU time). You can start by uninstalling unneeded apps that occupy the systray or that run and you have no need for, and continue by right-clicking on some in the systray and disabling the autorun ability on some that you want to keep (Real Player, AOL and others like this are notorious for setting their items up to run in the systray).

I only had a few icons in my systray, so I don't think its that. I also press Ctrl+Alt+Delete and looked at the list. Its very long. There's about
12-15 things depending on what I'm doing. Here's a list of the basic things:

Explorer
Rnaapp
Rundll
Pwstray
Systray
Vshwin32
Inetshar
Winampa
AIM

Could you tell me which one(s) I can delete.

Answer : If not needed the se can be removed (and taken permanently from regedit in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run if you never want to have to remove them again).

PWSTRAY
INETSHAR (Internet Sharing)
vshwin32 (Virus scanner)
WinAmpa (WinAmp tray control - unneeded)
AIM (AOL Instant Messenger - optional)
RUNDLL - should not be there - probably hung

Here's something, yesterday I removed my graphics card from the computer and it runs a lot smoother. I guess that card was holding everything up, it was really cheap. Everything is great on windows but the internet lags really bad. It took about 2 minutes just going to another page, this is horrible! I have a great modem and I have never had trouble with it but I think this problem might be caused by the graphics card again. Is there anything that could be wrong.

Question : Hello

I have a compaq computer 233 mhz. I went to turn it on the other day but nothing happened. I took it to a repeair shop and they think the mother board is blown. I have just removed the battery and noticed it is dead. Could this be the cause of the computer not booting up and fan not working. I have checked the power supply and it is fine.

Thank you

Answer : If you were running of of A/C current at the time I think the battery would be irrelevant. Of course if you were counting on the battery for power during these tests then the fact that the battery is dead could have a lot to do with it. :-) Try the notebook with A/C power only (take the battery out). If it doesn't work there then something else (besides the battery) is going on.

Subject : I can't connect my companies network

Question : Hello,

I have three PCs which are each using Win 98 (I have not networked the PCs yet) each PC has a Linksys 10/100 Etherfast LAN card.

I have just received AT+T Road Runner, which uses a 3Com cable modem, which I have attached to a Linksys Etherfast Cable/DSL Router (4 port Model # BEFSR41).

Each PC can connect to the Internet with no problems. However, I am trying to connect to my company via Nortel Networks Extranet Client each time I try to connect from any
PC (I installed the client on each PC same problem) I get the error message;
Failed to get DNS and WINS configuration information through the Extranet Connection. Connection closed.
Usually this error indicates that a firewall is preventing IPSecurity packets from reaching the Extranet switch

The troubleshooting I have done:
I dont have a software firewall, but the Linksys Cable/DSL is a hardware firewall.
I have checked the TCP/IP properties: DNS is enabled, I have a host name and my companies domain is listed, DHCP for WINS resolution is enabled, Obtain an IP address automatically is enabled and client for Microsoft Networks is enabled
I have done a winipcg everything appears to be all right and I can do a release and renew with no issues.
I have done a winipcfg on the NOC Extranet client everything appears to be all right and I can do a release and renew with no issues.
I can ping the server by name or IP address.
I have tried changing the media type from automatic to 10.
I have gone into the software for the Linksys Cable/DSL router and I change the setting there I can no longer connect to Road Runner
I remove Microsoft client, adapter, TCP/IP and added them again several times

I still get same error message.

Does have any suggestions or ideas?

Thanks in advance for any ideas or suggestions.

Thanks,
Bob

FUQuestion : I'm sorry to report that the URL you sent me would not work. Got an error message and that was the end of that.

I reloaded Solaris last night (fresh start) and can tell you this much. Both of my NIC cards are seen by the system, and have been given IRQ 10 and 9 respectively. Both have valid addresses, and show no conflicts.

If you attempt to ping the address I set up for the first card 192.168.10.6 the system attempts to ping from 127.0.0.1 which is because it doesn't recognize the NIC's.

Found some stuff about IPV6 and changing NIC's and it said to rename hostname.driver to hostname.newdriver

My etc/hostname file contains my hostname and nothing else... It is named hostname with no extention.. probably because no NIC driver was ever found to match the FA310Tx's

I changed the filename and went to terminal screen and typed: touch /reconfigure followed by a reboot command. The system went down nicely, and rebooted. But no joy. The hostname appeared but during the preboot, the rcis showed no interfaces up...

Do I have to remove the devices and start along another path?

Answer : The best way is with either of these tools - they will allow you, from any browser on any machine, to remotely control one of more of your PCs at home across your cable modem:

Free (VNC):
http://www.uk.research.att.com/vnc/

Costs (RemotelyAnywhere):
http://www.remotelyanywhere.com

Once you are controlling one of the machines if all the others are sharing their disks you can get at any data on the whole network. At that point I run a browser on the remote machine and use http://www.freedrive.com as a repository for any files I need from the home machines. FreeDrive gives you a web-accessible "hard disk" of 50MB in size, so it's large enough for almost anything you might need to shuttle between home and work, for example.

Subject : Changing careers
Private : Yes

Question : Hello,

How are you? I was just wondering if you could help me with a very big decision in my life right know. I am 28 years old and have decided to change careers from my current profession as a bank branch manager into the IT arena. I am fairly competent in computers on the software side, but do not like programming in great depth. I am currently going back to college and am pursuing a B.A. in Computer Info Systems with a minor in Bus. Adm. I was wondering if this is a good major to break into the IT field with? I would like to be a systems analyst or a network/database administator. I was looking at techies.com and saw all of the certifications they offer. I was also wondering if i should try to get these certs. and which certification tests I would need to take first, and if they would help with employment opportunites. Lastly, I was wondering if my 5 years in the Financial Services/Banking world would help me at all in the systems analyst or overall IT world. Any advice you could give me would be greatly appreciated, since investing the time and money to go back to school is so great, while juggling a family too. Thanks. RSG.

Answer : I think the degree will be a great way to get you in (and keep you in) the field. Unlike a certification a degree doesn't "expire" and it takes a much larger and longer effort to obtain. It also says a lot more about your skills since you focus on *many* areas, not just tunnel-vision on one.

Your business experience will serve you in good stead in a traditional systems analyst role.

Your best bet is to get internships while in school so you can hit the ground running with experience right after graduation. Many schools already have depts to handle these types of scenarios. Check with yours...

Answer : That sounds like your file allocation table got hosed - make a KNOWN clean startup disk on another 98 machine (Add/Remove Program control panel/Startup disk tab) and then after booting from that floppy (with it write-protected) do:

fdisk /mbr

That will remove the virus from the master boot record. More info on this virus:

Question : I have a computer it's a pentium 75mgz and I formatted the c drive because I was giving a lot of error messages. I can't get the computer to boot off of the boot disks. If I boot with the NT 4.0 disk after the third floppy It tells me that there is a DOS file It cant find and it ends the set up.
It will not read the CD-ROM are do anything. The setup disks show the DOS files on them but I am not sure what to do to bring the system back.
I made a new boot disk from my other computer and it says that it is missing a file also.
What can I do?
Thanks Ed

Answer : Did you create the boots disks again from the CD? If not try this:

Take 3 blank floppies and the CD to a working machine and then in a DOS prompt:

X:
(where "X" is the drive letter of the CD-ROM)cd \i386
winnt /ox

That should create the install floppies from scratch off the CD. Then tell me if things don't go better.

Subject : Subnetting
Private : Yes

Question : Hi Paul, I have a ip address on my machine with 192.168.0.1 with a class C subnet. Do you think that this ip address falls within this category.

What I think is that the third octet must be a number instead of a zero- or I could be wrong.
Does this ip address fall within the rule of a class C network? Thanks you for your help.

Answer : Technically speaking this address is a class C address, but I often see people refer to this like it's a B (by them using a subnet mask of 255.255.0.0). Since this range is reserved 9along with 10.x.x.x) for internal LANs that will not corectly be internet-addressable you can do with the last two octets as you please.

The cleanest way to use it if you don't need more than 254 workstations/devices on your network is to treat it as the class C that it is as in:

IP range - 192.168.1.1 to 192.168.1.254
subnet mask - 255.255.255.0

"0" and "255" have special meanings in an IP address so it's best to not use them at all.



Rating : 5

FUQuestion : Hi Paul, I've got your detail answer. Since this ip address which is 192.168.0.1 is actually a class c address, what makes it different, I mean why can we use 0 as for this subnet mask. Is it how the rule of subnetting has been follow?
My company is using this ip address for local area connection and I am confused myself to why it is being used. Is it possible that they are using the wrong ip or maybe it is a legit ip but appeared differently.
Explain to me why the 0 or 255 don't have it place in the subnetting class. Thanks.

Answer : Since the 192.168 is reserved for internal LANS it doesn't matter *what* you do with it as long as you are consistent within your LAN - heck you can start subnetting at the second octect if you wanted to:

Network 192.0.0.0
Subnet 255.0.0.0

But there's no need unless you have gobs of machines - the key is the network needs to be in sync with your subnet mask.

So if you guys are using 192.168.0.0 and 255.255.255.0 then you can (and probably *are*) making subnets like this:

192.168.1.0 (network "1" with up to 254 hosts)

192.168.1.1 to 192.168.1.254

Then another subnet of 192.168.2.0 and so on...


The 192.168 and 10. network addresses are used when:

1) Companies want to have internal machines be routed to the internet through a proxy server or NAT.

2) Companies don't want each desktop to be directly addressable on the internet for protection's sake - would make prime candidates for script kiddies to hack into...

3) Companies are too cheap to buy a class B or C address (if there's any left!) to put all the machines on with routable addresses.

The 10. and 192.168 are known to be invalid internet addresses - the first routing device that sees one send a packet it's way will drop it. That's the good and bad for the reasons I described.

As for what 0 and 255 mean they both refer to broadcast mechanisms - 0 was an onlder method that is no longer used, but it is still reserved for other uses (not that anyone uses it but in case they need to it's wise to avoid using it). A packet sent to:

192.168.255.255 will be seen by *all* workstations and is called a broadcast. This is how you get information to all machines on a LAN without addressing each individually. That is why you don't use it as a network address.

I found a computer user on the list of computers online and want to communicate with him directly. The campus is big, I know the person, but don't know where he is. Is there a way I can connect to him and talk to him via the network we're on? Do I need any programs?

Thanks very much!

Answer : There is a built-in utility for this - assuming your buddy at the other end has the component installed (and running) you should be able to send him a message. To check for yours being already installed do a:

Start/Run/winpopup.exe (hit ENTER)

If it runs then you're good to go - if not add it from the Add/Remove Software control panel/Windows Setup tab/System Tools/WinPopup

Then to send him a message in WinPopup click the mail icon or Messages/Send and type his machine name in and type your message.

Question : Hi Paul,

After 10 years in the Health Insurance Industry, I have finally decided to follow my passion...I/T. I have a little background in Computer Science (basic, fortran...), am mechanically inclined, and analytical. I have decided to obtain my MCP, followed by my MCSE (i have never heard of an A+ designation, what is this?).

Recently, i was offered a job with an engineering firm that installs network cabling and othe connectivity devices. Would this job be good experience, and/or a good way to get started in this industry?

Thank you for your time, and opinion.


Answer : An A+ certified person is a hardware technician, who also knows a bit about operating systems.

As for the cabling job, I'd say no to that as experience for networking or systems administration jobs. Your best bet is to hire on as a desktop support person after getting your MCP, and work there while you complete your MCSE. Then segue into a networking wole from there. The wiring would be a good experience but is not very applicable to your choice of jobs later on.

Question : Hey Paul, How is life?

I'll get to the point.

What I am trying to do is network 3 computer together. All computers have Win98. How do I do this? What hardware/software/inteligence do I need?

Thanks in advance,

Andre

Answer : Please don't make normal questions private... this isn't about your prostate exam after all. No one else can read the interaction we have when you make a question private (thus reducing this answer's value to the AskMe population). Please only ask private questions when you *really* need to...

All you'll need for this is

the machines themselves with OS and networking configured

A hub or switch (100Mb preferred)

Cables to connect each machine to a port of the hub/switch

I suggest you use TCP/IP as your only protocol and assign the machines addresses as follows:

10.1.1.1
10.1.1.2
and so on...

Set the subnet mask on all to 255.255.255.0

Make sure the workgroup name is set the same for all machines - like "MyHouse" - anything really. Make sure you add file and print sharing also so you can get to the other box's resources. That's about it unless you are going to have an NT Server involved. You may also want to set one machine to be the browse master and the others to disabled or things can get ugly when only clients are involved. This is a settable checkbox on a double-click of the File and Printer Sharing for Microsoft Networks item in the Network control panel.

Question : I'm trying to help someone speed up their server. It's Win NT 4.0 server with about a dozen Win98 workstations. The server has 5Gb of storage, about half-full, and 130 MB of RAM. They use WordPerfect, MS Outlook, and have internet access. for the last few weeks, they claim the server response time is slowing, esp for e-mail.
How do they check and/or erase e-mail from the server? Is there any maintenance that should be done apart from Scandisk, Defrag, or cleaning up old files? Is is OK to Scandisk a network drive (I only ask because the defrage program wasn't on the server)

Answer : NT4 doesn't have a defrag program. There are third-party ones available though.

But before I would blame the performance degradation on fragmentation you might want to take a look at things first - use the Performance monitor to look at CPU, memory and swap file/hard disk uage and see if you are really running low on RAM and going to swap a lot. If you are a simple RAM upgrade may be all that is needed (double the RAM from 128MB to 256MB) to restore the previous speed. Have any apps been added recently that may have increased the footprint for the server at idle? I would examine these things before acting (but adding the RAM is cheap and is an easy step to ensure swapping is kep to a minimum).

I have copy the content of the win 2000 I386 content to the root of C drive. What I need to know is if in teh event that I install new devices, new protocols or new software, I would like windows to automatically look in the content of C drive and look into the I386 directories.
What I mean is I don't want Windows to ask me to to put in the Windows 2000 CD everytime I install something new.
Where in the registry do I edit this function?
Or should I say how do I go about making this happen? Thank you for you help.

jack

Answer : The best way to make this behavior occur in *any* version of Windows is when starting to build the machine you:

make a boot floppy with CD-ROM drivers, fdisk, format, xcopy*.exe, etc on it...

boot on the boot floppy

fdisk the drive

reboot on the floppy

format the HD partitions

xcopy f:\i386\*.* c:\i386\*.* /e

a:
sys c:

reboot on the hard disk and start the install from C:\i386

This will then be the source for files from then on.

As for doing this after the fact I used to know the location in NT4 but it may have changed - the path in 98 is:

HKLM/Software/Microsoft/Windows/CurrentVersion/Setup

and the key is "SourcePath"

You might want to do a search for either "SearchPath" or "i386" since either will likely get you where you need to go.

FUQuestion : Thanks You Paul for your answer. I thought about copying the contents of the I386 to the hard drive at first, but I have already installed Windows and some applications already. So it kind of too late.

What I have found in the the registry path: HKLM/Software/Microsoft/Windows/CurrentVersion/Setup, the source path said D:\ . Will it default to the D drive since D drive is my CD-ROM Drive. Can I change that path to C:\ or C:\I386 instead or whatever.
another thing is, if I did change this path to point to another drive, do I hve to change other settings in te registry as well? Let me know what you think Paul. I greatly appreciated it. Thanks.

Answer : That is the setting I would change from "D:\" to "C:\i386" and I don;t expect you'll need ti anywhere else, but you can certainly look for "D:\" elsewhere in regedit and see it if crops up anywhere else. In either event it should *not* cause any problems. It can only help (changing this first one you found).

I am having trouble linking my Win2000 laptop to my two Win98 desktops at home. All comps have 10/100 ethernet cards, and they are all connected to the same Linksys router. All connect to the Internet fine, but the Win2000 laptop can't get on the same LAN as the two Win98 desktops.
I have shared the C drive and done all I know to do with the laptop, but it just won't connect to the desktop LAN. Even though you can't be here to see the set up, any configuration tips you could give would be great!

Thanks!
Chad

Answer : If they all hit the net through the router then IP is working on them all. Are any of the ports on that router designated special, like an uplink port or somesuch? Have you tried only having three machines plugged in (one of them being the troublesome 2000) using only the 3 other ports? That would confirm that it was/was not that port. Then with all three loaded make sure you can ping/telnet to each machine from the others. Then make sure all are in the same workgroup. You also may want to turn *off* potential master browser status for the 98 machines. To do so under the Network control panel dbl click the "File and Print Sharing for MS Networks" item and select the item "Broswe Master" and choose "disabled".

Then reboot them and open the Network Neighborhood from a 98 machine and type (in the address field):

\\2000machinename

and hit ENTER. Try the same thing from the 2000 machine with a 98 machine name.

Question : Hi,

I'm new in networking and have been given a taks to build a small peer to peer network for 7 PC's.

1) My question is, if i need to connects all 7 PCs together using Win98, how many licences i might need to legally do that?

2) What does it means by resource sharing, does it include the operating system?

3) Is it possible to make a PC's functionality to a server like machine. If there is, can you tell me where to obtain the software or relevant info. what specification would it need to handle 7 PC's, ex: speed, storage cap, RAM ect.

4) What is your recomendation for making 7 Workstation peer to peer network Cables.

thanks for your information.

Answer : Hi...

1) You will need one license for each machine.

2) "Resource sharing" is just the ability of a PC under Windows to make available it's files and printers to other machines on the network.

3) It seems you are asking if you can make one of these 98 machines into a server. In a way the peer-to-peer situation you're building already makes each machine into a server *and* a client. The only real difference (conceptuially at least) is that you don't have a *dedicated* server that does nothing but serve the other machines. If you were asking instead what machine you could use to put Windows NT on as a server the minimum for NT4 that I would use is a Pentium 120 with about 4GB of storage and 32MB of RAM.

4) If you are going to make the cables yourself get some Belden cable (or any CAT5 ethernet cabling you like), a set of crimpers and some cable ends (RJ-45) and go to town. Wire all 8 pins the same on both ends of the cable. When all the cables are done plug one end of each cable into a PC's card and the other into the ethernet hub or switch.

Answer : Unless you have conflicts I can't tell you what the issue with the NIC is... neither 95 or 98SE have any settings that handle changing things for two NICs.

As for sharing software 98SE has a built-in one called ICS (Internet Connection Sharing) - install it from Add/Remove Programs in the control panel. I would not recommend it however. 98 does not make the best network server and this makes the other machine's net connect dependent on that 98 machine running right/staying running. This also taxes the 98 box when the 95 goes out. the better way is to build a cheap NT Server and install Sygate - http://www.sybergen.com

Question : I am currently changing careers. I am enrolling in a distance learning scholl to get my BS in MIS and need to know what certifications I could get while working on that the school I am looking into is aics.edu if you want to look at it. I have a network set up in my house and believe that si my strongest interest at this time but do like alot of aspects of computers it has been my hobby for a very long time . I had a IBM pcjr=) thankyou in advance Matthew Polster

Answer : Well the MCP/MCSE and CNA/CNE are always in demand and many folks are flooding into the Cisco certs as well (CCNA/CCNP/CCIE). Since you say networking is likely your interest I would go with the MCP (try to do the Windows 2000 track as the NT4 track expires soon). More crucial to you than a cert right now is getting some actual practice to go with the degree so you have a killer one-two combo when you go for your first job. Ask around the IT department for some internships where you can spend some hours each week doing actual work and being around people who do it all the time. It will do wonders for your perspective and may actually help you to fine-tune what you want to do.

I'm a career-shifter (from non-IT) doing some self-training on networking essentials via books & a CD-ROM course. I'd like to identify companies near me (Boston, MA & northern MA) that would offer a good environment for a newcomer to the field -- I've been told that a consulting company would be a good place to get started.

Would you have any thoughts as to how to identify these companies in my area? Web searches using "networks" & "massachusetts" and similar terms haven't been too helpful. I thought you might know if there's an association that would have companies as members, or something like that. Any suggestions are much appreciated!

Subject : Server Port
Private : No

Question : Dear expert,

Sorry. Here I post my question again.

I have several questions regarding port on a server. Until now I don't know what a port on a server is.

1. Is it hardware or just a logical port?
2. What is the value means? For example, port =25, port = 80 etc.
3. How a port can be used?
4. What are the other property of a port?
5. Is a port an object like any other objects? You know OOP.
6. How can I configure a port?

If you are trying to answer my question, I will certainly give a very good or the best remark for your answer. Also, I appreciate your answer. Thank you.

Sicerely yours,

Soelaiman Boenawan

Answer : A port is a logical abstraction that is used by the operating system (and network protocols) to segregate devices or services. At the hardware level a port is used to isolate the specific I/O ranges used by every hardware device. But I think you probably are after the port most people mean when they say it, and that is the network type port. This is a way to segregate services that are offered on a network. It is nothing more than an arbtrary choice of assignment (port number to service). How it works is like this:

You're one machine A and want to telnet to machine B. Telnet uses port 23. You run a telnet app and direct it to connect to machine B. A directed packet is sent to the address of machine B. When it arrives at machine B, machine B has an application that listens to incoming connection and, upon seeing the port it is addressed to, (if a program is assigned to that port) invokes the program to handle the request.

So you are using ports all the time you are on a network. As for configuring a port there is nothing to configure, except for configuring what program handles which port. Some have predefined ones - telnet 23, ftp, 20 & 21, nntp 119, etc...

Subject : Networking Windows NT, Win. '98, and Win. '95
Private : No

Question : We have 3 NT 4.0 Workstation, 1 win. 98, and 1 win. 95 computers, and are having trouble networking these 3 op. systems in a basic peer to peer using "Client for Microsoft Network". What are the best protocols for these? They all can see each other in the network neighborhood, but when I try to access an NT computer from a '95, I get " you must supply a password to access this computer", even though we never set a password to log on to any computers, and in the "permissions" of the NT computers, we do not have any password options selected for any of the computers. The Windows '95, and '98 machines are set up as "user level access control", with a specific computer to "obtain a list of users", but it keeps telling me that I need a password to access this computer. I have tried both "user level access control", and "share level access control" without any success. I do not want to supply any passwords to get into any computers, other than the password at start up to log on to the network. Any help would be greatly appreciated.

Jeff

p.s. By the way, where does the list reside, when a '95 or '98 "obtains a list" from a specific user?

Answer : The only way I know of to get no passwords to shared resources is by setting up an NT 4 *Server* as a PDC (Primary Domain Controller), and then having the machines all login to it. Once logged into the domain all accesses to any resource is controlled through this machine. What you have instead is a "workgroup" where no one machine is in charge - each machine is responsible for authenticating accesses to it's own resources which is why a username/password prompt is being given. Find a cheap PC and make it into an NT Server - this will give you seamless (and more secure) access.

The "obtain a list of users" you mention is used when you have a domain controller who has the list of domain user accounts. It would not be used in your current configuration.

Question : Hello

I have recently receive a tutorial question that i am not sure how to answer it and see if you can help me out. Thanks for your help

The question is:

"Consider Network Address Translation (NAT). Briefly describe the relationship in functionality between DHCP and NAT (i.e. in what ways can they be used to accomplish similar business needs, and in what ways are they different?"

Vin

Answer : DHCP gives out IP address to client machines.

NAT allows client machines with non-routable addresses to traffic on the internet using a single valid IP address on the NATing device.

You can combine the services so that:

the DHCP server automatically doles out addresses to clients from a non-routable network address range (10.x.x.x).

the NAT will route any packets destined for the internet from internal client machines across it's sole internet-capable interface (ISDN, DSL, modem, whatever).

Was there something else about them you need?

Subject : Question about winipcfg
Private : No

Question : When I go to Start > Run > and type in winipcfg, I go to the Windows IP Configuration. In the drop down menu, it says I have two cards - a Realtek (LAN) and the Linksys (Cable modem). The problem I'm haivng is that in the drop down menu, the Realtek card is listed first and the Linksys second. Because of this, I'm having problems sending files in IRC and also playing some multiplayer net games. I know that if I can reverse the order of these cards, I will be able to do the things I'm missing out on - I tested this theory by removing the Realtek card from the Network Properties and trying to send a file in mIRC and it worked fine.

However, when I restarted my computer, Windows ME automatically installed the Realtek by itslef and then prompted me to restart again. I did so and I unhappily found that the Realtek was first in the list again. Im running out of ideas on what to do. I've posted messages in newsgroups. I've searched on the web. This is really my last hope. Any suggestions on how to fix this problem?

Need More Information : Why does this machine have two network cards - is it serving other machines via ICS? If so that may be the source of the trouble and the configuration of ICS may be at fault (you have two avenues for network requests instead of the normal one that a client PC normally has).

http://members.home.net/iqueue

FUQuestion : Sorry for not answering earlier. Yes, the LAN card is serving via ICS and the Linksys card is serving as the cable modem connection. Configuration of ICS is not the problem; I looked at the software about 10 times already. Any suggestions?

Answer : Do both cards have a default gateway set on them? If so is it correct? For the card connected to the cable modem the default gateway should be the IP address of the cable connection. The other card's default gateway should likely be the address of the cable-modem-connected network card (192.68.x.x).


--
Paul Doherty
http://members.home.net/iqueue

FUQuestion : Neither card has a gateway set on it, so I tried what you said and it didn't work. The cable modem card wasn't able to connect to the internet, and I can assume that the LAN card wasn't going to work either. Can you still help?

Answer : Doh! I had a mistake there... the default gateway for the cable-modem-connected NIC should be the same as the address the ISP gave you for the cable modem. For example if your cable modem IP is:

24.100.123.211

The default gateway might be:

24.100.123.1

Try that and see if you get better results... (next time catch me when I haven't recently slept ;-)

Question : Thanks Paul. Trying to follow up on the Win. '95, '98, and NT networking. Here's the situation now. When I try to access a NT Computer from a "95, I get " you must supply a password to make this connection" resource:\\name of computer\ipc$. Nothing I type for a password works. I can access the '95 computer from NT with no problem. All are in the same workgroup using client for micosoft network, with netbuei and tcp\ip protocols.


Thanks,

Answer : Unless you have an NT Server and are using it as a PDC (Primary Domain Controller) you need to set all machines to be using "Share-level" access control to resources. On the 95 and 98 boxes set this as follows:

right-click Network Neighborhood and select Properties

select the Access Control tab and check the top option, Share-level.

Now to access a resource (shared C:\ drive) named CDRIVE on the 95 machine from the 98:

Open the Network Neighborhood and in the address field type:

\\95machinename\DRIVEC

and hit ENTER.

Subject : home network

Question : Ok here is my current setup.
I have the cable modem come into my roommates Win98se machine then I set up ICS on the second NIC on that machine and connect it to our hub. It dishes out 192.168.0.x IPs for all the computers we use. Now heres the thing. On one, or more, of my machines I want to run some server stuff, like maybe an FTP server to start. Now how can I do this? Can I set up the "server" for foward all packets that are trying to find a certain port to my computer? What I mean is, say our internet IP address is 100.100.100.100, can I tell it to foward all 100.100.100.100:27000 to my computers 192.168.0.2 IP address where my FTP server will be looking for stuff on port 27000?

Im also thinking of just getting a DSL router for our internet sharing, could I set that up as well to foward all traffic to my computer that is looking for the FTP site?

Can you tell me if there is a way to do this? Basically I want to be able to connect to my machine from the internet when Im not at home. Someone told me that I could use W2K and set up a Virtual Private Network over TCP/IP and connect to my network over the internet when I am away.

I know this is a ton of info, but can you just tell me what I can do? What is possible in my case?

Answer : I believe ICS has that ability...

Look under Sharing Settings in the Services tab.

As for the dedicated cable/DSL router - these too (the Linksys in particular from what I've heard) can do this port forwarding but I think the Linksys will only forward to one machine internally, and if set that way may impact the other machine(s) network abilities (could be mistaken here).

Your best bet here would be:

Setup an NT4 or Win2K Server with two NICs as a PDC and on it put:

Sygate (if running NT4) or ICS for sharing the network connection via NAT. Your network will perform better and be more stable on NT/2K than on a client box.

The benefits?:

1) Faster, more stable network connection.
2) No slowdowns or loss of service if another client PC is online (like would be the case with the 98SE box in your case when it's being used or rebooted).
3) Better security - all resources are secured by the PDC.
4) You have a community storage/print area in the server.

Question : Hi
I was wondering if you could possibly offer a few suggestions for my place of work. we are all STUMPED!!

The clocks on the computers will just change on a whim, usually an hour back or an hour ahead. and there doesn't seem to be any pattern or reason for it.

can you suggest what we can try to fix this problem...we use programs that need to use the correct time.

Some details about our computers...

-we are now running Windows NT..we were running windows 98 and the problem has been there before and after.
-we have a network of computers, about 10 in all, linked together.
-the time will change usually only on ONE of the computers and the others will be fine
-this time change will happen when the computers are left running a program OR if they are left just in windows
-we have checked the time/date section of the settings panel and we are in the correct time zone.

thanks alot!!!



Answer : It sounds like one of two things:

1) "Daylight Savings time" modes are somehow being switched, moving you back and forth an hour (may want to deselect that option on the clock (Automatically Adjust for Daylights Savings time)).

2) A server is offering incorrect timesync information. This doesn't sound like the case since you haven't mentioned using a server in your office.

The easiest way to fix this (if your machines are internet-connected) is to install an atomic clock app that keeps each machine in sync with an atomic clock on the internet. Here is an app that is free and does this:

Question : Good Day Paul, Hope your day went well.
I am seeking your expert advice to how I can resolve this confusion I have. I believed that everytime I seek for help and in doubt, you are the only one I can think of who can help me. I am desperately in need of your help Paul. I have been ask to set up a small network in a small store.

Descriptions of Existing Network
- 7 Computers consist of Win95 and Win98 using a Novell Netware 3.12 server environment.
- Network use DSl Router for Internet Access( No dialup required) using Netscape.
- Router is not attach to Novel server(Standalone) with 16 Ports 10/100 Tx Hub.
- All computers are set to obtain an ip address automatically from a DCHP server.
- All computers use DHCP from the ISP to access the Internet.
- DSl has one static ip address of 199.178.180.209
- Router gateway is 192.168.254.254

Question?
- I am adding a Windows 2000 Professional machine which will be acting as an application server to the existing network.
- All 7 workstations which consists of win 95\Win98 will also need to log on to this machine for uses of applications and file and print sharing.
- Windows 2000 machine has a preassigned ip address of 192.168.91.1
- DNS address for this Win 2000 machine are 209.150.200.10 and 209.150.200.15
- This Win2000 machine will also be used for dial up connection to transfer database file to corporate headquarter.
- I have changed all computers on the network to have an ip address of 192.168.91.2, 192.168.91.3, 192.168.91.4 and so forth.

* After manually assigning an ip addresses to all workstations, none of them can access the internet.
* I suspected that the ip addresses are conflicting to the ip address the ISP are assigning. Is that true?
* If that is the case, what options do I have. How can I configure this network so all computers can access the internet?
Please advise? I thank you for your efforts and expert advice.

Jack

Answer : Well you said you statically assigned your IP addresses for your 95/98 machines, right? If so then DHCP is not in the picture at all. And I doubt DHCP from the ISP is even available, much less being used, in this case since the address range you are using internally is non-routable (192.168.x.x) and can't pass the router anyway.

What you will need to get the internal machines out to the internet:

External port to DSL/CABLE/ISDN/WHATEVER needs valid IP address - sounds like you have this already (199.178.180.209).

Internal ethernet port on router needs to have an address in the same network as the client machines (192.168.91.254 would be a good one to use).

All client machines need to have their "default gateway" set to be this address - 192.168.91.254

The router must have NAT or PAT enabled and setup correctly (Network Address Translation/Port Address Translation) - see the manual for the router or the manufacturer's website for doco on setting this up.

That's it... get those items done and you should be in good shape. Take things a step at a time (like get the IPs on all the clients done and then test that they can hit each other, then move on to getting the Windows 2000 machine setup for what you want to do, etc).

Subject : Career choice: Unix/Linux vs. Windows
Private : No

Question : I'm a Network Engineering student at a local Tech college, and we have been recently introduced to Linux/Unix. I'm having a somewhat difficult choice deciding wether to concentrate on Unix/Linux or stay with Windows and its W2000 MCSE track. I really like Linux, but I know the money it's easier to come by in this Windows world. Eventually I would like to be knowledgeable in both, but time and monetary resources don't allow me to do so. What do you suggest?

PS If I go with Linux/Unix, how do I break into that field?

Thanks in advance.

Answer : That's a dilemma facing many prospective entrants to the field. I myself have done both of these and Novell Netware too, and I currently do UNIX (Sun) administration. I agree that the jobs are more plentiful in the Windows arena, but the pay on the UNIX side is as good or better. I wouldn't let the money be the deciding factor though - pick the one you enjoy the most, and that has the jobs you want. If you go the UNIX/Linux route spend as much time as possible with the major player UNIXen (Solaris, AIX, HP) and less time on Linux if you can. Linux is nice but until it matures some more and makes more inroads onto the big hardware it's still mostly an x86 thing, and that makes it far less desirable than the big iron from IBM, Sun and HP. If you simply can't get a hold of any of these then Linux will do for learning purposes...

As for breaking into the field it's just like it's always been - you have to overcome the perceived need for experience with your educational/personal experiences. So take as many classes on the one you choose as possible and see if you can get a Summer internship with a company doing some Jr Admin work - that plus your degree will make it a lot easier to get your first job - from there it's no problem.

Best of luck!

Question : I having random lock-ups (ctrl+alt+del dosen't reset) have to use the reset button. I turned the hardware accelerator down to none, but lock-ups still occurs when opening two-three applications at once. it a thunderbird 850 with a ati 2000 expert pro. the mainboard is a via KT133 chipset. the video and the nic card are sharing irq 11--could this be the problem?
thanks

Answer : I doubt it but you could pull the NIC to test. Usually IRQ sharing is not a problem with modern motherboards and cards.

Are you overclocking? I would check for voltage and any other BIOS settings that may not be optimally set. If you are overclocking I would suggest jacking back down to stock for the time being while you isolate this problem (note - if the problem disappears when you lower the speed, you've found the problem ;-).

Question : Newly training in network admin... currently have CNA 4.11, leading to CNE. No previous network experience, but working with PC's for 10 years as a USER... I have 15+ yrs experience in business admin.
What are the REALISTIC job prospects for an entry level CNA/CNE, with no other certifications? I don't expect a 6 figure salary, and expect to start at the bottom somewhere, so my own expectations are pretty realistic I think.

Answer : Hehe Less than 6 figures? Got that right! :-)

I would expect a CNA alone could land a Jr Admin job at a Netware shop. Expected pay - around 35K/year.

FUQuestion : Thanks Paul, and glad you saw the humour in the 6 figure part!
30-35K was around where I was thinking. In your own experience, is there less demand for CNE vs. MCSE, and why since Novell still holds the predominant market share of OS's...?
Is it just the marketing guru's at MS that lead us to think that MS is the only way to go, or is there really that much more demand for MCSE?

Answer : It's typical marketing mindshare-speak. Whoever has the mindshare and is "growing" in popularity is seen as the way to go, even though, as you said, Novell's installed base is larger. People invest 6 months - 2 years training for these types of jobs (plus time on the job) and I guess they want some warm fuzzies about their job propects in the end. If the market is good for CNE where you live by all means go for it!

Subject : Disaster Recovery
Private : No

Question : What does the term 'disaster recovery' refer too. Also what are a list of issues that are involved in disaster recovery. Obviously backup is one: what other steps are taken to avoid a disaster and/or recover from a disaster.

Answer : Backups are the big one, but it's not just backups. It's *offsite* backups. Having regular backups taken away from where the servers are located avoids them being destroyed by the same "disaster" (fire, flood, tornado, whatever) that destroyed the server. Another major component of DR is having step-by-step documentation on how to recover a server and it's contents so that anyone with the requisite knowledge can get the machine back in order. Having a contact list for expedited hardware is also a component of a DR plan - you have to be able to get the hardware in ASAP so the downtime is kept to a minimum.

aaron


Answer : If you have a PDC you need to make each machine log into that PDC (joining each machine to the domain) and then add "File and printer sharing for Microsoft networks" to each client machine (network control panel). Once done sharing a directory or drive can be done by right-clicking the item and selecting "Share" then adding the users at the level of permission you want.

Let me know if any of this needs clarification.

Question : I,m a bit confused about network architecture. What is the difference between mesh (interconnected), tree (hierarchical), star, ring, and bus.
Thankyou.

Answer : Bus is a straight line cable connection with "taps" at various points where a PC can be connected.

A Star has a central connectivity device with cable connections radiating from that device to each connected machine.

In a ring each machine has a set of in and out wires and passes the signal around the circle in a round-robin fashion. Sometimes accompanied by a "token" - the machine possessing the token is the only one allowed to talk at that moment.

Mesh is just a network whereby every machine is connected to every other machine. Obviously not feasible with more than 4 or 5 machines.

Never heard of a tree topology.

Question : What I want to know is; which computer field will most compliment my M.B.A. I worked very hard to obtain it and it has yet to "pay off " (not just monetarily). I am currently considering a school which offers year long programs in both Networking and Programming fields as well as a program geared soley at Cisco up to the CCNP level. The other networking program consists of A+, MCSE,Cisco CCNA, Network+, Novell CNA 5.1. The programming course consist of client server concepts, fundamentals of C, Oracle 8x.VB6.0, Developer 2000, Visual Basic 6.0, SQL SVR 7.0, MTS, Solutions Arch. Desktop with VB 6.0, HTML, FrontPage 2000, Visual Interdev, Javascript, ASP, COM/DCOM, DHTML, UML, XML, SQL. The cost of the courses are identical. Which program would you consider to be the most complete or benificial to my circumstances; if any. I have always wanted to get into the computer field but I am hesitent because I don't want to get another education that I can't use. Do to my lack of experience in any thing other than construction or the Military----most employers want me to start at 35k but 40k is my absolute bottom line do to financial and family obligations. I will be looking for work after completing one of the programs in the New Jersey / New York area.

Thank-You for your help..

Answer : You are looking at three widely different fields - programming, networking, and systems administration. You can make the money you want in any if these fields without any trouble so I would say to simply pick the one you're most interested in and sign up! As for your concerns about investing in another education that will not pay off you can rest at ease knowing the IT market is one of the best of all job types with the best growth in numbers of positions and in pay.

Question : What is the difference between AMD "duron", Intel Celeron and Pentium Processors? I hear different speeds with different processor. It is the same speed at 700Mhz using, Duron, Celeron, and Pentium? or is there a difference?

Thanks a lot for your help

Answer : There will be differences for sure, as the CPUs are quite a bit different. Without going into a lot of detail clock speed (Mhz) is important but does not tell all about a CPU. Some CPUs have more on-board cache which helps speed up repeated or upcoming operations. Others have longer or shorter "pipelines" which are accelerated areas for instruction execution. But even with the differences the performance of all three will be fairly close - the Pentium 3 will be the speed winner between these three for most real applications and games due to it's larger on-board cache. A Celeron II is a P3 with half the L2 cache (128K versus the P3's 256K) and will run similarly.

Subject : password synchronization
Private : No

Question : Hello, I have a question about password synchronization.
I several windows 98 client machines logging into a mixed novell and NT4 network.
The windows 98 clients have the netware client 3.3 installed as well as the microsoft client they run both ip and ipx protocols. The primary network login is client for netware 3.3. The machines are authenticated by the novell server first then the NT server.
Most of the time there are no problems, but however issues arise when the netware password has to be changed. When the user logs they are asked to change the netware password, this they dutifully do, and the windows passsword is also synchronized.
However the NT password isn't, this confuses the user and they either enter the old password or cancel the nt login.
I am wondering if there is a way for all the passwords to be syncronized at the same time like the windows password is.
I can not afford to install nds for nt or migrate our pdc to 2000.

Any assistance would be greatfully recieved.

Kind Regards
M savage

Answer : This person believes this to be a known issue with MS and they have a DLL update that fixes it:

Another person offered this as a work-around:

use the Network-password with the NT-server, but make sure that your Windows password is set to nothing,
just blank.
When you are prompted next time to change your network-password, no need to change anymore your
windows-password

Question : I have two desktop computers. Dell recommended that I use a home network that plugs from the computer into the home telephone line. I am planning to run a dedicated phone line between the two computers. Should I use a standard phone line or go to something like a "monster cable"?

Answer : I would recommend that you *not* use the telephone line network devices. They are slow and non-expandable. If you only need to connect two machines you can buy a single Ethernet cable called a "crossover" cable for a few bucks and wire straight between the machines with that. Benefits are higher speed and the ability to use the Ethernet cards later on if you add more machines.

Question : Hi pauldoherty

I am trying to teach myself(learn somthing more)
about a Networking so I was wondering if you can help me I with these problems, if you can explain it to me. Anything will help...

Thank You very much!

1)Consider a packet sent across a bridged LAN to a nonexistent address. How far will bridges forward the packet?

2)Organizations that can afford the best network
equipment usually choose switches instead of hubs. Why?

3)Can a bridge connect Token Ring Network to an Ethernet? Can a Switch? Why or Why not?


Answer : 1) I would expect that bridges, being devices that only work at the data-link layer, would not pass a packet destined for an address not on either side of the bridge at all, since they have no knowledge of any other machines.

2) A switch is just like a hub with one important difference. Unlike a hub where all ports share the bandwidth on a continuous basis, a switch has dedicated bandwidth for each port, creating a private communications channel for each port. This prevents collisions as we usually know them since no machine can interfere with another's ability to send data. This also allows full-duplex send and receive for all machines all the time, with the traffic aggregation being left to the switch's internal programming to pass the data when possible.

3) No in all cases - that would require a gateway. An ethernet and token ring network use completely different singalling and access methods and thus are not compatible. For example on an ethernet network any machine can transmit whenever it desires. It simply listens to see if the wire is in use, and if it isn't transmits it's data. In a token ring network a "token" is passed from machine to machine and only the machine currently possessing the token can transmit data.

If you know where the sharing tab could be if you would let me know it would be great...thank you again.

Answer : It will appear here (Windows 95/98):

right-click Network Neighborhood and select Properties

In the Configuration tab look in the list - if "File and printer sharing for Microsoft Networks" is not listed then click the button at the bottom called "File and print sharing" to add it.

Under NT if you are joined to the domain I think it will already have the Sharing option if you right-click on a disk or folder. open My Computer and then right-click the C: drive and look for "Sharing". if it isn't there then follow the same steps above for the 95/98 machine except under "Services" click add and find the correct service.

Answer : The easiest (and cheapest) way would be to ZIP up all the files you want to tracnfer into one large filename that adheres to the 8.3 naming standard (MYFILE.ZIP) and then transfer the file between the machines with this utility (needs a null-modem serial cable - pick one up at your local computer store):

http://members.home.net/xport.exe

The program is dead-simple to use - just connect both PCs, power them up to a DOS prompt (hold CTRL while it boots to get menu and select Command Prompt Only), and then run xport.exe on each. Then pick the file to transfer.

Subject : information systems as major in college

Question : Hello. I'm currently a freshman in college right now majoring in Computer Engineering. I always thought that Computer Engineering dealt mainly with computers. However, I'm finding out now that lots and lots of electronics are involved with computer engineering. It's becoming a hassle to try to be "interested" in electronics. I love computers, but when it comes to playing with chips and wires and measure voltages, it's such a nightmare. I'm thinking of switching my major to Computer Science or Information Systems. Basically, what I love to do is experiment with computers and it's sofwares. I think computer hardware just deals too much with electronics and I hate it. I love the internet and love how computers can perform so many things for us. I was wondering if you could give me any suggestions on what I should do. The main issue is I don't know what kind of major "Information Systems" is. Is it a good major? Are there actually jobs out there for Information Systems people? I never really heard of them, but when I look at my college undergraduate guidebook, I see lots of computer-related topics I'm extremely interested it. Immediately after I saw all the aspects of Information Systems, I just wanted to quit my computer engineering and electronic classes and switch right away. However, I'm not sure as to how strong of a major Information Systems is and I'd like to have any suggestions you may have on the major. Any tips are extremely appreciated. Thanks very much!

Kenneth S. Kwan

Answer : Information Systems differs slightly from the Computer Science programs typically in that IS degrees focus more on business processes and interfacing with people (as training for systems analyst roles) than CS does. CS is mostly interested in the theory and operation of computers and has little or nothing to do with business. If you want to be a programmer or OS professional CS is probably the way to go; if instead you would like to be a project manager or systems analyst the IS is probably the way to go. I would say you have already done the hard part of figuring out that what you are doing is not going to be enjoyable - now you have the much easier task of picking between two you know you like.

As for job prospects all areas of IT are good at this time and I see no reason to expect them to decline. Businesses and individuals are becoming more and more involved with computing and the demand for people who know how they work can only grow along with that increase.

Best of luck to you in your endeavors,

http://www.winzip.com

Right-click the files/dirs to be backed up, select "Create Zip". Then in the WinZip dialog choose the span option and put A:\WHATEVER.ZIP (name it whatever you like). It will fill up one disk, then ask for more as it needs to until the whole file is done.

Subject : modem

Question : How do I test a modem to make sure it is working?

Answer : open a direct link to the modem with a terminal app like Hyperterm (comes free with Windows). Open a direct COMx link (where 'x' is the number of the port where your modem is - COM2 for example). Then type in a few commands like:

AT

(should echo back "OK")

ati4

(should echo back info)

Try ati1, ati2, etc

If the modem is responding to any of these it's probably running fine.

If you have trouble with the terminal program I have a nice utility called "ATsend" that will directly hit a modem on a serial port. It's a pure DOS utility so I would reboot before using it and during boot hold the CTRL key to get the boot menu and select "Safe Mode Command-Prompt Only"

Then run

atsend i4 2

would send an "ati4" to the modem on COM2 and you should see the info it echos back on your screen.

Get ATSend from my website -

Question : What is a switch and what is it used for?
Ex: We have three routers and a "switch"

Thanks. Chad

Answer : A switch is like an ethernet hub, in that it connects workstations and other end-node devices to the network. But it differs from a normal hub in a few respects. Normal hubs share their bandwidth across all their ports, so for example an 8-port 10Mb hub has 10Mb to share over all 8 ports - any machine trasnmitting can use up to that amount of bandwidth, but when any other machine on the hub talks they begin to share that bandwidth. If all 8 are going at once the speed will drop to around 1Mb each (if evenly shared). A basic switch gets around this by dedicating each port a set amount of bandwidth, and by not blindly repeating (like a hub does) all incoming traffic from any machine onto the other switch ports. So a switch has a bit more intelligence (it is aware of the MAC addresses of the machines plugged into it) and assigned bandwidth per port so each machine can talk it's head off without impacting the other machine's speed or ability to talk. Some newer so-called
layer 3" switches also have routing ability and can direct packets to alternate networks. These devices begin to blur the distinction between "hubs" and "routers" as they can perform some of those tasks normally assigned to routers.

Subject : IP ADDRESSING
Private : Yes

Question : I have 100 computers connected to a group of ethernet hubs.
All of the computers are in the same collision domain.
There are four departments using these computers-. Finance, Marketing, Information
Systems, and Production.

All computers are using Windows98 and they are on a peer-to-peer network.
When a person from one of the above groups opens network neighborhood, I want them to only see the computers from their group.
I want the I.S. department to see all of the computers when they open network neighborhood.
What IP addressing scheme would you use, and what subnet mask would you use?
use 170.1O.X.X to have a starting point.

Answer : Each group will need to be a member of their own workgroup (e.g. Finance people's computers belong to the "Finance" workgroup (set in the Network control panel) etc... ). Then when they open Network Neighborhood they will see a list of the other Finance people's machines that have File & Print Sharing enabled.

As for seeing all the workgroups from the IS machines I know of no way to do that since each machine can only be a member of one workgroup. What you can do is type \\workgroupname in the address field of the Network Neighborhood and likely that will show them to you.

100 computers and 170.10.x.x

I would subnet (in case you add more collision domains) on the third octet.

All current machines get an address in the form of:

170.10.1.x where x is 2 through 254 (reserving .1 for a router)

Subnet mask will be 255.255.255.0

Subject : Primary and Backup Domains?
Private : Yes

Question : Can U help me (a rookie in the learning stages)explain the benefits of a PDC and Multiple BDC's on an NT network?

Answer : PDC primary function and benefits:

Primary Domain Controllers are NT Servers that are used for authentication of users and controlling access to computer resources both on it's resources and any user machines that log into it.

BDCs are just backup Domain Controllers. Their function and benefit is that they provide redundancy for authentications of users in the event the PDC goes down, and they provide speedier response since they can authenticate users while the PDC is busy with other tasks.

Subject : USER vs GROUP management
Private : Yes

Question : Explain why you would want to manage users in an NT environment with groups instead of by each user.
At what point would you add a new group and why?


Answer : I would add a group as soon as I have more than one user who have similar data access requirements. Groups exist to organize and *save time* plain and simple. If it will take you less time to add 10 users to a group and then add that group to 5 shares for access then you do it.

Question : In a peer to peer network, If I have a 100 node 1OMb/s switched Ethernet network and a 10 node 1OOMb/s hub (single collision domain) Ethernet network, which will have higher overall throughput and why?


Answer : I would say the 10 node 100Mb network will be faster. Two main reasons:

1/10 the number of users of the switched network.

Even if all machines are active the *worst* unidirectional bandwidth each machine gets is 10Mb. In cases where less activity is taking place any given machine can get up to the full 100Mb. Not so with the switched network, where the best any single machine can get is it's 10Mb pipe.

Now had you asked which network would be *more consistent*... :-)

As you are a network engineer, please tell me all about CCIE, and please let me know that to become a ccie, is any engineering background is necessary or accountancy student can do prepartion to become CCIE. What is starting salary of CCIE ?

Thanking you in anticipation.
yours faithfully
jack

Answer : I know what the CCIE (and CCNA) are but do not possess one of these myself. It is a certification for people interested in networking. You can specialize in various areas of networking in your CCIE. Here is some more info:

http://www.cisco.com/warp/public/625/ccie/

Anyone can learn the material given time. If your background is not in networking it will probably take you longer and/or be harder for you to master.

Starting salaries vary depending on who you ask, but estimates would be between 60,000 and 100,000. Be aware that the type of jobs associated with this certification will usually be a consulting type affair, with travel being a primary consideration as your skills are sold to companies needing installation or troubleshooting support.

Question : how many netware partitions are allowed per physical disk?

Answer : Only one Netware partition per physical disk (max of 4 under the newer Netware 5). Once the partition is defined you can create as many volumes as you like up to the maximum allowed by that version of Netware. So the rule is make the partition as large as you'll need for all Netware volumes you'll create.

Question : how is a hub used in networking computers?

Answer : A hub allows more than one computer to connect to a network. The network can be as small as those systems plugged into that one hub. The hub acts as a repeater of signals so any machine plugged into it can send data, and the hub will repeat that message across all the ports it has, meaning the recipient machine will hear it (if present on one of the hub's ports).

Question : Hi!
recently, i had decided to switch to broadband. So, i bought a new modem and an ethernet card, and log onto a local ISP. What I know now is that i am having a ADSL modem, logging onto LAN network... or something like that. The problem is,
1)ever since i got the modem, whenever i start windows, there will be an annoying prompt saying: "Microsoft client network. Please enter login name and password." It also happens whenever i log onto the net using conventional 56k modem.(u see broadband in my area isn't free.)
So how do i get rid of that message?

2)Secondly, ever since i got the ADSL connection, using 56k log on to the net is now very troublesome: i had to manually type in the password everytime i log on, and the save my password checkbox isn't working too.
Please help!!
thanx!!

Answer : 1) Remove the "Client for Microsoft Networks" items from your Network control panel (Start/Settings/Control Panel/Network). Also be sure the drop-down at the bottom says "Windows Logon".

2) The remembering of the password is linked to you logging in as the user who created the dial-up networking icon that connects you to the ISP. If you are bypassing the login prompt by hitting ESC or logging in with a different name the remember password will not work.

Question : My friend and I are trying to network our computers together WITHOUT A HUB I am running win 95 and he is running Win ME. I have the crossover cable needed. I was wondering if you could give me a DETAILED description of all the settings I must have in order for this to work. We want to play diablo 2 so I know we need tcp/ip, but do we need other protocol? I have been trying to get this to work for the past two days!!! I'm going nuts, I hope you can help. Thanks for your time:)

Answer : Please do NOT ask questions like this as private. Others will not be able to read our interaction and this detracts from the sharing of information. Please reserve private questions for truly private questions.

You're on the right track. I would add IPX/SPX to the list of protocols you use as many games still use it for LAN play. As for the settings for your TCP/IP:

PC #1

IP address - 10.1.1.1
Subnet mask - 255.255.255.0
Default Gateway - leave blank
DNS - leave blank
Workgroup name (under Identification tab) - MYWorkGroup

PC #2

IP address - 10.1.1.2
Subnet mask - 255.255.255.0
Default Gateway - leave blank
DNS - leave blank
Workgroup name (under Identification tab) - MYWorkGroup

Now you are set to play games with each other - you'll simply need to enter the other machines IP address to let him host a game (or vice versa).

Subject : What was going on--see letter
Private : No

Question : Hi:

I'm just a home computer user--on one computer.

Installing Virtual Pool 3 CD from Interplay yesterday I got the following message. I have no firewall that I installed; only Norton Anti-virus 5.0 and the instruction booklet that came with it does not mention a firewall. The message said to contact my ISP, but they said it was none of their doing and beyond that suggested I contact manufacturer help.

I decided to uninstall and reinstall first and everything went fine and I got no such message (quoted below) with this 2nd. install. The program worked perfectly.

I am eager to understand something the message said, however, so here it is. I am not myself on any network.

"Your computer's internal IP address (127.0.0.1) is different than its externally known IP address (64.184.232.152). This may be due to a firewall, NAT proxy or other unusual network configuration and it prevents most games from working properly as a host. You probably will not be able to host any game rooms unless you are the DMZ host on your network. Contact your ISP or network administrator for more information. You can disable this warning by turning on the firewall setting in the options dialog."

I understand that my ISP (my local phone co.) hands me a different IP # each time I log on but what is my computer's IP # all about? I had not realized I had one. And is it permanent? What does it do?

Any ideas as to why the message occurred with the first installation and not the 2nd? Perhaps I did something unintentionally and unawares that confused my computer or Windows 98?

Sincerely,

John D. Miller

Answer : It may be that in one installtion you were on the internet (dial-up was active) and in the other you weren't.

You are quite right in that you get a new IP on each connect to your dial-up ISP. As for your address shown by the program (127.0.0.1) that is what is known as the "loopback" address, and is used for internal stack communications. It is literally an address that means "this machine" - if you open a DOS prompt and type:

ping 127.0.0.1

you will see the host responds (and quickly! :-) whether you are dialed in or not, as you are pinging yourself! This is a useful test to confirm that the TCP/IP components in Windows have been properly installed when troubleshooting network issues.

in short the 127.0.0.1 address is perfectly normal and present on every machine that speaks TCP/IP.

FUQuestion : Paul:

You say I may have gotten the messsage I did the first time because I was on the internet. Does that mean I was on a network simply by virtue of being ISP-connected...I mean there must have been lots of other computers similarly connected to my ISP at the same time? Or to rephrase, why did being on the net cause the messaage to appear?

You note that 127.0.0.1 means "this lkmachfine". My computer and only lmnine. l Another computer with a TCP/IP stack would or would not have that particular number?

John

Answer : I said one of the installs may have been done while connected to the internet (likely the one in which the 64.184.232.152 IP appeared). Why the message occurred is anyone's guess and probably has more to do with the game's programmers making a mistake than with your machine. Have you tried online gaming with it yet?

As I said in the first reply *all* machines regardless of hardware or OS that use TCP/IP treat an address of 127.0.0.1 as a loopback. That means the packet you send out never even actually hits the wire - it is re-routed internally back up the IP stack without ever being transmitted. That is why it's a good test to see if TCP/IP is installed.

Subject : hub, but what next
Private : No

Question : Hello. I have a situation at hand. It is the following:

1) I currently have 3 computers (Computer A, Computer B, and Computer C).

2) I have an Ethernet Card for each of the three computers.

3) I have enough RJ-45 cables to connect them together.

4) I just bought a hub to network them together, but I'm not sure how I should do that.

5) Computer A is the one with the "internet connection." That is, it is the host of the internet for the other two computers.

6) The hub I have is the 10Base-T Ethernet Hub. It has 5 RJ-45 jacks in the back.

7) Four of the ports are labeled TP4,TP3,TP2,TP1. The last port is labeled Uplink.


How should I make the RJ-45 cable connections so that I can network all three computers together and also allow the Computer A to share the internet connection for the other two computers via a proxy server? Thanks very much!

Kenneth S. Kwan


Answer : If the machine with the internet connection connects with a modem you are all set if you have one of the following operating systems installed on it:

Windows 98SE
Millenium Edition (ME)
Windows 2000

All three of these have a feature called ICS (Internet Connection Sharing) - it is the feature that allows that machine to share its connection with the others. Get it installed and configured as your first step. We'll call this machine 'PC #1'.

Plug all three machines into ports on the hub (don't use the uplink port for now - it allows you to "cascade" to another hub if your outgrow this one - there is a button that turns it into a normal port too so if end up having to use it you can).

Assign the PCs the following information after you get the OS on them and the network card is installed:

PC #1

IP Address - 10.1.1.1
Subnet Mask - 255.255.255.0
Default Gateway - leave blank
DNS Servers - Put in the addresses supplied by your ISP

PC #2

IP Address - 10.1.1.2
Subnet Mask - 255.255.255.0
Default Gateway - 10.1.1.1
DNS Servers - Put in the addresses supplied by your ISP

PC #1

IP Address - 10.1.1.3
Subnet Mask - 255.255.255.0
Default Gateway - 10.1.1.1
DNS Servers - Put in the addresses supplied by your ISP

Make sure each machine is in the same workgroup - under the Identification tab of the Network control panel. This way you can also share files and printers on the network. For clean access to the Network Neighborhood make one machine the browse master and disable that ability on the other machines. To do both tasks you will need to add the "File and Printer Sharing for Microsoft Networks", then double-click it in the list and set PC #1 as enabled for browse master and the others as disabled.

Reboot all the machines and test from PC #1 that you can hit the internet (try a web browser). Then go to one of the other machines and try this from a DOS prompt (Start/Programs/MS-DOS Prompt):

ping 10.1.1.1
(should show replies, not timeouts)
ping www.cnet.com
(reply may or may not be received, but the first line should be like the next line)

Pinging home.cnet.com [216.200.247.132] with 32 bytes of data:

If you see the line above then everything is good, since you properly resolved "www.cnet.com" into its IP address which means you got past your default gateway and on to the ISP's DNS servers.

That should get you hopping!

Question : Hi

I have a laptop conneted to a peer network sharing an internet connection. The laptop has win98 loaded. For some reason win98 keeps installing the network card (xircom 56k/10/100 combo) twice and then on start up giving me an error that there may be a problem with the network card. I have tried deleting one of the entries but on start up it win98 re-installs it again even though it is already installed. I have tried deleting both including all network components, again on start up it is installed twice. I get one message startng the the card was found and being installed and one message that an unknown device was found and is being installed.

Any suggestios?

Need More Information : So you get two of the network card, or one for the network portion, and one device for the modem?

FUQuestion : Hi and thanks for the reply. I am not sure but I think that I do get one for each. I was confused because I get an error message on start-up.In looking at the Xircom support page there seems to be a known error with Xircom combo cards and IBM 760 laptops. I was in the process of trying to find the right patch when my broadband connection went down. Hopefully I will be able to log into tonight and see what happens. Thanks for the attention and please let me know if you have any ideas???

Question : hi, my names nic, recently, i brought a logitech quickcam express webcam, so that i could use netmeeting to talk to my girlfriend (i'm at university) I'm not sure which webcam my girlfriend has, but its not a quickcam express. When i was back home, we tried connecting, and we could get it to work (through a freeserve ISP connection), but since i've been back at university, it won't work. When we try to connect, my girlfriend can see me, but i can't see her. We can however, both use the netmeeting chat. We are using netmeeting v.4 (i think) We both have netmeeting set to send and recieve video, and we have disabled IP Header compression. My connection runs through a local university network. Thats all I know about it. If you need more information then i could try and find out. I would be grateful if you could give me any advice on how to get it working. Thank you very much for your time,

Answer : Your problem very likely stems from a firewall on your campus that is blocking the necessary ports for NetMeeting to use. Ask your campus network manager for assistance in getting the port numbers to use. They may have it blocked on purpose as it does use more bandwidth than browsing the web in general.

Answer : These services will usually involve a dish, a receiver/converter box of some sort, and an ethernet card (or USB plug) that goes in your PC.

As I said most satellite systems are one-way (meaning you can only receive data from them) while a few new ones (I gave you some links to them) support bi-directional transfers directly to and from the satellite, obviating the need for a dial-up account at all.

"the remote access server was unable to acquire an ip address from the DHCP server to be used on the server adaptor. incoming user will be unable to connect using ip.
please explain on what it means

Answer : Sounds like you have a misconfigured TCP/IP setting on the server or the client. Do you have a DHCP server running on the NT Server? You'll need one unless you assign a pool of static IP addresses in your RAS setup. Determine what randge of valid IP addresses from your network you are willing to dedicate to RAS connections (probably just a few to begin with) and either assign them under the RAS Server TCP/IP configuration screen, or add them as a reserved scope into DCHP Administrator. For example, say your network is:

208.212.32.0

You could dedicate the addresses between 40 and 50:

208.212.32.40 - 208.212.32.50

open the first URL I gave you above and do a CTRL-F and type DHCP and you will find a screenshot of where to configure this.

Question : What do you advice for secured files transmissions? SSH? And with which softwares?

Answer : Yes, ssh (Secure Shell) is a good way to accomplish secure communications. I use it for:

*slogin* - a replacement for telnet (can disable telnet after you get it configured)

*scp* - secure file copying (faster than FTP and secure - can show progress too)

*sexec* - secure remote execution (replaces rexec) of executables on another machine

Question : 1)I have 810 motherboard. I install red hat linux 6.1. It has inbuilt display card. My Linux window size appear very large. So I can work only command prompt.
I use Xconfigurator. But no changes. I also changes XF86Config file's refresh rate with following:-

Replace this line:- Modeline "1024x768" 75 1024 1048 1184 1328 768 771 777 806 -hsync -vsync
with
Modeline "1024x768" 65 1024 1032 1176 1344 768 771 777 806 -hsync -vsync.
But no changes.
Please solve this.

2) I have two system. One has windows 98 and other has red hat Linux 6.1.
Ping command run truly from both computer. Through smbclient I see window98 file in my linux computer. And from Network Neighourhood I see Linux file in window 98 computer.

But telnet does not work from windows 98 to run linux command in my window 98 computer. Both has telnet files.
Please solve this.

3) I have two system. One has windows 98 and other has red hat Linux 6.1.
I see linux files in window 98 network neighbourhood.
I select all files of linux's computer then see the properties by right clicking it.
I wondered, It displays 8.4 G.B. approx. But my Linux's computer Hard disk has 4 G.B. Capacity.


4)I run Linux startx. Press ctrl+alter+f2 to go to command prompt. Now startx command does not run while I does not restart Linux. It displays following error:-

server is already active for 0. If this server is no longer running, remove /tmp/.X0-lock and start again.

I remove .X0-lock file. And run startx again. Then error display:-
Make sure an X server is not already running.

Please tell me the commands to run startx without restarting.


Answer : I addressed #1 in another question you asked.

#2 - If you have done a normal install of RedHat and have not purposely disabled telnet then there is likely a network device blocking your access. Examine your connectivity between the machines - how is your connection happening (is there a firewall in between)?

#3 Address is a different question.

#4 Pressing ALT-F2 does not quit the current X session; that's why it won't allow you to start another. It's still running. Press ALT-F7 I think to get back to X-Windows.

Subject : Installing Linux
Private : No

Question : Hello,
I recently bought a new computer with the OS loaded. The OS is Windows Me. I recently whent to install Linux, but I found out that my computer does not have a full version of DOS, so I could not install it. My question is, Is there a way to install Linux with my DOS I have now, or do I have to download DOS, if so, where can i find it?

Fr0g

Answer : You don't need DOS to install Linux. All you need is some free space to create disk partitions (may need a tool like Partition Magic to do this if the people who built your PC used all the available space for Windows partitions) and the bootable CD of the Linux distro you want to install. Free the space and then boot off the CD to begin the install. After the install, if you get it all right, you will have a dual-booting machine with Windows and Linux. Before you start all of this though make a DOS boot disk that you can get back in with. FOllow this procedure to make one and if you get in trouble you can issue:

fdisk /mbr

after booting from it if Linux's bootloader causes any problems.

OK - Make a boot floppy (on your or another Windows machine) as follows:

Start/Programs/MS-DOS Prompt

(put a blank floppy in the drive)

format a:

c:
cd \
sys a:
copy windows\himem.sys a:\
copy windows\smartdrv.exe a:\
copy windows\command\mscdex.exe a:\
copy windows\command\xcopy*.exe a:\
copy windows\command\format.com a:\
copy windows\command\edit.com a:\
copy windows\command\sys.com a:\

Download the following file to A:\

http://members.home.com/iqueue/idecd.sys


Now create a config.sys as follows:

edit a:\config.sys

The config.sys needs the following in it:
device=\himem.sys
device=\idecd.sys /d:cdrom001

Save the config.sys

Now edit A:\AUTOEXEC.BAT and put the following in it:

@echo off
\mscdex.exe /d:cdrom001 /l:f
\smartdrv /n c+ f 4096 4096

Save the file and exit.

Now test the disk and ensure it boots and brings the CD-ROM drive up successfully as letter F.

Jeff

Answer : Become root and do a:

ifconfig -a

This will tell you what network card you have available (ex - le0 - be aware that lo0 is the "loopback" device and is not for use).

Now issue this command:

ifconfig le0 10.11.12.13 netmask 255.255.255.0 broadcast 10.11.12.255 up

where

'10.11.12.13' is the IP address you want to give the machine

'10.11.12.255' is the broadcast address for that network

Then you may also need to perform a:

echo 10.11.12.1 > /etc/defaultrouter

which will create a defaultrouter file which contains the IP address of the machine that provides your default gateway to machines outside your LAN segment.

when i put the command "ifconfig -a", I get the following response:

loO: flags-1000898<UP, LOOPBACK, RUNNING, MULTICAST, ipV4> MTU 8232 index 1 inet 127.0.0.1 netmast ff000000

when I put the commmand"
ifconfig le0 10.11.12.13 netmask 255.255.255.0 broadcast 10.11.12.255 up ", I get the following:

ifconfig: SIOCGLIFNETMASK: le0: no such interface

I put a 3com card as well as a netgear card in. both times, i could not configure it. how do i know the interface name?




Answer : If the card was in and operational when you did the OS install it should be there. If not then reboot the machine, and press STOP-A at the banner display (before the boot really gets started). At the "ok" prompt type:

boot -r

That will force the machine to rebuild the device tree and it should then find the network card.

Subject : Home networking
Private : No

Question : I have two computers that I am trying to network together.
I am using a Linksys 4/5 port hub.
Question about the Hub does it matter what ports I use. I am currently using two of the regular ports, not the uplink or the fifth special port, I think it is for dasychaining another hub. The hub has a total of six connentions. The hub is at least 3-4 years old.

The first computer is an older one using a P90 intel motherboard with an AMD K5-200Mhz upgrade prosessor and 98Mb of ram, running W95-OSR2 using a PNP ISA NIC card (3com).

The second Computer is newwer and has a Tyan S1590S 100Mhz bus MB with a AMD K6-3 350Mhz CPU and 128Mb of ram. It has a PCI NIC card (3Com).
It is running Win98 first release.

The second CPU sees it self in NN after initial setup.
But the older CPU does not see anything in NN it gives me an Error message when I click on NN.
Note I am trying to get the network working because I am getting DSL in Feb.
and I want to share the connection between 3 to 4 computers. I have two other newwer computers running Win98 first release but I don't NIC cards in them yet.
If you need more info let me know.

Thanks, Electroman

Answer : You are correct that the uplink port is for what is called 'cascading' which means to span to another hub.

The computers appearing in the Network neighborhood is not really relevant to sharing the internet connection. That happens at a lower level. You'll obviously be using ICS on the 98SE box as the host machine for sharing the net connection, which means it will need another NIC.

If you want the machines to be able to share files on the Windows network make sure the IP address information is set correctly. Here's settings that will work:

PC #1 (95 OSR2)

IP address - 10.1.1.2
subnet mask - 255.255.255.0
default gateway - 10.1.1.1
DNS - put in entries your ISP provides you
Workgroup - Electroman

PC #2 (98 SE)

IP address - 10.1.1.1
subnet mask - 255.255.255.0
default gateway - probably left blank as ICS handles routing
DNS - put in entries your ISP provides you
Workgroup - Electroman
Install ICS and configure

Add the "Client for Microsoft Networks" on both machines. Then double-click on that item and disable the ability for the 95 machine to be the Browse Master, and enable it for the 98SE machine. This will make the 98 SE box responsbile for keeping track of what shares are available on each machine, and on populating the NN for each machine.

Question : 3 questions

1)I have a question about novell networking. How do I access the netware administrator utilities, where I can create accounts, create a tree, logins, mappings, and so on. When the novell login box comes up, it says username and passord. To access the utility what do I do? Do I type admin for username and type the company's password.

2)Plus do you have any websites or book names that will show you step by step on how do create accounts and other network stuff.

3) I hooked a computer to a network and I installed the novell software also. I also gave the computer an IP address and I did all the Tcp/IP settings. I also configured their email system which is outlook express. And it works. They are able to send and receive email. But they cannot access the internet, It gives an error http: 403 or 404 error. Do you know what may be wrong. What should I do!!

Answer : After logging in successfully you can then do a Start/Run/nwadmin

nwadmin is usually stored at:

SYS:PUBLIC/nwadmin.exe on your file server

As for help in using it:

http://www.google.com/search?q=using+nwadmin+netware+administrator+tutorial

How does the machine get to the internet? Are you behind a firewall, or more likely are you using a *proxy server* and need to setup this new machine with the proxy server's address? To check for existence of a proxy server get on one of the machines that can get to the internet, load Internet Explorer, then select Tools/Internet Options. Then under the Connections tab click on the LAN Settings button and you should find the proxy information. Replicate what you see here on the new machine.

Subject : Client Browsers Not Reaching All Pages
Private : No

Question : Hello,

I hope you can help me. I have a small SOHO network in my home, consisting of a Win2K Advanced Server machine and 2 Win98 machines. The Win2K box is using ICS to share a dedicated DSL connection to the Internet. This machine is running Norton Internet Security Firewall. The DSL bridge is attached to the same hub used by the home network.

My problem is this: The Win2K machine accesses the Internet with no problems. However, the other 2 machines can't seem to get to certain web pages, even with the firewall disabled. Here are a few of the problem pages:

http://www.maps.yahoo.com (www.yahoo.com is OK)
http://www.napster.com
http://granndgarb.com/pastpattern.shtml
http://www.renstore.com
http://www.countrywide.com

When access to these pages is attempted, the browsers seem to resolve the name, but the pages never load and finally a timeout occurs.

Before switching to DSL, this was not an issue. Any help you could provide would be greatly appreciated.

Regards,
Mark Murphy

Need More Information : Were you NATing with ICS and firewalling before getting DSL?

Have you tried accessing those pages with the firewall disabled? I use NAT myself but not ICS, and I haven't seen a real need for a firewall too, as outside machines can't initiate a connection with a machine behind the NAT - they simply can't address the machines behind the NAT.

I would test without the firewall as it may be to blame. Barring that I'd suggest you download the free trial version of what I use - Sygate (sygate.com) or WinRoute Pro (tinysoftware.com), both excellent NAT implementations.

http://members.home.net/iqueue

FUQuestion : Paul,

DSL and firewall were implemented at the same time. NAT was working fine before that, although configured manually via Win2K's NAT setup instead of using the "idiot-proof" (definitely applies to my case) ICS checkbox.

The pages in question won't load with the firewall disabled either. Firewall itself causes some problems with Napster, etc., but I'll probably be able to figure those out.

Are the NAT utilities you mentioned safe for Win2K? I had a serious problem with a similar package and had to do a complete reinstall. I'm also a little hesitant to use a third party utility because I don't know if my DSL bridge software will be compatible. Another concern is my almost complete ignorance of networking issues. I find I get in over my head VERY quickly!

Hope to hear from you soon. Thanks a million for your timely response. If you ever need advise from a seasoned software engineer, please don't hesitate to call!

Regards,
Mark Murphy

Answer : Check their web site, but I'm pretty sure that Sygate supports Win2K. IIRC I installed it to Win2K for a while but went back to NT4 for the much lower resource requirements (Win2K is a pig).

Thanks for the offer of assistance!

Answer : The remote machine must have an X-Server running on it (or be another UNIX machine). If that is the case on the remote machine:

telnet to the Sun machine

DISPLAY=x.x.x.x:0;export DISPLAY

(where x.x.x.x is the IP of the remote machine you are on)

Now just run your X app and it will display on the remote machine.

If you get an error when you run it you may need to grant the remote machine permission to execute apps from the Sun with the 'xhost' command.

xhost +

will grant any machine access (but can be a risk).

Can you pls explain to me the terminology Novell Directory Services???

Thankyou

Answer : A "directory service" is just a technology of an NOS (Network Operating System) that allows all items used by the NOS (servers, users, printers, apps, etc) to be symbolized as objects. It also allows for easy organization of these objects into a hierarchical tree structure. The primary benefits are scalability and ease of administration (far easier to admin large networks with NDS than without). An NDS network is easier on users too. Instead of them having to login separately to all the servers which contain things they need, they login once to the NDS tree and have instant access to all the objects of the network they have rights to, no matter where they are physically located.

Answer : About the sound:

Make sure you have no conflicts in your Device Manager tab of the System control panel. If there are some they will be exclamation points or red icons expanded from the list. If you have none identify what sound card (or chip) you have and get and install the latest drivers from here:

http://winfiles.cnet.com/drivers/sound.html

About the drive:

Try restarting in MS-DOS mode and see if you can access the drive from there (dir d:). If you can then Windows has issues. If not then your BIOS is likely to not have it setup properly. Enter the BIOS with DEL during boot and make sure all IDE primary and secondary devices are set to AUTO.

Answer : Please do not ask questions in private if they are not of a private nature. This is a general question, and not of an embarrassing nature. Marking it as private detracts from the value of our interaction to others as they cannot read it under any circumstance.


The only difference between a 192.168.x.x (or 10.x.x.x as it is in the same boat) address and any other is that those ranges of addresses were reserved for internal LAN use and by convention any internet router that comes across a packet destined for one of those networks will drop it. So they are considered non-routable addresses. Thus any and everyone can use them internally without fear of them not being unique as every other address muct be.

Answer : Well you can't download the same file from two places at the same time unless you name the destination files differently or you download each to a different directory. In either of these cases you're really downloading two copies of the same thing and it will take you twice as long (probably, depends on how much bandwidth you have) to do this, so you're better of starting the transfer from both and seeing which sends it faster, then cancelling the other.

Answer : I have not used it, but after looking into it I have to say the feature set looks impressive!

Very cool. This may be what you meant by "seamless ftp-ing" - this is far better than ftp - it is totally transparent to the Windows user - simply map a drive letter like K: to one of those paths on the UNIX machine and start using it in any explorer window or Windows app.

Question : Hi,
I recently completed MCSE, MCP + I and CCNA. I have been looking for a netwrok admin/engineer or support job. I worked in IT for 10 years as a
programmer analystand software release build engineer. I am preparing for the network admin interview.I do not know were to start. Could you pls tell me what type of interview questions do I expect when I go for an interview.Your advice is greatly appreciated

thanks

Answer : The questions will obviously attempt to probe your professional skills, education and experience. But the skills portion may take many forms. Some may only ask cursory questions like, "what's an IP address?" while others may ask you to take chalk to a board and explain something in more detail like "how does a subnet mask work?". Your best bet is to be generally aware of all aspects of networking and with the certifications you have I'd say you are ready for whatever they may reasonably expect you to know. Where you may come up a bit short is on the practical (experience) side since it sounds like you haven't done network administration before now. But emphasize your experience before this, and your new certifications and you shouldn't have much trouble landing a good job.

Question : hi there,

i am an entry level pc technician. my boss asked my that he wants our company to use vpn on our network. we use DHCP ip addresses we have a firewall on our network. we have a sisco router to connect to the internet. we have only 30 users.

can you please explain to me what excatly is vpn, how it works and how can we use in our network.
we have a WIN NT SERVER

Answer : VPN is Virtual Private Networking and is simply a way to communicate privately over public networks such as the internet. It utilizes encryption between the client at home or at a remote location and the server that has the resource the client wants. See here for more details on setting this up with Widows NT:

Answer : I'm afraid your file is gone. The more time that passes, and the more disk activity that takes place makes recovery less and less likely since the areas previously occupied by the file's contents have been marked as available and may have been used.

I have been a Accounting System Designer and Developer since many years but I was never into programming.
In the last 6 months I have done my Java, SQL etc and I have had no problem in grasping the concepts.
Recently I had been to Sydney and I visited a University for Computer Programming. The faculty suggested that I do some Operating System like NT, Unix etc as it will help me in getting a good job.
Please suggest which is the best OS to do which will help in boosting my career.

Thanks,

Tarun Shah

Answer : If they mean for you to study the care and feeding of an operating system both UNIX OSs and Windows are worth your time in pursuing. You just have to ask yourself a few questions:

1) Which are you more familiar with?

2) Which do you know more about?

3) Which would you *like* to know more about?

4) Which has the best/most jobs?

Once you answer those four the decision will make itself. :-)

Question : What is server-side processing? Client -Side Processing? Can you please tell me advantages, disadvantages of each one.

Answer : That really boils down to who does the work. In client-side processing the server may provide some of the necessary data, but working through the data occurs on the client.

Advantage:
Speed is limited only by the client
Server can be slower or less well-equipped

Disadvantage:
Clients may be slower than the server would be at processing the data
Makes you spend more to keep your clients up to snuff


Server-side processing is where the client makes a query of some sort and the server chews on the data and sends back the result.

Advantage:
Single processing point of failure (server)
Clients can be lesser-cost machines since they are not doing the work

Disadvantage:
Can be slower under multiple-user load
Server costs increase

Subject : subnet
Private : No

Question : hi,

if I have an IP address C class , for example 212.83.93.0, and I want to subnet this class into 15 networks.

what i did
-- the class 212.83.93.0
-- masck 255.255.255.240

what about each network out of the 15th networks.

network one:

-- the mask 255.255.240
-- the first IP address in that network 212.83.93.17
-- the second ip addr. 212.83.93.17

and so on

thank you
othman

Answer : Network - 212.83.93.0
Mask - 255.255.255.240

This means that the fourth octet looks like this:

11110000

For the purposes of subnetting you are reserving the first four bits for extending the network, and the last four for hosts.

So for example if I assign an address to a host of:

212.83.93.35

The fourth octet here (35) corresponds to this bit pattern:

00100011

If I break that up and examine the network and host pieces separately:

0010 0011

you can now see that this is the "32" subnetwork, host number "3". For any other machine to be considered to be on the same subnet as this machine the binary representation of it's address (the first four bits) must be identical to the one above. So this subnet's addresses would range from:

0010 0001

to

0010 1110 (broadcast address would be 1111 at the end)

Which translates to a range of:

33 - 46

14 hosts available (the full 16 minus the unusable "0" and "255" host addresses) in this "32" subnetwork.

So for each possible combination of the first four bits (some of which are - 16, 32, 96, 112, 128, 144, 160, 192) you can find the range of hosts by locking the first four bits and then doing what I did above to determine the range of addresses.

Question : hi,

i have two questions about windows NT servers

1. can a bdc be used as dhcp server providing dhcp services to clients.(
2. If a pdc which performs several services fails for some reason,can/will the bdc continue the dhcp server service

Answer : 1) Sure - you can put the DHCP Server service on any NT Server (PDC/BDC/member).

2) No, I don't think I've ever heard of a failover like this for DHCP. The main problem being that each would have to be serving up IP addresses for the same scope which is normally a no-no (for hopefully obvious reasons). To make this work you would need some extra piece of software that was aware of what addresses were being doled out by the primary and could keep tabs on the primary's health. Then when it goes down the secondary would step in with full knowledge of what was happening in the scope. Considering the clients will maintain their addresses (and only new address allocations will have trouble) this is probably far less of a concern that you are thinking (DHCP clients will automatically keep their existing address for 50% of the lease period then attempt a renegotiate from the same server. At 85% of the lease period they broadcast for any DHCP server).

Subject : IP Address vs Physical Address
Private : Yes

Question : Dear Expert,

I want to know what are IP Address and Physical Address? and whats the main difference ?

Thanks
Lok

Answer : Please don't make normal questions private. It makes it impossible for anyone but you or I to benefit from the interaction and that defeats part of the point of Askme.com. Others would likely be interested in this question.

Now as for your question:

A physical address is going to be a reference to a network card's (ethernet in this example) MAC address (Media Access Control). The MAC address is what ethernet uses to address a packet to a particular machine. Since ethernet has no understanding of any transport protocols like TCP/IP or IPX it must have some other means to get the packet where it belongs. The MAC address serves this purpose. MAC address information is only useful on the broadcast segment on which a packet originates and this is where other networking devices like routers come into play. They *do* undersstand transport protocols and will dig into a packet of data to see where it is bound TCP-wise and will reroute the packet if the destination is not local. A MAC address is assigned by the manufacturer of the network card and is burned permanently into the cards PROM (Programmable Read-Only Memory). Each MAC address is a series of 6 pairs (12 digits total) of hexadecimal digits like this:

00-03-6c-f6-38-00

The first three pairs uniquely identify the manufacturer and model of the card. These first 3 pairs of digits are assigned to the manufacturer for that card. Those first 6 digits will be the same for every card of this make and model. The last 6 digits are a unique number assigned to each card that ia made. This combination ensures that no two network cards (even of the same model) will ever have the same MAC address. If that ever were to occur (some NICs can have their MAC addresses changed which I think is pretty dumb myself) then havoc will surely result.

As for IP addresses I think I've kind of touched on that above in mentioning the ways in which ethernet addresses are dissimilar. But in a nutshell a TCP/IP address is a higher software layer involved with identifying machines (similar to MAC address) on a network and in getting traffic from one network to another (routing). TCP/IP is a transport protocol and carries with it it's own need to uniquely identify computers that need to talk. And since TCP/IP can be spoken on many computer types and indeed on many network types besides ethernet, TCP/IP must track the machines it connects itself. The TCP/IP address is a 32-bit long binary address that is used to ID a computer or other device.

So the difference really boils down to level at which each operates. MAC addresses operate at a lower level and are dependent on the type of physical network topology being used. TCP/IP addresses couldn't care less about what type of network they are being used on, and are a software-level address used by applications and users.

http://msn.zdnet.com/partners/msn/bandwidth/speedtest50.htm

These can vary with the traffic on the net however. The best test would be to get a tool like this:

DU Meter:
http://www.zdnet.com/downloads/stories/info/0,,000QDK,.html

Then with DU Meter active open a program like Forte's FreeAgent newsreader configured to a binary newsgroup on your ISP's news server and start downloading a large binary file. The speed you'll see here is as close as you'll get to your true bandwidth potential as all the data is coming from your ISP's local hardware, not the internet in general.

Can you tell me the relation between bit rate (Mbps) and bandwidth (Mhz).
Once I heard a webmaster said that his bandwidth is too small, instead why he doesn't say that his webpage speed (bitrate) is too small?

Several days ago I read an optical modulator specification. ( a device to convert voltage function into laser intensity function in fiber optic communication)
It has an operational bit rate of 100 Mbps and an operational bandwidth of 2 GHz.
I'm confused, what is the relation between these two variables. (bitrate and bandwidth).
Thanks

Answer : Typically you use the bps (bits per sec) number to measure the speed of a digital line, and bandwidth (a measure of the available frequencies for transmission) for analog lines. But people use them interchangably a lot so the meanings have kind of blended so that bps means literal speed and bandwidth means potential speed. As in, "I get about 100Kb to 200Kb per second transfers with my new cable modem, but I know it has a bandwidth of 2900Kbps so it should be capable of maxing out at around 350Kb per second"

Subject : Question bout Linksys router and IRC
Private : No

Question : Now, I'm an avid IRC user and the server I connect to uses Identd. I have set port forwarding to port 113 so that IRC work with the first computer on the network, but it doesn't work with the other two. I called Linksys Tech Support and the guy on the phone (who didn't seem at all interested in solving my problem) just simply said that only one computer can be configured for IRC at a time.

I'm not saying that guy is wrong, but for some reason I believe that this just doesn't make sense. Why would Linksys do something this stupid? It totally limits the router's functionality.

I wanted to know whether you know of a way to let all three computers go on a IRC server that uses Identd. The solution could either be in the Router's firmware itself or a software solution.

Do you think you can help? Please respond back ASAP with any possible suggestions. Thanks.

Answer : It appears that you can run MIRC on one of the systems, and it can answer the ident queries for all the machines on your network. Here's a conversation with the details (snagged from Usenet):

You can't change the port that is used for ident because that port
number is the one that the server will connect to, expecting to find a
valid ident server.
There are a couple of possible options though.
1) If you use mIRC as your IRC client, set the router to redirect
ident requests to one of the machines. Make sure that there is a copy
of mIRC running on that machine before attempting to connect with the
second computer, and set the ident server to be always on.
the disadvantage of this method is that the ident will be the same for
both systems, so you will appear as clones to anyone checking. This
may result in kicks and or bans from many channels.
2) Find a ident server that can give different answers depending on
wether or not the connection request is in use for this system. I
don't personally know of any such server available under Windows
though. I'm using an old 486 as my router, and I've found an ident
server that runs there that is capable of handling the ident requests
for any number of computers on my network.
You might also want to try contacting linksys to see if they have any
solutions to the problem. It's entirely possible that the problem
could be fixed with a software upgrade on the router, although I can't
say for certain because I'm not all that familiar with the linksys
router."

http://members.home.net/iqueue
Home of DOS/Windows Utilities

FUQuestion : I'm a bit confused now. All I originally did was forward port 113 (The identd port) to the computer on which mIRC works. I don't know how to redirect port requests to tell the router "Connect to 192.168.1.5 whenever you want to use Identd."

Here is an example of the port forwarding screen:

http://www.speedguide.net/reviews/linksys/forwarding.jpg

You can go here for the other parts of the router's configuration screen: http://www.speedguide.net/reviews/linksys/linksys_5.shtml

Please try to direct me as to how to do what the guy said to do. Thanks.

FUQuestion : BTW, Linksys has no clue either. :)

Answer : Just forward port 113 to the machine that will always be running MIRC (even when the *other* PC is running MIRC as a client) and *enable the identd server* on that copy of MIRC. That should be it. The remote server and the router don't need to know to send packets there since to all machines external to your network you are all coming from the same IP. Any ident request that comes to the router will be sent on to the machine you specify.

http://members.home.net/iqueue

FUQuestion : This is what I'm interpreting you saying:

"Make sure that the Port Forwarding screen has port 113 forwarded to the main computer and leave the other computers alone. Then they'll automatically connect to the main computer."

If this is what you're saying, it's wrong. The other computers don't automatically connect to the main one.

Answer : I didn't say that your internal computers would connect to the machine running MIRC. I said the *external IRC servers* would. Just put MIRC on the machine you point port 113 at and enable it's identd server. Then come back with the results when you're sure you have it configured correctly.

You never answered my question. I still don't understand what that newsgroup message means, and neither does Linksys. I was hoping you could interepret it for me and you never did - clearly.

Constructive criticism.

Answer : You just showed a successful login to IRC. Are you saying that was not from the other PC? Why bother to test from the machine running the identd server and is the destination for the port-forwarding? We already knew that worked. I assumed you would be testing from the other PC.

FUQuestion : Oh ok I see. I misread your question. hehe stupid me :)

I looked over at our whole conversation and I realize where I got confused: "The same way you directed the Linksys to your PC. Just point it to the machine that will always be running MIRC."

What does it mean when you say how I connected the Linksys to my PC? I connected by network cables...if that's what you mean.

Help me out.

Answer : I mean the same way you redirected port 113 to your PC. On the Linksys screen point port 113 to the IP address of the internal PC that will answer ident requests (IOW - the PC that will be running MIRC and have identd server running). Then do the following:

From that machine (the one handling identd requests) attempt to connect to an IRC server - it should work. We know this part works but verify it anyway.

Now go to a different PC and run MIRC without the identd server running and attempt a connect to the same IRC server and see if it works.

FUQuestion : Oh ok I see what you're saying. I tried that already and it didn't work.

Answer : OK - try these steps (includes BIOS update to Linksys):

Subject : batch files on Windows Me
Private : No

Question : I'm trying to run some batch files, that I suppose were written for Windows NT/2000 on my Windows Me machine.
When I run it, I get 'Bad Command or File name'. Is this a problem with the DOS on Me, or is it something else?

Here's one of them:
@echo off
rem
rem Set JAVA_HOME and J2EE_HOME before running this script.
rem
rem set JAVA_HOME to the path where you have Java 2 (JDK1.2) installed.
rem
rem set J2EE_HOME to the path where you have installed this package (EJB server).
rem
echo test
if not "%J2EE_HOME%" == "" goto CONT0
echo ERROR: Set J2EE_HOME before running this script.
goto END
:CONT0

if EXIST "%J2EE_HOME%\bin\setenv.bat" goto CONT1
echo ERROR: Set J2EE_HOME to the path of a valid j2sdkee.
goto END
:CONT1

call %J2EE_HOME%\bin\setenv.bat

if not "%JAVA_HOME%" == "" goto CONT2
echo ERROR: Set JAVA_HOME before running this script.
goto END
:CONT2

if EXIST "%JAVA_HOME%\bin\java.exe" goto CONT3
echo ERROR: Set JAVA_HOME to the path of a valid jdk.
goto END
:CONT3


rem @echo on
%JAVACMD% %LISTEN_OPTIONS% -Dorg.xml.sax.parser=org.xml.sax.helpers.XMLReaderAdapter -Dorg.xml.sax.driver=org.apache.crimson.parser.XMLReaderImpl -Djms.home=%JMS_HOME% -Dcom.sun.jms.service.jdbc.dbpath=%JMS_DB_PATH% -Djms.properties=%J2EE_HOME%\config\jms_service.properties -Djava.security.policy==%J2EE_HOME%\lib\security\server.policy -Djava.security.auth.login.config=%J2EE_HOME%\lib\security\login.config -Dcom.sun.enterprise.home=%J2EE_HOME% -classpath "%CPATH%" com.sun.enterprise.server.J2EEServer %1 %2

:END

Answer : A "bad command or filename" error means one of two things (with relation to your script):

1) The filename you are trying to execute does not exist

2) The filename you are trying to execute is not where your script is indicating it is (and is not in your PATH environment variable). You can check the contents of your PATH by issuing this command at a prompt:

echo %PATH%

So you need to figure out where it's occurring and then you'll know which it is. Considering about the only place you actually are executing anything is here:

%JAVACMD% %LISTEN_OPTIONS%

I'd say this is the problem. Try an:

echo %JAVACMD%

at a prompt before running the script. If it comes back with nothing that would be why you can't run the script. That variable is intended to point to the executable that provide the function you're after, and when it's empty so is the command above.

It looks like this script may rely on you having the Java SDK installed, and you don't appear to have it - you can get this from http://www.sun.com

Answer : I would say there is too much electrical disruption with more than 100 stations attached to one length of cable. 100 was an arbitrary number I'm sure but was probably found to never exceed tolerances even at the maximum distance.

Question : If i had a 2 DS-3(45 Mbps x2, i think) connections to the Internet, how many servers could I connect to those 2 connections, if each server had 100 websites on them?

Thanks.

Answer : You can connect as many as you like through it. The only variable that is undefined at this point is how much traffic each site will get so you can predict how congested your links will be. At 90Mb you would have (on average) around 850Kb of bandwidth per server (about half a T1) which should be adequate for most any kind of traffic.

Answer : I misspoke above as I thought you wanted 100 servers, not 100 websites *per* server. As mentioned above though that is a lot of bandwidth - unless you'll be streaming video or audio off these machines you can probably do at least 5-10 servers with 100 websites each (500-1000 websites) if not more.

Subject : nt 4 problem
Private : No

Question : Hi expert. here is my problem. I am trying to administer a small office network and have little knowledge of NT. all workstations have nt4 workstation and are running on nt4 server sp6 and back office small business server. these two problems may be related. one workstation has a visioneer scanner with function buttons and paperport software and there is also a keyboard with function buttons on it. When I logon as administer, everything works but when I logon as a user and restart, when the keybord software loads I get "error registry data not found" click ok and the program closes. then none of the special function keys work. For the scanner, it is software problem. again it works fine as admin but not as user. What I have tryed so far is to connect to the machine system policy editor from the server and change settings in there I changed all the settings I could think might effect this but still no go. I did notice the settings and explorer fuction now so the settings I changed must have done something. Is there any other things I could try to fix this problem short of giving the user admin privleges?
thanks, Nate

Answer : You might try find the section of the registry (use Start/run/regedit) this program uses (look for company name under HKEY_LOCAL_MACHINE/Software) under the Administrator profile and copy that whole branch to the user's section of the registry. It appears this was installed by the Administrator account and was not setup to be used by all users. The above may fix it or reinstalling and seclecting all users could fix it too.

--
Paul Doherty
http://members.home.net/iqueue
Home of DOS/Windows Utilities

FUQuestion : Would I do this on the local machine or from the server? if I am logged in as admin and go into regedit will I be able to see admin and users' branches to copy and paste? Also what do you mean by reinstalling and selecting all users, how do you do this. how can I give user accounts ability do install software on their machines. If I do and reinstall the software as user coud this work?
thanks again, Nate

Answer : You will do it on the machine the software is installed on. Yes as admin you will see the whole registry. Make sure you copy the branch to the same section of the user's area. Users can already install (most) software themselves - they just can't install it in such a way that they modify system files. I didn't say to reinstall the users - I meant to reinstall the paperport software as admin so you can see if it offered an option to make it available to all users.

FUQuestion : I tryed giving the user admin rights and reinstalled the software..still same problem. I tryed installing the software as user and it won't allow it. It says to log in as admin and reinstall. Sounds as if I may have to try the registry edit. I looked in the registry and did not see any particular sections in the HKEY_LOCAL_MACHINE/Software area that shows admins and users data. Would it be HKEY_LOCAL_MACHINE/Software/"users/admin or user" like this? or somewhere else in the registry?

Answer : That's not what I was suggesting. I suggested that you find the section in:

HKEY_LOCAL_MACHINE/Software

that dealth with you app (say it's called Stuff) and copy that branch to the users section so it will be available when a normal user logs in. Coincidentally haven't you called the app developer about this yet? This would seem to be something they would have a fix for... anyway. So the section is called:

HKEY_LOCAL_MACHINE/Software/Stuff

Use the regedt32.exe program to copy that key and then paste it into the "Default User" section under HKEY_USERS Software key in the registry. You'll use the two options "Save key" and "Restore" when copying the original "Stuff" key to a file and then pasting it into the new location. There's no guarantee the app will look for the data here but this section is intended to overlay with the system one and may do the trick.

Good luck...

Question : Hi,
I'm new to solaris 2.7 and I have a program (echo-client) that must access usr/local/lib that I would like to assign to nobody (because of the automatic start up feature). However, nobody does not have the right to access usr/local/lib and so I have to assign echo-client to a user, which I don't want to do because it means altering the main profile to ensure the program starts. Do you know of a way to assign nobody rights or another way to start this program automatically without altering the main profile?

cd /usr/local/lib

Answer : You aren't altering the nobody group, you're just *employing* it. It will exist as it has before. The only potential risk to this is if someone got 'nobody' privileges they could access whatever file or directory you gave access to in /usr/local/lib. I don't think this represents any more of a threat than any other account.

Subject : WINS

Question : we have in our LAN,our PDC, BDC and WINS server.we have also our remote users connected to our servers through routers in the way:
remote user -->router -->router -->PDC.

the problem is if we want to add a new PC from remote sites to our NT domain (NT 4.0)we can't connect to PDC or WINS server to add the PC.if we login to the user's workstation locally and ping WINS server, we get reply then we can connect the PC to the domain.
to summarize: we can't add workstations to the domain (PDC and WINS servers are in a different subnet connected through routers)unless we ping the WINS server first then add the PC to the domain.

Answer : NetBIOS (Windows) name lookups by default are broadcasts in the local segment and do not cross routers. Ensure the client machines are getting the WINS server IP address configured either manually or picked up via DHCP when their IP is assigned.

FUQuestion : you mean that there is no way for NetBios to cross routers to the WINS server in another segment?
so the solution is to provide WINS server for each segment?? is that right?
if yes how to update records between WINS servers in diferent segments?

Answer : No. To my understanding the machine will rely on broadcast to the local segment if it *doesn't* have a WINS server configured. If it has the IP of the WINS server it should be able to lookup names there. Just try configuring the WINS server when setting up one of these workstations and see if it can be added with that information set correctly.

Question : What does it mean when the computer freezes and the message that "the resources are dangerously low"?

Answer : You are using up the Windows stacks/heaps that are finite and fixed in size. No matter how much RAM you have there is a limited space for Windows to track objects on the screen such as windows, icons and widgets and if you exceed that amount you will get this message you mentioned. To make more memory available reduce the amount of systray apps you have loading at boot-time. If you have more than 3 icons in your systray that's probably too many. Some will be loading from

Start/Programs/Start Menu

Others may be in the registry at:

HKLM/Software/Microsoft/Windows/CurrentVersion/Run

Press CTRL-ALT-DEL to help you identify any others that may be cluttering your resources. You can load the ResourceMeter to watch your progress at freeing resources:

Start/Programs/Accessories/System Tools (add it from the CD from the Add/Remove control panel if missing).

Subject : oledlg.DLL file
Private : Yes

Question : When I start up my computer I get the error message c:\windows\system\oledlg.DLL file appears to be corrupt. What can I do to fix this? Thank you

Answer : You can try extracting the original file from your Windows CD.

The files are the .CAB files stored in Windows 98 under:

X:\WIN98

To find which CAB file has the file you need you can use the extract command. You'll note that if you do a 'dir /w /o *.CAB' command inside that directory that the files are grouped into series. For example the main set of files are the WIN98_21.CAB series of files. To see the files in that series and search for your file do this:

extract /a /d win98_21.cab > temp.txt

Now type:

edit temp.txt

and once inside the file press ALT-S and select "Find" and type in oledlg and press ENTER to see if the file is in that series of files. If you find it, start scrolling up until you find the name of the specific file that contains it. Once you find the series and specific file use this to extract the file:

extract /e win98_21.cab oledlg.dll

Then copy that oledlg.dll file over the original (or to C:\WINDOWS\SYSTEM if the original doesn't exist).

Once (if) you find the location then you can carry on with the steps I gave you.
