Subject : Proctocols.
Private : No

Question :
what is network proctocol and TCP/IP.

Answer : A network protocol is a "language" for computers or other devices to speak on a network. It sets down the rules by which data can be sent, and the means by which their integrity can be assured.

TCP/IP is an example of one implementation of a network protocol. Others examples: IPX/SPX, AppleTalk, NetBEUI and others.

Subject : networking career planning
Private : No

Question : Can you briefly list out the important skills that a network engineer needed in order to earn 70k annually. It means that what are the skills that company most sought for when interview an employee ? Thanks....

Answer : All network engineers will be expected to be well versed in:

topologies (how networks are physically laid out)

protocols (at a minimum how a protocol works in the real world and what it can be used for - TCP/IP being an example of one you must be aware of)

NOS - Network Operating System - be it Windows NT, UNIX, Netware or some other NOS you will need to be fluent in the terminology and skills required to effectively build, use and maintain your NOS of choice.

Troubleshooting ability - beyond the basic skillset you need to be able to think - understanding the underlying processes that may be involved and knowing where things can break is key to effectively solving the riddles with which you will be confronted. This is probably more important than all the others listed above (although they are certainly pre-requisites for this skill) as it is not a skill that can really be taught. Some people pick this skill up throughout their youth through logical thought, or debate. Others garner it from experience. And some from a mix of both.

Answer : Your best bet on the MCSE exams is:

- Hands on - can't emphasize this enough - install the OS many times, configure it twice as many as that. No substitute for this.

- Good reference books will help when you get stuck. Exam Crams look good for hitting the highlights once you know what's what.

- Exam preps - both test-based and web-based repositories.

Subject : networking
Private : No

Question : Being a network engineer or admin for so many years, what do you think the normal problem you will face during working that related to networking or in which area the most difficult one for you. Like troubleshooting or setting up network with mix servers. & so on. Thanks....

Answer : One of the biggest challenges usually comes when trying to isolate a problem or fault on a system that is part of a complex group of services. When you have multiple systems involved (network itself, firewall, internet connection, database servers, web servers, file servers, etc) that may all be required for a certain function to operate it's sometimes difficult to ascertain which piece is broken. This is where the KISS principle is best applied. Keep your systems as simple as possible to avoid troubleshooting nightmares.

Subject : Windows cabs file
Private : Yes

Question : I need to know if there is any software or any program that allow you to open, see, and edit the cab file?

Answer : I think most of the main archival utilities handle CAB files natively (WinZip). Try this one too:

http://www.cursorarts.com/ca_fw_b.html

You can also access the contents of CAB files from cmdline with extract.exe - here's an example:

extract /e file1.cab file1

would extract file1 from CAB file file1.cab

extract /a /d file1.cab >> cablist.txt

would extract the names of all files in the series of CAB files starting with file1.cab (proceeded by file1.cab, file3.cab, etc).

Subject : Sharing drives on a network...
Private : No

Question : Hello paul,

can you please tell me if two programs can share
the same network drive in the same session?
for example, if I use the following dos command
"net use S: \\computer\shared /yes" in a cobol
program, can another program use the same S drive
to share the network at the same time in a peer
to peer network under windows ME?
thanks a lot for your help...!
sammy. ;-)

***

Answer : The other program can *access* the files and directories on the "S:" drive as long as it remains mapped (at the whim of the first program, I'd expect if it cleans up after itself) but it can't *also* map the S: drive somewhere different. Perhaps each app can use their own drive so as not to step on each other's toes?

Subject : Using dos memory in a network...
Private : No

Question : Hi paul,

can you please tell me if a cobol program running
under dos in windows ME session, will use more
memory if it connects to another computer in
a peer to peer network to share a file?
(e.g., "net use s: \\computer\shared /yes").
thanks a lot for your help...!
sammy. ;-)

***

Answer : If you can run the command to map the network drive from within COBOL (as opposed to adding extenders within the COBOL language itself) you probably won't add any overhead as the network functionality is coming from Windows ME underneath. All you're doing is calling on it.

Subject : Using extenders in cobol...
Private : No

Question : Hello paul,

you mentioned in your previous answer that we
can use extenders in a cobol program to map or
connect to another computer beside using the
dos command "net use s: \\computer\shared /yes".
can you please tell me what is "extenders"? Is
it more advantageous to use extenders than the
dos command "net use" to map a drive?
thanks a lot for your help...!
sammy. ;-)

***

Answer : An extended, in my definition, would be like an include in C where you add functionality to your application by including functions not normally available. This is at an expense in code size. So if you can issue a system command like "net use" from within your COBOL app and use the drive letter that gets created then I say go that way. Keeps things simple and your code can treat the network call as a black box and not be concerned with the details of how the net connection gets mapped.

Subject : LAN info
Private : Yes

Question : My comany uses Windows 2000 for LAN. All my coworkers and me are under the same domain in my comany network. All we have some public folders to share files, printers etc. Does system administrator have access to the information:
- Who and when somebody accessed another person shared folders?
- Did he copy some files from there?
- If yes, then what files?

Does sysadmin has access to anyones PC and anyones data, except personal one, hidden under folder ...\username\....? I remember one day my sysadmin needd some files from my PC and he set up smth like permissions or smth like that as Administrator and saw all folders in my PC, I hope he had no access to my private data, hidden under ...my username\....

Thanks.

Answer : If he has logs enabled he may be able to tell who got what from whose machine, but I am going to doubt it when the transfers are not to or from the server itself.

As for the admin having access to anyone's machine that's a big yes. Assuming the local machine has had the Domain Admins (or domain Administrator account) added to the Administrators group on the local PC the admin can access any drive whether it's shared or not.

Subject : configuring NAT
Private : No

Question : hi there

i just installed a win 2000 server as a stand alone server, not a part of our NT domain controller. i want to use this pc for vpn connection. this pc has 2 nic's, 1 public and 1 private. let me explain how our network is setup.
we have an NT 4.0 server which is also our domain controller. we have a DHCP SERVER which assigns all our users dynamic ip addresses (15 users). we only have about 5 useable static ip addresses. we have a cisco 2600 series router. our private ip range is from 192.168.101.x and up.
this pc that i built is only to be used for vpn. i found out that in order for users to vpn to a private network, you need to configure NAT or something about ip forwarding. i don't know much about this subject, so if you could explain to me in a step by step proceure i would i appriciate it very much.

please reply

gabe

Answer : NAT will allow the 2000 server to have one valid address on one interface, and a non-routable address on the other (10.x.x.x, or 192.168.x.x). All the machines that wish to take advantage of the NAT need to be on the same broadcast segment (switch or hub) as the non-routable interface of the 2000 server, and point to that interface as their default gateway (in their TCP/IP properties). The 2000 server will need to have ICS enabled (Internet Connection Sharing) which is the NAT solution that comes with Windows 2000/ME/98SE.

At this point all the traffic from any of the machines that use the non-routable interface as their default gateway will appear to emanate from the valid address on the other side of the 2000 server. IOW the 2000 server is now their router and point of resource for arriving at any network other than their local segment of other non-routable machines.

Subject : port fowarding
Private : No

Question : Hey,

I was wondering if you could help me understand my options on a problem I have.

I have a network in my house with internet sharing, I want to be able to access the computer from the internet.

I know there is a way to set up port fowarding so I could have it send :21 to a computer with an FTP server running or what ever but is there a way to have it send :22 to an IP address but as port 21? What I mean is could I have 4 FTP servers running on :21 and have the server foward :21 to 192.168.1.1:21, :22 to .1.2:21, :23 to .1.3:21 ect or is this not possible?

Do I have any other options as for choosing what computer a port is fowarded to? Is there a way that I could simply choose on the ineternet, for example connect to my computer and tell it, I want :21 to go to 192.168.1.5 and then run the FTP?

What do you think?

Answer : I've only ever seen port-forwarding done to the same port internally, though I don't see why it couldn't be done. It would depend on the manufacturer implementing it so whether it's available in what you use will be up to you to determine.

As for the multiple FTPs (ports 21, 22, 23, etc) - why not just set each FTP server to run on a different port and forward those ports from your gateway? So have one FTP at the standard 21, another answering on 1024, a second on 1025, and so on.

Question :
I have two computers. One has window 2000 and their ip number is 192.168.0.1 and this

computer name is windows and Other has Red Hat 7.1 Linux and this computer name is this

computer name is linux and it has dhcp configured.
I can ping each computer with ip number not with the computer name.

How can I ping each other with computer name?

dhcp is dynamic.Each time linux terminal assigned different ip number. so I can't

assign temporary ip number in hosts file.

Thainking you!

Answer : If the machines stay on 24 hours a day they will never change addresses. In fact if you'll set the lease period on the DHCP server to a couple of weeks they won't lose their addresses unless you leave them off that long.

Other than setting up a dynamic DNS server (which would be a waste for only two machines, but if you want to I think the latest DNS server from Microsoft does this) there is no way for each machine to keep track of the other's IP-name relationship.

Subject : tcpip
Private : No

Question : hi there i need some information on TCP/IP, i hope you will be able to help me out. If there is local network in an office - intranet and also the outside connection to the internet, what are the sets of ip addresses i can use? i know the ISP provides ip addresses to access the Internet automatically, but what about internal there are set of protected ip addresses that can only be used for internal network usage. Can you tell me this sets of ip addresses ranges?
Thank you.

Answer : When the TCP/IP protocol was defined certain non-routable (so-called because any router will drop them on the internet) addresses were created to allow LANs to use them for workstations and other devices that need IP addresses but don't necessarily need to be addressed from the internet at large. The ranges defined:

10.x.x.x
192.168.x.x

Any addresses in those ranges will do fine. You will need a NAT router in order for these machines to communicate on the internet once they are using any of these addresses.

QAId : 6087183
Asker : bksims
Subject : email
Private : No

Question : Dear Paul,

I have an interesting dilemma. Our business utilized its own email server program called Mdameon. We use IMAP instead of POP3. We receive email leads for from two of our web sites that we must respond to. The response process involves Outlook Express. The incoming mail is opened and the email address provided by the lead on the form is clicked which opens the New Mail window. Dear whoever is typed into the body and a canned .txt document is then inserted. The send button is clicked which stores the mail in the outbox.

We can repeat this process and place from 10 to 20 outbound mails in the outbox. When the next inbound mail is clicked to open we get this warning:
There was an error opening this message. There is not enough memory. We click OK and this warning pops up Msimn has caused an error in MSOE.DLL. Msimn will now close. If you continue to experience problems try restarting your computer.

Outlook express can be reopened and we can continue for another 10 to 20 outbound messages until it happens again.

I cannot find anywhere on the workstation or the server that restricts the size of the outbox. We thought it was the workstation originally and replaced it with a beefier computer only to have the exact same symptoms.

Our network is run with a Windows 2000 server and the workstations run Windows ME.

I am lost, can you help?

Thanks,

Bill

Answer : Have you tried clicking the "Send/Receive" button periodically to force the messages in the Outbox to be sent?

Or you may want to enable the immmediate send feature of Outlook Express:

In the menus at:

Tools/Options/Send tab

there is a checkbox called:

Send Messages Immediately

Question : I Have Red Hat Linux 7.1. I have 810E motherboard. It display very small fonts. I use

Xconfigurator, xf86config command to change display setting. But when I install Linux

it ask about "high color(16 bit),true color (24 bit),256 color" options. Please tell me

command through which I can get "screen - area" Like Microsoft windows display setting

without Xconfigurator, xf86config command(it don't set properly)
?


Answer : I have never seen a utility like the MS Display control panel (though I'm sure one will be created before too long).

You will need to edit your XF86Config (or XF86Config-4 if using the newer X Server). The file is located at:

/etc/X11

Open the file with vi or another editor and look for a line like this:

Modes "800x600" "640x480" "1024x768" "1280x1024"

The order of these is important - the X Server will defaul to use the first one listed, so change the order to get the resolution you want first.

To change your default color depth look in the same file for a line like:

DefaultColorDepth 16

Setting this value to:

8 will get you 8-bit color (256 colors)
16 will get you 65,535 colors
24 will get you 16 million colors

Does linuxonfig support multi Os that include windows 2000 professional?
Thanks......

Answer : Yes, just install the OSs in this order:

ME
2000
Linux

Before starting decide how to layout your hard disk, like:

(20GB drive)

Primary partition (C:) (for ME/2000 OSs) of 3 GB

Extended Partition (data for ME/2000) of 12 GB - create one logical volume of the full 12 GB - it will become the D: drive.

Leave the other 5 GB unallocated. You will use it in your Linux install.

FUQuestion : so i can use the lilo in redhat to detect win me & 2000 professional ?
Will it be any conflicts between the win 2000 professional & redhat linux boot loader? Thanks...

Answer : Win 2000 will add a bootloader to choose between itself and ME.

Linux will install a bootloader to choose between itself and Windows in general.

Upon booting your machine you will have to choose between Linux and Windows. If you choose Linux you're done and into Linux you go. If you choose Windows you will then see the same 2000 menu you would have seen before you installed Linux where you will choose between ME and 2000.

If i want to use redhat to surf the internet, what type of modem i'm going to buy. Because last time i use a creative modem blaster, but it cannot detected by the redhat. Pls give me some sample modems or related websites. Thanks a lot.

Answer : You can use any modem you like *as long as you don't get a so-called "WinModem". A WinModem uses the CPU to do some of what a normal modem does for itself and thus requires OS/driver support to do its work. A real modem does not need this layer of software and is superior. Get a regular modem like a 3Com Courier V.Everything. Just tell the salesperson you want a 56k modem that is NOT a WinModem. Or print this sheet out and take it with you - they'll get the picture. :-)

Subject : gnutella network
Private : No

Question : Hi. While I was using LimeWire to get on to the gnutella network I noticed (using the bandwidth monitor that is included in the software) that many people were searching for files on my computer that were either illegal, highly offensive, or otherwise immoral. Is there a way (using _any_ client) to disallow people from searching for files on your computer. One reason I ask this is because if my little sister were to use the program and click on the MONITOR option she would be bombarded with profanity, and people searching for disgusting things.

Any ideas on how to stop people from querying my computer?

Answer : Different GNUTella-based apps have different options. I like BearShare best (if you make certain to unselect all the extra detritus it tries to install along with it) and I believe the latest version had a filter to stop this type of thing. Also in BearShare you can select to NOT share at all and to stop searches from taking place on your machine - though I expect the "monitor" would still function - if your sister turned it on she would then see the things other people are searching for (not on your computer, but on the GNUTella network in general).

Subject : connecting to the proxy server
Private : No

Question : hi,
if i have configured solaris on a machine which is on a network. How do i ping the server which is a proxy connected to the internet.
At the moment the machine with solaris is on the network, and my aim is to connect to the internet, however, first i have to make sure that i can ping to my own server, right? therfore, what do i have to configure on the machine which has solaris inorder to accomplish this. Once i can ping to the server, is there anything else i have to do to connect to the internet??

Thanks

Umar

Answer : I'm not sure if you're saying the Solaris machine you configured exists ON a proxied network, or if you're saying the Solaris machine IS the proxy. I'm going to go with what seems most likely - that the Solaris machine is ON a proxied network and you want to know how to get to the internet.

The usual thing to do is to verify normal network connectivity with ifconfig (make sure you have the correct IP address, netmask, etc) and ping commands. Once you know the network connection is live then be sure you have the correct default gateway address stored as an IP address in a single-line file called:

/etc/defaultrouter

Finally configure your client applications (web browser, ftp, etc) to use your proxy server IP and port for connectivity. Check the settings for the client you intend to use - virtually all modern clients for most protocols support the use of proxies.

Subject : solaris proxy again
Private : No

Question : hi, thanks for replying earlier.

yes you are right i am on a proxied network.

you asked me to check the ifconfig, all i get is a listing of parameters. It does not show my IP address or mask. Am i suppose to look for something specific, becuase i am new to solaris.

also i do not have a defualtrouter directory in my etc folder. I do have the following:

/etc/netmasks - which contains my network number and mask

/etc/net
/etc/netconfig
/etc/networks

also i cannot ping to my proxy server

is there anything i can do, or do you have another solution.

Thanks
Umar

Answer : You use ifconfig to configure your ethernet interface so you can get onto your LAN. Use the following command (be root to run this if you intend to change anything):

ifconfig -a

(will show something like this, depending on OS version and hardware)

lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 132.111.79.67 netmask ffffff00 broadcast 132.111.79.255
ether 8:2:20:f2:81:7f

Note that there are two devices listed here "lo0" and "hme0". The lo0 is your "loopback" device and is associated with the loopback address 127.0.0.1. It is used for testing purposes or dummy devices. The real interface on this machine is hme0. To configure hme0 from scratch to the state it is in now:

ifconfig hme0 down
ifconfig inet 132.111.79.67 netmask 255.255.255.0 broadcast 132.111.79.255 up

The interface should now be live assuming you have the right IP address, subnet mask and broadcast address. You should attempt to ping your default gateway which you should put into your /etc/defaultrouter file like this:

echo 132.11.79.1 > /etc/defaultrouter

Once you can ping the default gateway you should be in business. Reboot the machine and be sure the interface maintains it's address and then try pinging again (gateway and beyond). Then try your web browser.

Subject : connecting to the internet
Private : No

Question : hi,
i have made a defaultrouter file which contains my proxy address, however i cannot work our how to configure my browser which is netscape, and input the proxy address and port number. However this was done at installation.
Can you please tell what the problem/solution is?

Also the hidden file in solaris i.e. /.netscape had a file called locindep.dat, whcih contained my proxy address under session id, so i added my address under client id, and was then able to ping to my proxy. Is this correct what i done?

Also what does this mean: $SOCK_NS, that this should be pointing to the appropriate name server, as this is what comes when i click the browser icon. It tells me that it is an environment variable, can you please tell me how i can manipulate this.

Thanks

Answer : The defaultrouter does not get the proxy address it gets your default gateway, which is usually a router port on your LAN. For example if your IP/subnet mask are:

123.32.31.21 255.255.255.0

your default gateway will usually be:

123.32.31.1

It's simply the IP address of the device that can take your packets to networks other than your own. If the proxy server IS your default gateway then that's OK to have it in there.

Netscape has browser proxy settings under Edit/Preferences/Advanced. Poke around and you'll find it.

I'm not sure what the hidden file you're talking about is, or what you did to it. You can set the environment variable it refers to in your .profile (in your home directory) like this:

SOCK_NS=123.12.13.14

OR

SET SOCK_NS=123.12.13.14

(which you use depends on the command shell you use)

SOCK in this case may refer to your proxy server as they are often referred to as "SOCKS" servers. You may want your proxy server address in that variable.

also do i have set my ISP domain name or IP address anywhere?

Answer : No, the proxy needs nothing done to it. You just need to know the IP address of the proxy and the port across which it will handle traffic.

Netscape has the proxy settings at:

Edit/Preferences/Advanced/Proxies

Click the "Manual proxy configuration" then click View and put in your proxy info there.

also does my proxy server need to be down if i am to configure the proxy address and port in my netscape browser, Because i know there should be a proxy option under the advance setting, but i cant see it when i click advance.

also after all of the above the message i get on netscape is saying that my server is down or it could be busy, which it isn't, what else could be the problem?

and do you know of any good solaris books/web sites.

Thanks

Answer : Yes I said the name of the ethernet interface would be different for other models of Suns.

Check what shell you're using:

cat /etc/passwd | grep yourusername

and you will see a line like this:

ped:x:108:1::/export/home/ped:/usr/bin/ksh

At the end is the shell being used, in my case /usr/bin/ksh (Korn shell).

If you are not using ksh or sh I would suggest you become root and edit /etc/passwd and change yours to ksh.

Then vi a new file if you must called .profile in your home directory and out your environment variables there.

Question : hi,

we have set up a domain on windows 2000, that connects, through a proxy server, to the internet. We have configured our solaris box to connect to the internet through the domain controller. Although we can ping the domain controller and the proxy server, when we try to access the internet we get the error message, "page under construction", whatever site we try to access, whereas we can connect from the domain controller with no problems.
We have configured the resolv.conf to point to the domain controller(windows) and enabled DNS through copying the nsswitch file.
Please advise.


please can you also explain why solaris internet connection works only on domains and not workgroups(windows)?

thanks.

Need More Information : Is the proxy software *on* the Windows 2000 machine or are you saying the Windows 2000 machine uses the same proxy (on a different machine) that you want the Solaris box to use?

I'm thinking the latter, so you will need the resolv.conf on Solaris pointing to the machine that is your actual DNS server, not necessarily the 2000 box (unless it IS your DNS server). Once you set the DNS server test it with an nslookup command:

nslookup
(should report what server it is using - be sure it corresponds to the IP of your DNS)

hostname (ENTER)
(should retrieve an IP for a machine called 'hostname')

exit (ENTER)

OK now your DNS works. Now you simply need to point your browser or other network client to the proxy server IP and port so your traffic can leave your site. In Netscape, for example, those settings are under Edit/Preferences/Advanced/Proxies.

Here are some clients that will help make proxy usage a bit more transparent:

http://www.socks.nec.com
http://www.inet.no/dante

As for your last question I'm not sure what you mean by Solaris internet connection working with domains and not workgroups - do you mean file-sharing between Windows and Solaris machines? If so try this app for excellent sharing:

FUQuestion : HI PAul

Thanks for your help - am now on the net.

Am now trying to install Samba; I installed the Companion CD that came with the Solaris pack but the samba files do not seem to be in - (no usr/local file exists). I have a feeling they are zipped in the opt/WINnfs.zip file - is that correct? If so how do I unzip them? I tried rightclicking and choosing unzip from the CDE but it just opens an unzip window and then gives some strange messages about replacing files then freezes...

The suffix is definitely .zip. not gz or Z or tar...

What do you think? Am I missing an easy solution or shall I just download it off the web with my hardwon Internet connection and go from there...?

Thanks in advance,

Dan.

Answer : You can get Samba from samba.org, too, although I wouldn't guess that WINnfs.zip had Samba in it - sounds more like an NFS gateway or something.

As for .zip files I think you need a utility called 'unzip', which you should already have.

Question : Again I need your help.
I need to transfer some files between my two computers. One with a NetEasy d-link drn-32tx PCI card and one with a 3Com Etherlink III isa wich is not PCI. The salesman only had a PC-hub UTP cable. Could that work?

The problem is that I can't get contact. I have logged on both computers and it is possible to find the machine I am searching on, but not the other. What protocols should I have, how do I figgure out what IP to ping and how do I get conection?

I have a Zero modem cable (directly translated from Norwegian) for the LPT port, but I can't get connection there either. How do I configgure this?

Thanks

Answer : The ethernet cable you have is a straight through pin cable intended to connect a PC to a hub. This will only work if you have two cables (one for each PC) and an actual hub. To hook the systems directly together you need to switch pins 1&2 and 3&6 (so that pin 1 goes to pin 3 at the other end and so on). Or you can buy one already made - they are commonly called "crossover" cables.

As for your other cable I expect you mean a null modem serial cable (for a COM port, not an LPT). This will work too - just use Windows Direct Cable Connection to setup the connection between the machines once the cable is installed. You can add it from Start/Settings/Control Panel/Add-Remove Programs/Windows Setup/Communications tab in Windows 98.

The easiest way to do it is with a cable router like Linksys or DLink offer. Each machine will need an ethernet card and cable. The routers can be found here:

Question : hi!
i want to share a cable modem connection with two computers. Someone told me i needed to get a hub. So, i got somthing that was called DE-805TP 5-port Hubby from D-link. I tried connecting it to my cable modem and computers but it does not seem to work. i don't really know what to do with it. Have i gotten the wrong product? How do i set up everything properly?

ANY help at all will be apprieciated!!!!
Thanks!!!

P.S I am an idiot at computers. Please explain in layman's terms. Thanks a lot!!!!!

Answer : Unless you have paid for multiple addresses from your cable provider a hub is not what you need. The problem is this. Your cable modem will have an IP address (network address) assigned to it by your ISP. Your PCs will get addresses you give them. Since you cannot legitimately give your PCs addresses on the same section of addresses as your cable modem they will not communicate with each other over a hub, as all machines on a hub must be in the same "broadcast domain". This means they must share the network portion of their IP address in common for them to communicate.

To be able to use more than one machine on your cable you need to do one of two things:

INSTALL ICS

1) Get a second network card for the machine that is going to be hooked to the cable modem. The connections will look like this:

Internet - Cable Modem - (NIC #1 - PC1 - NIC #2) - Hub - PC2

That is, the connection will come from the internet, into the cable modem and from the cable modem to the "external" (faces the internet) NIC (Network Interface Card - that's your ethernet card). That is the internet side of things. The same PC has a second NIC that connects to the hub. Another hub port is taken by the second PC.

The IP address for the cable modem is an internet routable address, meaning that anyone on the internet can use that address to get traffic to that machine. The internal NIC on PC1 *and* the NIC on PC2 must use non-routable addresses. When the internet was laid out, a few ranges were left open as non-routable addresses people could use for internal machines that didn't need direct internet access. This saved people from having to get internet addresses for all their machines and saved a lot of addresses for use on the internet. A couple of those ranges are:

10.x.x.x
192.168.0.0

You can use either of these ranges (with numbers from 1-254 where the 'x's are) for the internal machines. So with this information this might be your IP addresses on your network:


PC1 NIC1 - 24.1.2.3 (internet address from the cable modem)
PC1 NIC2 - 192.168.1.1
PC2 NIC - 192.168.1.2

PC2's NIC needs it's default gateway set to the IP address of PC1's internal NIC (192.168.1.1). The only other thing to do to enable the sharing of the internet connection is to install ICS (Internet Connection Sharing) on PC1 (assuming PC1 runs 98SE, Millenium, or Windows 2000).

BUY A HARDWARE ROUTER

2) The far easier method than #1 above is to return the hub and buy a "cable router" from DLink or Linksys. These devices can be bought with 4-port switches (like a hub, but better) and will connect both PCs to the cable modem and handle the sharing of internet connection. Get them and more info on them here:

http://www.us.buy.com/retail/searchresults.asp?qu=cable+router&loc=273

Be sure to get one that has more than 1 port so your machines can all work with it.

Question : Hello paul,

i was told that windows 2000 does not allow some
DOS programs to run in its environment because,
they tend to try direct access for the hardware.
can you please tell me what is hardware direct
access, and give me an example?
thanks a lot for your help...!
sammy. ;-)

***

Answer : A perfect example is a DOS game like DOOM or DOOM2. Those games directly accessed the hardware of the video and sound cards they ran on, instead of doing what all Windows do these days, which is to access hardware functions *by way of* APIs (Application Programming Interfaces) which allow the OS to protect itself from rogue programs that may cause system instabilities from direct access, as well as free developers from having to know the innards of the hardware on the market. Microsoft's DirectX and it's technologies are an example of this type of API. When a developer wants to generate a sound or draw an image they do so by means of the functions provided within the API. Then the API deals with the hardware driver which translates the desired function into the specific manipulations the hardware will need to produce the finished result.

Subject : I am not seen on Internet Games
Private : No

Question : I had ADSL modem on my W98 PC and everyting was ok but then I made me Server and put modem in there and I had good Internet access through this Server from my W98 PC but when I create games on multiplayer on Internet my game is not seen by other players and when I join other games and other players try to get my IP address they only get 0.0.0.0 + Socket number.

P.S.
I read one question on your web and the answer to this question:

jjabbott@..., a user from techies.com, asked this question on 10/11/2000:
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.

is(I think) that Guest user account on NT is disabled or with no rights and he don't need netbuei protocol for this purpose.

Regards
Thorvaldur

Answer : Your problem stems from your using the server as your gateway to the internet. You didn't say, but I expect you're using ICS (Internet Connection Sharing) on the server and this uses NAT to allow the one IP address you get with your DSL to be used by all your machines inside your network. The problem is exactly that - the *server* now has the legitimate IP address of your DSL modem, not your PC that you're hosting games from, and the NAT software is designed to (by default) drop packets that come in that are not a reponse to an outgoing request from one of your machines. You will need to add support for gaming to the server (search for "ICS NAT games" or similar on web search engines for help in modifying ICS - I don't use it) OR upgrade to a better NAT solution. One of the best is Sygate, which is simple to install (now that you understand waht is occurring) and has support for every game I've ever tried.

FUQuestion : Thank you for exelant andswer Paul.
You were right about ICS I used it.
I tried this Sygate and it does not seem to solve this problem. But now I know why this occour I can try to find soloution. Strange I can't tune this in ICS or NAT. Do you think this is any better in Win 2000 Server?

Answer : I don't know of any differences, but as I say, I'm not really familiar with ICS since I use Sygate. Try this resource - this looks like exactly the type of thing you'll need:

FUQuestion : At the end I found out a way to solve this with your help Paul and tank you very much. This is the soloution to the problem:
In ICS(Win 2000) there is possibility to bypass this packet dropp(incoming requests(for safety reasons)) by entering the port number(settings tab) and the IP address of the PC who is to get this data. Make static address for client NOT! DHCP(optain IP address automaticly) and all is cool.

Thanks!

Subject : Sharing a cable modem using a hub
Private : No

Question : Hi!
I would like to share my cable modem using a hub. i got connected everything together (computers to hub; hub to cable modem). However, it seems that I can only use the internet connection on either one computer at a time, and not both together.
How can i set up everything properly with as little complication as possible?

Please give detailed instructions
Thanks a lot!!!

Answer : You will need more than a hub unless you've paid for multiple IP addresses from your ISP. You will either need to setup one of the PCs as a gateway (using ICS in Windows 98SE/ME/Win2k/XP) OR buy a cheap hardware cable router like the LinkSys or DLink, available here:

http://www.us.buy.com/retail/searchresults.asp?qu=cable+router&loc=273

In both cases above you are making the one valid IP address be shared with all the machines internal to your LAN.

Question : What is the differnece between DDNS and DNS?

Answer : DDNS is just a DNS server that can receive dynamic updates about the IP to name relationship of machines it answers for. This is most commonly associated with DHCP (Dynamic Host Configuration Protocol) where workstations get an IP address delivered automatically. In a DDNS environment the DHCP server would contact the DDNS server with the IP/hostname of the machines it gives addresses to, meaning even those machines that get a new address often will be resolvable in DNS.

It is greyed out. When I had a p2p network with win98se it worked fine (except the ink level thing I only got that to show up on the host weather it was win98 or 2K). Any ideas?

Answer : The only thing you can tweak with regard to a printer is it's drivers. I would just ensure that you have the latest for the USB device and perhaps contact Epson (or scour the forums) for information.

Answer : I'm not so sure about the differences in pay, but I'd say you'll be OK financially with either one. To find out which you prefer take some classes (one or two) in each and see which one appeals the most. There's no substitute for trying these things out - it's not reallt practical to try to plan for which you'll like in the absence of real experience. Then you can choose with confidence.

Question : Asking about university network

I am a first-year student and have a laptop. I am staying at the university hall of residence. Of course, I need to have my laptop connected to the internet for my study and leisure activities. Now I have two choices:

1. Connecting to my university network.

2. Using the free or low-price services by such companies as AOL

As a student, I am interested in downloading MP3s (from Napster, etc.), but I dont know if using my university network allows me to do that. My university technical page is :

http://www.nottingham.ac.uk/acs/sns/

Could you please check it for me and tell me whether, under this kind of connection, I can use Napster to download MP3s?

My sincere thanks,

Answer : I'd say you'd be skirting on thin ice there. It's unlikely they will come after you for it, but it says no file-sharing:

"4.3 You must not configure anything you attach to the network to provide any network service of any sort across the network (for example WWW servers, Unix emulating Servers, Windows NT Servers, FTP servers, BOOTP servers, DHCP servers, Windows file and printer sharing etc.)"

If you can I'd get your own connection if it's a fast enough one to compete with the University's network.

The battery you refer to just provides power to keep your BIOS settings stored in the CMOS memory and would have nothing to do with rebooting.

We tried changing the switch, but we still had the same problems. But any pc that is connected to the router has excellent speed. Can you please suggest on what could be the problem

Please reply,

Gabe

Answer : If they're both actually *switches* and not *hubs* you shouldn't really see any speed increase from your cascading of them.

Have you tried plugging no machines into the cable router and all into the extra hub to see how that goes? That would give some more information to go on. Also run some quantifiable speed tests (transfer between PCs that are on either switch, and tests like at dslreports.com for speed from the internet both on the cable switch and on the secondary).

we have a cable modem, a patch cable goes out of it and to the WAN port on the router. I have 3 pc's connected on that router. i took another patch cable and form the UPLINK port on the router, i connected it to an available port on the SWITCH not a HUB. all the pc's that are connected to the ROUTER have fast connection, and all the pc's that are connected to the SWITCH have slow connection.
and no i did not try not connecting anything to the router, but i can do that when i go back to the office on monday, but what would that prove?

Answer : You need to isolate the problem and that is the purpose of testing speeds alone on the switch. Get some hard data from machines on the router's switch ports and on the cascaded switch's ports from dslreports.com to see how marked a difference you're seeing.

I also have other work and business files that I would like to keep up-to-date, but unless I copy them to disk and physically move them, Im at a loss.

Anyway, is networking the answer? How complicated is it? My desktop system runs on Windows 98 and the notebook on Windows 2000. I do plan to upgrade both to the XP sometime soon. Also, the desktop to is connected to a router and communicates via a DSL line.

Any thoughts or help would be appreciated.

Thank you

Answer : Yes, networking is the best answer. Once connected you can even have only one version of the files, stored on just one machine, with the other machine having transparent access to the files via sharing across the network. Open the files from either machine and save the changes there and both will be accessing the latest version (and saving you disk space by not duplicating the files on both machines).

If your DSL router has more ports you can simply plug the second machine into it - then both machines can talk and both can get on the internet. If you have a router with just one port for PCs, get yourself an ethernet switch with 4 or more ports. Then plug the DSL router into one port (may need to use the uplink port) and the PCs into the other ports.

Subject : hub and switch
Private : No

Question : Dear Sir/Madam,
Can you please tell me if I have a say 16 ports hub and 16 ports switch what will be bandwidth on each port for hub and switch?
I am facing this question in every interview.
Please give a short explanation aswell.
Thanks in advance.
Prithwiraj

Answer : It's quite simple, so chin up and prepare to ace your next interview!

Hubs come in generally two speed - 10 Mb and 100Mb

Switches also come in those speeds.

Hubs, however SHARE that one bandwidth lmit with ALL ports. So a 16-port hub would have, say 100Mb of bandwidth to share amongst all 16 ports. So at best each person plugged into a port would get 1/16 of 100Mb (6.25 Mb). But in actuality they'll get even less if there is much traffic occurring due to a hub's other limitation - collisions. Since every packet that enters a hub is ALSO echoed out in real-time to all other ports (since a hub is ignorant of what machines lie where) there is a possibility for collisions. Collisions are where two machines transmit at the same time (both having heard "silence" on the line beforehand and thinking it was safe to "speak" - this is the "carrier sense" of CSMA/CD (Carrier Sense, Multiple Access with Collision Detect). A collision loses bandwidth because now both machines detect the collision and will now have to retransmit their packets. Since there is no timing device they wait a random interval before attempting to send again. I think you can see that with two machines this isn't so bad, but with 16 at once collisions can get pretty high.

Now contrast all of that with a switch. One of the principal differences between a switch and a hub is that a switch isolates each port into it's own broadcast domain so collisions cannot occur with other machines (most times they are also full-duplex, meaning you can send and receive at the same time). This alone speeds things up considerably. But a switch has another benefit - in addition to isolating machines it also provides dedicated bandwidth to each port, so a 100Mb 16-port switch will have 16 ports of 100Mb of dedicated bandwidth each for a total of 1.6 Gb of bandwidth! When you hear people refer to "backplane bandwidth" that is the amount of speed the internals of the switch can deal with (i.e. "all ports active at once").

So there you have it, a hub shares all of it's bandwidth, while a switch has dedicated speed of the full amount for each port. A hub provides no insulation for traffic from each port, which results in collisions that eat at it's already limited bandwidth, while switches isolate each port for protection fro collisions. Switches, therefore, are hip to MAC addresses (the addresses burned into Ethernet cards) since it will not replicate every packet coming in to every other machine on the network, only to the machine it is bound for. This means that when a new machine is introduced to a switch the switch now knows that MAC XXXXXXXX is on port 12 and any Ethernet traffic bound for that MAC address is sent there only, rather than the shotgun approach of a hub where every machine hears every broadcast.

I hope this has helped your understanding of the differences between hubs and switches.

I don't really need to put the pages 'out there' , I just want the web pages to be accessible to a group of networked windows boxes in the building.(that have internet connections) The web application itself is just related to the company's information, so it is irrelevant to anyone outside the building , and it would be preferable that it was not available beyond that region.

I realize this is a big question, but what need to know is:

-can I just serve up pages to a local area network of windows boxes?
-are you aware of any links that would give me advice on how to install all of this and get it running?
-How difficult would this be?
-what kind of hardware would I need, that I may not already have?

Thanks so much,

sara

Answer : You're right that most if not all of that functionality is available with most Linux distributions.

To avoid anyone outside obtaining information from the machine you can use the file /etc/hosts.allow and /etc/hosts.deny to mold what addresses will be allowed in or not.

This should not be very difficult to get done.

Any PC with enough disk space for your needs plus about 2GB for the operating system should be fine - I'd suggest a Pentium 2 or better and at least 64MB of RAM.

Question : Hi:

My daughter downloaded a program that seems to have add a .VBS extension to all my JPEG files.

How can I change them back and prevent them from being changed on rebooting which seems to happen.

I use Windows 98.

Answer : You are probably infected with a computer virus. VBS is Visual Basic Script and is an executable type used by viruses to get themselves run by unsuspecting users.

Here is one of the variants you may have (usually brought on by executing an attachment that appears to be a JPG (image) of a nude woman ;-)

Question :
I want to create a vedio file. I have JVC digital Camera with software that allow me to import only pictures.
Can you tell me how i can import vedio from the camera to my PC and enjoy watch it. What i have to do ?

Thanks

Answer : If the camera didn't come with video editing software you may need to go out and get one. Also you will likely need (check your manual) a Firewire (IEEE 1394) interface to be able to connect the camera for the video download. If you need a new soundcard you can get a "free" Firewire interface with a new Creative Labs Audigy soundcard as they have one built-in.

Question : Windows NT v4.0 and 2000 Network

Log files are created by an application that I use.

Everyday, they are different and they have different dates.

We store them on the server as such:

error_20011126.log
error_20011127.log
error_20011128.log
error_20011129.log

Using Linux, it is easy to set up an alias that can be used to view the latest file created.

I made a batch file that I use to edit the files. It is very simple (using the VI editor from Unix):

vi c:\winnt\logfiles\error_20011129.log

I run it using errorlog.bat

Tomorrow, if I want to edit the error_20011130.log file, I will have to either modify the batch file or make a new one (which isn't worth it).

I want a batch file that when run will edit the error_*date*.log file (pertaining to the current date).

In Unix, this is possible, as I can do it using this command:

vi /pc/home/log/error_20`date +"%y%m%d"`.log'

How can I do the same thing in NT?

Can you please give me a brief example of how I could use this to run the same batch file everyday, but get access to the latest log file?

Thanks!

Answer : You can use the 'at' command to schedule the BAT file to run daily (ensure it runs after the one that creates the log files).

Our BAT file would be along these lines, assuming you stay consistent with your naming convention (error_20011126.log, representing the log file created on Nov 26, 2001):

@echo off
REM first thing is to invoke DateSet.exe so it can grab today's date and populate our variables
c:\winnt\system32\dateset.exe
call c:\dateset.bat

REM now we'll change to our drive that has our log files...
d:
cd \logfiles

REM ...and edit today's log

FUQuestion : Ok. Sorry to bother you again.

I need one more thing.

Where do I get dateset.bat?

I have the dateset.exe from your site. But where does this come into play:

call c:\dateset.bat

The batch file isn't working, as it is editing the error_.log file.

Please advice.

Thanks!

Answer : Thanks for alerting me to this - I had the old version of DateSet on the website - I put the newest version up so grab it again and overwrite the other one. Also I forgot I didn't have the BAT file DateSet creates named the same (to avoid confusion) - it's called C:\mydate.bat, so the BAT file above only needs that one line changed and will look like this:

@echo off
REM first thing is to invoke DateSet.exe so it can grab today's date and populate our variables
c:\winnt\system32\dateset.exe
call c:\mydate.bat

FUQuestion : I hope I am not bothering you so much.

Here is what I did.

1) I put dateset.exe in the C:\Winnt\System32 directory.

2) I made a batch file called log.bat. Inside I put the following:

@echo off
c:\winnt\system32\dateset.exe
call c:\dateset.bat

d:
cd d:\app\program\log

vi error_%YEAR%%MONTH%%DAY%.log

3) I run log.bat

THE RESULT

It edits the error_.log file.

Am I doing something wrong?

Answer : Yes, you made a mistake. If you read my last post where I corrected my oversight (the naming of the BAT file I create from DateSet.exe) it's called "mydate.bat" instead of "dateset.bat". Just open your C:\ drive and you will see the file mydate.bat in there right now. So your line in your BAT file that appears as:

call c:\dateset.bat

should be like this:

call c:\mydate.bat

That's it and it will work... (also dependent on your having a "vi" command - since that is not part of Windows but UNIX (Windows uses "edit").

FUQuestion : It works. You are a genius.

Is there a way where I can move where the mydate.bat is located (as I'd prefer not to have it in the C:\ Root)?

Thanks for all your help.

Neapolitan

Answer : You're welcome!

mydate.bat will always be created in C:\ - I did that because it's the only drive letter I can be sure will be on any system it runs on. If you don't like it there you can move it or delete it when you're done with it, running DateSet.exe any time later will give you a new copy with the current time/date info. So something like this would clean up:

@echo off
REM first thing is to invoke DateSet.exe so it can grab today's date and populate our variables
c:\winnt\system32\dateset.exe
call c:\mydate.bat
del c:\mydate.bat

REM now we'll change to our drive that has our log files...
d:
cd \logfiles

REM ...and edit today's log
edit error_%YEAR%%MONTH%%DAY%.log


By adding the "del c:\mydate.bat" I get rid of it immediately after it was made, without hurting my needs at all (since the variables created by mydate.bat still exist until my BAT file stops running).

Best Regards,
Paul

Question : Hi!

I am currently sharing a cable modem using internet connection sharing. I would like to know if it is possible to share the modem with my mac(ibook) using ICS as well.

If so how dhould i go about doing it, if not, is there any other way to do this.

Thanks a lot

Please give detailed instructions i am an idiot at computers.

Answer : Yes you can share your internet connection with any type of machine, as long as that machine speaks the TCP/IP protocol. Assuming you're using the 192.168.x.x network just assign your Mac an IP address in the same range as your PCs that are also behind the ICS machine. For example if your PC running ICS has it's internal interface (to the switch where your PCs all plug into) assigned address:

192.168.1.1

then give your internal PCs and Mac addresses like:

192.168.1.2
192.168.1.3

and so on. In all cases (PCs and Macs) for machines that have to travel through the ICS machine assign the default gateway to be the IP address of the internal interface of the ICS machine - 192.168.1.1

The only other setting you'll need on all PCs is the DNS servers you use - those will have come from your ISP's documentation.

Answer : Well if you're assuming all things (like instruction sets, and cache sizes/speeds) are equal it would be like this:

8 bit to 32 bit = 4 times increase
250k to 2 million = 8 times increase

4x8 = 32 times as fast, all things being equal (which rarely they are). The systems in question would likely be even further apart than that.

Need More Information : What is this "Main gallery"?

Where on your hard disk is the file, and in what way(s) have you tried to delete it? What happens when you try (error messaages, etc)?

FUQuestion : Ok. I have this file in my video file. I storaged it into main gallery, which is a folder that came with my PC camera program. When I recorded it, it went straight to Main Gallery. So when I look for it and I find it, I try to delete it but right clicking on it, but nothing happens.

Answer : It sounds like you are trying to delete it from the Gallery instead of from the actual file system. Try doing a search in Windows with Start/Find(or Search in Win2K)/Files or Folders and type in the beginning of the filename. For a video file named "Video from Paris" you might try typing just:

paris

and be sure to start the search from the root of C: (C:\) and search all subfolders. It will take a while but when you're done you should find all files with "paris" in the name anywhere and you can delete them from there.

i am using internet connection sharing to share a cable modem. my two computers however can join each others games.

thanks a lot

Answer : Your problem stems from the fact that your IP address is not the one that people see on the internet. The machine that is running ICS is the one with two network connections - one to the internet with the real IP address, and the other that connects that machine to the internal network in your house and has the non-routable addresses. To host games internally with ICS is probably not possible as I don't believe ICS supports the port-forwarding needed, or support the concept of a DMZ. Your best bet is to obtain a copy of Sygate from http://www.sybergen.com and use it in place of ICS. Uninstall ICS and install Sygate (in server mode, no client is needed on the other machines) and you should be working fine for all games.

Subject : linksys router
Private : No

Question : Hello. I have a single SBC DSL connection at my office with one static IP address. I have the computers networked together using a standard linksys 4 port 10/100 hub, and would like to be able to share my interenet connection. I know i will have to do this with a router as I only have one static ip address. I am looking at the Linksys Etherfast Cable/DSL router. However, I am not sure if you plug the router into the hub, or just get rid of the hub and use the router as the hub. Should I connect the computers directly to a router, that connects to the cable modem, or should i connect the computers to the hub and plug the router into the hub. I do not need any file-sharing or printer sharing capabilities, only the ability to share a single ip address. In addition, does the hub come with software to configure it as a DHCP server, if so, how does your computer communicate with the router to configure itself, through the ethernet, or is their a direct computer to router connection (i.e. usb). Thank you so much for your help.

Thomas

Answer : You can do it either way, depending on the router you buy. Some routers have only one Ethernet port, meaning they will plug into the same switch as the PCs they serve. Some have additional ports and can act as the switch, removing the need for a switch. Since you already have a switch you may save a few bucks by going with the single-port model, although I would probably spring for the 4-port or more model as they are easier to resell and have more flexibility.

Answer : Buy yourself a 4-port Ethernet switch from your local computer store. Also get two Ethernet cables, one for each machine. Plug them both into the switch, and assign each machine an IP address as follows:

Machine 1

IP - 10.0.0.1
Subnet Mask - 255.255.255.0

Answer : Also make sure that each machine is a member of the same workgroup. It doesn't matter what you call it but make sure they both have the same thing. Then be sure and click "File and Printer sharing" button in 98 to enable the ability to share files and printers. You may have to do something similar in XP but I don't believe I had to do it (but I use a domain so check and see).

Now you can right-click on any drive or folder and select Sharing and assign a password for accessing it from the other machine.

Answer : It sounds like you have two different problems. One is getting the routing for the internet happening, The other is getting the machines to work in a domain/active directory environment. Work on one at a time. I suggest you hook all three to the switch ports (including the internal NIC on the server/router), assign each a unique private IP in the 10.0.0.x range (10.0.0.1, 10.0.0.2, etc), and then ensure that one is a PDC or AD controller and get the others joined to it. Once that is done then ensure the default gateway for the non-router machines is set to the 10.0.0.x address you used for the internal NIC on the router box and if your routing is setup correctly they will be able to hit the net. Test first from the server that is the router to be sure IT can hit the net before you expect the others to be able to.

Question : I would like to learn how to create a proxy server. Do you have any advice ?

Answer : Put two network cards in a machine, install your favorite Microsoft OS on it, and then install one of these:

http://download.cnet.com/downloads/1,10150,0-10001-103-0-1-7,00.html?tag=srch&qt=proxy+server&cn=&ca=10001

One network card (or modem) will be plugged into your internet connection, and the other will plug into a hubor switch that your client machines also plug into.

Subject : Design a routing protocol
Private : Yes

Question : Dear pauldoherty,

Hi! I've learnt something about routing protocol recently. My concept about it is still very vauge. I still can't understand it very well.

I have the following questions:
I have an assignment about designing a routing protocol for a customer building his own packet-switched network.

i)What kinds of things that I should take into considerations for designing the routing protocol?

ii)How can I implement the routing protocol?

iii)What do you think about the questions that I should ask to the customer?

Could you suggest any good sites for reference?

Thank you for your help!

Regards
TYK

Answer : Well I'm not all that into routing, but I can tell you some of the things that come to mind if you were designing your own:

1) Does it need to be resilient to bad line conditions? i.e. can it recover if part of it's messages are garbled?

2) Does it need to be secure? Is any form of encryption of the routing messages needed?

3) Does it need to auto-update for network changes, or will all routes be hard-coded by route administrators?

Once the customer answers those questions you could probably get started.

This site appears to have some decent info on the subject:

Answer : Install network (ethernet) cards in both machines. In the machine with the modem connection enable ICS (Internet Connection Sharing) - you will need to be running Windows 98 SE, Windows Millenium, or Windows 2000/XP for ICS to be available. Now get an ethernet switch at your local store and plug both PCs ethernet cards into it. Assign each machine an IP address as follows:

PC #1 (has the modem)

IP - 10.0.0.1
subnet mask - 255.255.255.0
DNS - put in the DNS servers your ISP gave you

PC #2

IP - 10.0.0.2
subnet mask - 255.255.255.0
default gateway - 10.0.0.1
DNS - same info as the machine above

Now both machines will be on the internet...

Subject : Smurf
Private : No

Question : Dear Paul,

What is a smurf attack and is it the same as a ping bomb. How can I prevent it in my network?

Thanks, Bill

Answer : A ping bomb or "flood" is simply attempting to overwhelm a remote system with a series of ping requests. A "smurf" ping attack involves changing the reply address (the one that should be the attacker's IP address) to that of an intended victim. This way the attacker can send hundreds or thousands of these requests to many systems, and all of their replies will actually be routed to the victim's network/machine, which can flood their connection with traffic, effectively shutting them down.

How to stop the attacks:

(taken from http://www.pentics.net/denial-of-service/white-papers/smurf.cgi)

"HOW TO KEEP YOUR SITE FROM BEING THE SOURCE
PERPETRATORS USE TO ATTACK VICTIMS:

The perpetrators of these attacks rely on the ability to source spoofed
packets to the "amplifiers" in order to generate the traffic which causes
the denial of service.

In order to stop this, all networks should perform filtering either at the
edge of the network where customers connect (access layer) or at the edge
of the network with connections to the upstream providers, in order to
defeat the possibility of source-address-spoofed packets from entering
from downstream networks, or leaving for upstream networks.

Paul Ferguson of cisco Systems and Daniel Senie of BlazeNet have written
an RFC pertaining to this topic. See:

ftp://ftp.isi.edu/in-notes/rfc2267.txt

for more information and examples on this subject.

Additionally, router vendors have added or are currently adding options
to turn off the ability to spoof IP source addresses by checking the
source address of a packet against the routing table to ensure the return
path of the packet is through the interface it was received on.

Cisco has added this feature to the current 11.1CC branch, used by many
NSP's, in an interface command '[no] ip verify unicast reverse-path'.

See the "other vendors" section for 3Com information regarding this feature."

Subject : Web Input compare against Network Users
Private : No

Question : Sir,
I am wondering if you would kindly enlighten me on the way of how to programmatically obtain the registered users of our network.

I am developing our website with a portion in it that requires the user to enter first his userID and password before he will be allowed to gain access to our downloading system.

To this end, I plan to write a program that takes two string arguments (username and password inputted by user from the web page) -- once the submit button of our webpage is clicked I want to compare said two strings against the list of all the people who have login name and password in our network --

I am planning to design that program in such a way that it will return a boolean -- true if the user name and password entered in our webpage's form matches a person in our network and false if it doesnt.

Currently our customers have logon username and passwords into our network and my boss wants me to use that list -- maybe one of the fastest way at the moment is to copy those things manually, but then from which file? Also the list grows indefinitely and without warning -- I will have to have a programmatic way of extracting them from our network -- is this at all possible? We are using Windows NT 4.0 and Novell 5.1 with a Netopia Firewall and IIS 4. What is the best way to carry out this task?

Thank you so much for all the kind help you can give.

Gratefully,
Matt

Answer : You will likely need to get an API (Application Programming Interface) specific to Novell and Windows NT 4 to be able to check if a user's password matches his name. I don't know of any NOS that allows you easy direct access to a user's name and password as it's a security hole.

I am responsible for a small network (40 users). We have 2 servers, both run win2000. One is our file, print, and email server, and the other one is the terminal server.

I recently installed sr-2 on both machines. Now the terminal sever wont let anyone in. I installed the software on a machine in the building and used a 192.. ip address that identified the terminal server. I am able to connect that way. I have tried everything I know. If you want, you can contact me at bsims@citizenschool.com and I will share log files with you if it will help.

Thanks,

Answer : If you're able to get to the terminal services machine by IP address then your problem is with name resolution - check your DNS settings all around, and try accessing the TS server by fully-qualified name (i.e. instead of "myhost" connect as "myhost.mydomain.com").

I think I'd like to set up a wireless network but I'm not sure how hard this will be. Any recommendations?

Answer : I'm not sure what wireless systems would work between these, but I suspect using 802.11b(wireless) Ethernet will get you interoperability between the two platforms easily.

As for normal networking (or after you get wireless working) and sharing - that's not a problem. Since the Mac speaks the same protocol as the PC (TCP/IP) you will have no problems sharing the internet connection between the two. Just get yourself a broadband DSL/cable-modem router like the Linksys or Netgear ones (search at any computer site online for "cable router" and you'll find it - a good place to start would be http://www.buy.com). Be sure and get one with 4 ports or more so you can plug in both PCs, as well as your DSL/cable connection. Configure it as normal (IOW no special steps due to a Mac being on the network) and you're all set.

i have juz got myself a new labtop, its a "Sony VAIO" running windows XP. my old desktop rums win98. both machines have lan cards but i do not know their exact models and specs. i have followed the instructions in XP's "network bridge connection". it has created a setup disk for me to install in the desktop machine. but i cant get the two machines to connect to each other. i have double checked that all the cables are plugged in.

what shall i do?

Answer : Just go and buy a "crossover" ethernet cable. Plug it into each machine's ethernet cards and assign each PC a unique IP address on the same segment (assign one 10.0.0.1 and the other 10.0.0.2, both with subnet mask of 255.255.255.0 and no default gateway). Now ensure you have file and printer sharing enabled in both and you can open your Network Neighborhood or My Computer and type in:

\\machinename

where 'machinename' is the name of the other machine and see a list of his shares. Share your drives by right-clicking the drive letter (or folder if you prefer to not share the whole disk) and selecting 'Sharing'.

but it said it was unable to open the file (did not specify which file).Can you tell me how to use winPcap with Borland C++ as I am hessitant to use Visual C++ as it is more complicated.
Thank You.

Answer : It said "unable to open the file" or it said "bad command or filename"? Try running the following by themselves:

implib

implib /?

and see if you get back a response tht at least lets you know the implib EXE is being found and run. If you get confirmation it is then move on - if not then cd to the directory where the implib.exe file is located before running the command, as it is not in your PATH environment variable. For example if you find that typing implib by itself results in the "bad command or filename" type of message (meaning the file is not found) and you know the file implib.exe is at "C:\program files\mystuff" (find it on your harddisk with Start/Find/Files and Folders) then type this:

c:
cd "\program files\mystuff"

and THEN type:

implib
implib /?

You should then for sure be running the command correctly. At that point ensure that the file "PacketBCB.lib" is in the same directory with you as well. If you need to copy it from wherever it is now to the same dir as implib.exe. Once they are both together in the same directory then run:

implib -acf PacketBCB.lib packet.dll

to generate your file.

Question : Hi pauldoherty,

I am a mechanical engineering student. I am doing a project which deliever an experiment on the Internet. However, I have to connect from a 386 computer running Window 3.1 to a newly ordered server, which would run on NT. As a result, could give me advice on how to connect this two machine effectly. It is because during experiment large amount of data would be transmitted and then go into the Internet.

Thank you very much.

Need More Information : Are both machines equipped with ethernet cards and on the same network (LAN)?

FUQuestion : Oh yes, forgot to tell you how they connected.

For the connection between them. I jwould like them to have a one to one connection. As the old machine don't have the capability to do real networking.
The available port for the macine are one parallel and one serial port.

Answer : I have a really old utility I've made available for you on my website. It's called XPORT.EXE and is used between two machines in DOS. You'll need to connect both machines with a null-modem serial cable and then run XPORT.EXE on both machines. It's very easy to use and you can transfer whatever data you need from one machine to the other. The best way to do this would be to:

1) Collect all the data on the machine that has the data to be moved into one large zip file. If the machine is the Windows 3.1 box and you have no internet access for it go and download a copy of pkzip.exe with your other machine and copy it to a floppy to move to the 3.1 machine. Once it's there use the following syntax to zip up a directory:

c:
cd \directory\to\be\zipped
pkzip -pr c:\backup.zip *.*

Afterwards you will use XPORT.EXE to simply copy the backup.zip file to the other machine where you will use WinZip (http://www.winzip.com) to extract the original files and directories.

You can get pkzip.exe here:

http://www.wright-systems.com/pkzip.exe

and get XPORT.EXE from my site here:

http://ped.deadartists.com/XPORT.EXE

Finally you can order a null-modem serial cable here:

http://www.cables.com/miva/merchant.mv?Screen=CTGY&Store_Code=CARA&Category_Code=MDM

(press CTRL-F and search for "null" without the quotes - be sure to get the ends to match the serial ports of both machines - DB-9 pin or DB-25 pin will be the ends based on the PC type).

FUQuestion : Hi pauldoherty,

Since I am waiting for the new computer to be connected, I try to install Xport to the Window 3.1 machine. Now, I found a problem. For this project, it should be run the experiment program and transmitting the data at the same time. Is it possible on Window 3.1? Or can I build a newtwork to solve the problem?

Thank you very much


Answer : Xport needs to be run at a DOS prompt, not in Windows. Also the way xport works is to poll the serial port, looking for the other machine. If you just run it on one machine it will sit there waiting for a connection from the other machine. So until you get the null modem cable you really can't test it other than just to see that it loads successfully.

Answer : Most PC ethernet cards (PCI) have their MAC address burned into a EPROM on-board the card and are not changeable (for obvious good reason). Without changing that EPROM contents I don't think you can do it. Some proprietary systems like Sun UNIX machines can do this as their MAC is stored in the main EPROM that is editable, although again it's unwise to do it without a good reason.

I am trying to find commands to use that free disk space using something like ln command but I dont have exact idea of commands in sequence and how to check which partition I can use.

I will be grateful if you can help me solving this problem and guide me in right direction.

regards

Answer : If you know the name of the directory in which the patchadd needs to work (say /usr/stuff) and the filesystem that has the space you want to use is /var/run for example, you can do this to utilize that space:

su - (to become root)
mkdir /var/run/tempstuff
cd /usr
ln -s /usr/stuff /var/run/tempstuff

Now when your patchadd references /usr/stuff it will actually be accessing the directory /var/run/tempstuff and using the space off *it's* filesystem instead of off the /usr filesystem.

Answer : A router will never make a very good firewall.

Question : good evening sir, i have a query, please answer.

thanks a lot.
Sandeep.

Need More Information : Are you referring to the classes of internet addresses (TCP/IP)?

FUQuestion : yes sir, i am talking about TCP/IP.
please reply.
thanks a lot.
snandeep.

Answer : TCP/IP uses addresses like 24.143.91.202, which are 32-bit numbers broken into 4 "octets" of 8 bits (one byte) each. The value of the first octet determins what "class" an address belongs to. A value of 1-127 is one class, while a 128-191 is another. The classes were just a way to divvy up the addresses for use, and likely for efficiency (a router or other network device can tell quickly, by examining the first couple of bits of a destination address, whether a packet will be within its purview). The primary classes break down as follows:

Class A 0-127 ("0" is actually not available for workstation assignment by convention, and 127 is a diagnostic address (ex 127.0.0.1 is your loopback address)

Class B 128-191

Class C 192-223

The other address ranges starting with 224-255 are reserved for other purposes.

Note that class A addresses beginning octet will all start with the binary representation:

0

All class B addresses will start with:

10

And all class C addresses will begin with:

110

That is what I was referring to above when I said a network device can quickly eliminate traffic if it examines the first two or 3 bits of the destination address since those determine the class of the network to which the packet is destined.

If two network cards would increase performance by even 25% it would be worth it, until we could make the switch to gigabit ethernet?

Thanks
Derek McTighe

Answer : If your workstations are on the same LAN I would think you could. What you would have to do on the workstation end, however, is to specifically attach to one or the other IP of the server in order to distribute the load so both cards are being used properly. If your LAN involves routers (multiple segments to your Ethernet LAN) you will need to setup some routes on the server with two NICs to direct traffic which is destined for each internal network segment. This would automatically load-balance your traffic to some degree by segregating which card handles which networks.

Subject : Unix Script Problem
Private : No

Question : Hi,

I am using the following in my scripts:

custpo=`grep "ORD_I_HE" $i | cut -d"*" -f10`
custno=`grep "ORD_I_HE" $i | cut -d"*" -f5`
cat $i | sed "s/^/${i}*${sysdate}*${custpo}*${custno}**${currency}*/g" >> testfile.dat

The value of custpo is being picked up from the file.

Assume now that the value of custpo is ABC/123.
i.e custpo = ABC/123.

If that is the case then sed command will fail, showing that sed cannot parse.

I tried to hardcode the value as ABC\/123 and after that unix script is not failing.

Pls, advise as how can i tackle this "/". Since this "/" may be many time in my data file as a part of the data.

Answer : I'm not sure how to modify the sed line to ignore those but one thing you can do is to modify the line before running it through sed, and then change it back after the sed is complete. For instance:

tempcustpo=`echo $custpo | tr '[/]' '[&]'`

This will change all forward slashes (/) to ampersands (&). You can use a different character (or group of characters) if you like. Then you can sed your data into another variable, use tr on it to switch the &s back to /s and concatenate it to your testfile.dat file.

Question : Hi,

I have a problem. I have been receiving strange emails within my Hotmail account from some unknown individual. These messages contain rude details and i am very much interested in tracking down the culprit behind them. However, when i view each message's Header Details so as to identify the Originating IP adress i ALWAYS find that the IP address is actually MINE (or some fake one that is NOT a proxy)...now obviously i am not the originating person who is sending these rude emails so it is clear that this other person (hacker) is "Modifying" these message headers in a way so that his REAL IP address is hidden so i cannot take action. Is a hacker able to modify Hotmail Message Header's so that his IP Address as seen in the message is actually changed to my IP Address when i receive it? I notice that this person is NOT using a Proxy so that is not the case.

Is there information on the net (url's) that i can refer to that helps better educate me on how a hacker was able to do this and how one can go about tracking this person (or protecting oneself against).

Thanks very much
Jason Lane

Answer : Yes it is quite easy to send anonynmous emails. There are many services on the web and clients you can download to do that. I'd suggest you dump that hotmail account and make another if that one is compromised.

File sharing ...what are the ads/dis and issues with file sharing?

Answer : A printer should go where it is most convenient to users. I'd suggest getting a network printer (one with an Ethernet connection) that can stand alone.

DSL is nice for homes, but using it for an office could be problematic unless you get a SLA (Service Level Agreement). Outages can be frequent with residential services. Upstream bandwidth is also usually capped quite low at 128 kbps or 256 at most.

Sharing files over the network is one of the primary reasons for installing a network. It opens up some security risks, but if you use a domain controller (NT/2000/XP Server) to control authentication you'll be fine. Also be sure your internet sharing mechanism is secure.

Question : Hi,

I saw a hardware component called a buddy system several years ago that allowed you to have one computer, but up to 4 workstations. The buddy system let you hook up 4 monitors, keyboards, and a mouse and then shared the resources of the one computer eliminating the need to purchase multiple systems. I believe it's no longer available, but would like to see if it's possible to setup a system along that same line.

I would like to have a computer set as the server and run a network inside a child care facility that would only require a monitor, keyboard & mouse in each classroom, but be able to run applications off of the main server. Is this possible to do?

Thanks for your help!

Answer : Windows offers an advanced server that has a feature called "Terminal Services" (also known as "remote desktop") in Windows 2000 and Windows XP. It will allow remote machines to host sessions on the main server - they can all be logged in and run apps from that main server. The storage and processing is done by the main server so the other PCs can be very lightweight machines (slower CPU with very little storage). I suggest you look into that.

Question : I wish to setup a wireless network in my home to share the same DSL connection. My DSL currently has an internal modem. What will I need to setup a wireless network to share the same DSL internet connection, with two PCs, one with Windows 98 and the other with Windows XP? I was looking on TigerDirect.com on the wireless networking starter kits page at http://www.tigerdirect.com/applications/Category/category_slc.asp?Id=3505

Is there anything there that would meet my needs?

Thanks!

Need More Information : Clarify the following statement:

"My DSL currently has an internal modem."

FUQuestion : I have a computer with DSL, I want to hook up my other computer to share this connection. I do not have an external DSL modem, it is internal. It is in the computer not outside of it in a box.

Answer : Your options for a wireless sharing network are limited with an internal DSL modem. If it must be wireless a wireless switch can be used, and both PCs would need wireless Ethernet cards. You would also need to be running ICS (Internet Connection Sharing - a standard feature in Windows 98 SE, Millenium, 2000, and XP).

This way the net traffic would come in through the DSL modem into your machine, and then if it was traffic for a different machine, would go out the wireless Ethernet interface to the wireless switch and to the other machine. Setting up such a dual-homed machine on a consumer OS and being a non-expert such as you are I would not recommend this type of setup.

If you must go wireless I'd suggest getting an external DSL modem and wireless NAT router (Linksys, NetGear, DLink, etc) and removing the internal DSL modem. Using this configuration the phone (DSL) line would go to the external DSL modem. From there it comes out as Ethernet and goes to the wireless NAT router which handles the address translation necessary for more than one machine to use the DSL line. This has a few advantages:

1) Speed - no one machine is the carrier of traffic for the other - both get equal speed.

2) Less overhead - Neither PC is wasting resources working as a traffic cop.

3) More robust - either PC can be rebuilt, rebooted, whatever, and not interrupt the internet traffic for the other.

4) More secure - Neither PC is directly on the internet (since they both are being passed through the NAT router). This acts as a natural barrier to attack since the NAT router will not allow outside attackers to start a conversation with your internal PCs.

Question : I bypassed all network settings during install of Linux vs 7.0. After boot up it says: local host login:
During installation all it asked for was root password, account name and password. I typed the names I chose for these 3 entries. When it got to the network settings page I skipped that because I'm not on a network. It then went thru all the rest of the installation proceedure. When I boot up it says: Red Hat Linux release 7.0 (Guiness) Kernel 2.2.16-22 on an i586. Below that it says: local host login.
The only info I can type there is my account name and password I gave it during setup. It never asked for a local host login name. When I type my account name it then asks for a password, so I type in the one I chose while it was installing. It then says Login incorrect.
Why? I didn't give it any network settings or info at setup.
Thanks, Jim

Answer : You did two things during install - set a password on the account named "root" *and* created another normal user account and set its password as well. Try logging in as root with the first password you provided - and remember LINUX is case-sensitive.

Question : i have bought and installed two network adapters, one for each computer. I have a computer with Windows 98 which has an internal DSL modem and I want to be able to share that connection with my Windows XP connection. I have the cards installed, they are working, but now what? I am not sure how to get the TCP/IP stuff all up and working. Would it be better to put the DSL modem on my Windows XP computer? Would it be easier to set up then? Or is there a way I can do it with the DSL on my Win 98 computer?

I appreciate your help!

Answer : If you have Win98 *SE* you can do it with either the 98 or the XP machine. If you're only on 98 then you won't have the necessary feature (ICS). You'll want to assign a non-routable address to the Ethernet card in the machine (whichever you end up using) with the DSL modem - use this info:

IP - 10.0.0.1
Subnet Mask - 255.255.255.0
Default Gateway - Use the IP provided by your ISP for their gateway. May be able to leave this blank if you're unsure of what IP to use.

On the second interface (DSL) on the machine with DSL set it to DHCP so it automatically get its IP and other info.

On the second machine's Ethernet use:

IP - 10.0.0.2
Subnet Mask - 255.255.255.0
Default Gateway - 10.1.1.1


Now install ICS on the machine with the DSL modem to share the connection. Go to the Add/Remove Programs control panel and under the Windows Setup tab you should be able to click Add and find it in the list of software.

FUQuestion : How do I install ICS on my 98 FE computer?


FUQuestion : One more question, on my XP Machine in the TCP/IP settings, it wants me to supply DNS settings. It won't let me "disable" the DSN settings because I supply an IP address. Here, let me explain:

There is a button in the TCP/IP settings that I have to click which is something like "Specify An IP Address", and since I click that, it wants a Primary and Secondary DNS address. There is a button there, that says Disable DNS, but I cannot click that if I have the "Specify IP Address" button clicked. Let me know if you understand.

Do I need to supply a DNS address or can I simply leave this?

Thanks!

FUQuestion : Sorry, but I have another question :) How do I set my DSL to DHCP?

http://www.dewassoc.com/support/networking/ics_2.htm

As for installing your DSL I have no idea what device you have or who your ISP is. They should have configured your DSL for you when they came out to activate your service, or at the minimum provided you with a guide to installation.

i will be on the internet on my client comptuer and i will all of the sudden not be able to surf the web, i have to restart my client computer before the internet will work again. At first I went to my server computer which has WIN98 and i checked everything because i thought maybe something happened with it, but everything is working fine on that computer, so i know it has something to do with my client computer which has WIN 98...i have checked the settings there is no time-out setting or anything...any tips?

Need More Information : Ensure at a low level that you've lost connection by opening a DOS prompt (Start/Run/cmd) on the XP machine and type:

ping 10.0.0.1

and see if any replies are received.

If they are then the problem lies with the 98 machine and its ICS configuration not passing traffic correctly. If no replies are received then your LAN hub/switch or the cable you're using from the XP machine has a problem.

Question : hello paul.

if there's an IP with more than one hostname pointing to it, is there a way I could find out and list these hostnames? or is it not possible?

thanks.

Answer : If you perform an nslookup you can do it in both directions and get the aliases by which an IP is known. For example, I did this nslookup on 'cnn.com' just now:

D:\Documents and Settings\pdoherty\Desktop>nslookup cnn.com
Server: chnms01.cp.ipsvc.net
Address: 24.128.1.80

Non-authoritative answer:
Name: cnn.com
Addresses: 64.236.16.84, 64.236.16.116, 64.236.24.4, 64.236.24.12
64.236.24.20, 64.236.24.28, 64.236.16.20, 64.236.16.52


The last section are the IP addresses that correspond to that name, any one of which may answer to the query depending on which you get that time around (many DNS lookup servers utilize a "round-robin" approach to load-balancing to route traffic alternately to multipl machines to distribute the load for the site.


If you do an nslookup in the opposite direction you can see what name points to the IP, though I think this will always result in just one name being returned:

D:\Documents and Settings\pdoherty\Desktop>nslookup 64.236.16.52
Server: chnms01.cp.ipsvc.net
Address: 24.128.1.80

Name: www4.cnn.com
Address: 64.236.16.52

I can ping both addresses from one the first machine but the second consistently returns the message "PING: transmit failed, error code 10091." when trying to ping either address. Also, on this machine, winipcfg returns "Fatal Error. Connot read IP configuration".

Answer : You definitely will never get it working if pings result in that error message. I suggest you reinstall 95 over the top of the existing install to see if it can sort out what file is a wrong version, or what setting is wrong. If you've already removed all network components and restored them and it's still there then that would be the next step. This won't wipe your existing install - all apps will still be there.

\\192.168.0.2

where the IP address is the IP address of the other person's machine? That should show you their machine and everything they have shared.

Subject : cannot perform rconsole command
Private : Yes

Question : Hello

I recently installed Windows 2000 professional on my computer
I used to have OS Windows 95 in which I easily could perform the command rconsole in order te connect to one or several novell servers
Our novell servers run on 3.20
I might have overlooked something while configuring (actually I didn't do anything special at all since I'm not really an expert on networks etc)
Upon trying to connect I get the following error
The driver failed to initialize. The following error was returned "IPXinitialize failed"
Can you help me out ???
Thanks in advance

Need More Information : Do you have the IPX/SPX protocol installed? Check in your Network control panel. Open it then right-click your LAN connection and hit Properties. Once inside look for the TCP/IP and IPX/SPX protocols to be installed. If you don't see IPX/SPX add it (it will be under Microsoft after you click Add).

FUQuestion : Yes I have installed the Ipx/spx protocol
I have the NW Link IPX/SPX/Netbios Compatible Protocol which is currently used by my connection

Need More Information : I assume you've installed the Netware client to this machine, and have a search drive mapped to SYS:Public?

Answer : Yes, they are. You ended up at the destination you sought, and with no "black holes" along the way.
Rating : 5

FUQuestion : Just wanted to let you know I rated your answer a "5" for a timely response!

Answer : No answer required (and you're welcome :-)

FUQuestion : Maybe this is an actual question, heh, just following up ...

Hi, I ran quite a few traceroutes from this web site (URL - http://www.tracert.com)... Our IP: 204.80.132.5

* Athens, Greece
National Technical University of Athens
* Moscow, Russia
Parkline - www.parkline.ru
* Fort Lauderdale, Florida
Dialtone Internet
* Buffalo, New York
Blue Moon - ISP

How can I verify and confirm that IF this tool that I am using is imbedding the ICMP packet in HTTP, hence being able to penetrate through a firewall from external sources? When traceroutes are run from the other locations listed on their web site, except for the four listed above, it gives 100% packet loss --- which it should --- due to the firewall. Much thanks for clarification :)

When you run traceroutes from the other locations listed, it gives 100% packet loss --- which it should --- due to the firewall.

Answer : I guess one way to test would be to put some type of sniffer outside the firewall and have it filtering for packets coming from the tracrt.com server's IP address. Once those packets arrive you can see what port they're coming in on.
