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.

Asker : too_cg
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.

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.

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

Primary partition (C:) (for ME/2000 OSs) of 3 GB
Extended Partition (data for ME/2000) of 12 GB - create one logical volume of

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

If i want to use redhat to surf the internet, what type of modem i'm going to

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

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

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.

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

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:

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.

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.

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

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.

Subject : Hardware direct access in dos...
Private : No
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.

Question : I had ADSL modem on my W98 PC and everyting was ok but then I made me

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.

tank you very much. This is the soloution to the problem:
In ICS(Win 2000) there is possibility to bypass this packet dropp(incoming

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.

Subject : Sharing a cable modem using a hub

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.

Subject : DDNS

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.

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

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

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

Question : I just purchased a new notebook and find I would really like to keep
some files Synced between both systems, Outlook being one.
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, I’m 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.

Subject : linux apache web server
Private : No
Question : Hi,
I have a fairly decent computer that I want to convert into a Linux server. I
want this server to act as a web server with Apache and support php and mysql.
(I have heard Linux comes wrapped with these things)
So essentially I want to create web applications to be served up by this
computer. 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.

How can I change them back and prevent them from being changed on rebooting

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

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.

Subject : Command-Line Command

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?
Thanks!

FUQuestion : This program seems very useful.
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

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:
