Personally I would say to use 10baseT. MUCH easier to trace problems... Be
sure to follow the standards for CAT5 cabling... (elect. interference,
cable length, etc... which many installers seem to ignore if they think its
for a home 10mb network... Tell them its for a 100mb network even if you
just start w/ a 10mb)
There are some daul 10/100 hubs out now (komodo and linksys, smc, 3com make
some) that are great for a SOHO installation where you may have both
speeds...
I know of an installation that uses the komodo KNH8 model
(http://www.komodo.com/network/knh8.htm;) and are happy with it...

You can do this with linux policy routing, you need to search for
a document called advanced-routing.ps and iproute2.

I had a windows share that was mounted by smbmount. I removed the share from the
windows side and then tried to smbumount it from the Linux side. Obviously this
was the wrong sequence, now smbumount clams that there is an input/output error
on that mount point. How can I get rid of the mount point ?

yes. Just recompile the kernel with IP Masquerading enabled. There is a
nice IP masquearding mini-Howto you should look into. Things change a
bit as you move from 2.0 kernels to 2.2 kernels. Check the ipchains
howto in case you are using a 2.0 kernel.

No problem...it's best to run it under X that way you can select which
module with a drop down instead of worrying about typing it
incorrectly. In a term type linuxconf...under Networking>Client
Tasks>Basic Host Information
You should see Host Name and 4 tabs for your adapters. Click on adapter
One, put in the revelant information and selectehto as the Net Device
and the ne2k-pci as the module. You shouldn't have to worry about the
i/o and irq, should find it(hopefully :-) Click on Accept and Quit
linuxconf and Activate change, now try and ping the card! Good luck,

Thanks for the responses.
You were right, ifconfig does run fine without root access both on Linux and
on my school Unix account.
I guess what my question really was, when one logs onto a UNIX or Linux
network how does one get the actual host name that will be used by DNS so
that the IP address can be obtained? In my school unix account this
information is on a label on the monitor at the workstation. I'm try to
figure out if there is a standard Unix comand or envionmental variable that
can be used to get this information.
Thanks again,

For future use, you can set resources on the modprobe line in the rc

Try using tcpdump on the gateway to find out where the packets go (or where

When using ZMODEM with cu, minicom, etc. you should use crz/sz
instead of plain rz/sz. Rz/sz is designed to be used in the
server role. Crzsz is designed to be used in the client role.

None of which *makes* a world war. You have missed the point. Define a
world war. In my *opinion* WWII didn't become a World War until the
participants (Britian, Russia and the U.S.) agreed on:
1. Who was the *enemy*
2. What goal(s) for victory
Until this event happened, the war was not unified.
Let's end this useless thread.

RH 5.2 had a 3c515 module, did you try a modprobe? I assume it's not

NetZero 101: Free Internet
You want TOTALLY free internet, like dial up networking freeinternet? Well
you've found the right howto!
First off, you must download Snad Boy's Revalation at www.snadboy.com.
Then you have to wait for netzero to give you an error. The error is cause
when (I think) it's ID server crashes. This is when it brings up a box and
says you need to enter the correct password.... It tells you the username
which is in the format (yes you need the colon) :username(in
lowercase)@netzero.net. Then use snadboy's program to reveal the password
which is standard ascii character such as {}0:' etc....no special keys that
aren't on your keyboard.
After you have that just copy it to a dial up networking connection. and
you're done!! -

I would run DNS locally, to avoid overhead, improve reliability, and to
avoid having to fiddle with every machine for every change. You probably
will get a fair bit of caching, that really helps more than you would
think.
DNS is so simple that it takes longer to think about it that do it, and
then you never have to fight with config everywhere again.

Thomas,
I think we may have a problem here with your topology, or it may be
a problem in my understanding of what you are saying.
Architecture A: (per your description?)
=======cable========(X)============cable=========

(modem)
|
+--------+ +----+----+

|host | | Hub |

Local Network
IF THIS IS YOUR LAYOUT, WE DO HAVE PROBLEMS!
Network access and routing information at the
"(cable modem)" is compromised. You are also
probably forbidden from connecting computers
directly to the (cable) network in an attempt
to use it as an ethernet. Ethernet cable protocols
use baseband transmission, whereas CATV cable uses
broadband transmission.

I am attempting to set up a linux proxy server and
am encountering the same error, when I try to run
the serial port at 115200. The problem goes away
when I run the serial port at 57600, but that is
not really a long term option because we have a
115K ISDN connection, and it is hard to accept
migrating from a faster but limited proxy solution
(A.K.A. a "webramp") to a more open but slower
proxy. I installed a Cyber I/O PCI serial card,
thinking that the built-in serial ports were bad.
It has the same exact problem...it can only run a
reliable PPP connection at 57600 baud. I used
irqtune to move irq 11 to the top priority, and I
STILL get 40-50% frame errors when running the ppp
connection at 115200 baud. SURELY there must be a
way for a pentium II 400 MHZ to handle a 115200
baud connection with a serial port...what do I
need to do to make it work?

Not sharing an interrupt.

Using a scsi hard drive.

Yes, it is.

I'm running 2.2.10, and yes, I did upgrade
net-tools.
