Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Okay, I gave up on dhcp and have my linux box getting an ip of 192.168.1.150 from the router. Whenever I ping the router (192.168.1.1) I lose about 90% of the packets. Same loss when I ping an ip outside my network (18.104.22.168).
I'm sure the wire works fine, I moved it directly from my working win98 machine to the linux box. My DNS isn't working right yet, but I'll worry about that later.
Can anyone give me anything to check before I assume it's a hardware problem with my 3com nic?
what kernel version are you using? I switched from 2.2.19 to 2.4.12 or something like that and my 3com card started dropping packets like a mofo.....this was with both Debain and Slakware...so it seems to be distro inspecific......
The card is a possibility, but like I said, I changed to 2.4, didnt change any perameters...and the card slowed way down....when I revert to 2.2, it works fine........it may not be a hardware issue...try a diffferent driver or kernel....or try it in a different OS before you say the card is wasted.
uname -r from a console prompt will tell you what kernel you are using.
RH7.0 should have a 2.2.x kernel..
If you can ping your localhost just fine, then check your cable if that is fine and you are sure your hub/router is fine, then go ahead and try the NIC in a computer you know is working. Other than that you could recompile your kernel and make sure you have support for your NIC compiled in.
a BIG pita I have run into...
ltsa cable modems/routers/stuff
are set for half-duplex
(and some auto-negotiate the speed)
and croak if your network is the
wrong duplex....you are half, it is full or vice-versa.
