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.

This is a very basic question so feel free to tell me to RTFM- point me at a tutorial or something.
I have three PC's connected to a linksys router. Everything works fine, but based on which one is turned on first, they get different ip addresses on the lan. How do I make them stick to thier ip address? I want:
windows box: 192.168.1.100
linux 1: 192.168.1.101
linux 2: 192.168.1.102
You need to change their configuration from a dynamic IP assigned by DHCP ("get IP address automatically" in windows) to the appropriate static IP. Also double-check your router configuration to make sure it will allow static IPs (most will have some blank where you can say that you have 100-102 assigned statically, so it won't try to give those IPs out to any other computers)
pingswept thanks for your persistence and patience. I figured it out. It was me. (of course).
What happend was, when I edited ifcfg-eth0, I made a copy if it first, in the same dir. What I didn't know is that everything in that directory gets run. I was thinking it was like other conf files like fstabs or httpd.conf, where you should make a ".old" copy before you make changes, in case you screw something up. The name of the copy I made was aphabetically greater than "ifcfg-eth0", so it was running after ifcfg-eth0 ran, and therefore overriding it.
Curiously, the way I found out about this was I tried to do the same thing on my Mandrake box, and during reboot it listed the copy file and said "sorry, eth0 is already setup, not running this config". Redhat doesn't do that check, it just runs whatever. Interesting, right? Chalk one up for Mandrake.
