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.

If my lease is not renewed and I am given a new IP address (assume that I dont re-boot) is there a way I can run an application - i.e. I want to drop my firewall and use my new ip address parsing the address from the RH 7.3 file in /etc/dhcpc called dhcpd-eth0.info. My parsing script would be called from /etc/rc.d/rc.local, at boot, but I want to call the parsing script if my ip address changes.
I'm not sure if this will help much, but check out the clients at dyndns.org, one is written in perl and I think it can detect a change in ip address, I would check that out and see how it is written to get an idea of how to make this work
