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.

I have a server with 2 network cards. I want it so that if one of them dies, or can't ping the default gateway for whatever reason, the other card takes over automatically with a minimum of down time. My searches for this haven't come up with anything. I must just be using the wrong keywords, I know something like this must be out there.
At work, on windows, we use some kind of NIC teaming software where they work together as the same virtual card with the same IP. One of them can die without the network going down. I need to be able to implement something like this on the Linux server but I don't know where to look for answers.
Exactly as stated above by jlightner. And MOST of the Google hits are indeed for Debian, but are pretty transportable.
You will find in your kernel sources the C code for 'ifenslave' which needs to be compiled and put into /sbin as a binary, which makes creating the bonded interfaces simple as pie and has built-in --help info.
