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 was only tested with Slackware, but should work on almost every other distribution and even for Windows.
Assume this is your setup:
A --> B --> Internet
You want to connect A to the internet, B is already connected.
Run this
Code:
if [ -f /proc/sys/net/ipv4/ip_forward ]; then
echo "Activating IPv4 packet forwarding."
echo 1 > /proc/sys/net/ipv4/ip_forward
fi
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
on B as root and this
Code:
route add default gw $(ipadresse of B)
on A.
Done. Isn't it great?
You could setup a DHCP daemon on B to automate some things, but there are other HOWTOs for that.
