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.

We have a redhat machine sat on two networks, each network having its own gateway. We want the machine to be able to see both networks and connect to machines through the gateways. We do not want the machine to allow talk between the two networks however.
I set up the two gateways in /etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1, and commented out the default gateway in /etc/sysconfig/network.
# netstat -rn
Kernel IP routing table
Destination____Gateway________Genmask Flags MSS Window irtt Iface
This allows me to ping IPs on the 10.172.xxx.xxx network, includign those that can only be reached through the gateway 10.172.168.254. However, despite being able to ping the gateway 126.96.36.199 I cannot ping anything through it.
Does anyone know what is going on? This is very confusing and any help would be greatly appreciated!
