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.

Hi, I've read the Howto's and the extremely helpful threads in this subject, but after four days of changing this and trying that I'm still not having success. OK I installed Mandrake 10.0 official on a dual pentium HP box. I installed shorewall thru drake. I updated shorewall to 2.2.0-1 and successfully copied the files for a two interface setup. I want to use the Linux box as a firewalled router and connect my second box running XP with internet access for both boxes. My Linux box has two nic cards. My ISP provided me with a static ip address and the two dns ip addresses. My topology has been my ISP's modem connected to DLink router connected to a hub and my two boxes connected to that hub(My Linux box accesses the internet with no problem in this setup). I would like to replace the DLink router and use my Linux box instead.Also, I would like to use IP Masquerading SNAT. Can someone please help me make this work? I want to wean away from gui and master the command line so instructions in this format would be awesome. Please instruct if I need to post more info
