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.

Booting into single mode doesn't always work. On my Caldera system, after I went through the considerable trouble of adding ' single ' to the end ' kernel ' line from the splashscreen ( lilo is much easier. Just enter ' linux single ' at the prompt. ) , I was greeted by a login prompt. It wanted my password. Fortunately, I was just testing it. The culprit was the inittab file and these lines:
# What to do in single-user mode.
Get DemoLinux and just mount your hard drive Linux partition there and edit the /etc/passwd file, setting root's password to nothing.
If you're using lilo, you can also add the boot parameter "init=/bin/bash", but be very careful, this can get your filesystem screwed over big time, make sure to sync a few times and remount the partition in read only mode before cold booting when you're done!
I tried the backdoors y'all sugested but I completely screwed up my filesystem, by that time it was too late to make backup's.
I could'nt even get into my user acount anymore so I finaly decided to re-install the whole lot. Nevertheless I am still a happy Linux user.
Learn the big lesson: DO NOT forget your root passwd
The way around that is to NOT HAVE a root password. Just kidding!!! Please no hate replies, it was a joke, honest. I would never ever ever suggest to ANYONE, especially a noob, to not have a root passwd enabled. Well maybe I would, but only to someone who is really mean.
