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.

when i am connected to the network at work with my laptop Redhat 9 loads quick and fine, but when it is not connected to the network it takes ages (like 10 minutes!!!!) and hangs inparticular on 'sendmail' for ages, how can i stop this happening so that it always loads normally.
for uninstalling packages you go to what would be the start button if you were running windows, system settings, then packages. This is how you get to it in KDE Red Hat 8.0.
as far as run levels i'll try to tell you the little bit i know about it. You can sort of compare it to safe mode in windows if you are fimilar with that. Run levles depending on what you pick has certain pieces of programming that won't run. I think it is run level 1 that doesn't allow network connetions. there should be some good info on run levels if you do a search on google or maybe one of the more experienced posters can give a more in depth explanation.
i'm a newbie myself, so i'm not 100% sure of the following;
1. in general you don't need sendmail, unless ur running an email server!!
2. after booting, as root run 'ntsysv' choose not to run sendmail
3. u can also run 'service sendmail stop' to stop it immediately without rebooting, should be done as root also
