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.

ok if i have a webmail portal and an http server set up on the same machine under the same dynamic domain name, how do i keep them seperate? should i add another host with a subdomain like mail.mydomain.com? and if so how do i tell it to link to the webmail portal port instead of port 80, when i have a dynamic dns? or is all this even possible?
If your running both that natively want to use port 80, make it so your webmail runs on another port, say maybe 8080 and tell your Dynamic DNS service to have it forward the requests on that port, if they even do that, etc.
I found a simple solution to this problem which was to use an URL redirect to the webmail server, using the correct port number in the shortcut. It cloaks that ugly looking arrangement however and everything comes out all neat and proper.
