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.

I was setting my my mail server and looked at the e-maill address and decided that I didn't like it, It ends in the @localhost.localdomain. This is was is in my host name and I was wondering if I can change that host name or not?
What I am trying to do is set up Evolution of my computer. When I go through the set up wizard at the begin, It has two fields that are already filled out, one is my name and the other is the e-mail address. The one that is given is my firstname.lastname@example.org and when I looked at my host name in my Internet connections, that is the given user name. Is there a way that I can change this to something different or am i stuck with this as a host name?
I think you're meaning:
You can do, as root:
Newname > /etc/hostname
Newname > /etc/domainname,
and that should change you're host/domainname.
Don't know if this is what you're meaning, but trying this can't do to much harm, especially not after:
cat /etc/hostname > /etc/hostname.old
cat /etc/domainname > /etc/domainname.old,
and then doing the above, so you've got a backup.
When I start my computer up, I see a mesage that the dhcp fails to start up. how do I fic that problem, plus whwn I exit my kde, I see a message that say Unable to get hostname, your system is misconfigured. I've found some files that have my original host name in them, but I can't seel to get the computer to see them
I'm sorry if I messed things up for you in first place, didn't meen to.
But, I hope you made a backup like I said, so you should set back the backup, like:
$ cd /etc
$ mv hostname.old hostname
$ mv domainname.old domainname.
Now, I gave you some wrong advice maybe, their exists a command to change your hostname.
If I want to change my hostname to foo, logged in as root, I type:
# hostname -v foo
which gives as output:
Setting hostname to `foo'
Then it works, and after you simply issue:
with no arguments, it says:
domainname works the same, issuing dommainname in the command line with no arguments yields your current domainname, and saying domainname followed by a name sets your domainname to that name.
