[wplug] setting hostname

	The domain name and hostnames are usually different, and should be 
treated as such. A fully qualified domain name reads as host.domain.com.

	The proper way to do this, is to simply change the hostname. On
Redhat systems, the hostname is set in /etc/sysconfig/network. On other
systems, it can be /etc/HOSTNAME, or /etc/hostname, or it can be set in a
different place. You can use the hostname command to change the hostname,
but you'll have to logout and login to see that change.

	If you have a system that already has a hostname, but you want it 
to appear differently, editing /etc/profile, and setting the hostname in 
there will make it appear like the host is different. Like someone else 
said, you can edit the /home/user/.bashrc or .bash_profile to lie to the 
user about the hostname.

	You can also edit files in /etc/skel/ (like .bash_profile or 
.bashrc) to again lie to the user about the hostname.

	The domain name is set in /etc/resolv.conf -- you should have a 
line which says:

domain something.com

	Good luck!
