The "HOSTNAME=" bit in /etc/sysconfig/network should reflect what you
want the machine to be named.

In /etc/hosts, you want (at least) the following two lines:

	127.0.0.1	localhost.localdomain localhost
	w.x.y.z		hostname.domain.com hostname

replacing "w.x.y.z" with the actual IP address of the machine and
"hostname.domain.com" and "hostname" with the appropriate data.
