Exactly what sets the hostname is going to depend on which version of
which linux dist your using, and also if you have a network card
configured properly.

If its a recent redhat then the hostname should get set from the
HOSTNAME value in /etc/sysconfig/network. You should also check that the
values in /etc/hosts look sane.

To be sure exactly what is setting your hostname, and clues as to what
to do to make it set it differently, search through your
/etc/rc.d/ directory for mentions of the 'hostname' command, which is
used to both print, and set the current hostname.

If it is always coming up as localhost then i would assume that you have
no network cards configured, or have somehow missed a chunk of the
config.
