There is also your /etc/hosts file.  From my experience, in order for hostname
and dnsdomainname to work correctly (they use the underlying system call
GETHOSTNAME(2)), the file should have the following white space delimited
syntax:

    IP  MACHINE.FULLYQUALIFIEDDOMAINNAME MACHINE

This file usually has at least two entries, one for the loopback device
(127.0.0.1) and one for the ethernet device (we'll assume 192.168.20.30).  A
sample file might look like:

    127.0.0.1       localhost.localdomain localhost 
    192.168.20.30   foo@bar.org foo

good luck,
