HOSTNAME=hostname, where hostname is the hostname of your server.
GATEWAY=gwip, where gwip is the IP address of the remote network gateway -if available.

For compatibility with older software, the /etc/HOSTNAME file should contain the same value as HOSTNAME= hostname above. With the new version of Red Hat Linux 6.2 the FORWARD_IPV4= parameter is now
specified in the /etc/sysctl.conf file instead of the /etc/sysconfig/network file.
