  1. edit: /etc/hosts
127.0.0.1 srv03.mil1.wide-net.org localhost.localdomain localhost

  1. edit: /etc/sysconfig/network HOSTNAME=srv03.mil11.wide-net.org

  2. past into kernel new hostname echo "srv03.mil1.wide-net.org" > /proc/sys/kernel/hostname

Or

sysctl kernel.hostname=srv03.mil1.wide-net.org

Consider a restart net services /etc/init.d/network restart but is not strictly required.
