With all your files edited and saved, you should reboot so the new name and configuration will be used. Reboot the system and then use ifconfig or ipaddr to confirm that your new configuration is available. You can also use hostname -f to verify the hostname change,.

To give users the ability to control the interface, create a clone by copying ifcfg-eth0 to ifcfg-eth0-user and add the following line to ifcfg-eth0-user :.
