To make a permanent host name change on Debian edit the /etc/hostname file. Replace the contents of the file with your new host name.
Then run: /etc/init.d/hostname.sh start
This will make the change active, you can check the host name by using the hostname command.
Then run: /etc/init.d/hostname.sh start
This will make the change active, you can check the host name by using the hostname command.

On Debian/Ubuntu Linux, hostname is set in two files: /etc/hostname and /etc/hosts.
- /etc/hostname: short hostname, not FQDN.
Code:
mx- /etc/hosts: static table lookup for hostnames. Warning: Please list the FQDN hostname as first item.
Code:
127.0.0.1 mx.example.com mxMX is the host name in this example mx.example.com is the FQDN
No, you do not need to add the host name after the FQDN
Either of these examples with /etc/hosts are fine:
127.0.0.1 servername.domain.com
127.0.0.1 servername.domain.com servername
No, you do not need to add the host name after the FQDN
Either of these examples with /etc/hosts are fine:
127.0.0.1 servername.domain.com
127.0.0.1 servername.domain.com servername
