The current Full Qualified Domain Name, in short FQDN is setup via the /etc/hosts file.

FQDN entry for static IP address:

File: /etc/hosts

127.0.0.1       localhost
::1             localhost

192.168.0.123   machine1.domain.local        machine1

Note: The following isn't necessary when using systemd as it configurates everything correctly.

FQDN entry for dynamic IP address (e.g. via DHCP):

File: /etc/hosts

127.0.0.1       machine1.domain.local        machine1        localhost

If everything is correctly configured a

# hostname --fqdn

should output the full FQDN.

Code: Output

machine1.domain.local
