You need to use the hostname command. It is used to either set or show the current host, domain or node name of the system. Open a command-line terminal (select Applications > Accessories > Terminal), and then type:
$ hostname
Sample outputs
vivek-laptop.nixcraft.in
Where,
- vivek-laptop : You computer name.
- nixcraft.in : Your dNS domain name.
- vivek-laptop.nixcraft.in : Your computer name with Fully Qualified Domain Name (FQDN).
$ dnsdomainname
Sample outputs:
nixcraft.in
How Do I Change My Hostname?
The hostname commands set the host name using the following syntax. Please note that only the super-user / root can change the names. To switch to the root user by typing su - and entering the root password, when prompted.# hostname newhostname.nixcraft.in
# hostname laptop.nixcraft.net.in
