In my last post i have described how to configure network in Ubuntu 10.04 LTS in bare metal form. Now we will check how to configure hostname in Ubuntu based distributions. First of all let me asure that the process of seting up hostname is very straight forward in Ubuntu 10.04 LTS.
You can directly query or set the hostname with the "hostname" command.
The current hostname can be viewed using:
# sudo /bin/hostname
To set hostname you can use the command:
# sudo /bin/hostname demo.demoserver.in
NOTE: Need not to say that you should change the hostname from demo.demoserver.in to your requirements.
While rebooting Ubuntu based distributions will read the hostname from /etc/hostname file.
So you can open the file /etc/hostname in your favourite editor and specify the hostname there to make the change persistant.
# sudo vi /etc/hostname
# specify your hostname here.
