Where is /etc/hostname?

Can’t find hostname to change the hostname.

it’s /etc/HOSTNAME

kdesu kwrite /etc/HOSTNAME


gnomesu gedit /etc/HOSTNAME

Got in /etc/HOSTNAME


But in konsole i see <user>@linux-m8mo . Why is “.site” ?

Leave the .site part and add what you want before it. Eg; Homer

so it would be: Homer.site

In you konsole this with show with your username@Homer

Another way to change hostname is from YaST.
open YaST and choose network and change the hostname there.
