set host-name failed on Ubuntu vivid

Question

With Ubuntu vivid, I cannot bind the hostname of my server with the IP address gotten by a DHCP server

I tried to add in dhclient.conf (and reboot)

set host-name "myserver";

But, still doesn't work...

Did I miss something ?

Answer 1

If you already know the name, edit the /etc/hostname and run:

hostname $(cat /etc/hostname)
