hostname and hostname -f are backwards?

Question

When I run the command hostname (on Ubuntu 10.04 LTS Server) it returns 'mail.mydomain.com'

When I run hostname -f I get 'mail' as a response.

These seem backwards to me, shouldn't hostname -f return the FQDN? Where did I misconfigure this?

Yes, hostname -f should return the FQDN. Try:

There are probably other ways to do it; that's just how I have my system configured (and it seems to work).

	The changes to /etc/hostname worked beautifully. When running hostname -f I still only get `mail` instead of the FQDN. I did add `domain mydomain.com` to resolv.conf as well. (Rebooted for good measure to test too. :) – Citricguy Jul 25 '11 at 2:45
	I think the next step would be to check `/etc/hosts` and add an entry there, if appropriate. Let us know! – fission Jul 25 '11 at 2:47
	Had to add the entry to hosts as well `127.0.0.1 mail.mydomain.com mail` :) Thank you for the help, couldn't have done this without you! – Citricguy Jul 25 '11 at 2:51
