How do I change my hostname? [RESOLVED]

I see that HOSTNAME="myhost" is in my /etc/rc.conf file.
If I want to change it, do I simply edit the /etc/rc.conf file or do I need to edit other files as well?  Or can I just run the hostname command?

Yes, just edit rc.conf and add your new hostname to /etc/hosts on the same line as localhost.

If you also want to change the "name" of what gets resoluted to "127.0.0.1", change

127.0.0.1               localhost.localdomain   localhost

to something like

127.0.0.1               r0flcopter.localdomain   r0flcopter

in /etc/hosts too.

some daemons might listen explicitly on localhost:portxy though, so you have to make yout changes there too (r0flcopter:portxy).. was like that for cups once at least.

You can just add two lines though:
/etc/hosts

127.0.0.1 localhost.localdomain localhost
127.0.0.1 r0flcopter.localdomain r0flcopter

(cf blocking ads using your /etc/hosts file)

you can string them alltogether on one line. I would make sure 'localhost' is included whatever you do -many program look for that.
