How do i change my hostname from "joe" to "carl" (debian@JOE:~$) ? I've tried the idea with changing it in /etc/hostname, but that just caused trouble with installations and programs.

Personally I have never needed to permanently change a hostname, but one way to do it is described here: http://www.debianhelp.co.uk/hostname.htm

In essence:

echo NEWHOSTNAME >/etc/hostname
/etc/init.d/hostname.sh

You might also need to change it in /etc/hosts (especially if you run into problems with programs as you say).

As far as I know you only have to change the name in /etc/hostname. The new name will be visible when you reboot.

That's true, but if you run /etc/init.d/hostname.sh you don't have to reboot.

debian-installer sometimes put the hostname in /etc/hosts too, so you might need to change it there for programs which expect it. (Some programs need to be able to lookup the hostname so it must either be in DNS or in /etc/hosts.)
