Current Debian Sarge

I have unsuccesfully trying to chang ethe hostname for w hile now. Most references I find through google either refer to /etc/sysconfig/network (hwich doenst exist I guess for Debia) and the command hostname also changes it only temporarily. I tried editing the /etc/hosts file
which displays

127.0.0.1 localhost.localdomain localhost matrix

(yeah I know the hostname is matrix I just didnt feel like being creative)
and I know I am supposed to chang ethe last part which I guess is supposed to refer to the hostname, but even after changing that and a reboot the hostname has not changed. Could somebody please hlep change this? Thanks!

There are two simple things you can do to change your system's hostname.
First, use the hostname program, it can set the hostname as well as reading it.
Just type:
hostname mysystem.mydomain.com

That change is non-persistant though (it goes away when you reboot).
You can edit /etc/hostname to make that change permanant.

You can also change your hostname in "base-config" (you need to "su" to root first).

I was being stupid I guess. I forgot you could edit /etc/hostname, I kept thinking you culdnt edit a program or something. Thanks for the help!

You can also install the etherconf package. That will allow you to control the the host and network info with debconfig.
