KNOPPIX changed HOSTNAME

I was testing out the new version of KNOPPIX since the electric went out in the neighborhood (California). After playing around in it, which is really neat, it changed my HOSTNAME and the command prompt. i.e. user@KNOPPIX> used to be user@IOS How do I go about changing it back? I checked the /etc/HOSTNAME, it is IOS.local, where else do I need to look? TIA! NeoFax
