[CentOS] ( SOLVED ) Hostname too long

Good day,

Some time ago I asked some assistance for the long hostname in the 
terminals.

Editing .bashrc in user and root by adding PS1=xxxxxxx did make the 
difference.

Here is something I picked up on another list that make editing .bashrc 
not necessary.
as root..    gedit /etc/sysconfig/network

# HOSTNAME=localhost.localdomain

change to in my case and that solves the problem

HOSTNAME=johan.jan

Johan
