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
Regards Johan
