Thanks for helping out, even on saturday night! (what kind of people are we? :-))
The above is clear, and I am connecting to moon## as root, but it asks for a password anyway..
As I have never entered a passwd in Kubuntu, I don't have one...
So what's the clue?
In the meantime did a ssh erwin@moon## and then login succeeded..
So i guess its a root pwd problem?
