ol� Thorsten,

I didn't quite follow your ssh quest :-) but have you tried to isolate
the fault? if you havent done so yet, you can perhaps bring a linux box
in and use it as a client to make sure the server works (and revert the
process for the client). best use the same ip addresses as well...

good luck!
