This works nicely - thank you very much!

Nevertheless I tried to use ssh on the local mashine called MINI while
logged in as user "rland" and using one of the xterm's:

ssh -l root MINI

 - the system then prompts me for the password and I keyed the root
password. Reaction - "permission denied"

There must be something I had missed.

Doesn't this rely on the OS and the processor. Would one char be coded
by 8bits on the coming Intel 64bit processor and 64bit linux?
