Well, the overall difference to, lets say Debian is, that I seemingly
have no option to stealth this daemon. Of cause it will not allow any
connections from the net, but at least it signals that there is a
maschine running.
No clue if this a welcomely prerequisite to  try to break in.
Essentially I would like to be completely stealthed to the net, so no
one should be enabled to give rise to any reasoning for an attack!
I'd rather prefer not to deal with situations like this!


Thanks for response
