[Lilux-help] telnet or ssh through coward firewalls

[Jay Christnach]

Especially the Windows-Sysadmins poor-sports tend to block everything 
they think isn't useful to the "normal" user with their clickorama 
firewalls. Why should they block an ssh outgoing connection?
It is possible to run an sshd or telnetd on a different port. So what 
well-known ports do you think are normally not blocked by the admins of 
universities and internetcafés? I thought of maybe IRC or something else 
  which people like to play with and would get angry if they couldn't. 
What do you think would be the best choice?
