[Lilux-help] telnet or ssh through coward firewalls

[Jay Christnach]

I don't want to have to stop another service like http,smtp,ftp,pop3, so 
So I'm looking for another port that is most likely to work from any site.
A second requirement is that I don't need to install software on the 
client side because they won't let me. (except for the ssh/telnet client 
putty which is a simple executable which doesn't kneed to be 
"installed"). A solution would be a java based thing like what Patrick 
Lemmers suggested.
Perhaps there is also a way to encapsulate ssh into http, but what would 
I have to run on the http-server to accomplish this?
I'm thinking of a php script with login that would activate/deactivate a 
sshd on a different port than normal and set/unset iptables rules 
accordingly. But which port to use if I don't want to sacrifice http or 
ftp etc.? As a last resort I would shut down ftpd and start sshd on port 
21.
What about nntp (119)? I guess this could be a good one.
