[Twisted-Python] ssh client and server

[cyli at alum.mit.edu]

If I understand you correctly, you want a shelless SSH server but one 
that executes commands.  For instance, it will accept the following 
connection:

ssh server "echo Hello!"

But not:

ssh server

Is this correct?  I'm did something similar, except that I also reject 
the first type of command.  What I did was to overwrite 
session.SSHSession's request_shell command to terminate the connection 
instead of returning a shell.    And then of course I subclassed 
ConchUser to return my own session (rather than session.SSHSession) for 
the channelLookup, and wrote my own realm that returned my user from 
requestAvatar.

There may be a better way to do it, but this is short, and it works. I 
stuck my code up here in case you want to look at it:
