[paramiko] Testing an exception

[Todd Whiteman]

Hi Jay,

You get this exception from connecting to a remote machine on a non-ssh 
port, so when Paramiko tries to read in the relevant SSH information, it 
fails and raises the SSHException you received.

A simple repro example is to try and connect to the ftp port (port 21) 
instead of the SSH port (port 22).

Cheers,
Todd
