   into, and executing commands on, a remote computer.  ssh is
   intended to replace {rlogin} and {rsh}, and provide secure
   encrypted communications between two untrusted hosts over an
   insecure network.  {X11} connections and arbitrary {TCP/IP}
   {ports} can also be forwarded over the secure channel.
