Secure Shell is a set of programs for logging into a remote machine and for
executing commands on a remote machine.  It is intended to replace rlogin,
rsh, rcp, etc. 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.

OpenSSH is a version of Secure Shell based upon a much less encumbered
SSH version 1.2.12, which has a BSD-style license.  Maintained by the
OpenBSD project, this is the most free and secure SSH implementation
in the world.  OpenSSH supports SSH protocol version 1.5 and 2.0.
