Description: secure shell (SSH) server, for secure access from 
remote machines
This is the portable version of OpenSSH, a free implementation of
the Secure Shell protocol as specified by the IETF secsh working
Ssh (Secure Shell) is a program for logging into a remote machine
and for executing commands on a remote machine.
It provides 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.
It can be used to provide applications with a secure communication
 This package provides the sshd server.
 In some countries it may be illegal to use any encryption at all
 without a special permit.
 sshd replaces the insecure rshd program, which is obsolete for most
