sudo apt-get install ssh
secure shell client and server (metapackage)
This metapackage is a convenient way to install both the OpenSSH client
and the OpenSSH server. It provides nothing in and of itself, so you
may remove it if nothing depends on it.
sudo apt-get install openssh-server
secure shell server, an rshd replacement
This is the portable version of OpenSSH, a free implementation of
the Secure Shell protocol as specified by the IETF secsh working
group.
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 is intended as a replacement for rlogin, rsh and rcp, and can be
used to provide applications with a secure communication channel.
This package provides the sshd server.
In some countries it may be illegal to use any encryption at all
without a special permit.
