ssh — OpenSSH SSH client (remote login program)

ssh (SSH client) is a program for logging into a remote machine and for executing commands on a remote machine. It is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an inse‐
cure network. X11 connections and arbitrary TCP ports can also be forwarded over the secure channel.
