Description : SSH (Secure SHell) is a program for logging into and executing
: commands on a remote machine. SSH is intended to replace rlogin and
: rsh, and to 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 OpenBSD’s version of the last free version of SSH, bringing
: it up to date in terms of security and features.
:
: This package includes the core files necessary for both the OpenSSH
: client and server. To make this package useful, you should also
: install openssh-clients, openssh-server, or both.
