OpenSSH is a freely available version of the Secure Shell (SSH) protocol family of tools for remotely controlling, or transferring files between, computers.

Traditional tools used to accomplish these functions, such as telnet or rcp, are insecure and transmit the user's password in cleartext when used. OpenSSH provides a server daemon and client tools to facilitate secure, encrypted remote control and file transfer operations, effectively replacing the legacy tools. The OpenSSH server component, sshd, listens continuously for client connections from any of the client tools. When a connection request occurs, sshd sets up the correct connection depending on the type of client tool connecting. For example, if the remote computer is connecting with the ssh client application, the OpenSSH server sets up a remote control session after authentication.
If a remote user connects to an OpenSSH server with scp, the OpenSSH server daemon initiates a secure copy of files between the server and client after authentication. OpenSSH can use many authentication methods, including plain password, public key, and Kerberos tickets. • To set your OpenSSH to listen on TCP port 2222 instead of the default TCP port 22, change the Port directive as such: Port 2222 • To have sshd allow public key-based login credentials, simply add or modify the line: PubkeyAuthentication yes If the line is already present, then ensure it is not commented out. • To make your OpenSSH server display the contents of the /etc/issue.net file as a pre-login banner, simply add or modify the line: Banner /etc/issue.net In the /etc/ssh/sshd_config file.
