What is SSH used for?

Usage. SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections; it can transfer files using the associated SSH file transfer (SFTP) or secure copy (SCP) protocols. SSH uses the client-server model.

How does SSH key authentication work?

The way SSH works is by making use of a client-server model to allow for authentication of two remote systems and encryption of the data that passes between them. It organizes the secure connection by authenticating the client and opening the correct shell environment if the verification is successful.

Why do network admins use SSH port forwarding?

Port forwarding is a general TCP proxying feature that tunnels TCP connections through an SSH session. It is useful for securing protocols that may not be secure and tunneling through to TCP connections that may be blocked by firewalls. It so happens that FTP opens random ports on a client after authentication.
