Which TCP port is used by SSH?

SSH provides secure remote access over TCP, and by default it uses port 22. This default port lets clients know where to connect for a secure shell session, so administrators and firewalls can easily allow the traffic. The other commonly seen ports correspond to different services: port 21 is used for FTP control, port 23 for Telnet (an older, unencrypted remote login), and port 80 for HTTP web traffic. SSH can be configured to listen on a different port, but 22 is the standard, widely recognized port for secure remote login.
