Which port and protocol is used for SSH remote login?

Explanation:
SSH remote login uses port 22 over TCP. SSH (Secure Shell) provides encrypted, authenticated access to a remote system, which needs a reliable, ordered data stream—TCP delivers that. The other ports map to different services: port 23 is Telnet, an insecure alternative for remote login; port 25 is SMTP for email; port 53 is DNS, typically using UDP for queries (though DNS can use TCP in some cases). While SSH can be configured to run on a different port, the default and most common is 22 TCP.
