Which port is associated with the rlogin service?

Explanation:
Rlogin is a legacy remote login service that runs over TCP and listens on port 513. That specific port is the well-known assignment for rlogin, so a client connects to the rlogind daemon on port 513 to log in remotely. The other ports listed correspond to different services (for example, 23 is Telnet, 514 is rsh, and 111 is the RPC portmapper), which is why port 513 is the correct association for rlogin.
