Senses
(I)
A client-server Internet protocol [R1413] for learning the identity of a user of a particular TCP connection.
Tutorial: Given a TCP port number pair, the server returns a character string that identifies the owner of that connection on the server's system. The protocol does not provide an authentication service and is not intended for authorization or access control. At best, it provides additional auditing information with respect to TCP.
