RFC 1196: Finger User Information Protocol, D.P. Zimmerman1990-12-01T23:00:00-00:00This memo describes the Finger User Information Protocol. This is a simple protocol which provides an interface to a remote user information program. Based on RFC 742, a description of the original Finger protocol, this memo attempts to clarify the expected communication between the two ends of a Finger connection. It also tries not to invalidate the many existing implementations or add unnecessary restrictions to the original protocol definition. This edition corrects and clarifies in a minor way, RFC 1194.
