The fingerd program allows users to get information about remote systems or users when they execute; for example, finger user@host.
The fingerd program is a protocol that provides an interface to the finger(1) command. fingerd is invoked by inetd(8), which listens for finger requests at port 79. When it receives control, fingerd reads a single command line, terminated by a newline, and passes it to the finger command, which generates a report. fingerd closes its port connection when output from finger is finished.
Commands: finger(1), inetd(8), syslogd(8), who(1)
