+.Sh NAME
+.Nm fingerd
+.Nd remote user information server
+.Sh SYNOPSIS
+.Nm fingerd
+.Op Fl s
+.Op Fl l
+.Op Fl p Ar filename
+.Sh DESCRIPTION
+.Nm Fingerd
+is a simple protocol based on
+.%T RFC1196
+that provides an interface to the
+Name and Finger programs at several network sites.
+The program is supposed to return a friendly,
+human-oriented status report on either the system at the moment
+or a particular person in depth.
+There is no required format and the
+protocol consists mostly of specifying a single
+.Dq command line .
+.Pp
+.Nm Fingerd
+listens for
+.Tn TCP
+requests at port 79.
+Once connected it reads a single command line
+terminated by a
+.Aq Tn CRLF
+which is passed to
+.Xr finger 1 .
+.Nm Fingerd
+closes its connections as soon as the output is finished.
+.Pp
+If the line is null (i.e. just a
+.Aq Tn CRLF
+is sent) then
+.Xr finger
+returns a
+.Dq default
+report that lists all people logged into
+the system at that moment.
+.Pp
+If a user name is specified (e.g.
+.Pf eric Aq Tn CRLF )
+then the
+response lists more extended information for only that particular user,
+whether logged in or not.
+Allowable
+.Dq names
+in the command line include both
+.Dq login names
+and
+.Dq user names .
+If a name is ambiguous, all possible derivations are returned.
+.Pp
+The following options may be passed to
+.Nm fingerd
+as server program arguments in
+.Pa /etc/inetd.conf :
+.Bl -tag -width Ds
+.It Fl s
+Enable secure mode.
+Queries without a user name are rejected and
+forwarding of queries to other remote hosts is denied.
+.It Fl l
+Enable logging.
+The name of the host originating the query is reported via
+.Xr syslog 3
+at LOG_NOTICE priority.
+.It Fl p
+Use an alternate program as the local information provider.
+The default local program
+executed by
+.Nm fingerd
+is
+.Xr finger 1 .
+By specifying a customized local server,
+this option allows a system manager
+to have more control over what information is
+provided to remote sites.
+.El
+.Sh SEE ALSO
+.Xr finger 1
+.Sh BUGS
+Connecting directly to the server from a
+.Tn TIP
+or an equally narrow-minded
+.Tn TELNET Ns \-protocol
+user program can result
+in meaningless attempts at option negotiation being sent to the
+server, which will foul up the command line interpretation.
+.Nm Fingerd
+should be taught to filter out
+.Tn IAC Ns \'s
+and perhaps even respond
+negatively
+.Pq Tn IAC WON'T
+to all option commands received.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.3 .
