+.Sh NAME
+.Nm fingerd
+.Nd remote user information server
+.Sh SYNOPSIS
+.Nm fingerd
+.Op Fl wulf
+.Op Fl pL Ar path
+.Op Fl t Ar timeout
+.Sh DESCRIPTION
+.Nm Fingerd
+is a simple daemon based on
+.%T RFC1196
+that provides an interface to the
+.Dq finger
+program at most 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. 
+.Pp
+If the
+.Fl w
+option is given, remote users will get an additional 
+.Dq Welcome to ...
+banner
+which also shows some informations (e.g. uptime, operating system name and
+release) about the system the
+.Nm fingerd
+is running on. Some sites may consider this a security risk as it
+gives out information that may be useful to crackers. 
+.Pp
+If the 
+.Fl u
+option is given, requests of the form
+.Dq finger @host
+are rejected.
+.Pp
+If the
+.Fl l
+option is given, information about requests made is logged. This
+option probably violates users' privacy and should not be used on
+multiuser boxes.
+.Pp
+If the
+.Fl f
+option is given, finger forwarding (user@host1@host2) is allowed.
+Useful behind firewalls, but probably not wise for security and
+resource reasons.
+.Pp
+The 
+.Fl p
+option allows specification of an alternate location for fingerd to find
+the 
+.Dq finger
+program. The
+.Fl L
+option is equivalent.
+.Pp
+The
+.Fl t
+option specifies the time to wait for a request before closing the
+connection.  A value of 0 waits forever.  The default is 60 seconds.
+.Pp
+Options to fingerd should be specified in 
+.Pa /etc/inetd.conf .
+.Pp
+The finger protocol consists mostly of specifying command arguments.
+The 
+.Xr inetd 8
+.Dq super-server
+runs
+.Nm fingerd
+for 
+.Tn TCP
+requests received on port 79.
+Once connected 
+.Nm fingerd
+reads a single command line
+terminated by a
+.Aq Tn CRLF
+which is passed to
+.Xr finger 1 .
+It closes its connections as soon as all output is finished.
+.Pp
+If the line is empty (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. This feature is blocked by the 
+.Fl u
+option.
+.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.
+.Sh SEE ALSO
+.Xr finger 1 ,
+.Xr inetd 8
+.Sh RESTRICTIONS
+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.
+.Sh HISTORY
+The finger daemon appeared in
+.Bx 4.3 .
