fingerd

FINGERD(8)						    BSD System Manager's Manual 						FINGERD(8)

NAME

     fingerd -- remote user information server

SYNOPSIS

     fingerd [-wulf] [-pL path] [-t timeout]

DESCRIPTION

     Fingerd is a simple daemon based on RFC1196 that provides an interface to the ``finger'' program at most network sites.  The program is sup-
     posed to return a friendly, human-oriented status report on either the system at the moment or a particular person in depth.

     If the -w option is given, remote users will get an additional ``Welcome to ...'' banner which also shows some informations (e.g. uptime,
     operating system name and release) about the system the fingerd is running on. Some sites may consider this a security risk as it gives out
     information that may be useful to crackers.

     If the -u option is given, requests of the form ``finger @host'' are rejected.

     If the -l option is given, information about requests made is logged. This option probably violates users' privacy and should not be used on
     multiuser boxes.

     If the -f option is given, finger forwarding (user@host1@host2) is allowed.  Useful behind firewalls, but probably not wise for security and
     resource reasons.

     The -p option allows specification of an alternate location for fingerd to find the ``finger'' program. The -L option is equivalent.

     The -t option specifies the time to wait for a request before closing the connection.  A value of 0 waits forever.  The default is 60 sec-
     onds.

     Options to fingerd should be specified in /etc/xinetd.d/finger.

     The finger protocol consists mostly of specifying command arguments.  The xinetd(8) ``super-server'' runs fingerd for TCP requests received
     on port 79.  Once connected fingerd reads a single command line terminated by a <CRLF> which is passed to finger(1).  It closes its connec-
     tions as soon as all output is finished.

     If the line is empty (i.e. just a <CRLF> is sent) then finger returns a ``default'' report that lists all people logged into the system at
     that moment. This feature is blocked by the -u option.

     If a user name is specified (e.g.	eric<CRLF>) then the response lists more extended information for only that particular user, whether
     logged in or not.	Allowable ``names'' in the command line include both ``login names'' and ``user names''.  If a name is ambiguous, all pos-
     sible derivations are returned.

SEE ALSO

     finger(1), xinetd(8)

RESTRICTIONS

     Connecting directly to the server from a TIP or an equally narrow-minded TELNET-protocol user program can result in meaningless attempts at
     option negotiation being sent to the server, which will foul up the command line interpretation.

HISTORY

     The finger daemon appeared in 4.3BSD.
