NAME
|
|
fingerd, in.fingerd - remote user information server
|
|
|
|
SYNOPSIS
|
|
finger stream tcp nowait nobody /usr/sbin/in.fingerd in.fingerd
|
|
tcpd finger /usr/sbin/in.fingerd in.fingerd
|
|
|
|
DESCRIPTION
|
|
Fingerd is a simple protocol based on RFC742 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
|
|
``command line''.
|
|
|
|
Fingerd listens for TCP requests at port 79. Once connected it reads a
|
|
single command line terminated by a <CRLF> which is passed to finger(1).
|
|
Fingerd closes its connections as soon as the output is finished.
|
|
|
|
If the line is null (i.e. just a <CRLF> is sent) then finger returns a
|
|
``default'' report that lists all people logged into the system at that
|
|
moment.
|
|
|
|
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 possible
|
|
derivations are returned.
|
|
|
|

BUGS
|
|
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. Fingerd should be taught to filter out IAC's and perhaps
|
|
even respond negatively (IAC WON'T) to all option commands received.
