<H2>DESCRIPTION</H2><PRE>
|
|
<STRONG>Fingerd</STRONG> 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''.
|
|
|
|
<STRONG>Fingerd</STRONG> listens for TCP requests at port 79. Once connected it reads a
|
|
single command line terminated by a <CRLF> which is passed to <STRONG><A HREF="../man1/finger.1.html">finger(1)</A></STRONG>.
|
|
<STRONG>Fingerd</STRONG> closes its connections as soon as the output is finished.
|
|
|
|
If the line is null (i.e. just a <CRLF> is sent) then <STRONG>finger</STRONG> 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.

<H2>BUGS</H2><PRE>
|
|
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. <STRONG>Fingerd</STRONG> should be taught to filter out IAC's and perhaps
|
|
even respond negatively (IAC WON'T) to all option commands received.
