- NAME
- in.fingerd --- remote user information server
-
- SYNOPSIS
- in.fingerd file
-
- 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 is started by inetd when it receives a TCP connection
- request at port 79. Once connected it reads a single command
- line terminated by a <CRLF> which is passed to finger.
- 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, file given as its argument.
-
- If a user name is specified (e.g. eric<CRLF>) then the
- response lists more extended information for that particular
- user, whether logged in or not. Allowable `names' in the
- command line include both `login names' and `user names'.
-
- SEE ALSO
- finger

- 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.
-
- fingerd requires the APipe handler installed and mounted in
- the system for correct operation.
