| 10 | fingerd \- remote user information server | |
| 11 | .SH SYNOPSIS | |
| 12 | .B /etc/fingerd | |
| 13 | .SH DESCRIPTION | |
| 14 | .I Fingerd | |
| 15 | is a simple protocol based on RFC742 that provides an interface to the | |
| 16 | Name and Finger programs at several network sites. | |
| 17 | The program is supposed to return a friendly, | |
| 18 | human-oriented status report on either the system at the moment | |
| 19 | or a particular person in depth. | |
| 20 | There is no required format and the | |
| 21 | protocol consists mostly of specifying a single ``command line''. | |
| 22 | .PP | |
| 23 | .I Fingerd | |
| 24 | listens for TCP requests at port 79. | |
| 25 | Once connected it reads a single command line | |
| 26 | terminated by a <CRLF> which is passed to | |
| 27 | .IR finger (1). | |
| 28 | .I Fingerd | |
| 29 | closes its connections as soon as the output is finished. | |
| 30 | .PP | |
| 31 | If the line is null (i.e. just a <CRLF> is sent) then | |
| 32 | .I finger | |
| 33 | returns a ``default'' report that lists all people logged into | |
| 34 | the system at that moment. | |
| 35 | .PP | |
| 36 | If a user name is specified (e.g. eric<CRLF>) then the | |
| 37 | response lists more extended information for only that particular user, | |
| 38 | whether logged in or not. | |
| 39 | Allowable ``names'' in the command line include both ``login names'' | |
| 40 | and ``user names''. | |
| 41 | If a name is ambiguous, all possible derivations are returned. | |
| 42 | .SH SEE ALSO | |

| 44 | .SH BUGS | |
| 45 | Connecting directly to the server from a TIP | |
| 46 | or an equally narrow-minded TELNET-protocol user program can result | |
| 47 | in meaningless attempts at option negotiation being sent to the | |
| 48 | server, which will foul up the command line interpretation. | |
| 49 | .I Fingerd | |
| 50 | should be taught to filter out IAC's and perhaps even respond | |
| 51 | negatively (IAC WON'T) to all option commands received. |
