| 12 | .Nm fingerd | |
| 13 | .Nd remote user information server | |
| 14 | .Sh SYNOPSIS | |
| 15 | .Nm fingerd | |
| 16 | .Sh DESCRIPTION | |
| 17 | .Nm Fingerd | |
| 18 | is a simple protocol based on | |
| 19 | .%T RFC742 | |
| 20 | that provides an interface to the | |
| e6b338bd KM |
21 | Name and Finger programs at several network sites. |
| 22 | The program is supposed to return a friendly, | |
| 23 | human-oriented status report on either the system at the moment | |
| 24 | or a particular person in depth. | |
| 25 | There is no required format and the | |
| 0fccfdb8 CL |
26 | protocol consists mostly of specifying a single |
| 27 | .Dq command line . | |
| 28 | .Pp | |
| 29 | .Nm Fingerd | |
| 30 | listens for | |
| 31 | .Tn TCP | |
| 32 | requests at port 79. | |
| e6b338bd | 33 | Once connected it reads a single command line |
| 0fccfdb8 CL |
34 | terminated by a |
| 35 | .Aq Tn CRLF | |
| 36 | which is passed to | |
| 37 | .Xr finger 1 . | |
| 38 | .Nm Fingerd | |
| e6b338bd | 39 | closes its connections as soon as the output is finished. |
| 0fccfdb8 CL |
40 | .Pp |
| 41 | If the line is null (i.e. just a | |
| 42 | .Aq Tn CRLF | |
| 43 | is sent) then | |
| 44 | .Xr finger | |
| 45 | returns a | |
| 46 | .Dq default | |
| 47 | report that lists all people logged into | |
| e6b338bd | 48 | the system at that moment. |
| 0fccfdb8 CL |
49 | .Pp |
| 50 | If a user name is specified (e.g. | |
| 51 | .Pf eric Aq Tn CRLF ) | |
| 52 | then the | |
| e6b338bd KM |
53 | response lists more extended information for only that particular user, |
| 54 | whether logged in or not. | |
| 0fccfdb8 CL |
55 | Allowable |
| 56 | .Dq names | |
| 57 | in the command line include both | |
| 58 | .Dq login names | |
| 59 | and | |
| 60 | .Dq user names . | |
| e6b338bd | 61 | If a name is ambiguous, all possible derivations are returned. |

| 63 | .Xr finger 1 | |
| 64 | .Sh BUGS | |
| 65 | Connecting directly to the server from a | |
| 66 | .Tn TIP | |
| 67 | or an equally narrow-minded | |
| 68 | .Tn TELNET Ns \-protocol | |
| 69 | user program can result | |
| e6b338bd KM |
70 | in meaningless attempts at option negotiation being sent to the |
| 71 | server, which will foul up the command line interpretation. | |
| 0fccfdb8 CL |
72 | .Nm Fingerd |
| 73 | should be taught to filter out | |
| 74 | .Tn IAC Ns \'s | |
| 75 | and perhaps even respond | |
| 76 | negatively | |
| 77 | .Pq Tn IAC WON'T | |
| 78 | to all option commands received. | |
