System Administration Commands | in.fingerd(1M) |
| in.fingerd, fingerd - remote user information server |
SYNOPSIS
|
fingerd implements the server side of the Name/Finger
protocol, specified in RFC 742. The Name/Finger protocol
provides a remote interface to programs which display information on system
status and individual users. The protocol imposes little structure on the
format of the exchange between client and server. The client provides a
single command line to the finger server which returns a printable reply.
fingerd waits for connections on TCP port 79. Once connected, it reads a single command line terminated
by RETURN-LINEFEED and passes the arguments to finger(1), prepended with -s. fingerd closes its connections as soon as
the output is finished.
You must invoke fingerd from inetd.
See inetd(1M) for more information.

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 will not) to all
option commands received.
