fingerd(1M)
NAME
in.fingerd, fingerd - remote user information server
SYNOPSIS
/usr/sbin/in.fingerd
DESCRIPTION
fingerd implements the server side of the Name/Finger proto-
col, 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 con-
nected, 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.

NOTES
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 com-
mands received.
