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.
