IN.FINGERD(8) Maintenance Procedures IN.FINGERD(8)

NAME

in.fingerd, fingerd - remote user information server

SYNOPSIS

/usr/sbin/in.fingerd

DESCRIPTION

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.

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 foul up the command line
interpretation. fingerd should be taught to filter out IAC's and perhaps
even respond negatively (IAC does not) to all option commands received.


The in.fingerd service is managed by the service management facility,
smf(7), under the service identifier:

svc:/network/finger:default


Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(8). Responsibility for
initiating and restarting this service is delegated to inetd(8). Use
inetadm(8) to make configuration changes and to view configuration
information for this service. The service's status can be queried using
the svcs(1) command.
