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.

FILES

       /var/adm/utmpx	       User and accounting information.

       /etc/passwd	       System password file.

       /var/adm/lastlog        Last login times.

       $HOME/.plan	       User's plans.

       $HOME/.project	       User's projects.

USAGE

       fingerd and in.fingerd are IPv6-enabled. See ip6(7P).

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(5), 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(1M). Responsibil-
       ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config-
       uration information for this service. The service's status can be queried using the svcs(1) command.
