in.fingerd(8)           System Administration Commands           in.fingerd(8)

NAME
       in.fingerd, fingerd - remote user information server

SYNOPSIS
       /usr/sbin/in.fingerd [-s]

DESCRIPTION
       fingerd  implements the server side of the Name/Finger protocol, speci‐
       fied 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  ex‐
       change  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 ar‐
       guments to finger(1), prepended with -s. fingerd closes its connections
       as soon as the output is finished.

OPTIONS
       fingerd supports the following option.

       -s    Enable secure mode. Deny forwarding of queries  to  other  remote
             hosts.


FILES
       /var/adm/utmpx      User and accounting information.


       /var/adm/lastlog    Last login times.


       $HOME/.plan         User's plans.


       $HOME/.project      User's projects.

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 com‐
       mand line interpretation. fingerd should be taught to filter out  IAC's
       and  perhaps  even respond negatively (IAC does not) to all option com‐
       mands 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.
