.SH Syntax
.B /etc/fingerd
.SH Description
.NXR "fingerd program" 
The
.PN fingerd
program is a protocol that provides an interface to the
Name and Finger programs at several network sites.
The program returns an in depth 
status report on either the system currently in use 
or on a particular user whether that user is logged in or not.
.PP
The
.PN fingerd
program is never executed directly by a user, but rather by the
ULTRIX Internet listener daemon 
.PN /etc/inetd .
When 
.PN /etc/inetd 
is listening on port 79, it passes any requests
that it receives to 
.PN /etc/fingerd .  
Once 
.PN fingerd
receives control, it reads a
single command line terminated by a
.CT F
which is passed to 
.MS finger 1 .
The
.PN fingerd
command closes its connections as soon as the output is finished.
.PP
If the line is null, for example a 
.CT F 
is sent, then 
.PN finger
returns a default report that lists all the users logged into
the system at that moment.
.PP
If a user name is specified as 
.PN eric^F , 
for example, more extended information is listed for 
only that particular user, whether he is logged in or not.
Allowable names in the command line include both login names
and user names.
If a name is ambiguous, however, all possible derivations are returned.
