.SH USAGE
If you are just an ordinary user and efingerd is already installed by your
friendly administrator, you can take the advantage of it by making
executable .efingerd in your home directory (it can be anything - from
single shell script to a program in super-hyper-extra-object oriented
language - only speed makes a difference). This program takes two
arguments, the first is the name of remote user fingering you (or (null)
if his/her/its system does not run ident), the second one is address of
his computer (or ip number, if efingerd is installed with option -n).
Standard output of this program is then displayed to the person fingering
you. Look at examples/.efingerd for a nice example.
Following executables are providing information about your machine to the
fingerer:
/etc/efingerd/list
what to display when somebody does finger @your.machine
/etc/efingerd/luser
what to display when somebody fingers user on your machine, and
the fingered user does not have ~/.efingerd file
/etc/efingerd/nouser
what to display when somebody fingers non-existent user on your machine
If the local user has file .efingerd in his/her/its home directory, and it is
readable by the daemon, it
will be executed and it's output will be served to the fingerer.
These are normal programs, displaying on standard output desired
information. These programs are called with following parameters:
$1 - identity of remote user, (null) if his/her/its system is not running
ident
$2 - address of remote machine (IP number if it has not reverse DNS
entry or you specified -n)
$3 - name of local user being fingered
Look at examples/ for examples.
Don't forget that these programs must be executable by efingerd daemon.
