.Sh NAME
.Nm huntd
.Nd hunt daemon, back-end for hunt game
.Sh SYNOPSIS
.Nm huntd
.Op Fl s
.Op Fl p Ar port
.Op Fl a Ar addr
.Oo
.Fl D Ns Ar var Ns = Ns value ...
.Oc
.Sh DESCRIPTION
.Nm
controls the multi-player
.Xr hunt 6
game.
.Pp
The
.Fl s
option is for running
.Nm
forever (server mode).
This is similar to running it under the control of
.Xr inetd 8
(see below),
but it consumes a process table entry when no one is playing,
and monitor clients are not disconnected.
.Pp
The
.Fl p Ar port
option changes the UDP port number used to rendezvous with the player
process and thus allows for private games of
.Xr hunt 6 .
.Pp
The
.Fl a Ar addr
option is used to cause the server to listen only on a 
specific interface address.
The
.Ar addr
argument must be given as an IP address.
.Pp
Options given with
.Fl D
override those read from configuration files (see
.Sx CONFIGURATION ,
below).
.Ss INETD
To run
.Nm
from
.Xr inetd 8 ,
you'll need to 
add this line to
.Pa /etc/inetd.conf :
.Pp
.Dl hunt dgram udp wait nobody /usr/games/huntd HUNT
.Pp
Do not use any of the command line options \(em if you want
.Xr inetd 8
to start up
.Nm huntd
on a private port, change the port listed in
.Pa /etc/services .
.Ss "NETWORK RENDEZVOUS"
When
.Xr hunt 6
starts up, it broadcasts on attached networks
(using the broadcast or point-to-point destination address for each interface)
to find a
.Nm hunt
game in progress.
If a
.Nm huntd
hears the request, it sends back the port number for the
.Nm hunt
process to connect to.
.Pp
Regardless of how
.Nm
is started, it always checks incoming connections with
.Xr host_access 5 ,
using a service name of
.Sq huntd .
.Ss "CONFIGURATION"
When
.Nm
starts, it looks for configuration files that determine
game parameters.
Each line of a configuration file is of the form
.Ar var No = Ar value .
Comments start with a hash sign (`#').
The configuration files loaded in order (if they exist) are:
.Pa /etc/hunt.conf ,
.Pa "$HOME/.hunt.conf" ,
and
.Pa ./.hunt.conf .
.Pp
Many of these variables require intimate knowledge of the
driver source code.
The complete list of configurable variables is as follows.
