.Dt HUNTD 6
|
|
.Sh NAME
|
|
.Nm huntd
|
|
.Nd hunt daemon, back-end for hunt game
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl s
|
|
.Op Fl p Ar port
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
controls the multi-player
|
|
.Xr hunt 6
|
|
game.
|
|
When it starts up, it tries to notify all members of the
|
|
.Em hunt-players
|
|
mailing list (see
|
|
.Xr sendmail 8 )
|
|
by faking a
|
|
.Xr talk 1
|
|
request from user
|
|
.Dq Hunt 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.
|
|
.Pp
|
|
The
|
|
.Fl p
|
|
option changes the UDP port number used to rendezvous with the player
|
|
process and thus allows for private games of hunt.
|
|
This option turns off the notification of players on the
|
|
.Em hunt-players
|
|
mailing list.
|
|
.Ss INETD
|
|
To run
|
|
.Nm
|
|
from
|
|
.Xr inetd 8 ,
|
|
you'll need to
|
|
put the
|
|
.Nm hunt
|
|
service in
|
|
.Pa /etc/services :
|
|
.Bd -literal
|
|
hunt 26740/udp # multi-player/multi-host mazewars
|
|
.Ed
|
|
and
|
|
add the following line to
|
|
.Pa /etc/inetd.conf :
|
|
.Bd -literal -offset indent -compact
|
|
hunt dgram udp wait nobody @sbindir@/huntd huntd
|
|
.Ed
|
|
Do not use any of the command line options; if you want
|
|
.Xr inetd 8
|
|
to start up
|
|
.Nm
|
|
on a private port, change the port listed for
|
|
.Nm hunt
|
|
in
|
|
.Pa /etc/services .
|
|
.Sh NETWORK RENDEZVOUS
|
|
When
|
|
.Xr hunt 6
|
|
starts up, it broadcasts on the local area net
|
|
(using the broadcast address for each interface) to find a
|
|
.Nm hunt
|
|
game in progress.
|
|
If a
|
|
.Nm
|
|
hears the request, it sends back the port number for the
|
|
.Nm hunt
|
|
process to connect to.
|
|
Otherwise, the
|
|
.Nm hunt
|
|
process starts up a
|
|
.Nm
|
|
on the local machine and tries to rendezvous with it.
