  35 .Dt HUNTD 6
  36 .Sh NAME
  37 .Nm huntd
  38 .Nd hunt daemon, back-end for hunt game
  39 .Sh SYNOPSIS
  40 .Nm
  41 .Op Fl s
  42 .Op Fl p Ar port
  43 .Sh DESCRIPTION
  44 .Nm
  45 controls the multi-player
  46 .Xr hunt 6
  47 game.
  48 When it starts up, it tries to notify all members of the
  49 .Em hunt-players
  50 mailing list (see
  51 .Xr sendmail 8 )
  52 by faking a
  53 .Xr talk 1
  54 request from user
  55 .Dq Hunt Game .
  56 .Pp
  57 The
  58 .Fl s
  59 option is for running
  60 .Nm
  61 forever (server mode).
  62 This is similar to running it under the control of
  63 .Xr inetd 8
  64 (see below), but it consumes a process table entry when no one is playing.
  65 .Pp
  66 The
  67 .Fl p
  68 option changes the UDP port number used to rendezvous with the player
  69 process and thus allows for private games of hunt.
  70 This option turns off the notification of players on the
  71 .Em hunt-players
  72 mailing list.
  73 .Ss INETD
  74 To run
  75 .Nm
  76 from
  77 .Xr inetd 8 ,
  78 you'll need to
  79 .\"put the
  80 .\".Nm hunt
  81 .\"service in
  82 .\".Pa /etc/services :
  83 .\".Bd -literal
  84 .\"hunt 26740/udp               # multi-player/multi-host mazewars
  85 .\".Ed
  86 .\"and
  87 uncomment the following line in
  88 .Pa /etc/inetd.conf :
  89 .Bd -literal -offset indent -compact
  90 hunt dgram udp wait nobody /usr/games/huntd huntd
  91 .Ed
  92 Do not use any of the command line options; if you want
  93 .Xr inetd 8
  94 to start up
  95 .Nm
  96 on a private port, change the port listed for
  97 .Nm hunt
  98 in
  99 .Pa /etc/services .
 100 .Sh NETWORK RENDEZVOUS
 101 When
 102 .Xr hunt 6
 103 starts up, it broadcasts on the local area net
 104 (using the broadcast address for each interface) to find a
 105 .Nm hunt
 106 game in progress.
 107 If a
 108 .Nm
 109 hears the request, it sends back the port number for the
 110 .Nm hunt
 111 process to connect to.
 112 Otherwise, the
 113 .Nm hunt
 114 process starts up a
 115 .Nm
 116 on the local machine and tries to rendezvous with it.
