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