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