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 can be either a pathname, in which case a local socket by that name is used for the game, or a number, in which case it selects an alternate port number for the internet socket used for the game. This allows for private games of hunt. .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 uncomment the following line in .Pa /etc/inetd.conf : .Bd -literal -offset indent -compact hunt dgram udp wait nobody /usr/games/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. .Sh SEE ALSO .Xr sendmail 1 , .Xr hunt 6 .Sh AUTHORS Conrad Huang, Ken Arnold, and Greg Couch; .br University of California, San Francisco, Computer Graphics Lab
