NAME

huntd —

hunt daemon, back-end for hunt game

SYNOPSIS

huntd [-s] [-a addr] [-Dvar = value ...] [-p port]

DESCRIPTION

huntd controls the multi-player hunt(6) game.

The -a addr option is used to cause the server to listen only on a specific interface address. The addr argument must be given as an IP address.

Options given with -D override those read from configuration files (see CONFIGURATION, below).

The -p port option changes the UDP port number used to rendezvous with the player process and thus allows for private games of hunt(6).

The -s option is for running huntd forever (server mode). This is similar to running it under the control of inetd(8) (see below), but it consumes a process table entry when no one is playing, and monitor clients are not disconnected.

INETD

To run huntd from inetd(8), you'll need to add this line to /etc/inetd.conf:

hunt dgram udp wait nobody
  /usr/local/bin/huntd HUNT

Do not use any of the command line options — if you want inetd(8) to start up huntd on a private port, change the port listed in /etc/services.

NETWORK RENDEZVOUS

When hunt(6) starts up, it broadcasts on attached networks, using the broadcast or point-to-point destination address for each interface, to find a hunt game in progress. If a huntd hears the request, it sends back the port number for the hunt process to connect to.

Regardless of how huntd is started, it always checks incoming connections with hosts_access(5), using a service name of ‘huntd’.

CONFIGURATION

When huntd starts, it looks for configuration files that determine game parameters. Each line of a configuration file is of the form var = value. Comments start with a hash sign (‘#’). The configuration files loaded in order (if they exist) are: /etc/hunt.conf, $HOME/.hunt.conf, and ./.hunt.conf.

Many of these variables require intimate knowledge of the driver source code. The complete list of configurable variables is as follows.

random: enable dispersion doors (default 1)
reflect: enable generation of reflection walls (default 1)
monitor: enable monitors (default 1)
ooze: enable slime shots (default 1)
fly: enable flight (default 1)
volcano: enable volcanoes (default 1)
drone: enable drone (default 1)
boots: enable boots (default 1)
scan: enable scanning (default 1)
cloak: enable cloaking (default 1)
logerr: errors to stderr (default 1)
syslog: errors to syslogd(8) (default 0)
scoredecay: nr deaths before nr kills begins to decay (default 15)
maxremove: Maximum number of holes in the maze wall (default 40)
linger: Seconds to keep game open with no players. -1 means forever (default 90)
flytime: max time flying (default 20)
flystep: max displacement each flying time unit (default 5)
volcano_max: max size of volcano (default 50)
ptrip_face: percentage chance of tripping a grenade on pickup (default 2)
ptrip_back: percentage chance of same when backing onto it (default 95)
ptrip_side: percentage chance of same when walking sideways into it (default 50)
prandom: percentage of time dispersion doors appear (default 1)
preflect: percentage of time reflection walls appear (default 1)
pshot_coll: percentage chance of shots colliding (default 5)
pgren_coll: percentage chance of grenades colliding (default 10)
pgren_catch: facing player chance of catching grenade (default 10)
pmiss: percentage chance of bullet missing player (default 5)
pdroneabsorb: percentage chance of absorbing a drone (default 1)
fall_frac: divisor of damage used for fall damage (default 5)
bulspd: speed of bullets (default 5)
ishots: initial ammo for player (default 15)
nshots: ammo boost for all when new player joins (default 5)
maxncshot: max number of simultaneous shots per player (default 2)
maxdam: the initial shield for each player (default 10)
mindam: minimum damage from one unit of ammo (default 5)
stabdam: damage from stabbing (default 2)
killgain: shield gained from killing someone (default 2)
slimefactor: charge multiplier for slime (default 3)
slimespeed: speed of slime (default 5)
lavaspeed: speed of volcano lava (default 1)
cloaklen: duration of a cloak (default 20)
scanlen: duration of a scan (default 20)
mindshot: minimum shot class needed to make a drone (default 2)
simstep: maximum simulation step in microseconds. Zero means traditional blocking behaviour. Try 55000 for something reasonable (default 0)
