3 Hunt is a multi-player search-and-destroy game that takes place
4 in a maze. The game may either be slow and strategic or fast
5 and tactical, depending on how familiar the players are with the
10 Hunt is part of the user-contributed software distributed by
11 Berkeley in 4BSD. The sources are copyrighted by the authors
12 and the University of California. You may redistribute freely
13 as long as the copyright notices are retained.
17 hunt uses the socket mechanism of 4BSD Unix, so if you are on
18 System V (my sympathies), you're on your own.
19 If your machine does not permit non-setuid-root processes to
20 broadcast UDP packets, then hunt uses a *very* inefficient
21 method for locating the hunt server: it sends a packet
22 to every host on your network. If your machine falls
23 into this category, we strongly recommend that you use
24 either standalone or inetd mode *and* start hunt by
25 specifying the hunt server host.
26 hunt can be configured to use Unix-domain sockets, but that
27 code has not been tested in recent memory. Also, since
28 4.2BSD Unix-domain sockets are buggy, running hunt on
29 4.2BSD with Unix-domain sockets will probably crash
30 your system. If you want to experiment, feel free to
31 do so. However, don't say I didn't warn you :-).
32 hunt uses a fair amount of CPU time, both in user time (for
33 computing interactions) and system time (for processing
34 terminal interrupts). We found that a VAX 750 can
35 support about three users before the system is
36 noticeably impacted. The number goes up to about 8 or
37 10 for a VAX 8650. On a network of Sun 3/50's with the
38 server running on a 3/280, things work much more
39 smoothly as the computing load is distributed across
41 hunt may be dangerous to your health. "Arthritic pain" and
42 "lack of circulation" in fingers have been reported by
43 hunt abusers. Hunt may also be addictive, and the
44 withdrawal symptoms are not pretty :-)
48 1. Edit file "Makefile" and make sure the options selected are
49 reasonable. There are four "make" variables that you
50 should check: GAME_PARAM, SYSCFLAGS, SYSLDFLAGS, and DEFS.
51 GAME_PARAM controls what features of the game will be
52 compiled in (e.g. reflecting walls). The optional features
53 are listed in comments above where GAME_PARAM is defined.
54 If you want to try them, just add the ones you want to the
55 GAME_PARAM definition.
57 DEFS is where most system configuration is described.
58 If your system is 4.3BSD, Sun, Ultrix, Convex, HPUX
59 v6.0.1, or SGI, you're in luck. We provide the
60 appropriate definitions for these systems and you just
61 need to select one of them (e.g. if you have an Ultrix
62 system, just change the line
63 DEFS= $(GAME_PARAM) $(DEFS_43)
65 DEFS= $(GAME_PARAM) $(DEFS_ULTRIX)
66 ). If your system is *not* listed above, then you may
67 need to do some experiments. All of the options are
68 documented in the Makefile, be brave.
70 SYSCFLAGS and SYSLDFLAGS are used for "unusual" systems
71 and you probably won't need to deal with it. An
72 example of an unusual system is the Silicon Graphics
73 IRIS, which keeps the network socket code in a BSD
74 emulation library that is in -lbsd. Edit these only if
75 you *know* your system is "different."
77 2. Edit file "Makefile" and look at the "install:" target. By
78 default, files are installed in /usr/games,
79 /usr/games/lib, and /usr/man/man6, which are "standard"
80 locations for games. If your system has a local games
81 directory, you'll need to change these.
82 3. Edit file "pathname.c" and make sure the file names and port
83 numbers are reasonable. You can ignore the first set
84 of variables as they are used only for debugging
85 purposes. The second set is used in the installed
86 version of hunt. The important variables are "Driver"
87 (where the server is kept), "Test_port" (the Internet
88 UDP port number that new players should use to contact
89 the server), and "Stat_file" (where scoring statistics
90 and body counts are written). The only tricky variable
91 here is "Test_port". The default value is chosen so
92 that it is unlikely to conflict with other service port
93 numbers, but you can change it if you want to.
94 4. Type "make install", which will compile and install the
95 programs and manual pages. Now you're almost ready to
96 go (see next section). There may be some warnings during
97 compilation. Ignore them.
99 Setting up the network:
101 Hunt may be set up in one of three modes: standalone, inetd, or
102 nothing. In "standalone" mode, there is always a hunt server
103 running on a server machine. All players who enter the game
104 will be talking to this server. This is the mode we use at
105 UCSF. The cost is one entry in the process table on the server
106 machine. In "inetd" mode, the server is started via inetd.
107 Again, only one machine should be set up to answer game
108 requests. The cost is having to edit a few system files. In
109 "nothing" mode, no server is running when there is no one
110 playing. The first person to enter hunt will automatically
111 start up a server on his machine. This, of course, gives him
112 an unfair advantage. Also, there may be race conditions such
113 that players end up in different games. The choice of which
114 mode to use depends on site configuration and politics. We
115 recommend using "standalone" mode because it is simple to set
116 up and starts up rapidly.
120 FOR STANDALONE MODE, put these lines in /etc/rc.local on the
121 server machine. THERE SHOULD ONLY BE ONE SERVER MACHINE!
123 # start up the hunt daemon if present
124 if [ -f /usr/games/lib/huntd ]; then
125 /usr/games/lib/huntd -s & (echo -n ' huntd') >/dev/console
128 Also, you should start one up (on the off chance that you will
129 want to test this mess :-) by typing "/usr/games/lib/hunt -s".
133 FOR INETD MODE, then things get more complicated. You need to
134 edit both /etc/services and /etc/inetd.conf. In /etc/services,
139 26740 corresponds to the default "Test_port". If you changed
140 that variable, then you should put whatever value you used here
141 as well. In /etc/inetd.conf, add the line
143 hunt dgram udp wait nobody /usr/games/lib/huntd huntd
145 This works for 4.3BSD. I don't remember the configuration file
146 format for 4.2BSD inetd.
148 See the huntd.6 manual page for more details.
152 FOR NOTHING MODE, do nothing.
155 Now you are ready to test the code. Type "/usr/games/hunt" or
156 whatever you call the hunt executable. You should be prompted
157 for your name and team. Then you should get the display of a
158 maze. At this point, you should read the manual page :-).
162 Hunt is not officially supported by anyone anywhere (that I know of);
163 however, bug reports will be read and bug fixes/enhancements may be
164 sent out at irregular intervals. Send no flames, just money. Happy
173 P.S. The authors of the game want to emphasize that this version of hunt
174 was started over eight years ago, and the programming style exhibited here
175 in no way reflects the current programming practices of the authors.
