26 Freeciv is a free turn-based multiplayer strategy game, in which each
27 player becomes the leader of a civilization, fighting to obtain the ul‐
28 timate goal: To become the greatest civilization.
29 Players of Civilization II® by Microprose® should feel at home, since
31 one aim of Freeciv is to have compatible rules.
32 Freeciv is maintained by an international team of coders and enthusi‐
34 asts, and is easily one of the most fun and addictive network games out
35 there!
36 This is the server program used to establish a Freeciv server - see
38 also freeciv-client(6) .
39 This manual page only lists the command line arguments. For details of
41 the directives necessary to configure freeciv-server see the Server
42 Manual which can be found at the Freeciv website
43 ⟨https://www.freeciv.org/⟩ as well as the documentation which is part
44 of the Freeciv distribution.
45
47 The following options are accepted on the command line of the server.
48 They may not be combined; that is, "freeciv-server -fp savegame.sav
49 5557" will not work, instead you would need to enter "freeciv-server -f
50 savegame.sav -p 5557". Most options have a short form (single hyphen
51 and single letter) and a long form (double hyphen and a complete word);
52 their effects are identical.
53 -A protocol, --Announce protocol
55 Uses protocol when announcing game in LAN. Possible values for
56 protocol are:
57 IPv4
59 IPv6
61 none
63 -a, --auth
66 Enables server authentication and allows access to registered
67 players only. Requires the --Database option to be specified.
68 -b address, --bind address
70 Sets the address on which the server will listen for clients.
71 -B address, --Bind-meta address
73 Sets the address which request to metaserver are sent from. De‐
74 faults to address given by -b option.
75 -d level, --debug level
77 Sets the amount of debugging information to be logged in the
78 file named by the -l option. Acceptable values for the
79 level_number are:
80 fatal for fatal messages only.
82 error for fatal and error messages.
84 normal for fatal, error and normal messages (default).
86 verbose for fatal, error, normal, and verbose messages.
88 -D filename, --Database filename
91 Specifies a database configuration file for authentication. This
92 file specifies the details of the database. See README.fcdb in
93 the Freeciv distribution for details of its format.
94 -e, --exit-on-end
96 When a game ends, exit instead of restarting.
97 -F [ signal_number ], --Fatal [ signal_number ]
99 Raise a custom signal on failed assertion. If signal_number is
100 not specified, then the ABRT signal will be used.
101 -f filename, --file filename
103 Loads a saved game (filename) into the server before initializa‐
104 tion, instead of starting a new game. This is for reloading
105 saved games, or for loading scenarios. See ENVIRONMENT for where
106 the server looks for these files.
107 The distribution comes with several scenarios, typically stored
109 in /usr/local/share/freeciv/scenarios, for example:
110 • british-isles-85x80-v2.80.sav
113 • earth-160x90-v2.sav
115 • earth-80x50-v3.sav
117 • europe-200x100-v2.sav
119 • hagworld-120x60-v1.2.sav
121 • iberian-peninsula-136x100-v1.0.sav
123 -G, --Guests
126 Allow guests to login as 'guest' when authentication is enabled.
127 -h, --help
129 Prints out a description of the command line options and exits.
130 -i address, --identity address
132 Reports the address to the metaserver. Then, the metaserver
133 will use this address to redirect the users.
134 -L module, --LoadAI module
136 Loads AI module. This option can appear multiple times to load
137 different modules.
138 -l filename, --log filename
140 Defines a log file, filename, to be produced during processing.
141 Use the -d option to set how much is logged. By default, fatal,
142 error, and normal messages are printed to standard output. With
143 a log file, such messages go to the log instead. If filename
144 already exists, it is appended to.
145 -M address, --Metaserver address
147 Specifies the address of the metaserver to send your server's
148 information to. By default, the standard metaserver run by the
149 Freeciv maintainers will be used.
150 -m, --meta
152 Directs the server to communicate with a metaserver, a place
153 where Freeciv servers can publish their presence. Freeciv
154 clients consult the metaserver to offer users a selection of
155 games to join. By default the standard Freeciv metaserver is
156 used. You may specify an alternate metaserver with the -M op‐
157 tion.
158 -k, --keep
160 Usually freeciv server stops sending updates to the metaserver,
161 when there's problems on the connection once. With this option
162 it keeps on trying to send further updates even after it has
163 failed to send updated status once. This option implies -m op‐
164 tion.
165 -N, --Newusers
167 Allow new users to login and be registered in the players base
168 if authentication is enabled.
169 -p port, --port port
171 Specifies the TCP port number to which clients will connect;
172 players must know this number to be able to connect if they are
173 not to use the default of 5556 decimal. You may need to use this
174 if 5556 is not available for your use on your system, or if you
175 would like to run multiple servers on the same system.
176 -q time, --quitidle time
178 Quits if no players are present for the specified time, in sec‐
179 onds, and restarts a new server.
180 -R filename, --Ranklog filename
182 Defines a log file, filename, to be produced during processing.
183 This log contains information for player ranking.
184 -r filename, --read filename
186 Specifies a file, filename, of server commands which the server
187 will automatically read and process, as if you had typed them in
188 at the server's prompt. The distribution comes with a few exam‐
189 ples, including files that set options to be similar to Civi‐
190 lization I® and Civilization II® . The files are named civ1.serv
191 and civ2.serv, and are typically found at /usr/lo‐
192 cal/share/freeciv/.
193 -S id, --Serverid id
195 Sets the server id. This is used to identify a particular run‐
196 ning game.
197 -s directory, --saves directory
199 Specifies the directory to place save game files created by the
200 server. This is especially useful when you're running more than
201 one server on the same system, as it inhibits your servers from
202 clobbering other's save game files.
203 (This does not influence where the server looks when loading
205 save game files; see FREECIV_SAVE_PATH for that.)
206 --scenarios directory
208 Specifies the directory to place scenarios saved by the server
209 (for instance, those created with the in-game editor).
210 (This does not influence where the server looks when loading
212 scenario files; see FREECIV_SCENARIO_PATH for that.)
213 -v, --version
215 Causes the server to display its version number and exit.
216
218 freeciv-server --file oldgame.sav --port 2244
219 Starts a server on port 2244, loading the save game file
220 oldgame.sav.
221 freeciv-server -R ranklog -l logfile -r script -f oldgame.sav.gz -p
223 2244
224 Starts a server on port 2244, loading the save game file
225 oldgame.sav.gz. Ranking related events are written to ranklog,
226 other logging information is written to logfile. When the server
227 starts, it immediately executes the commands contained in
228 script.
229 freeciv-server -m -a -D fc_auth.conf -q 60 -p 2244 -d normal -l logfile
231 -r script -s ~/saves
232 Starts a server on port 2244 with authentication enabled and
233 communicates its existence to the standard Freeciv metaserver.
234 Fatal, error, and normal messages are written to logfile. When
235 the server starts it immediately executes the commands contained
236 in script. Save game files are stored in the ~/saves directory.
237 When there are no users on the server for 60 seconds, the server
238 will restart.
239
241 You may enter commands into the server at any time, either before or
242 during the running of a game.
243 Type "help" or "help help" for starters.
245
247 The Freeciv server requires the following files in the Freeciv data di‐
248 rectory, which is /usr/local/share/freeciv by default:
249 • civ2civ3/buildings.ruleset
251 • civ2civ3/cities.ruleset
253 • civ2civ3/effects.ruleset
255 • civ2civ3/game.ruleset
257 • civ2civ3/governments.ruleset
259 • civ2civ3/nations.ruleset
261 • civ2civ3/styles.ruleset
263 • civ2civ3/techs.ruleset
265 • civ2civ3/terrain.ruleset
267 • civ2civ3/units.ruleset
269 • civ2civ3/script.lua
271 • default/default.lua
273 • default/nationlist.ruleset
275 These are the default rule sets used for the game. Alternate sets of
277 rules can be used by placing them in a separate directory and using the
278 rulesetdir command to change your server's ruleset directory.
279 Type help rulesetdir for more information.
281
283 The Freeciv server accepts these environment variables:
284 FREECIV_CAPS
286 A string containing a list of "capabilities" provided by the
287 server. The compiled-in default should be correct for most pur‐
288 poses, but if you are familiar with the capability facility in
289 the source you may use it to enforce some constraints between
290 clients and server.
291 FREECIV_COMPRESSION_LEVEL
293 Sets the compression level for network traffic.
294 FREECIV_DATA_ENCODING
296 Sets the character encoding used for data files, savegames, and
297 network strings). This should not normally be changed from the
298 default of UTF-8, since that is the format of the supplied rule‐
299 sets and the standard network protocol.
300 FREECIV_INTERNAL_ENCODING
302 Sets the character encoding used internally by freeciv-server;
303 this encoding should not be visible at any interface. Defaults
304 to UTF-8.
305 FREECIV_LOCAL_ENCODING
307 Sets the local character encoding (used for the command line and
308 terminal output). The default is inferred from other aspects of
309 the environment.
310 FREECIV_MULTICAST_GROUP
312 Sets the multicast group (for the LAN tab).
313 FREECIV_DATA_PATH
315 A colon separated list of directories pointing to the freeciv
316 data directories. By default Freeciv looks in the following di‐
317 rectories, in order, for any data files: the current directory;
318 the "data" subdirectory of the current directory; the subdirec‐
319 tory ".freeciv/3.0" in the user's home directory; and the direc‐
320 tory where the files are placed by running "make install". If
321 not set, FREECIV_SAVE_PATH A colon separated list of directories
322 pointing to the freeciv save directories. By default Freeciv
323 looks in the following directories, in order, for save files:
324 the current directory; and the subdirectory ".freeciv/saves" in
325 the user's home directory.
326 (This does not affect where the server creates save game files;
328 see the --saves option for that.)
329 FREECIV_SCENARIO_PATH
331 A colon separated list of directories pointing to the freeciv
332 scenario directories. By default Freeciv looks in the following
333 directories, in order, for scenario files: the current direc‐
334 tory; the "data/scenarios" subdirectory of the current direc‐
335 tory; the subdirectories ".freeciv/3.0/scenarios" and then
336 ".freeciv/scenarios" in the user's home directory; and the di‐
337 rectory where the files are placed by running "make install".
338 (This does not affect where the server creates scenario files;
340 see the --scenarios option for that.)
341 HOME Specifies the user's home directory.
343 http_proxy
345 Set this variable accordingly when using a proxy.
346 LANG or LANGUAGE
348 Sets the language and locale on some platforms.
349 LC_ALL or LC_CTYPE
351 Similar to LANG (see documentation for your system).
352 USER Specifies the username of the current user.
