DESCRIPTION
Freeciv is a free turn-based multiplayer strategy game, in which each
player becomes the leader of a civilization, fighting to obtain the
ultimate goal: To become the greatest civilization.
Players of Civilization II(R) by Microprose(R) should feel at home,
since one aim of Freeciv is to have compatible rules.
Freeciv is maintained by an international team of coders and
enthusiasts, and is easily one of the most fun and addictive network
games out there!
This is the server program used to establish a Freeciv server - see
also freeciv-client(6) .
This manual page only lists the command line arguments. For details of
the directives necessary to configure freeciv-server see the Server
Manual which can be found at the Freeciv website
as well as the documentation which is part
of the Freeciv distribution.
OPTIONS
The following options are accepted on the command line of the server.
They may not be combined; that is, "freeciv-server -fp savegame.sav
5557" will not work, instead you would need to enter "freeciv-server -f
savegame.sav -p 5557". Most options have a short form (single hyphen
and single letter) and a long form (double hyphen and a complete word);
their effects are identical.
-A protocol, --Announce protocol
Uses protocol when announcing game in LAN. Possible values for
protocol are:
IPv4
IPv6
none
-a, --auth
Enables server authentication and allows access to registered
players only. Requires the --Database option to be specified.
-b address, --bind address
Sets the address on which the server will listen for clients.
-B address, --Bind-meta address
Sets the address which request to metaserver are sent from.
Defaults to address given by -b option.
-d level, --debug level
Sets the amount of debugging information to be logged in the
file named by the -l option. Acceptable values for the level
are:
fatal for fatal messages only.
error for fatal and error messages.
warning for fatal, error and warning messages
normal for fatal, error, warning and normal messages
(default).
verbose for fatal, error, warning, normal, and verbose
messages.
-D filename, --Database filename
Specifies a database configuration file for authentication. This
file specifies the details of the database. See README.fcdb in
the Freeciv distribution for details of its format.
-e, --exit-on-end
When a game ends, exit instead of restarting.
-F [ signal_number ], --Fatal [ signal_number ]
Raise a custom signal on failed assertion. If signal_number is
not specified, then the ABRT signal will be used.
-f filename, --file filename
Loads a saved game (filename) into the server before
initialization, instead of starting a new game. This is for
reloading saved games, or for loading scenarios. See ENVIRONMENT
for where the server looks for these files.
The distribution comes with several scenarios, typically stored
in /usr/local/share/freeciv/scenarios, for example:
o british-isles-85x80-v2.80.sav
o earth-160x90-v2.sav
o earth-80x50-v3.sav
o europe-200x100-v2.sav
o hagworld-120x60-v1.2.sav
o iberian-peninsula-136x100-v1.0.sav
-G, --Guests
Allow guests to login as 'guest' when authentication is enabled.
-h, --help
Prints out a description of the command line options and exits.
-i address, --identity address
Reports the address to the metaserver. Then, the metaserver
will use this address to redirect the users.
-L module, --LoadAI module
Loads AI module. This option can appear multiple times to load
different modules.
-l filename, --log filename
Defines a log file, filename, to be produced during processing.
Use the -d option to set how much is logged. By default, fatal,
error, warning, and normal messages are printed to standard
output. With a log file, such messages go to the log instead.
If filename already exists, it is appended to.
-M address, --Metaserver address
Specifies the address of the metaserver to send your server's
information to. By default, the standard metaserver run by the
Freeciv maintainers will be used.
-m, --meta
Directs the server to communicate with a metaserver, a place
where Freeciv servers can publish their presence. Freeciv
clients consult the metaserver to offer users a selection of
games to join. By default the standard Freeciv metaserver is
used. You may specify an alternate metaserver with the -M
option.
-k, --keep
Usually freeciv server stops sending updates to the metaserver,
when there's problems on the connection once. With this option
it keeps on trying to send further updates even after it has
failed to send updated status once. This option implies -m
option.
-N, --Newusers
Allow new users to login and be registered in the players base
if authentication is enabled.
-p port, --port port
Specifies the TCP port number to which clients will connect;
players must know this number to be able to connect if they are
not to use the default of 5556 decimal. You may need to use this
if 5556 is not available for your use on your system, or if you
would like to run multiple servers on the same system.
-q time, --quitidle time
Quits if no players are present for the specified time, in
seconds, and restarts a new server.
-R filename, --Ranklog filename
Defines a log file, filename, to be produced during processing.
This log contains information for player ranking.
-r filename, --read filename
Specifies a file, filename, of server commands which the server
will automatically read and process, as if you had typed them in
at the server's prompt. The distribution comes with a few
examples, including files that set options to be similar to
Civilization I(R) and Civilization II(R) . The files are named
civ1.serv and civ2.serv, and are typically found at
/usr/local/share/freeciv/.
-S id, --Serverid id
Sets the server id. This is used to identify a particular
running game.
-s directory, --saves directory
Specifies the directory to place save game files created by the
server. This is especially useful when you're running more than
one server on the same system, as it inhibits your servers from
clobbering other's save game files.
(This does not influence where the server looks when loading
save game files; see FREECIV_SAVE_PATH for that.)
--scenarios directory
Specifies the directory to place scenarios saved by the server
(for instance, those created with the in-game editor).
(This does not influence where the server looks when loading
scenario files; see FREECIV_SCENARIO_PATH for that.)
-v, --version
Causes the server to display its version number and exit.
EXAMPLES
freeciv-server --file oldgame.sav --port 2244
Starts a server on port 2244, loading the save game file
oldgame.sav.
freeciv-server -R ranklog -l logfile -r script -f oldgame.sav.gz -p
2244 Starts a server on port 2244, loading the save game file
oldgame.sav.gz. Ranking related events are written to ranklog,
other logging information is written to logfile. When the server
starts, it immediately executes the commands contained in
script.
freeciv-server -m -a -D fc_auth.conf -q 60 -p 2244 -d normal -l logfile
-r script -s ~/saves
Starts a server on port 2244 with authentication enabled and
communicates its existence to the standard Freeciv metaserver.
Fatal, error, warning, and normal messages are written to
logfile. When the server starts it immediately executes the
commands contained in script. Save game files are stored in the
~/saves directory. When there are no users on the server for 60
seconds, the server will restart.
COMMANDS
You may enter commands into the server at any time, either before or
during the running of a game.
Type "help" or "help help" for starters.
FILES
The Freeciv server requires the following files in the Freeciv data
directory, which is /usr/local/share/freeciv by default:
o civ2civ3/buildings.ruleset
o civ2civ3/cities.ruleset
o civ2civ3/effects.ruleset
o civ2civ3/game.ruleset
o civ2civ3/governments.ruleset
o civ2civ3/nations.ruleset
o civ2civ3/styles.ruleset
o civ2civ3/techs.ruleset
o civ2civ3/terrain.ruleset
o civ2civ3/units.ruleset
o civ2civ3/script.lua
o default/default.lua
o default/nationlist.ruleset
These are the default rule sets used for the game. Alternate sets of
rules can be used by placing them in a separate directory and using the
rulesetdir command to change your server's ruleset directory.
Type help rulesetdir for more information.
ENVIRONMENT
The Freeciv server accepts these environment variables:
FREECIV_CAPS
A string containing a list of "capabilities" provided by the
server. The compiled-in default should be correct for most
purposes, but if you are familiar with the capability facility
in the source you may use it to enforce some constraints between
clients and server.
FREECIV_COMPRESSION_LEVEL
Sets the compression level for network traffic.
FREECIV_DATA_ENCODING
Sets the character encoding used for data files, savegames, and
network strings). This should not normally be changed from the
default of UTF-8, since that is the format of the supplied
rulesets and the standard network protocol.
FREECIV_INTERNAL_ENCODING
Sets the character encoding used internally by freeciv-server;
this encoding should not be visible at any interface. Defaults
to UTF-8.
FREECIV_LOCAL_ENCODING
Sets the local character encoding (used for the command line and
terminal output). The default is inferred from other aspects of
the environment.
FREECIV_MULTICAST_GROUP
Sets the multicast group (for the LAN tab).
FREECIV_DATA_PATH
A colon separated list of directories pointing to the freeciv
data directories. By default Freeciv looks in the following
directories, in order, for any data files: the current
directory; the "data" subdirectory of the current directory; the
subdirectory ".freeciv/3.1" in the user's home directory; and
the directory where the files are placed by running "make
install". If not set, FREECIV_SAVE_PATH A colon separated list
of directories pointing to the freeciv save directories. By
default Freeciv looks in the following directories, in order,
for save files: the current directory; and the subdirectory
".freeciv/saves" in the user's home directory.
(This does not affect where the server creates save game files;
see the --saves option for that.)
FREECIV_SCENARIO_PATH
A colon separated list of directories pointing to the freeciv
scenario directories. By default Freeciv looks in the following
directories, in order, for scenario files: the current
directory; the "data/scenarios" subdirectory of the current
directory; the subdirectories ".freeciv/3.1/scenarios" and then
".freeciv/scenarios" in the user's home directory; and the
directory where the files are placed by running "make install".
(This does not affect where the server creates scenario files;
see the --scenarios option for that.)
HOME Specifies the user's home directory.
http_proxy
Set this variable accordingly when using a proxy.
LANG or LANGUAGE
Sets the language and locale on some platforms.
LC_ALL or LC_CTYPE
Similar to LANG (see documentation for your system).
USER Specifies the username of the current user.
