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® by Microprose® 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 ⟨http://www.freeciv.org/⟩ 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_number, --debug level_number
              Sets  the  amount of debugging information to be logged in the file named by the -l
              option. Acceptable values for the level_number are:

              0    for fatal messages only.

              1    for fatal and error messages.

              2    for fatal, error and normal messages (default).

              3    for fatal, error, 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:

              · british-isles-85x80-v2.80.sav

              · earth-160x90-v2.sav

              · earth-80x50-v3.sav

              · europe-200x100-v2.sav

              · hagworld-120x60-v1.2.sav

              · 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,  and  normal  messages  are
              printed to standard output.  With a log file, such messages go to the log instead.

       -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.

       -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® and Civilization II® . 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 2 -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, 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:

       · default/buildings.ruleset

       · default/cities.ruleset

       · default/effects.ruleset

       · default/game.ruleset

       · default/governments.ruleset

       · default/nations.ruleset

       · default/techs.ruleset

       · default/terrain.ruleset

       · default/units.ruleset

       · default/default.lua

       · default/script.lua

       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/2.5"  in the user's home directory; and the directory where
              the files are placed by running  "make  install".   If  not  set,  FREECIV_PATH  is
              checked before these defaults are used.

       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.  If not set, FREECIV_PATH is checked before these defaults are used;  in
              this case Freeciv also looks in "saves" potential subdirectories.

              (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/2.5/scenarios"     and     then
              ".freeciv/scenarios" in the user's home directory;  and  the  directory  where  the
              files  are  placed  by running "make install".  If not set, FREECIV_PATH is checked
              before these defaults are used; in this case Freeciv also looks in  "scenario"  and
              "scenarios" potential subdirectories.

              (This  does not affect where the server creates scenario files; see the --scenarios
              option for that.)

       FREECIV_PATH
              A colon separated list of directories to look for various files.  This variable has
              no  effect  if  FREECIV_DATA_PATH,  FREECIV_SAVE_PATH and FREECIV_SCENARIO_PATH are
              defined together; those variables are the recommended way to override  paths,  with
              FREECIV_PATH  provided  for  backward compatibility with older versions of Freeciv.
              The precise search path depends on the type of file being searched for.

       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.
