       Bzfs  is  the  server  for  BZFlag,  and it must be running to play.  It can be run on any
       system on the network (including a player's system or one without graphics).   Terminating
       the server terminates the game in progress.


       -a linear angular
                      Sets  the maximum linear and angular accelerations.  The units are somewhat
                      arbitrary so you'll have to experiment to find  suitable  values.  Positive
                      values  will  set limits to the acceleration and lower they are, greater is
                      the inertia.  Zero or negative values disable acceleration limits.

       -adminlagannounce milliseconds
                      Announce players that lag more than milliseconds to admins.

       -admsg message Define a message which will be broadcast to all players every  15  minutes.
                      This option can be used multiple times to define a multiline message.

       -advertise groupname,groupname,...
                      Allows  control  of  who  can  see  this  server  on the server list.  Use:
                      -advertise NONE to make a private server (no one will see the  server,  but
                      global logins can be used). The default, if -advertise is not specified, is
                      to allow everyone to see the server.  Otherwise, your server will  only  be
                      listed to members of the groups which you specify, eg: -advertise JOE,BOB.

       -autoTeam      Automatically  assign  players to teams when they connect so that there are
                      an equal number of players on all available teams.  Players are  placed  on
                      teams  that  have  the fewest players; otherwise they will be placed on the
                      weakest team.  Weakest team is the  team  with  the  lowest  combined  kill

       -b             When -c is supplied, this option randomly rotates the buildings.

       -badwords badwordfile
                      Specify  a  file  that  contains  bad  words  that will be used when either
                      -filterCallsigns or -filterChat is enabled.

       -ban ip[,ip]...
                      Prohibits connections from the listed IP addresses. Trailing 255 bytes  are
                      treated as mask bytes.

       -banfile filename
                      Specifies  the  name  of  a file where bzfs will store the banlist. It will
                      load the banlist from this file when it starts (if the  file  exists),  and
                      write  the  banlist  back to the file when someone gets banned or unbanned.
                      If this option isn't given the banlist will not be saved.

       -c             Enables the capture-the-flag style game. By default this allocates one team
                      flag  per  team.   This  can  be  modified  see  +f  team.  By default, the
                      free-for-all style is used.

       -cache worldCacheURL
                      Specifies the URL for the world cache file. This  is  a  binary  file  that
                      clients  will  attempt  to  download before getting the world from the bzfs

       -cacheout filename
                      Save the currently specified world into a binary cache file and exit.

       -conf configfilename
                      Specifies the name of a configuration file to be used to  set  all  of  the
                      bzfs options, rather than setting them on the command line.

       -cr            Enables   the  capture-the-flag  style  game  with  random  map.   You  can
                      optionally specify a building density by providing a number (default is 5).
                      One team flag per team is provided, but more can be added thru +f team.  By
                      default, the free-for-all style is used.

       -d             Increase debugging level. If more -d  is  given,  more  debugging  info  is

       -density num   Specify density for buildings, i.e. the higher the integer number, the more
                      buildings you will get. This applies to automatically generated maps only.

       -disableBots   Disallow clients from using the ROGER autopilot or from using robots.

       +f {good|bad|teamflag-id}[{count}]
                      Forces the existence of the given flag.  If specified  multiple  times  for
                      the  same  flag-id, then that many flags will appear.  The good argument is
                      equivalent to specifying +f once for each kind of good flag. Same goes  for
                      the  bad  argument.   The  team  argument  adds  a  team flag to each team,
                      assuming that the game style is capture  the  flag.  The  optional  {count}
                      parameter allows the specification of multiple flags of the same type. Note
                      that the curly braces are required.

       -f {good|bad|flag-id}
                      Disallows random flags of the given type.  Required flags given by  the  +f
                      option are still provided.  The bad argument is equivalent to specifying -f
                      once for each kind of bad flag.  Same goes for good, but  you  probably  do
                      not want to do that.

       An example of running a server with 40 to 50 flags except genocide would
                      be  "+s40  -s50  -f G".  Similarly, "+f good{40} +f bad{10} -f G{40}" would
                      give you exactly 40 good flags except genocide and 10 of each bad flag.

       -fb            Allow flags on box buildings.

                      Turn on the filtering of callsigns  and  email  addresses.   Callsigns  and
                      addresses are compared against bad words provided via -badwords.

       -filterChat    Turn on the filtering of chat messages.  Messages that contain words listed
                      via a -badwords file are replaced with !@#$%^&* characters.

       -filterSimple  By default, all filtering is aggressive, matching much more  than  what  is
                      strictly listed in a -badwords file for convenience.  Providing this option
                      will make the -filterCallsigns  and  -filterChat  comparisons  exact  match

       -g             Quit after serving one game.

       -groupdb file  Load groups from file

       -h             Buildings are given random heights.

       -handicap      Players  are  given a handicap advantage based on their ability in relation
                      to the other players. Handicapped players will have faster tanks and shots.
                      The  handicap  is  determined  by  the  player's score in relation to other

       -help          Shows a help page and lists all the valid flag id's.

       -helpmsg file name
                      Create a help message accessible by /help name, which prints  the  contents
                      of file. Restricted to 10 lines per help message.

       -i interface   Server will listen for and respond to ``pings'' (sent via broadcast) on the
                      given interface.  Clients use this to find active servers on  the  network.
                      This is the TCP/UDP/IP address the server will listen on.

       -j             Allows jumping.

       -jitterdrop warn-count
                      Kicks players after warn-count jitter warnings.

       -jitterwarn milliseconds
                      Send warnings to players that jitter more than milliseconds.

       -lagannounce milliseconds
                      Announce players that lag more than milliseconds in public.

       -lagdrop warn-count
                      Kicks players after warn-count lag warnings.

       -lagwarn milliseconds
                      Send warnings to players that lag more than milliseconds.

       -masterBanURL URL
                      Specify  alternate  URLs  for  the master ban file to be pulled from.  This
                      argument may be provided multiple times.

       -maxidle seconds
                      Kick players that did not play longer than seconds. Pausing players are not
                      kicked. If a player uttered a word recently, he will be kicked after thrice
                      the given time.

       -mp {count|[rogue],[red],[green],[blue],[purple],[observer]}
                      Sets the maximum number of players, total or per team.  A single value sets
                      the  total  number of players allowed.  Five comma separated values set the
                      maximum for each team.  If a count is left blank then no limit is  set  for
                      that team, except for the limit on the total number of players.  Both forms
                      may be provided.

       -mps max-score Sets a maximum score for individual players.  The  first  player  to  reach
                      this score is declared the winner and the game is over.

       -ms shots      Allows  up  to  shots  simultaneous  shots  for  each player.  This is 1 by

       -mts max-score Sets a maximum score for teams.  The first team  to  reach  this  score  is
                      declared the winner and the game is over.

                      Server will not attempt to load the master ban list from the internet.

       -p port        Listen for game connections on port instead of the default port.  Use -help
                      to print the default port, or use -d debug printing.

       -packetlossdrop warn-count
                      Kicks players after warn-count packetloss warnings.

       -packetlosswarn percent
                      Send warnings to players that have more more than percent loss.

       -passdb file   Load passwords from file

       -passwd password
                      Specify a server administrator password for use  in  remote  administration
                      such as /kick, /ban, /mute, etc  messages.

       -pidfile filename
                      Specify a file where the server will write its process ID so it may be used
                      for remote administration.

       -poll variable=value
                      Configure several aspects of the in-game polling system

                             default number of minutes player should be banned (unspecified,  the
                             default is 300)

                             max seconds authorized user has to abort poll (default is 20)

                             percentage  of  players  required to affirm a poll (unspecified, the
                             default is 50.1%)

                             minimum seconds required before a player may  request  another  vote
                             (default is 300)

                             minimum  number  of  additional  votes required to make a vote valid
                             (default is 2)

                             maximum amount of time player has to vote, in  seconds  (default  is

       -printscore    Write score to stdout whenever it changes

       -public description
                      Advertise  this  server  on  the  internet  with the given description.  By
                      default, a server will respond to broadcast queries,  allowing  clients  to
                      find servers running on the standard port on the local subnet.  The -public
                      option causes the server to register  itself  with  a  list  server,  which
                      clients can query to get a list of bzfs servers.

       -publicaddr address[:port]
                      Advertise  this server with the given address and port.  Only has an effect
                      when used with -public.  Normally a server advertises itself at  the  local
                      address  and  port.   Some  servers are not accessible from the internet at
                      this address (for example servers behind a firewall using  Network  Address
                      Translation).   Use  this  option  to  specify the address and/or port that
                      internet users should use to access this server.

       -publiclist url
                      Advertise this server on the list servers  listed  at  url.   Only  has  an
                      effect  when  used  with  -public.  A built-in url is used by default.  The
                      BZFlag clients use the same built-in url so, by default, clients  will  see
                      public servers automatically.  This argument may be provided multiple times
                      to publicize a server to multiple list servers.

       -q             If specified, the server will not listen  for  nor  respond  to  ``pings''.
                      BZFlag  sends out these pings to give the user a list of available servers.
                      This effectively makes the server private, especially if the -p  option  is
                      also used.

       +r             Makes most shots ricochet.  Super bullets, shock waves, and guided missiles
                      do not.

       -rabbit [score|killer|random]
                      Enables the rabbit-hunt style game.  By default, the free-for-all style  is
                      used.   You  must  specify the algorithm used to pick a new rabbit when the
                      old one dies.  The score algorithm uses a modified wins/(wins+losses) score
                      and  picks  the  top  scoring  player  to  be  the  new rabbit.  The killer
                      algorithm specifies a reverse tag game  where  whomever  kills  the  rabbit
                      becomes  the  new rabbit.  The random algorithm randomly picks a new rabbit
                      without regard to score.  (The score algorithm is the original behavior.)

       -recbuf size   Start with the  recording  buffer  active,  with  the  specified  size  (in

       -recbufonly    Disable recording straight to files

       -recdir directory
                      Specify the directory for record and replay files.

       -replay        Start the server in replay mode.

       -reportfile filename
                      Write  messages  to  the  server admin written using the /report command to
                      this file. If neither  -reportfile  or  -reportpipe  is  used  the  /report
                      command will be disabled.

       -reportpipe command
                      Pipe messages to the server admin written using the /report command to this
                      program or shell command. See -reportfile.

       -requireudp    Require clients to use parallel UDP. If players fire before opening  a  UDP
                      channel, kick them off the server.

       +s num-flags   The server will have an extra num-flags random super flags available at all
                      times.  The -f option can be used to restrict which types of flags will  be
                      added.   Required  flags  given  by  the  +f option are not included in the
                      num-flags total.

       -s num-flags   The server will have up to num-flags random super flags  available  at  any
                      time.   The  -f option can be used to restrict which types of flags will be
                      added.  Required flags given by the +f  option  are  not  included  in  the
                      num-flags total.

       -sa            Antidote flags are provided for players with bad flags.

       -sb            Allow spawns on box buildings.

       -set name value
                      Set BZDB variable name to value

       -sl id num     Restrict flag id to num shots.

       -spamtime time Minimum time between player chat messages that are alike.

       -spamwarn warnLimit
                      Number of warnings a player/spammer gets, who  violates -spamtime.

       -speedtol factor
                      Override  the default speed auto kick factor. The factor should not be less
                      then 1.0. The factor is a multiplier.

       -srvmsg message
                      Define a server welcome message. This option can be used multiple times  to
                      define a multiline message.

       -st time       Bad flags are automatically dropped after time seconds.

       -sw count      Bad  flags  are  automatically  dropped after count wins.  Capturing a team
                      flag does not count as a win.

       -synctime      Forces all clients to use the same  time  of  day.   The  current  time  is
                      determined  by  the  server's clock.  This disables the + and - keys on the

       -t             Adds teleporters to the game.

       -tftimeout time-limit
                      If the last player in a team leaves while someone else is carrying the team
                      flag,  the  team  flag  will  not  reset until it is captured, or until the
                      player drops it and it is left alone for some time. This  option  specifies
                      the  number  of  seconds  that  the  flag should be left alone before it is
                      reset. The default value is 30.

       -time time-limit
                      Sets a time limit on the game to time-limit.   The  game  will  be  stopped
                      time-limit seconds after the first player connects.

       -timemanual    When  using  -time,  the  countdown will start when the first player joins.
                      With -timemanual, the countdown  has  to  be  started  manually  using  the
                      /countdown command. This is useful for matches.

       -tk            Changes  the default behavior where a player dies when he kills a teammate.
                      When using this option, he will just get a -1 score penalty  for  the  kill
                      but not be killed in game.

       -tkkr percent  Kicks  players  whose  team  killing  to  normal kill ratio is greater than
                      percent [1-100]. A start up grace period is given to players.

                      Has the server track players with good runs of  kills  and  anounces  them.
                      Also anounces those players that stop the runs of good players.

       -ts [micros]   Include  timestamp  information  in  DEBUG output - useful for logging.  If
                      micros is specified, microseconds will be added to the timestamp.

       -userdb file   Load group associations from file

       -vars file     Loads values for game configurable variables from file. Entries are one per
                      line  in  the  form:  set  variable value. For a list of variables that are
                      configurable, in the BZFlag client, send a message with /set as the text.

       -version       Prints the version number of the executable.

       -world world-file
                      Reads a specific BZFlag .bzw world layout file for the game map.

       -worldsize world-size
                      Changes the size for random maps

       The server uses nearly zero CPU time when nobody is playing, and even during  a  game  the
       server  uses  very little CPU, so it's not a burden on the system to leave one running and
       it won't interfere with a player using the same system (except on Windows 95, which really
       sucks  at  multitasking).  The server will continue to run until terminated.  If a game is
       in progress when the server goes down, all players will be kicked off and the game will be
       aborted  without  warning.   The  server  resets  itself  when all players have quit.  All
       players must quit to reset the server when a game is over (because  of  a  score  or  time

       The following game styles are recommended starting points.

              -c [-b]        Basic  capture-the-flag  game.   It teaches teamwork and dogfighting

              -s -t          Free-for-all with superflags and teleporters.  Teaches  players  how
                             to  use superflags and teleporters for maximum effect.  You may want
                             to allow players to drop bad flags with any of -sa, -st, and -sw.

       Notice that the maximum number of shots for these styles is one.  Having low  shot  counts
       can  greatly increase general playability and learning speed.  However, this is not always
       true of every game style or game world, and a skilled player will learn  to  deal  with  a
       variety of shot counts.  Single shot games have additional disadvantage in WAN games where
       lag/jitter can cause unfair advantage.  Single shot, non-Jump games  will  teach  valuable
       lessons in dodging, however, and are excellent starting points for the beginner.

       Communication  between the server and clients (i.e. between bzfs and bzflag) during a game
       is via TCP and UDP.  Use the -help option to get the server's default port.  If there's  a
       firewall  between  the  server  and  client, the firewall must accept connections from the
       client to this port and forward them to the server.

       Clients can search for servers by sending broadcast UDP packets.  But they must be on  the
       same  local area network for this to work.  Clients can also find servers advertised using
       -public by querying list servers.

       Game information is relayed through the server. Some communication between  clients,  such
       as  position  and  orientation information, is normally sent via UDP packets.  Other data,
       like flag grab and kill messages, are sent to the server via TCP. The  server  then  turns
       around  and  broadcasts  these  packets   to  all  players.  Since being in a game implies
       connection to the server, all players are guaranteed to get all  messages  sent  via  TCP.
       But  the UDP packets may be discarded.  If other players can see your tank in the game but
       it never appears to move and  shots  go  through  it,  chances  are  high  that  your  UDP
       connection is not working.

       BZFlag  worlds come in two varieties, randomly generated ones, and human designed ones. By
       default, bzfs uses randomly generated world unless you specify the -world command line  or
       configuration  file  option. The world file specified by the -world option is a text based
       file that contains a list of world objects. This file can be created using programs  found
       on  through  cvs,  or can be hand edited.  See the bzw(5) manual page for
       more details.


       /clientquery [callsign]
              Retrieve client version info from all users, or just CALLSIGN if given. Example:
              /clientquery MrApathyCream
              MrApathyCream: Version: BZFlag 1.11.6-20040729-gnu-linux-SDL

       /date, /time
              Responds with the current server local time. /date and /time are exactly the same. Example:
              Tuesday September 08 06:45:54 2004

              Lists what flags players have grabbed in the past. Example:
              MrApathyCream: (<-) (->) (O) (CB) (M) (B) (JM) (WA)
              Gerbol: (L) (GM) (L) (GM) (CL) (ST) (GM) (L)
              captain_macgyver: (SB) (SW)

              Displays the idle time in seconds for each player. A player is idle when
              he is dead and has not respawned yet. Example:
              MrApathyCream: 0s
              Gerbol: 80s
              captain_macgyver: 13s

              Lists network delays, jitter and number of lost resp. out of order packets by player. Example:
              MrApathyCream 335 +- 10ms
              Gerbol 210 +- 3ms
              captain_macgyver 155 +- 0ms  12% lost/ooo

       /me action

              This command displays an "action" that is conveyed to another player.  It allows
              for a little more expressivity in the game.  For example: "/me is hunting wabbits"
              turns into a message like "TimRiker is hunting wabbits" that gets displayed
              differently to other players.

       /msg "callsign" message

              This command allows a player to send a message to another player.  Similar to using
              the "," and "." message keys in the game and then selecting your recipient, this
              will send some message to particular player.  The quotes are optional.

       /part [message]
              Leave the server with a goodbye message (similar to IRC's /part)
              /part Gotta go! bye everyone!

       /password password
              Attempt to gain administrator status Example:
              /password supersecretpassword
              You are now an administrator!

       /poll {{ban|kick} callsign|vote {yes|no}|veto}
              Interact and make requests of the bzflag voting system via the /poll command.
              The ban and kick subcommands request a vote to respectively ban or kick some
              player.  The playername is expected as the next argument.  The vote and veto
              commands behave identical to the /vote and /veto command counterparts,
              expecting the same arguments in following.  By default, you must be registered
              to request or vote on a poll, and an admin to veto.

       /quit [message]
              Quit the game with a goodbye message (similar to IRC's /quit)
              /quit Gotta go! bye everyone!

       /report message
              Write a message to the server administrator. Example:
              /report I like this map!

              Prints server's current running time in days, hours, mins and secs.

       /vote {yes|no}
              If there is a poll active, this command will place a vote in favor or in
              opposition to the poll.  Multiple languages are supported as a vote argument
              in addition to "yes" and "no".  By default, you must be registered to vote on
              a poll.

              Repositions flags. If unused is specified, flags carried by tanks are not affected.

       /flag show
              Shows all flags with information. Example:
              0: p:-1 r:1 g:1 1:V s:1 p:159.1x43.2x0.0
              1: p:2 r:1 g:1 1:SW s:1 p:209.1x143.2x10.0

       /flag up
              Removes all flags from the game

              Ends the current game

       /hostban hostpattern duration reason
              Ban players using the specified hostnames for a certain length of time from using this server.
              /hostban * 2 cheating
              bans all players from for 2 minutes

              List all of the host patterns currently banned from this server.

       /jitterwarn [time]
              Change the maximum allowed jitter time. Example:
              /jitterwarn 50

       /jitterdrop [count]
              Change the number of jitter warnings given before a player is kicked. Example:
              /jitterdrop 3

       /kick {"Player Name"|playerName|#slot} reason
              Kick a player off the server. Example:
              /kick Gerbol
              You were kicked off the server by MrApathyCream

              /kick #1 Team killing
              Kick the player using slot 1 because Team Killing

              Note: Slots numbers are only displayed in admins clients.
              A reason is required

       /kill {"Player Name"|playerName|#slot} [reason]
              Kill a player just like when shooting. Example:

       /mute {#slot|callsign}
              Allows a server admin to remove the ability for a player to communicate with
              other players. Once muted the player may only talk to admins on the server.
              This command removes the TALK permission that is enabled by default for all
              players. (disabling TALK by default would let you run a "silent" server)

       /packetlosswarn [time]
              Change the maximum allowed packetloss. Example:
              /packetloss 1

       /record list
              List all files in the recordings directory

       /record rate seconds
              Set the time between game state updates stored in the recording. This will affect
              the granularity of the 'skips' you can do while replaying a file. It will also
              make the recording files bigger if it is set to a faster update rate.

       /record save filename [seconds]
              Save the recording buffer into a file. If seconds is specified, then only save
              that many previous seconds into the file.

       /record size megabytes
              Set the size of the recording memory buffer

       /record start
              Start recording into the memory buffer

       /record stats
              Display the statistics for the current recording (file or buffered)

       /record stop
              Stop recording into the memory buffer

       /replay load {filename|#index}
              Load the specified recording file by name, or by index
              (same indices as produced by the 'replay list' command)

       /replay loop
              Start looping the recording. This will oftentimes require that all players connected
              to the server rejoin  (to reload the map, etc...)

       /replay play
              Start playing the recording. This will oftentimes require that all players connected
              to the server rejoin  (to reload the map, etc...)

       /replay skip [{+|-} seconds]
              If seconds is specified, then skip that amount of time in the recording.
              Otherwise, skip forwards until there is activity.

       /replay stats
              Show the current replay status (filename, position, etc...)

       /say message
              Generate a public message sent by the server. Example:
              /say This is a servermessage

       /sendhelp {"Player name"|playerName|#slot} help page
              Send the specified help page to a user
              /sendhelp register "Foo"
              Send the the help page 'register' to the player Foo

              Stop serving BZFlag on this server

              Kick all players off the server

       /unmute {#slot|callsign}
              Allows a server admin to restore the TALK permission to a previously muted

       /veto  If there is a poll active, this will cancel the poll.  By default, you must be
              an admin to veto a poll.

              View the server's report file.


       Generally,  you  start  with  empty  files for the user and password databases.  These are
       maintained by the server, and modifiable through server commands.  Users in turn belong to
       groups.   Groups  are  generally  customized  to  perhaps  allow administrative control to
       trusted users.

       There are both local and global groups, i.e. groups that are available across  the  entire
       BZFlag  network.   In setting up a server, you may want to specify global groups that will
       allow already well known and trusted users to police your server and help maintain control
       against cheaters and abuse.

       The  server  will  automatically create three groups: EVERYONE, VERIFIED, and LOCAL.ADMIN.
       POLLFLAGRESET, and VOTE. The  LOCAL.ADMIN  group  has  almost  every  permission  possible
       (similar to granting admin powers via /password).

       Once  the  server  is running, users can register their callsigns and admins can set their
       group memberships. Users can use any command that their  permissions  allow.  Every  user,
       registered or not, is part of the EVERYONE group. When a user identifies, they become part
       of the VERIFIED group.

       In addition, there are global groups available  that  persist  network-wide.   Users  that
       register  their  callsigns  on  the  BZFlag  website  at have the
       ability to globally authenticate by providing a password from  within  the  client.   When
       they  authenticate,  bzfs  will  ask  the  list server if they belong to any of the groups
       listed in your group database file that are not prefixed with "LOCAL.".   If  they  are  a
       member  of a group in question, then they are granted the permissions you specify for that

       A group database file is set up to contain the specific local and global groups  you  care
       to  have  on  your  server in addition to default groups and exactly which permissions are
       granted by each.  These files are laid out with one line per group,  using  the  following

       GROUP_NAME: [*Group] [+|-|!]perm1 [+|-|!]perm2 ... permN

       *Group: inhert permissions from existing group "Group"

       +perm: add perm to this group

       -perm: remove perm from this group

       !perm:  forbid  perm  for  this  group.  makes perm inaccessable whether it's granted from
       another group or not

       If no operator is given with a permission it is handled like +perm. A  group  line  for  a
       previously  existing  group adds to already granted permissions. That way you can spread a
       group's definition over several lines:

       GROUP_NAME: +perm1 +perm2
       GROUP_NAME: +perm3 +perm4 -perm5

       Group names cannot have spaces, quotes, or other special characters in them.   This  would
       be a sample line defining a "cop" group:


       Now a group USERADMIN with all permissions granted to COPS plus some additional could look
       like this:


       Probably you want to define  customized  permissions  for  the  default  group  "VERIFIED"
       instead of those automatically asigned by the server:

       VERIFIED: -ALL +perm1 +perm2 ...

       Or you want to disable the /poll command entirely?


       To  distinguish  between  a  group  that is local and one that is global, use the "LOCAL."
       prefix as part of the group name, e.g.:


       The available permissions are as follows:

       ACTIONMESSAGE       /me
       ADMINMESSAGERECEIVE player receives messages sent to admin channel
       ADMINMESSAGESEND    player may send messages on the admin channel
       ALL                 all permissions available
