DESCRIPTION

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.

OPTIONS

-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 ratio.
-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 server.
-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 obtained.
-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.
-filterCallsigns
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 only.
-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 players.
-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 default.
-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.
-noMasterBanlist
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
banTime
default number of minutes player should be banned (unspecified, the default is 300)
vetoTime
max seconds authorized user has to abort poll (default is 20)
votePercentage
percentage of players required to affirm a poll (unspecified, the default is 50.1%)
voteRepeatTime
minimum seconds required before a player may request another vote (default is 300)
votesRequired
minimum number of additional votes required to make a vote valid (default is 2)
voteTime
maximum amount of time player has to vote, in seconds (default is 60)
-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 megabytes).
-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 clients.
-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.
-trackplayhistory
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

Notes

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 limit).

The following game styles are recommended starting points.

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

Networking

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.

Worlds

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 sourceforge.net through cvs, or can be hand edited. See the bzw(5) manual page for more details.

GENERAL SERVER COMMANDS

/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
/flaghistory
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)
/idlestats
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
/lagstats
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!
/uptime
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.

USER MANAGEMENT

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. EVERYONE has ACTIONMESSAGE, ADMINMESSAGESEND, DATE, FLAGHISTORY, IDLESTATS, LAGSTATS, PRIVATEMESSAGE and SPAWN by default. VERIFIED has POLL, POLLKICK, POLLBAN, POLLSET, 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 http://my.BZFlag.org/bb/ 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 group.

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 format:

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:

COPS: +KICK +SHORTBAN +BANLIST

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

USERADMIN: *COPS +BAN +UNBAN

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?

EVERYONE: !POLL

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.:

LOCAL.OPERATOR: BANLIST

The available permissions are as follows:
