kickTimeout[] = { { kickID, timeout }, ... };
kickID (type to determine from where the kick originated e.g. admin or votekick etc.)

• 0 - manual kick (vote kick, admin kick, bruteforce detection etc.)
• 1 - connectivity kick (ping, timeout, packetloss, desync)
• 2 - BattlEye kick
• 3 - harmless kick (wrong addons, steam timeout or checks, signatures, content etc.)
  

timeout = in seconds how long until kicked player can return

• >0 seconds
• -1 until missionEnd
• -2 until serverRestart

Independent of set lobbyIdleTimeout in the config file, it will be at least
MAX(votingTimeout, lobbyTimeout, briefingTimeout, debriefingTimeout) + 5 secondsby default, this makes it 300 seconds of time for people in lobby and 95 in roleTimeout or briefing screen

1.90missionsToServerRestart = 8;0Number of times missionEnd happens before server initiate process restart (uses actual session startup command-line parameters, not possible to combine with `missionsToShutdown` )N/AmissionsToShutdown = 8;0Number of times missionEnd happens before server initiate process shutdown (has same behavior as setting named `missionsToHardRestart`)N/AautoSelectMission = true;falseWhen enabled, the server auto-starts next mission in mission cycle and waits for players in the role selection. This allows full mission information in server browser and then results in proper filtering of the servers. This is lesser-variant (trimmed) of server startup command-line parameter -autoInit. Might collide with campaign linked missions / need mission cycle etc.N/ArandomMissionOrder = true;falseWhen enabled, the server random start / next selection with one of missions from mission rotation list. ( setting goes outside(before) Mission class {}; )N/AdisableChannels[] = { { 0, false, true } };{}

disableChannels[] = { { channelID, text, voice }, ... }>;

• ChannelID: Number - use single digit of (0 to 6) to define channelID. Default: No restriction to any channels, with text/von chat set to false.
  
• text: Boolean - use true to disable usage of text-chat for defined channelID. Default: false
  
• voice: Boolean - use true to disable usage of voice-chat (VON) for defined channelID. Default: false

-Other OptionsverifySignatures = 2;2Enables or disables the signature verification for addons.

• Verification disabled = 0.
• 1 Will default back to 2

-drawingInMap = false;trueEnables or disables the ability to place markers and draw lines in map.1.64disableVoN = 1;0Enables or disables the Voice over Net.N/AvonCodecQuality = 10;3Defines VoN codec quality. Value range is from 1 to 20.

• Since 1.62 supports range 1-20
• Since 1.64 will support range 1-30
• 8kHz is 0-10, 16kHz is 11-20, for 21-30 it is 32kHz for SPEEX codec and 48kHz for OPUS codec.

-vonCodec = 1;1Defines VoN codec type. Value range is from 0 to 1.

• Since Arma 3 update 1.58 supports value 1
• Value 0 uses older SPEEX codec, while 1 switches to new IETF standard OPUS codec.

-skipLobby = false;falseIf true, joining player will skip role selection. This is only used if no Mission, Campaign or Config setting skipLobby is defined (See Description.ext#skipLobby).N/AallowProfileGlasses = false;trueIf false, glasses set in player profile will be ignored. This is only used if no Mission, Campaign or Config setting allowProfileGlasses is defined (See Description.ext - allowProfileGlasses)2.06zeusCompositionScriptLevel = 0;1

• 0: all scripts are forbidden
• 1: only attributes are allowed (including custom attributes added by mods)
• 2: all scripts are allowed including init scripts

This is only used if no Mission, Campaign or Config setting zeusCompositionScriptLevel is defined (See Description.ext - zeusCompositionScriptLevel).

2.06logFile = "server_console.log";unknownEnables output of dedicated server console into textfile. Default location of log is same as crash dumps and other logs. (Local settings) Note that this does not change the location of the "net.log" file, which is enabled with the -netlog command line option.N/AdoubleIdDetected = "command";""See Server Side ScriptingonUserConnected = "command";""N/AonUserDisconnected = "command";""N/AonHackedData = "command";""N/AonDifferentData = "command";""N/AonUnsignedData = "command";""N/AonUserKicked = "command";""N/AregularCheck = "command";""N/ABattlEye = 1;1Enables or disables the BattlEye anti-cheat engine.

Possible values are "none", "short", "full".N/AforceRotorLibSimulation = 0;0Enforces the Advanced Flight Model on the server. 0 (up to the player). 1 - forced AFM, 2 - forced SFM.1.34persistent = 1;0Mission keeps running when all clients disconnect. Enabling the persistence option will make missions that have either base or instant respawn keep on running after all players have disconnected. The other respawn types will not make a mission persistent. The kind of respawn a certain mission uses is set in its Description.ext.N/ArequiredBuild = xxxxx;0Minimum required client version. Clients with version lower than requiredBuild will not be able to connect. If requiredBuild is set to a large number, like requiredBuild = 999999999; for example, it will automatically be lowered to the current server version.N/AstatisticsEnabled = 1;1Allows to opt-out of Arma 3 analytics for the server by using 01.56forcedDifficulty = "regular";""Enforces the selected difficulty on the server. forcedDifficulty = "<difficultyClass>";

• If Recruit, Regular or Veteran is passed as the parameter, the particular difficulty options will be taken from data config, from the class CfgDifficultyPresets.
• If Custom will be passed as the parameter, the particular flags will be taken from CustomDifficulty class from server's profile (only Custom is saved to the profile).
• If mission cycle is defined in the server.cfg, the difficulty set in the mission cycle overrides the difficulty set by forcedDifficulty parameter.

1.56missionWhitelist[] = { "intro.altis" };{}Limit the available missions for the admin for the mission change. See Arma 3: MP Mission Names for a full list.1.56steamProtocolMaxDataSize = 1024;1024Limit for maximum Steam Query packet length. Increasing this value is dangerous as it can cause Arma 3 server to send UDP packets of a size larger than the MTU. This will cause UDP packets to be fragmented which is not supported by some older routers. But increasing this will fix the modlist length limit in Arma 3: Launcher.2.00N/A

2.02

• LogObjectNotFound - false to skip logging "Server: Object not found" messages
• SkipDescriptionParsing - true to skip parsing of description.ext/mission.sqm. Will show pbo filename instead of configured missionName. OverviewText and such won't work, but loading the mission list is a lot faster when there are many missions

2.04

• ignoreMissionLoadErrors - when set to true, the mission will load no matter the amount of loading errors. If set to false, the server will abort mission's loading and return to mission selection

2.08

• queueSizeLogG - if #monitor is running and a player's Guaranteed Message Queue size (Listed as G: in #monitor) goes above the threshold, all that player's message types and sizes are dumped to a logfile in the RPT directory (see Crash Files); the dumping itself is logged server-side.

2.022.042.08armaUnitsTimeout = 30;30Defines how long the player will be stuck connecting and wait for armaUnits data. Player will be notified if timeout elapsed and no units data was received2.06overrideHazeQuality = 1;-10/1/2 - VeryLow/Low/Standard - Forces haze quality in MP on all clients. Standard (2) - mod config driven. Default (-1) - do not force. Mission config's overrideHazeQuality has priority over the server option.2.16

cycle is time in seconds.Every cycle, if player sends more than "limit" number of messages, they get flagged.

If the last 4 out of 8 cycles were flagged or if within one cycle the hard limit is exceeded,the player is kicked (if enableKick is set to true) or logged to RPT that they exceeded the limit.
