Multiplayer Server Commands

For Arma Reforger see Arma Reforger:Server Management.

⚠

It is recommended to use BattlEye's RCon tool to administrate the server.

RCON cannot be affected by in-game script exploits.

It uses custom port which one may easily secure by firewall rules!

How To

You can access the command line by pressing the chat key (default /).

In the chat input window you can type any of the following commands in and confirm them with the enter key.

You have to add the # character before the command.

The commands can be used in SQF scripts by using serverCommand.

ⓘ

Troubleshooting:

Some commands are confirmed via a message in the console.
If you enter a command that is properly formatted, and you see no confirmation of the command, then an error may have occurred.

Check your server log for potentially more information why it failed (e.g. one or more of your mission files is corrupt or has an error which prevents the Missions Lobby from loading, or may prevent other commands like #restart or #reassign from executing).

Commands

The following commands are available to you once you have connected to a server:

Admin Commands

Server/Session Administration

Command	Example	Description
#login #login password	#login #login adminPW	Log in as the admin. Without password only possible if you are listed as an admin[] in Arma 3: Server Config File#Server_Options
#logout		Admin log out.
#mission filename #mission filename difficulty	#mission myDM.intro #mission myDM.intro Veteran	Select mission with known name and set the difficulty. Difficulty parameter is optional and if not set, current difficulty is kept.
#missions		Allows selection of mission on shown list of available missions (all or those inside missionWhiteList[] = {}; within server.cfg). Note: this will trigger `missionEnd` (so if server.cfg is set with e.g. MissionsToServerRestart or MissionsToShutdown threshold, the server may immediately restart/shutdown)
#restart		Restart mission.
#reassign		Start over and reassign roles.
#lock	Locks the server, prevents new clients from joining.
#unlock	Unlocks the server, allows new clients to join.
#shutdown		Shuts down the server immediately
#restartserver		1.66 Shuts down and restarts the server immediately
#shutdownaftermission		1.72 Shuts down the server after mission ends
#restartserveraftermission		1.72 Shuts down and restarts the server after mission ends
#init		Reload server config file loaded by -config option.

Player Punishment

#exec server side command allows executing administration scripting command.

⚠

Only works on dedicated servers.

Command	Example	Description
#exec ban name #exec ban ID #exec ban Player# #exec ban "user reason"	#exec ban nickName #exec ban 47114712 #exec ban 3 #exec ban "3 Griefing" 2.18 #exec ban """Some Username""" ""Some Ban Reason Text"""	Allows you to ban a player. Their ID will be added to the ban.txt file.
#kick name #kick ID #kick Player# #kick user reason	#kick nickName #kick 47114712 #kick 3 2.18 #kick "Some Username" "Some Kick Reason Text"	Allows you to kick a player.

Network/Connection Quality

Command	Example	Description
#maxdesync (amount in %)	#maxdesync 95	Set the maximum accepted desynchronisation Desync is the value you can also see on the map screen when clicking on a player. Or get from networkInfo by getUserInfo. Unclear if percent value or number. The max value seems to be 100000. Note the relation to "yellow chain" and "red chain". 2000 triggers yellow chain. 20000 triggers red chain.
#maxpacketloss (amount in %)	#maxpacketloss 50	Set the maximum accepted packet loss
#maxping (time in ms)	#maxping 250	Set the maximum accepted ping
#dctimeout (time in sec)	#dctimeout 60	Set the disconnect timeout

Monitoring/Analysis

Command	Example	Description
#monitor (interval in sec)	#monitor 1	Shows performance information of the server. Interval 0 means to stop monitoring. Values description Traffic G Guaranteed messages NG Non-Guaranteed messages Player info L lobby R role selection B briefing G in-game D debriefing
#monitords (interval in sec)	#monitords 1	1.64 Shows performance information in the dedicated server console. Interval 0 means to stop monitoring.
#debug (interval in sec)	#debug 30	Default interval is 10 seconds.
#debug on (command)	#debug on Console #debug on TotalSent #debug on UserSent #debug on UserInfo #debug on UserQueue #debug on JIPQueue	The available commands are: Console - All server console prints, are forwarded to your client. Send to submitter what's on server console. Works as DebugAnswer for all writes into the console. TotalSent - Every debug interval, tells you the bits per second, msg per second. Send/Receive for the whole server UserSent - Every debug interval, tells you the bits per second, messages per second. Send/Receive statistics for every player UserInfo - Every debug interval, some statistics, for every player UserQueue - Every debug interval, Info about how many bytes/messages are currently queued up, per player JIPQueue - Every debug interval, the number of messages in JIP queue's Each command can be disabled by the use of the off parameter e.g. #debug off UserSent Each command differs a bit - some output to screen, some to log file etc. See below for example output. You need some debugger capable of catching OutputDebugString running on the client machine. A very small and easy to use called DebugView is available on the SysInternals website. You launch this debugger, then launch ARMA client, connect to the server, and issue any of the commands.
#debug off <OPTION>	#debug off TotalSent	Disables the specific debugging <OPTION>. See available options above.
#debug off	#debug off	Disables all debugging options.
#debug checkFile (PATH\TO\FILE.PBO)	#debug checkFile Expansion\Dta\ui.pbo	Trigger integrity check on filename.
#debug von	#debug von	Triggers VoN debug mode. Outputs into logFile defined in server config as e.g. logFile = "server_console.log";. See below for example output.
#debug limitOut bitsPerSecond	#debug limitOut 100000	Change bandwidth limit (in bits per second). Must be larger than 0. You get response message: "Outgoing bandwidth limited to %d B/s (%d bps) per client".

Performance Profiling

Command	Example	Description
PROF #captureframe		The current frame on the server is captured and written to a log file in the same directory as the .rpt file. See diag_captureFrameToFile for more info. ⓘ Until 2.20 PROF on client was required to trigger #captureFrame command on server. Starting 2.20 they can mismatch. You can trigger #captureFrame on a PROF server (always required), coming from a PERF client for example.
PROF #captureslowframe scope, threshold, frameOffset, numberOfSlowFrames to capture	#captureSlowFrame total 0 0 0 #captureSlowFrame total 0.3 0 1 equals to diag_captureSlowFrame ['total', 0.3]	Captures the current frame on the server if it exceeds the set threshold in seconds and get written to a log file in the same directory as the .rpt file. See diag_captureSlowFrame for more info.
DIAG #logEntities		Creates a log file containing the list of all game entities in scene. See logEntities for more info.
DIAG PROF #exportJIPqueue		Creates a log file containing an overview on all JIP (network) messages currently in the JIP queue. See exportJIPMessages for more info.
#debug jipPerf	#debug jipPerf	Dumps the JIP queue in your client's chat. It might also print to client/server RPT? (TBC). It is the top part of what exportJIPMessages does.

BE is for BattlEye - BE has its own messaging.

Arma 3 #exec Notes

See Arma 3: Server Side Scripting.

In Arma 3 #exec kick and #exec ban commands require quotes (string) for Name, UID or Player#. To do this for the UID or Player#, use format command to turn the user ID into a string.

#exec kick "5"
#exec ban "imah4x0r"
#exec kick "938679499494"

#kick command can still be used either way:

#kick imah4x0r
#kick "imah4x0r"

In case of banning, a ban.txt file containing a list of banned UIDs is created in Arma 3's root directory. To unban a user by UID (UID is the only option) or to clear the ban.txt:

#exec unban "98749837498374"
#exec clearbans
