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 Arma 3 logo black.png1.66 Shuts down and restarts the server immediately
#shutdownaftermission Arma 3 logo black.png1.72 Shuts down the server after mission ends
#restartserveraftermission Arma 3 logo black.png1.72 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"
Arma 3 logo black.png2.18 #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
Arma 3 logo black.png2.18 #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 Arma 3 logo black.png1.64 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
Arma 3 logo black.pngPROF #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 Arma 3 logo black.pngPROF on client was required to trigger #captureFrame on server. Starting with Arma 3 logo black.png2.20 they can mismatch. You can trigger #captureFrame on a Arma 3 logo black.pngPROF server (always required), coming from a Arma 3 logo black.pngPERF client for example.
Arma 3 logo black.pngPROF #captureslowframe scope, threshold, frameOffset, numberOfSlowFrames to capture #captureSlowFrame sLoop 0 0 0

#captureSlowFrame sLoop 0.033 0 1
#captureSlowFrame sLoop 33ms
#captureSlowFrame sLoop 30fps

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.

Note: #captureSlowFrame sLoop 0.033 0 1 equals to diag_captureSlowFrame ['sLoop', 0.033]. See diag_captureSlowFrame for more info.

Arma 3 logo black.pngDIAG Arma 3 logo black.pngPROF #logEntities Creates a log file containing the list of all game entities in scene. See logEntities for more info.
Arma 3 logo black.pngDIAG Arma 3 logo black.pngPROF #exportJIPqueue Creates a log file containing an overview on all JIP (network) messages currently in the JIP queue. See exportJIPMessages for more info.
Arma 3 logo black.png2.20 Arma 3 logo black.pngDIAG Arma 3 logo black.pngPROF #logremains Log remains collector entities into a file in the RPT directory. See also cdiag_remainsCollector -1 and the #logremains server command.
#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.

Arma 3 #exec Notes

Arma 3

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
