How to Use RCON on Your Arma Reforger Server

With RCON (Remote Console) you can manage your server remotely without being in the game yourself – e.g. list, kick or ban players and restart the scenario. Arma Reforger uses the BattlEye RCon protocol for this, which communicates over UDP.

Enable RCON

RCON only starts when an RCON password is set.

1. Open dashboard
   Open the dashboard of your server.

2. Open settings
   Navigate to the Settings.

3. Enter RCON password
   Enter a password in the RCON Password field.

4. Restart the server
   Save the setting and restart your server.

RCON credentials

You need three pieces of information to connect:

• Address
  The IP address of your server (without port), e.g. 203.0.113.10.

• RCON port
  You can find the RCON port in the dashboard in the port overview. The port is assigned by us and cannot be changed.

• Password
  The password from the RCON Password field in the Settings.

Set RCON permissions

On your server, RCON is set to the monitor permission by default. This only lets you run commands that do not change the server's state, e.g. #players. If you also want to kick or ban players over RCON, change the permission to admin.

1. Stop the server
   Stop your server via the dashboard.

2. Connect via SFTP
   Connect to your server via SFTP.

3. Open config.json
   Open the file config.json in the root directory of your server and find the "rcon" section.

4. Change permission
   Change the value of "permission" from "monitor" to "admin":

   "rcon": {
     "permission": "admin",
     "blacklist": [],
     "whitelist": []
   }
   

   The snippet only shows the relevant entries. Leave the other entries in the "rcon" section unchanged.

5. Start the server
   Save the file and start your server.

Restrict commands with blacklist and whitelist

In the "rcon" section you can also define which commands are allowed over RCON. Both entries are lists of commands and are empty by default. You also edit these entries in config.json via SFTP while your server is stopped.

Number of simultaneous RCON connections

With the optional "maxClients" entry in the "rcon" section you define how many RCON clients may be connected at the same time. Allowed values are 1 to 16, the default is 16. You edit config.json for this the same way as when changing the permission: stop the server, edit the file via SFTP, start the server.

"rcon": {
  ...
  "maxClients": 4
}

Connect with RCON

1. Open RCON tool
   Open an RCON tool that supports the BattlEye RCon protocol.

2. Enter connection details
   Enter the RCON credentials: address, RCON port and password.

3. Run commands
   Once connected, you can run the commands from the following table.

RCON commands

The player ID (5 in the examples) is shown by #players. It only works while the player is connected to the server. If the player is no longer online, ban them by their identityId instead.

Examples:

#ban create 5 3600 Teamkilling
#ban create 5 0
#ban list 2
