RCON (Telnet) is enabled by default. You only need to set a password. The connection port is shown on your server's main page and is always the server port + 3.
- Open Configuration Files in the game panel.
- Open the Configuration Editor for serverconfigmain.xml.
- Scroll down to the Admin Interfaces section, where you can change the Telnet password.
- Set the menu option to Enable Telnet and enter the required password.
- Save the changes. They will take effect the next time the server starts.
Alternatively, use the Text Editor and edit the following values:
<property name="TelnetEnabled" value="true"/> <!-- Enable/Disable the telnet -->
<property name="TelnetPassword" value="y06W0Go0IX"/> <!-- Password to gain entry to telnet interface. If no password is set the server will only listen on the local loopback interface -->
<property name="TelnetFailedLoginLimit" value="10"/> <!-- After this many wrong passwords from a single remote client the client will be blocked from connecting to the Telnet interface -->
<property name="TelnetFailedLoginsBlocktime" value="10"/> <!-- How long will the block persist (in seconds) -->
