How to Add Mods to Your ETS2/ATS Server

Installing Mods on Your ETS2/ATS Server

To run mods on your ETS2 or ATS server, you’ll need to export the mod list from your game and upload two specific files to your server.

Follow the steps below:

Step 1: Prepare Mods on Your Local Game

1. Launch ETS2 or ATS through Steam.
2. Go to the Mod Manager and move your desired mods into the "Active" section.
3. Load into a convoy session to confirm that everything works properly.
4. Open the developer console (enable it by editing config.cfg and setting g_developer "1" and g_console "1").
5. In the console, type: export_server_packages
6. This will generate two files in your Documents folder:

• server_packages.sii
• server_packages.dat

These files contain all the necessary mod references for your server.

Step 2: Upload Mod Files to the Server

1. Go to the RocketNode Game Panel and stop your server.
2. Open the File Manager or access the server via SFTP.
3. Navigate to the appropriate directory:

• For ETS2: .local/share/Euro Truck Simulator 2/
• For ATS: .local/share/American Truck Simulator/

4. Upload both server_packages.sii and server_packages.dat into this folder.

Step 3: Start Your Server

Once the files are uploaded, return to the panel and start your server. The mods should now load on launch.

Important Notes

• If you change your active mods locally, you must run export_server_packages again and re-upload the new .sii and .dat files to the server.
• Clients connecting to the server must have the same mods installed and in the same load order, or they will not be able to join.
• The server does not automatically download mods for players.
