An ETS2 server does not know which map, DLC and mods to run until you tell it. That information lives in server_packages.sii and server_packages.dat, and both files are produced by your own copy of the game.
1. Turn on the developer console
- On your PC, open
config.cfgin your Documents folder for Euro Truck Simulator 2. - Set
uset g_developer "1"anduset g_console "1". - Save the file.
2. Load the profile the server should mirror
- Start the game.
- Enable exactly the map DLC and mods you want the server to run.
- Load into the world, not just the main menu.
3. Export
- Press ~ to open the console.
- Type
export_server_packagesand press Enter. - The game writes
server_packages.siiandserver_packages.datinto your Euro Truck Simulator 2 folder in Documents.
4. Upload both files
- Stop the server in the Game Panel.
- Open the Files tab and upload both files next to
server_config.sii, replacing the existing pair. - Start the server and watch the console as it loads them.
5. Rules that save you a ticket
- Everyone joining needs the same map DLC the packages were exported with.
- Add or remove a DLC or mod and you must export and upload again. The server will not notice on its own.
- Export again after a game update. The files are tied to the game version.
- Upload both files. Sending only the
.siiis the most common mistake.
If the server refuses to start after an upload, put the previous pair back and open a ticket with the console output.
