What you need
The shop server
- One PC running Windows 10 or 11, 64-bit. Your counter PC is fine.
- 4 GB of RAM and about 10 GB of free disk space.
- A fixed address on your network is best: set a DHCP reservation in your router so it doesn't change. PCs find the server by themselves, but a fixed address avoids surprises.
Customer PCs
- Windows 10 or 11, 64-bit.
- On the same network as the server (wired or Wi-Fi).
- For a proper lockdown, a standard (non-administrator) Windows account for players. See kiosk mode.
Network
The server uses these ports. The installer opens them in Windows Firewall for you:
| Port | What it's for |
|---|---|
| 8080 (TCP) | The staff app and the API the PCs use |
| 8081 (TCP) | Instant updates to PCs (real-time connection) |
| 47800 (UDP) | Lets PCs find the server automatically |
The database (port 3307) only listens on the server itself.
Internet
Only for activating and renewing your license, and downloading updates. CafeOS keeps working without it.
