# Project Zomboid Project Zomboid is the ultimate in zombie survival. Alone or in MP: you loot, build, craft, fight, farm and fish in a struggle to survive. A hardcore RPG skillset, a vast map, a massively customisable sandbox and a cute tutorial raccoon await the unwary. So how will you die? ## Configuration Project Zomboid creates Backup on Server Start by copying its SaveData into Temp and then zipping it up, after a few days these files are so large that your Server will fail on Startup with Error: `java.util.concurrent.ExecutionException: java.io.IOException: No space left on device`. Either disable Backups in the Project Zomboid Server Settings via `BackupsOnStart=false` or increase the `tmpfs_size` in your wings config.yml configuration file. ## Server Ports Project Zomboid requires one port for game data and one port for Steam. ```log > *** SERVER STARTED ****. > *** Steam is enabled. > Server is listening on port 16261 (for Steam connection) and port 16262 (for UDPRakNet connection). > Clients should use 16261 port for connections. ``` | Port | default | |-------------|---------| | DefaultPort | 16261 | | UDPPort | 16262 |
