Server notes

Factorio has no Steam dedicated server to pull — you download the server from factorio.com, where a dedicated headless build omits graphics, sound and the Xlib/libGL/asound dependencies for pure server machines. Steam-hosted games still use 34197. The only port is **UDP 34197** (Factorio is UDP-only and builds its own reliable-delivery layer on top to handle loss and reordering), plus 27015/TCP for RCON if you want it. One easily missed trap: if your router randomises the source port on packets leaving 34197 (NAT rewriting), players simply cannot connect, and that behaviour has to be disabled on the router. Configuration is three JSON files — map-gen-settings.json (map size, ore patch frequency and size), map-settings.json (pollution spread, biter expansion and evolution) and server-settings.json (server name, visibility, player cap, autosave_interval, RCON password) — with the first two only applying when you create a map via --create. The server **requires** an existing save, so the flow is factorio --create saves/main.zip to generate, then factorio --start-server saves/main.zip --server-settings ./data/server-settings.json to host. Headless mode auto-pauses with no players connected unless you set auto_pause = false in server-settings.json. Every instance must run identical game and mod versions or clients cannot join. Performance is about single-core clock rather than core count, and the bigger the factory the harsher it gets. Use autosave_interval 10 and autosave_slots 15; a large save alone can be hundreds of megabytes, so budget 30–100 GB of disk. Never run it in a bare SSH session — use systemd, tmux or screen. Admins go in config/server-adminlist.json and the whitelist in server-whitelist.json.
