Hardcore medieval sandbox (standalone Wurm Online) · Sandbox / Medieval / Hardcore
Anonymous install of appid 402370 (public = the 1.9.1.6-era build of 2019-04-09; optional -beta beta for 1.9.2.7), the Linux headless trio (libswt-gtk-3-java / Xvfb / DISPLAY=:99), the steamclient.so to nativelibs fix, the LGSM first-run dist/* copy note (D2) and a systemd unit (SIGINT stop, matching LGSM stopmode=2). The version freeze is stated as-is
Address builder and validator for the in-game server browser (Internet / LAN tabs) and direct connect via ip:externalport (default 3724 TCP). steam://connect behaviour on WU is unverified, so this site does not generate it (D3)
Triage tree sourced from the official docs: not listed (query ports 27016-27030 UDP unforwarded - the server still starts but is LAN-tab only), [S_API FAIL] (steamclient.so to nativelibs), headless hangs (SWT + Xvfb), Linux binding 127.0.0.1, "You can not log on..." (IS_GAME_SERVER), version mismatch (client and server must both be 1.9.x)
One stop for the store page, official docs, the time/calendar wiki, the server mod loader and the panel ecosystem (LinuxGSM/AMP/Pelican/Docker). WU has no Steam Workshop - mods are file and loader based
Java heap anchored on the AMP default 2048m (editable) plus editable off-heap overhead (labelled unofficial), disk (install size plus measured world sqlite growth) and editable per-player bandwidth. Cross-checked against LOW.MS commercial RAM tiers (accessed 2026-09-27). No official hardware table exists
Anchor-based conversion: enter one in-game /time reading plus the real-world moment it was taken, then convert any Wurm date to real time and back by pure arithmetic, get the current season and the next season boundary, look up the official 12-Starfall harvest table (verbatim, plus/minus 2 weeks disclaimer), and convert tiles/km/dirts plus triangulation height. No absolute epoch is claimed (never published)
All four port groups: 3724 TCP client traffic, 27016-27030 UDP Steam queries (single-port flavour shown alongside, D1), 8766 TCP/UDP general Steam communication (D7), and 7220/7221 TCP RMI which is cluster-only and officially must never be exposed. Multi-instance allocator with two strategies (OGP offsets vs fixed defaults, D4); out-of-range or colliding plans are rejected wholesale
Rules for ufw / firewalld / iptables / Windows netsh: 3724 TCP plus the query port (whole range or single port, defaulting to the official range) plus 8766 TCP/UDP. RMI 7220/7221 never appears in generated rules - official wording: "Do not under any circumstances open these ports to external access"
Anonymous install of appid 402370 (public = the 1.9.1.6-era build of 2019-04-09; optional -beta beta for 1.9.2.7), the Linux headless trio (libswt-gtk-3-java / Xvfb / DISPLAY=:99), the steamclient.so to nativelibs fix, the LGSM first-run dist/* copy note (D2) and a systemd unit (SIGINT stop, matching LGSM stopmode=2). The version freeze is stated as-is
A form for all 15 CLI arguments from the official docs: world directory (root vs dist/ flavours, D2), kingdom enum 0-4, true/false booleans, automatic quoting of servername with spaces (official rule). adminpwd / serverpassword render as placeholders - this site never fills them in. Any violation rejects the whole output. Includes a correction note on the fabricated "Server.cfg" spreading in CN content farms
All 40 non-Reserved keys from the official docs (Java Properties syntax): full file and diff fragment share one code path, and any violation rejects the whole output. The 24 Reserved keys (including credential-shaped ones like DB_PASS) are never emitted; the paste pre-check flags unknown-key / bad-bool / bad-int / reserved-touched and reports only the length of credential values, never the value. Gameplay Tweaks live in the world database/GUI, not in wurm.ini, so this site does not generate them

LaunchConfig.inidist/Creative/wurm.inidist/Adventure/wurm.iniThe official query-port wording is the whole UDP range 27016-27030 (the single value 27016 used by LinuxGSM/Docker is shown alongside, D1) - confirm with hosts that only hand out one port. 8766 TCP/UDP is officially required for Steam communication (LinuxGSM omits it and still works, D7). RMI 7220/7221 are cluster-only and officially must never be exposed - any tutorial telling you to forward them is wrong. Version freeze: LIVE stopped at 1.9.1.6 (2019-04-09) and beta at 1.9.2.7 (2020-01-21); client and server must match. WU has no Steam Workshop; server mods go through WurmServerModLauncher.
