Connection & RCON Troubleshooting · Operation: Harsh Doorstop

No dedicated-server hardware requirement was ever published (only client specs: 8 GB minimum, 16 GB recommended, which cannot be reused). The circulating four-tier RAM table names no hosting provider and cannot be traced, so this site lists it as an untraceable claim rather than adopting it as a spec. Every field is editable, blank means not counted rather than zero, and the maths is a reproducible base plus per-player times players

Game 7777/UDP, query 27005/UDP, RCON 7779/TCP, plus the 7778/TCP that LinuxGSM uses (D1) - the ecosystem RCON client README states all four must be forwarded. AMP port table does not register the game port at all, which is why panels show only one port. Any cross-instance port collision refuses the whole plan instead of silently changing values

Four platforms (ufw / firewalld / iptables / netsh). By default only the game and query UDP rules are emitted; both RCON ports are explicit opt-ins that come with a risk warning about handing the console to the internet plus an optional source IP/CIDR restriction. RCON is Source RCON over TCP, so no UDP rule is produced for it

Pick the stable track app_update 950900 (owning client 736590) or the development track app_update 1316480 (owning client 1307180, the closed beta); the development track comes with the executable rename and symlink steps verbatim from AMP updates.json because the two tracks ship different binary names. Optional Workshop download (IDs validated as digit strings). Backups emit copy commands only, preceded by a stop-the-server warning, and never a delete command

Options are joined with question marks (that is AMP delimiter), the leading HarshDoorstop positional argument can be switched between the two upstream camps (D3), the bind IP is emitted only when a concrete address is given and its casing is selectable (D2, never hardcoded to 0.0.0.0), RCON is off by default and emits -EnableRCON with a placeholder password when enabled (D4), map and faction dropdowns share one source with free input, blank ticket counts are omitted (they are per-map, so no global default), and there are gates at 33 and 65 players

Eighteen keys across five Script sections, sourced primarily from the real file in the LinuxGSM official config-template repository, with the six RCON keys pinned by the Unreal Header Tool dump (whose uint16 and uint32 types give the validation ranges). Two same-named Password keys are told apart by section-qualified ids. Full file and diff fragment come from one value function, any violation refuses the whole output, credentials are always placeholders, and the paste precheck names eight issue classes reporting only len=

RCON is standard Source RCON over TCP (proved by the client source packet format and the AMP description), so mcrcon-class tools work directly; it only listens with -EnableRCON or bEnabled=True. Commands are tiered: A for hits in the server dump, B+ for the hosting provider dedicated docs, C for single-source items marked unverified. The core rule is that the two entry points use opposite prefixes: the in-game console needs the admin prefix, an RCON client does not. The two camps on ban argument order are shown side by side (D15)
