Dedicated server guide

No More Room in Hell

Manage nmrihserver with AlphaGSM. Choose a runtime supported by the recorded module capabilities.

Recorded lifecycle pass · Support evidence: 2026-10-16.

Anonymous Workshop Process and Docker load passed for public dedicated-server content. Mod installation explains add, apply, and cleanup.

Build setup commands

Runtime familysteamcmd-linux

Declared runtimes: Docker or a Linux host process.

Network bindings

27015/UDP, 27015/TCP, clientport/UDP, sourcetvport/UDP. Named port values remain unknown; review the game guide and configuration for additional requirements.

Mods and plugins

For Workshop content, use the setup builder with an actual game-compatible item ID; review supported content types in the guide. Anonymous Steam Workshop content for this module passed both process and Docker load. After setup, record an item with mod add workshop using a numeric ID or Steam Workshop URL, then run mod apply.

Backup hook

A module-specific backup hook is declared. Review the game guide for its scope, restore procedure and shutdown requirements.

This guide covers the nmrihserver module in AlphaGSM.

nmrihserver is currently PASSED on the documented Ubuntu 24.04 Linux baseline. The current GitHub integration lane still exercises both process and Docker runtime selection, and the validated Linux lifecycle stays aligned across both backends while local runs remain process-backed by default unless you opt into the Docker backend.

Requirements

screen
SteamCMD runtime libraries (lib32gcc-s1, lib32stdc++6)
Python packages from requirements.txt

Quick Start

Create the server:

alphagsm mynmrihser create nmrihserver

Run setup:

alphagsm mynmrihser setup

Start it:

alphagsm mynmrihser start

Check it:

alphagsm mynmrihser status

Stop it:

alphagsm mynmrihser stop

Setup Details

Setup configures:

the game port (default 27015)
the install directory
the executable name
SteamCMD downloads the server files
default configuration and backup settings

Useful Commands

alphagsm mynmrihser update
alphagsm mynmrihser backup

Notes

Module name: nmrihserver
Default port: 27015

Server variables

After create nmrihserver, inspect or change these with set:

alphagsm myserver set --list
alphagsm myserver set KEY --describe
alphagsm myserver set KEY VALUE

Key	Aliases	Type	What it does
`map`	gamemap, startmap, level, worldname	string	The currently selected map or level. Example: `nmo_broadway`.
`maxplayers`	users	integer	Maximum number of player slots. Example: `8`.
`port`	gameport	integer	The primary game port. Example: `27015`.
`rconpassword`	rconpass, querypassword, query_administrator_password	string	Remote console password for administrative access. Stored as a secret.
`servername`	hostname, name	string	The server's public name shown to players. Example: `AlphaGSM No More Room in Hell`.
`serverpassword`	sv_password, password	string	Password required for players to join the server. Stored as a secret.

Maps and Mods

Map directory: nmrih/maps/
Mod directory: nmrih/addons/
Workshop support: Anonymous dedicated map items by ID/URL and same-game collections.
Mod notes: AlphaGSM now supports manifest, direct archive url, gamebanana, and moddb addon sources for this server through the shared Source addon flow. The built-in manifest currently includes metamod and sourcemod. mod cleanup removes only AlphaGSM-tracked addon files and keeps cache/state under .alphagsm/mods/nmrih/.
Map install: Copy .bsp files into nmrih/maps/ and add to nmrih/cfg/mapcycle.txt.
Mod install: Copy addon folders into nmrih/addons/.

Workshop multiplayer maps

Add a public dedicated map item or a Steam Community item URL. Collections expand into a snapshot of same-game item IDs:

alphagsm myserver mod add workshop 3514998402
alphagsm myserver mod add workshop-collection YOUR_COLLECTION_ID
alphagsm myserver mod apply
alphagsm myserver set map nmo_lotr_mines_of_moria_v3
alphagsm myserver start

SteamCMD downloads these maps anonymously using the game's AppID 224260. AlphaGSM validates Source BSP headers and map-family names, then publishes map assets into nmrih/maps/ and approved native asset directories. Packages must contain dedicated maps; client-only reskins and other-game maps are rejected. The original archive-backed addon commands remain available.

Apply and clean up while the server is stopped. AlphaGSM refuses unowned file collisions and removes only unchanged files recorded by its Workshop map owner. If you edit a managed asset, restore its installed bytes before reapplying or cleaning up. Download caches remain in .alphagsm/workshop/.

This activates native server map assets. Players must subscribe to the matching Workshop item or receive the required map assets through your own supported content delivery configuration. AlphaGSM does not configure automatic Workshop client delivery for these maps.

The public Mines of Moria fixture was checked against Valve metadata for AppID 224260 on 2026-10-13. Process and Docker Workshop lifecycles passed on 2026-10-15 in CI run 38748333313, with real A2S reporting nmo_lotr_mines_of_moria_v3, verified shutdown and owned-asset cleanup. Opt-in lifecycle tests load this custom map through the running engine and require real A2S info --json to report its name; file staging alone cannot pass the load check.

The checks accept ALPHAGSM_NMRIHSERVER_WORKSHOP_COLLECTION and ALPHAGSM_NMRIHSERVER_WORKSHOP_MAP overrides. Smoke uses NMRIH_WORKSHOP_COLLECTION and NMRIH_WORKSHOP_MAP. Process and Docker checks use the same AlphaGSM lifecycle; Docker uses the steamcmd-linux image and Source console terminal relay. Set ALPHAGSM_BACKEND_DOCKER_IMAGE_STEAMCMD_LINUX to the branch-local image tag when validating repository changes.
