This guide covers the ohdserver module in AlphaGSM.

ohdserver is currently PASSED on the documented Ubuntu 24.04 Linux baseline. The checked-in GitHub validation path for this server is Docker-first through the shared steamcmd-linux runtime, with A2S query / info on the managed queryport.

query and info resolve the runtime's reachable host, including Docker's published endpoint when AlphaGSM runs in a separate container. This routing correction is awaiting replacement GitHub CI validation.

Requirements

docker for the validated branch-local steamcmd-linux runtime path
SteamCMD runtime libraries (lib32gcc-s1, lib32stdc++6)
Python packages from requirements.txt

Quick Start

Create the server:

alphagsm myohdserve create ohdserver

Run setup:

alphagsm myohdserve setup

Start it:

alphagsm myohdserve start

Check it:

alphagsm myohdserve status

Stop it:

alphagsm myohdserve stop

Setup Details

Setup configures:

the game port (default 7777)
the A2S query port (default 27015)
the install directory
SteamCMD downloads the server files

Useful Commands

alphagsm myohdserve update
alphagsm myohdserve backup

Notes

Module name: ohdserver
Default port: 7777
Default query port: 27015
Validated Linux support path: native Linux dedicated payload on the shared steamcmd-linux runtime image

Server variables

After create ohdserver, 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
`dir`	—	string	Install directory for the server.
`exe_name`	—	string	Server executable filename.
`port`	gameport	integer	The game port for the server. Example: `7777`.
`queryport`	—	integer	The query port for the server. Example: `27015`.
`servername`	hostname, name	string	The advertised server name. Example: `AlphaGSM Server`.
