This guide covers the sof2server module in AlphaGSM.

sof2server is currently ENABLED (BYO) on the documented Ubuntu 24.04 Linux baseline. The current GitHub integration lane still exercises both process and Docker runtime selection around that owned-dedicated-tree prerequisite, while local runs remain process-backed by default unless you opt into the Docker backend.

Requirements

screen
an owned Soldier of Fortune 2 dedicated-server tree
32-bit runtime compatibility for the original server binary

Quick Start

alphagsm mysof2 create sof2server
alphagsm mysof2 setup
alphagsm mysof2 start
alphagsm mysof2 status
alphagsm mysof2 stop

sof2server is supported in ENABLED (BYO) mode. Before setup or start, copy an owned SOF2 dedicated server tree into your chosen <install_dir>/ so <install_dir>/sof2ded exists.

Suggested flow:

alphagsm mysof2 create sof2server
alphagsm mysof2 setup -n 20100 /path/to/sof2server
## copy the owned SOF2 dedicated server files into /path/to/sof2server/
alphagsm mysof2 start

Notes

Module name: sof2server
Install mode: ENABLED (BYO) server files
Default port: 20100
Query/info protocol: quake on the game port
Executable: ./sof2ded

Server variables

After create sof2server, inspect or change these with set:

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

This module does not declare schema-backed keys. set --list after create is still the live source of truth.

Developer Notes

AlphaGSM follows LinuxGSM's launch defaults for sof2ded, including sv_punkbuster 0, dedicated 2, net_ip, net_port, +exec base/<server-name>.cfg, and the default map mp_shop.
LinuxGSM marks SOF2 as an idTech3-family server with protocol-quake3, so AlphaGSM uses the existing Quake UDP query/info path.
Automated install is not provided because no authoritative LinuxGSM-backed download path was identified for this legacy server.

BYO file helper

Inspect this game's required files, source instructions and destinations with alphagsm <server-name> assets requirements; check the declared files with alphagsm <server-name> assets check. File checks do not establish game readiness. This helper checks known sentinels only and directs you to stage the complete compatible distribution manually; managed import is unavailable for this recipe. See BYO files and private SteamCMD acquisition.
