This guide covers the sfcserver module in AlphaGSM.

sfcserver 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 staged-ModDB-content prerequisite, 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
The official SourceForts Classic 1.0 RC7 (Fix) 7z from ModDB, extracted under <install_dir>/sfclassic/

Support Status

sfcserver is supported in ENABLED (BYO) mode. AlphaGSM installs Steam app 244310 from the anonymous previous2021 branch. That legacy SDK 2013 dedicated branch is the 32-bit launcher this game can start. The public branch of the same app does not finish startup. The install still needs the official SourceForts Classic 1.0 RC7 (Fix) tree from ModDB. Leave the 1.1b3 Linux64 pre-release unstaged; this depot does not ship srcds_linux64. App 244310 publishes bin/*_srv.so. prestart copies those onto the unsuffixed names srcds_linux loads, restores the launcher execute bit, and writes sv_hibernate_when_empty 0. A local process start answered A2S on UDP 58844 (map sf_astrodome, 0/32). The A2S hostname was Sourceforts Classic 1.0 [BUILD]. The process was stopped and that UDP port was free. Docker was not run.

Quick Start

Create the server:

alphagsm mysfcserve create sfcserver

Run setup:

alphagsm mysfcserve setup

Start it:

alphagsm mysfcserve start

Check it:

alphagsm mysfcserve status

Stop it:

alphagsm mysfcserve 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

Before start, download SourceForts Classic 1.0 RC7 (Fix) from the official ModDB file page and extract the resulting sfclassic/ tree so <install_dir>/sfclassic/maps/sf_astrodome.bsp exists. If setup or start reports an ENABLED (BYO) requirement, app 244310 on previous2021 is still only the SDK scaffold.

Useful Commands

alphagsm mysfcserve update
alphagsm mysfcserve backup

Notes

Module name: sfcserver
Default port: 27015

Maps and Mods

Map directory: sfclassic/maps/
Mod directory: sfclassic/addons/
Workshop support: No
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/sfclassic/.
Current status: Supported in ENABLED (BYO) mode. Anonymous SteamCMD app 244310 on previous2021 provides the 32-bit SDK scaffold, and the official ModDB 1.0 RC7 (Fix) tree provides sfclassic/. Local process A2S was validated on UDP 58844 (map sf_astrodome, 0/32) and the server was stopped. Docker was not rerun.
Map install: Copy .bsp files into sfclassic/maps/ and add to sfclassic/cfg/mapcycle.txt.
Mod install: Copy addon folders into sfclassic/addons/.

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.
