This guide covers the iosserver module in AlphaGSM.

iosserver is currently ENABLED (AUTH) on the documented Ubuntu 24.04 Linux baseline. GitHub keeps one Docker-default auth-gated lifecycle entry; it does not attempt the known-crashing public branch as a process test.

Requirements

Developer Notes

Run File

Executable: srcds_run
Location: <install_dir>/srcds_run
Engine: Source
SteamCMD App ID: 673990

Current validation status: ENABLED (AUTH). AlphaGSM targets the dedicated tool app 673990, but the supported sdk2013 branches iosoccer2025 / beta are not anonymously accessible. Fresh SteamCMD probes against the dedicated tool app still return ERROR! Failed to set beta 'iosoccer2025' for anonymous login, while the public branch continues to crash on Linux after startup. The supported path is authenticated Steam or SteamCMD access to the dedicated tool branch before setup.
