This guide covers the coduoserver module in AlphaGSM.

coduoserver 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-base-assets prerequisite, while local runs remain process-backed by default unless you opt into the Docker backend.

Requirements

screen
owned base Call of Duty multiplayer assets that include main/pak0.pk3 or main/default_mp.cfg
Python packages from requirements.txt

Quick Start

Create the server:

alphagsm mycoduoser create coduoserver

For an owned Steam copy, sign in once and let setup acquire the declared files:

alphagsm steam-auth login owned your_steam_username
alphagsm mycoduoser setup --auth-profile owned

Enter credentials only at the local SteamCMD prompts. For an existing local Steam library, use setup --steam-dir /path/to/SteamLibrary/steamapps instead. Local process setup with an entitled profile was validated on 2026-10-16. Query and info use Quake UDP getstatus on the game port. Docker was not rerun.

Start it:

alphagsm mycoduoser start

Check it:

alphagsm mycoduoser status

Stop it:

alphagsm mycoduoser stop

Setup Details

Setup configures:

the game port (default 28960)
the install directory
downloads and extracts the server archive
still requires copied base Call of Duty multiplayer assets before the server can finish startup

coduoserver is supported in ENABLED (BYO) mode. AlphaGSM installs the dedicated binary for Call of Duty: United Offensive, but the archive still depends on owned base Call of Duty multiplayer files that are not bundled.

If using setup without an asset source or saved profile, before start copy the required files from a legitimate base Call of Duty installation into the AlphaGSM server tree:

<install_dir>/main/pak0.pk3
<install_dir>/main/default_mp.cfg

A manual tree also needs the expansion PK3s under uo/, including the multiplayer map maps/mp/mp_uo_stanjel.bsp. The default start map mp_brecourt is stored in the base main PK3s. Authenticated setup downloads base app 2620 and expansion app 2640, keeps the English multiplayer PK3s, and drops client executables and non-English localization PK3s.

Manual-copy alternative:

alphagsm mycoduoser create coduoserver
alphagsm mycoduoser setup
cp /path/to/cod/main/pak0.pk3 <install_dir>/main/
cp /path/to/cod/main/default_mp.cfg <install_dir>/main/
alphagsm mycoduoser start

Useful Commands

alphagsm mycoduoser update
alphagsm mycoduoser backup

Notes

Module name: coduoserver
Default port: 28960
Current blocker for anonymous installs: the dedicated archive still depends on owned base Call of Duty assets such as main/pak0.pk3 or main/default_mp.cfg

Server variables

After create coduoserver, 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.
`download_name`	—	string	Cached archive filename.
`exe_name`	—	string	Server executable filename.
`hostname`	servername, name	string	The advertised server name.
`moddir`	—	string	The active Call of Duty: United Offensive mod directory. Example: `baseq3`.
`port`	gameport	integer	The game port for the server. Example: `27960`.
`startmap`	map, gamemap, level, world	string	The startup map.
`url`	—	string	Download URL for the server archive.

Developer Notes

Run File

Executable: coduoded_lnxded
Location: <install_dir>/coduoded_lnxded
Engine: Custom

Server Configuration

Config file: <moddir>/server.cfg (default uo/server.cfg)
set servername, set moddir, and set map rewrite <moddir>/server.cfg immediately through the schema-backed config-sync path.
Setup stages the upstream gcc 3.2 libraries beside coduo_lnxded and starts it with LD_LIBRARY_PATH=., fs_basepath ., and fs_homepath . so the dedicated server does not use ~/.callofduty.
Owned base assets still required: main/pak0.pk3, main/default_mp.cfg
Copy target before first start: <install_dir>/main/
Template: See server-templates/coduoserver/ if available

Maps and Mods

Map directory: <install_dir>/<moddir>/
Mod directory: <install_dir>/<moddir>/
Workshop support: No

Mod Sources

Call of Duty: United Offensive supports AlphaGSM-managed direct url mod sources for content-only .pk3 payloads.

Supported payload shapes:

a direct .pk3 URL
an archive containing bare .pk3 files at the archive root
an archive containing <moddir>/<name>.pk3

AlphaGSM installs approved .pk3 content into the active moddir directory, tracks only the files it owns, and adds that active content directory to the managed backup targets.

Examples:

alphagsm mycoduoser mod add url https://example.com/mappack.pk3
alphagsm mycoduoser mod add url https://example.com/custom-content.zip
alphagsm mycoduoser mod apply
alphagsm mycoduoser mod cleanup

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. The preferred Steam-owned path is alphagsm steam-auth login owned <username>, then alphagsm <server-name> setup --auth-profile owned. Setup remembers the profile name and fetches missing required files before installing the engine. Use setup --steam-dir /path/to/SteamLibrary/steamapps to import from an existing Steam library instead. Direct file acquisition remains available through assets fetch steam-owned --auth-profile owned. Authenticated downloads remain unverified here. See BYO files and private SteamCMD acquisition.
