This guide covers the bannerlordserver module in AlphaGSM.

Support Status

bannerlordserver is supported in ENABLED (AUTH) mode.

AlphaGSM can:

manage the dedicated server lifecycle
install the Linux dedicated payload through SteamCMD when authenticated access is available
launch the Linux server through the shared steamcmd-linux Docker runtime

The remaining operator-provided prerequisites are:

authenticated Steam or SteamCMD access to Bannerlord dedicated server app 1863440 branch linux_test
a TaleWorlds custom server token before start

Anonymous SteamCMD is not enough for the supported Linux branch.

Quick Start

Create the server:

alphagsm mybannerlo create bannerlordserver

Configure SteamCMD credentials in your AlphaGSM user config so setup can use an entitled account:

[downloader.steamcmd]
username = YOUR_STEAM_USERNAME
password = YOUR_STEAM_PASSWORD

Run setup:

alphagsm mybannerlo setup

Generate a custom server token from the Bannerlord multiplayer client, then stage it where the dedicated server can use it, or pass it through the supported launch argument flow described in the official TaleWorlds hosting guide.

Start it:

alphagsm mybannerlo start

Check it:

alphagsm mybannerlo status

Stop it:

alphagsm mybannerlo stop

Requirements

Docker for the supported Linux runtime path
SteamCMD
authenticated Steam or SteamCMD access to Bannerlord dedicated server app 1863440 branch linux_test
a TaleWorlds custom server token generated from an owned Bannerlord multiplayer account

Setup Details

Setup configures:

the game port
the install directory
the Linux dedicated branch linux_test from Steam app 1863440
the Linux starter under bin/Linux64_Shipping_Server/

TaleWorlds Custom Server Token

Bannerlord dedicated hosting requires a custom server token tied to a Bannerlord account.

The official TaleWorlds flow is:

Launch Bannerlord multiplayer and log in.
Open the in-game console.
Run customserver.gettoken.
Copy the generated token to the host that will run the dedicated server, or pass it on launch with /dedicatedcustomserverauthtoken.

The token expires periodically, so replace it when TaleWorlds rotates it.

Useful Commands

alphagsm mybannerlo update
alphagsm mybannerlo backup

Notes

Module name: bannerlordserver
Steam App ID: 1863440
Steam branch: linux_test
Default port: 7210
Default executable: bin/Linux64_Shipping_Server/TaleWorlds.Starter.DotNetCore.Linux.dll

Server variables

After create bannerlordserver, 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

Run File

Executable: TaleWorlds.Starter.DotNetCore.Linux.dll
Location: <install_dir>/bin/Linux64_Shipping_Server/TaleWorlds.Starter.DotNetCore.Linux.dll
Engine: .NET Linux dedicated server started through dotnet
SteamCMD App ID: 1863440
Steam branch: linux_test

Runtime Notes

The supported Linux lane is the module's steamcmd-linux Docker runtime contract.
The validated setup blocker is no longer a missing dotnet runtime. The real gating requirement is access to the authenticated linux_test branch plus a valid custom server token.
