How to Become Server Owner on Your Astroneer Dedicated Server

The server owner has admin control: kick players, ban players, enable whitelist mode, save the world, and shut down the server from the in-game menu.

Setting Yourself as Owner (Before First Join)

This is the official recommended method from System Era:

1. Stop your server
2. In the XGamingServer Panel, click Files
3. Open Astro/Saved/Config/LinuxServer/AstroServerSettings.ini
4. Set these values:

OwnerName=YourExactSteamName
OwnerGuid=0

5. Save and start your server
6. Connect with the Steam account matching OwnerName
7. You are now the owner — a unique GUID is automatically assigned to your account

📝 Note: The OwnerName must exactly match your current Steam display name. After connecting, the OwnerGuid is automatically updated to your SteamID64.

Alternative: Pre-Set with SteamID64

If you know your SteamID64 (find it at steamid.io):

OwnerName=YourName
OwnerGuid=76561198012345678

This assigns ownership immediately without needing to match the Steam name.

Alternative: First Player Becomes Owner

If both OwnerName and OwnerGuid are blank, the first player to connect becomes the owner automatically.

What the Owner Can Do

In-game, the owner has access to an admin panel with:

• Kick — remove a player from the session
• Ban — permanently block a player
• Whitelist — enable DenyUnlistedPlayers=True to restrict access
• Save — trigger an immediate world save
• Shutdown — gracefully shut down the server

Enabling Whitelist Mode

In AstroServerSettings.ini:

DenyUnlistedPlayers=True

When enabled, only players on the approved list can join. The owner manages this list through the in-game admin panel.

Transferring Ownership

1. Stop the server
2. Change OwnerName and OwnerGuid to the new owner's details
3. Save and restart
