Setting up a StarRupture Dedicated Server (Experimental feature) using the Steam App

Step 1 - Installing server files

Steam App: In the Steam App, go to your Steam Library and set the search filter for both ‘Games’ and ‘Tools’. After setting the correct filter, find ‘StarRupture Dedicated Server’ and install the tool.

Step 2 - Finding and launching the server

Important note: Steam account limitations

  • You cannot run the server tool and the game at the same time on two different PCs using the same Steam account if the server is launched from the Steam client — Steam allows only one active session per account.
  • It works if:
    • The server is launched on the same PC as the game,
    • The server is launched on a different Steam account,
    • Or the server is launched without the Steam client (using the BAT file), because it does not start a Steam session.

Use the .bat method below if you want to change the server port or avoid launching the server through the Steam client:

After Installation is completed, right-click the StarRupture Dedicated Server name, select ‘Manage’ and then ‘Browse local files’.

Inside the folder, right-click SRServerWithLog.bat and choose Edit.

In the first line, paste:

start .\StarRuptureServerEOS.exe -Log -port=7777

The command-line arguments enable you to log and choose which network port the server will use.

The port number you set here (e.g., 7777) must correspond to the same port that you have opened and forwarded (see Step 3) in your router/firewall so that players can connect.

Save the changes and close the edit window.

You can now launch the dedicated server directly by running SRServerWithLog.bat.

This short .bat method is useful when you want to change the server port or run the server without Steam.

After each update, you may need to edit the SRServerWithLog.bat because the command-line arguments may reset.

SteamCMD:

Another way to install a dedicated server is to use SteamCMD. Here you can find the documentation on how to install SteamCMD on various platforms. For your own convenience, you should extract the package close to the root folder (C:\ on Windows). Run ‘steamcmd.exe’ and it will install the newest version of the tool.

Windows:

Let's assume that your folder for SteamCMD is C:\SteamCMD\ and the destination folder for server files is C:\StarRuptureDS\

Open a Windows Command Prompt (cmd.exe):

C:\SteamCMD\steamcmd.exe +force_install_dir c:\StarRuptureDS\ +login your_steam_login +app_update 3809400 validate +quit

You may be prompted to provide a password or a Steam Guard Code. You will also need to update your SRServerWithLog.bat. Start the server by clicking SRServerWithLog.bat.

When the server is running, the player can manage it from within the game.

A known issue: after starting a server by loading a previously saved session, the player does not receive a pop-up window informing that the server was launched correctly.

Step 3 - Setting port forwarding

If your server is behind a router, you need to forward incoming connections from the external IP to the server’s internal IP and the port specified in the previous step (i.e. 7777). For more information and instructions specific to your router, visit https://portforward.com/.

Step 4 - Finding your own External IP

To find the IP address needed to connect to your server (together with the port), you can use any “what’s my IP” website — for example: https://www.whatsmyip.org/
