Setting up a Satisfactory server on Linux | playit.gg

Setting Everything Up

Installing SteamCMD

For this to work, we will be using SteamCMD - here’s how to set it up. We will be using Ubuntu Server 26.04 for this guide. From your terminal, enter these commands - to install SteamCMD, the multiverse repository and x86 packages must be enabled.

Ubuntu

sudo add-apt-repository multiverse; sudo dpkg --add-architecture i386; sudo apt update
sudo apt install steamcmd

For other distributions, please refer to the instructions for your specific setup

Installing the Satisfactory Dedicated Server

You need a place to store the server - create a new directory, for example satisfactory

mkdir ~/satisfactory

Start installing the server from SteamCMD using this command:

/usr/games/steamcmd +force_install_dir ~/satisfactory +login anonymous +app_update 1690800 validate +quit

This will tell SteamCMD to start installing the Satisfactory server inside of ~/satisfactory.

If you get ERROR! Failed to install app '1690800' (Missing configuration), you should try adding +@sSteamCmdForcePlatformType linux to the command:

/usr/games/steamcmd +@sSteamCmdForcePlatformType linux +force_install_dir ~/satisfactory +login anonymous +app_update 1690800 validate +quit

Create the tunnel

Type: TCP/UDP
Port Count: 2
Local IP: 127.0.0.1
Port: NULL

We will match the tunnel’s local port to match the public one assigned by playit. Our public port is 62765, so we’ll set the local port to 62765. See Origin Configuration.

Satisfactory Tunnel Origin Configuration

Creating the startup file

In order to be able to join the server, you have to tell it which ports to bind.

Set -port to the public port of the tunnel, and -ReliablePort to the public port +1. Basically, the second port is one number higher than what’s shown on the website. For example, our public port is 62765, so our reliable port is 62766.

Create a new bash file, and set -port and -ReliablePort to match your tunnel’s information. We’ve called our file start.sh and placed it inside of the server’s root directory, where FactoryServer.sh is located.

nano start.sh

Save the file and exit the file by using CTRL + S, followed by CTRL + X

This is the command we will put inside of the file:

bash FactoryServer.sh -log -port=62765 -ReliablePort=62766

Starting the server

With our newly created script, we can run it by using bash start.sh

Claiming the server

When you create a new Satisfactory server, it creates a new unique identity using a self-signed certificate. Enter the tunnel information provided by playit like this:

You may get a warning, saying that the origin cannot be verified. It is safe to confirm this. If you are still unsure, make sure the identity matches the one printed in the console.

Server configuration

After you claim the server, you can then set an admin password. This can be done inside of the game, as a newly created server.

Set an admin password, and click Confirm

Choose whether or not you want to send crash logs to Coffee Stain. This is not required, this is up to you.

Creating a game

Once you’re here, you can configure the game as you see fit.

Here, you can set the server name, game rules, and other things.

Now you have a fully functional game server, running through playit.gg!

Troubleshooting

Refusing to run with the root privileges.

If you get this error, run the server without root, or using sudo.
