The dedicated server is distributed for Windows, so a Linux deployment runs the Windows files through Wine, most reliably inside Docker. The practical setup is a supported Linux host, Docker Engine with Compose v2, persistent storage for the server data, and correctly forwarded UDP ports.
Godlike.Host offers hosted Space Engineers servers with its own game panel, SFTP access and free DDoS protection, if you would rather not host it yourself.
What you are actually running on Linux
Space Engineers Dedicated Server is a Windows application. SteamDB lists dedicated-server App ID 298740 as Windows-supported and exposes both 32-bit and 64-bit Windows launch executables. Linux hosts therefore use a compatibility layer rather than a native Linux server program.
As an Amazon Associate I earn from qualifying purchases.
Wine supplies the Windows compatibility layer, while Docker isolates Wine, SteamCMD, the game files and the server process from the rest of the host. This arrangement is maintained by community projects, not by a native Linux build from Keen Software House. A game update, Wine update or changed dependency can therefore break an otherwise healthy installation.
The official distribution route remains important: obtain the files with the dedicated-server download supplied by Keen Software House or install App ID 298740 with SteamCMD. Do not copy or redistribute game files in a public image or download archive.

Choose the host before installing anything
Use a virtual machine, not an unverified container host
A current Linux Docker deployment documents Ubuntu 24.04, Wine 11, Wine Mono, SteamCMD and Docker Compose v2. If your provider offers both a virtual machine and an unprivileged system container, choose the virtual machine. The same guide recommends KVM and warns against LXC for this workload because Wine needs full virtualization support.
Other distributions can work, but package names, kernel defaults and Docker installation steps differ. Treat Ubuntu 24.04 as a known reference environment rather than a promise that every Ubuntu release or distribution will behave identically.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Plan a public network path
You need a host address that players can reach. On a home connection, this normally means a router with port-forwarding controls and a public IPv4 address. Carrier-grade NAT can prevent inbound connections even when your router rule is correct; in that case, use a hosting provider with a public address or a compatible tunnel after confirming that the game works through it.
Allow room for persistent data
Keep the server’s AppData, worlds, configuration, logs and downloaded mods outside the disposable container layer. A community layout uses a parent directory named space-engineers with separate docker, data and steam directories. The exact mount targets depend on the image or Compose project you select, but the principle is the same: replacing a container must not replace the world.
Install Docker and Compose v2
Install Docker Engine and the Docker Compose v2 plugin using the package source recommended for your Linux distribution. On Ubuntu, verify both components before downloading the game files:
docker --version
docker compose versionThe second command must return the v2 Compose plugin form, docker compose, rather than relying on the obsolete standalone docker-compose command. Add your administration account to the Docker group only if you understand that membership grants root-equivalent control over the host; otherwise run Docker commands with sudo.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsCreate a working directory and lock down its ownership before you add server data:
mkdir -p ~/space-engineers/{docker,data,steam}
cd ~/space-engineers
chmod 700 data steamDo not put the world in a temporary directory such as /tmp. Container recreation, host cleanup jobs or an image update can remove temporary files.
Obtain the dedicated-server files legally
Use the official archive
Keen Software House publishes instructions for obtaining the dedicated-server package. If you download DedicatedServer.zip, extract it into the persistent server-data location expected by your selected Docker project. Keep the original archive outside the live world directory so an update cannot overwrite the active installation accidentally.

Use SteamCMD
SteamCMD can install the dedicated server by its application ID. The relevant ID is 298740. A typical installation sequence is:

If SteamCMD reports that a file is locked or an update is incomplete, stop the server, remove only the failed download cache, then run the update again. Never delete the persistent world directory while troubleshooting an installation download.
Keep the SteamCMD files separate from save data. This lets you update executables without replacing worlds, configuration or logs.
Build or select a Wine/Docker deployment
Linux projects differ in important ways. Some build an image locally and patch DLLs to address mod-download problems; others publish a maintained Compose stack with automatic updates and optional plugin support. Read the project’s Dockerfile, volume declarations and update notes before exposing a server to the Internet.
Use a pinned image tag or commit when the project supports it. A moving latest tag can change Wine, SteamCMD or startup behavior without warning. A commit digest gives you a known-good rollback point:
docker compose pull
docker compose up -dRun those commands from the directory containing the project’s Compose file. If you build locally, use the project’s documented build command first and record the commit you used. Do not invent volume paths or environment-variable names: mount points and settings are image-specific, and a guessed path can make the container start with an empty world.
Your Compose service should have these characteristics:
- A persistent bind mount or Docker volume for the server’s AppData and saves.
- A separate persistent location for SteamCMD or downloaded game files when the project expects one.
- A restart policy so a host reboot does not leave the server offline.
- Explicit UDP publication for the game port and Steam networking port.
- An optional TCP publication only when you deliberately enable the remote API.
- Logs that remain available through
docker compose logsor a persistent log mount.
Configure the server settings
Space Engineers stores dedicated-server settings in SpaceEngineers-Dedicated.cfg. The graphical configuration tool supplied with the dedicated server, or the configuration mechanism provided by your image, should be used to edit it. The documented settings include:
- Listen IP: use
0.0.0.0when the server must listen on all container interfaces, which is the documented default in the wiki reference. Bind to a specific address only when you have a reason to restrict interfaces. - Server port: choose one UDP port for this instance. A single port can be used by only one server instance.
- Server name: the name players see in the browser.
- World name: the save that should load when the process starts.
- Steam Group ID: optional; use it when access should be associated with a Steam group.
- Password: optional; set one while testing or when the server is private.
The wiki also describes additional EOS network parameters. Change those only when you understand the network mode your build uses, and stay within the game’s tested ranges. An out-of-range value can prevent registration or produce failures that look like firewall problems.

Open and forward the correct ports
Port numbers are part of the server identity. The current Docker example uses the following mappings:
| Purpose | Protocol | Port in the example | When to expose it |
|---|---|---|---|
| Game traffic | UDP | 27016 | Required for that example’s player connections |
| Steam networking | UDP | 8766 | Required by that implementation |
| Remote API | TCP | 8080 | Only when the optional remote API is enabled |
Those are example values, not universal defaults. If you choose another game port, use the same number in the game configuration, Docker publication, Linux firewall and router rule.
Open the Linux firewall
For a server using the example ports, a host running UFW would use:
sudo ufw allow 27016/udp
sudo ufw allow 8766/udp
sudo ufw allow 8080/tcp # only if the remote API is enabled
sudo ufw statusKeep the firewall restrictive. Do not expose the remote API merely because the image documents it; leave TCP 8080 closed when you do not need remote administration.
Free tools Windows power users keep installed
One-click scans. No signup required.
Forward ports on a home router
Give the Linux host a stable private address, then create UDP forwarding rules for the configured game port and UDP 8766. Forward TCP 8080 only for an enabled and secured remote API. Test from another device on the same LAN before testing from outside. A successful LAN connection confirms that the world, process and local port are working; an external failure then points to forwarding, public addressing or the ISP.
Start the server and verify it in layers
- Start the service from the Compose directory with
docker compose up -d. - Follow startup output using
docker compose logs -f. Wait for the server to finish loading the selected world rather than testing while Wine is still creating its prefix. - Confirm that the configured world name appears in the log and that no port-bind error is reported.
- Join from a client on the same network. Check that the server name, password and world behave as configured.
- Test from an external network, such as a phone hotspot. This isolates router forwarding and public-address problems from game configuration problems.
- Stop and start the container once, then confirm that the same world and settings return. This is the simplest persistence test before inviting players.
If the process exits, collect the complete log before restarting repeatedly. Repeated restarts can hide the first error and make a failed update look intermittent.
Migrate an existing world
To move a world from a Windows game installation, copy it from the game’s save directory, AppDataRoamingSpaceEngineers, into the dedicated server’s persistent save location. The exact Linux path is determined by the container’s volume mapping, so identify that mapping before copying.
- Stop the dedicated server and make a backup of the destination data directory.
- Copy the complete world folder, including its files and subdirectories, into the persistent dedicated-server save location.
- Set the world name in the server configuration to match the copied save.
- Start the container and inspect the log for a successful world load.
- Join as an administrator first and verify inventories, scripts, mods and faction data before opening the server to everyone.
Do not migrate while the source world is still being written. Exit the game cleanly, or use a save copy made while the world is stopped, to avoid importing a partially written save.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Keep mods and data after container updates
Mods are a common source of confusion because the server executable, Wine prefix, Steam download cache and world files can live in different locations. Put the mod data and the world under persistent mounts defined by the project. If a container update starts with an empty Wine prefix or Steam directory, it may appear to have lost every mod even though the old files still exist on the host.

Some community images patch DLLs specifically to improve mod downloads. A change in that patch, Wine or the Steam client can alter mod behavior. After every image or game update:
- Back up the world and
SpaceEngineers-Dedicated.cfg. - Record the current image tag or commit.
- Update the image or Steam files while the server is stopped.
- Start the server with the previous configuration and watch the logs.
- Join privately and check that required mods load before announcing the update.
- Roll back to the pinned image and restore the backup if the world fails to load or mods disappear.
Automatic updates are convenient for a private test server but risky for a public world. Schedule updates during a maintenance window and keep at least one known-good image revision.
Run more than one instance
Every instance needs its own world, configuration, logs and host port. Assign a different UDP game port to each server and publish each mapping explicitly in Compose. If the implementation requires UDP 8766 for Steam networking, determine whether it supports a distinct Steam port per instance; never let two containers compete for the same host port.
Use separate directories such as data/server-1 and data/server-2. A shared mount can cause one container to load the other container’s world or overwrite configuration during startup. Give each instance a distinct server name so a client can identify the intended world.
Capacity, bandwidth and monitoring
Keen Software House’s retrieved networking guidance lists 5 Mbps bandwidth as a requirement or recommendation. The page does not state a publication year, so treat it as an undated official guideline rather than a modern performance benchmark.
The cited documentation does not provide a universal Linux/Wine CPU, RAM or player-count guarantee. Simulation load, world complexity, mods and concurrent players determine the real requirement. Start with conservative player access and measure the host under the busiest world activity you expect.
- Watch simulation speed and server tick behavior in the game.
- Monitor CPU saturation, especially when several players build or use scripts at once.
- Watch memory pressure and swap activity; sustained swapping usually indicates insufficient memory or an oversized workload.
- Measure disk latency when saving or loading a large world.
- Check container logs after crashes, mod updates and reconnect storms.
Bandwidth is only one part of the connection. A wired Cat6 Ethernet connection can remove Wi-Fi variability between a home server and router, but it is not a software requirement and cannot solve carrier-grade NAT or an undersized host.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Troubleshoot by symptom
The container starts, but no server appears
Check that the process completed world loading, the listen IP is not restricted to an unavailable address, and the configured port matches the published Docker port. Confirm that the Linux firewall allows UDP and that no second instance already occupies the port.
LAN players can join, but Internet players cannot
Verify the router forwards the same UDP game port configured in the server. Check the host’s public address and test from a genuinely external network. If the ISP uses carrier-grade NAT, ordinary forwarding will not create a reachable endpoint.

The server reports an address or port conflict
Only one process can use a given host port. Stop duplicate containers, list active Compose projects, and assign a unique game port to each instance. Update the router and firewall rules whenever the port changes.
The world resets after an update
The container is probably writing to its ephemeral layer or to a different mount than the one you backed up. Stop the service, inspect the Compose volume mapping, and confirm that the world directory contains recent timestamps. Restore the last backup before attempting another migration.
Mods are missing or fail to download
Check that the mod directory is persistent and that the container can reach Steam services. Review the image’s notes for DLL patches or required permissions. A Wine or Steam update can change mod behavior, so roll back to the previously pinned revision if the failure began immediately after an update.
The server crashes after a game or Wine update
Capture logs, record the new image and game versions, then return to the last known-good image or commit. Test the old world on the reverted stack before changing configuration. If the old stack works, the failure is compatibility-related rather than a damaged save.
Backups and recovery
Back up the world directory and SpaceEngineers-Dedicated.cfg before every game, Wine or image update. Keep at least one backup outside the host so a disk failure, mistaken volume deletion or compromised container cannot remove both the live copy and the backup.

Self-hosting versus managed hosting
| Decision area | Self-hosted Linux/Wine deployment | Managed game hosting |
|---|---|---|
| Control | Direct control of files, mods, plugins, worlds and configuration | Control depends on the provider’s panel and policies |
| Maintenance | You maintain Docker, Wine, Steam files, firewall, backups and updates | The provider handles much of the host and network maintenance |
| Public access | You provide the public address and port forwarding | The provider normally supplies the reachable endpoint |
| Cost predictability | Depends on your hardware, electricity, bandwidth and hosting plan | Usually a recurring service charge; verify current plan terms |
| Recovery | You control rollback images and off-host backups | Recovery options depend on the provider’s backup and export policy |
Keen Software House identifies GTX Gaming as its official PC server host. If you choose managed hosting, verify the current plan, data-center location, Linux implementation, mod support, backup policy and export process before moving a world. “Official host” does not by itself establish that a particular plan uses the same Wine/Docker arrangement described here.
Recommended operating routine
- Keep the Linux host patched, but schedule reboots rather than allowing an unexpected restart during a save.
- Use a pinned, known-good Docker image or commit.
- Back up the world and configuration before every update.
- Update Steam files and the container with the server stopped.
- Read the logs after startup and perform a private join test.
- Monitor simulation speed, CPU, memory and disk latency during peak activity.
- Expose only the required UDP ports and an optional secured TCP API.
- Document port assignments and volume paths for every instance.
The dependable Linux pattern is therefore a deliberately managed compatibility deployment: Windows dedicated-server files obtained through the official channel, Wine inside Docker, persistent host storage, explicit UDP forwarding and a rollback plan. It works well when treated like infrastructure rather than a one-time container launch.
