In Kerbal Space Program mods only run inside the game itself – the DarkMultiPlayer server does not load any KSP mods. Its job is a different one: through the file mod-control.txt it defines which mods players are allowed to use, and it can optionally distribute a ready-made modpack to them.
Generate and upload the mod list
You do not write the mod list by hand – you generate it in the game: the DMP client reads your GameData folder and writes the finished file from it.
-
Set up KSP with the mods you want
Install all mods that should be allowed on the server on your PC and start Kerbal Space Program. -
Open Mod Control
In the DMP window in the main menu click on Options and switch to the Advanced tab. It contains the Mod Control section. -
Generate the file
In the Mod Control section click on Whitelist or Blacklist. The file is written directly into your KSP folder:[KSP folder]/mod-control.txt -
Stop the server
Stop your server via the dashboard. The mod list is only read on server start. -
Connect via SFTP
Connect to your server via SFTP. -
Upload the file
Upload the file into the following directory and replace the existing one:/Config/mod-control.txt -
Start the server
Start your server. From now on it checks theGameDatafolder of every joining player against this list.
Structure of mod-control.txt
The file consists of sections, each starting with a !. Lines starting with # are comments.
| Section | Meaning |
|---|---|
!required-files |
Files every player must have installed |
!optional-files |
Files that may be installed but are not required |
!partslist |
All parts that may be used on the server |
!resource-whitelist |
Only the listed files are allowed (whitelist variant) |
!resource-blacklist |
The listed files are forbidden (blacklist variant) |
Entries are written as a path relative to the GameData folder, optionally followed by a checksum:
DarkMultiPlayer/Plugins/DarkMultiPlayer.dll=6a1c9a...
Configure mod control
How strictly your server checks is controlled by the value modControl in the file /Config/Settings.txt. Stop your server before editing the file.
| Value | Meaning |
|---|---|
ENABLED_STOP_INVALID_PART_SYNC |
Default. Vessels using forbidden parts are not synchronized to the other players. |
ENABLED_STOP_INVALID_PART_LAUNCH |
Vessels using forbidden parts cannot be launched at all. |
DISABLED |
No checks. Every player can use any mods. |
Distribute a modpack to your players
Optionally your server can provide the matching mods to your players so nobody has to collect them one by one.

Choose the mode
Open the dashboard, go to the settings and set the field Mod Pack Mode:Value Meaning NONEDefault. The server does not distribute any mods. CKANThe server sends a CKAN file containing the mod list to the players. GAMEDATAThe server sends the complete mod files to the players. -
Upload the modpack
Upload the mods via SFTP into the matching location:/Config/GameData/ (for GAMEDATA) /Config/DarkMultiPlayer.ckan (for CKAN) -
Refresh the file list
If you uploaded the files via SFTP, run the following command in the console of your dashboard afterwards:/reloadmods -
Inform your players
To install the pack, players need the additional tool DMP Modpack Updater from d-mp.org/downloads. Kerbal Space Program has to be closed for that – theGameDatafolder cannot be modified while the game is running.
