Kerbal Space Program Server Setup Guide


Kerbal Space Program supports multiplayer through community mods: Dark Multiplayer (DMP) and Luna Multiplayer (LMP). This guide covers setting up both server variants on Legion Hosting, including configuration, startup variables, and connecting players.

Before You Begin: Make sure you have access to your GPanel account. If you need help locating your server details, see How to Find Your Server IP and Port.

Which Multiplayer Mod?

Your server will be set up with either DMP or LMP depending on the egg selected during provisioning:

Mod Full Name Runtime Notes
DMP Dark Multiplayer Mono Established mod with various warp and mod sync modes
LMP Luna Multiplayer .NET 5 Newer mod with admin password support and XML configuration

First Start

  1. Log in to GPanel and select your KSP server.
  2. Navigate to the Console tab. The server will download the required files automatically.
  3. Wait for installation to complete. DMP downloads from d-mp.org; LMP downloads from GitHub.
  4. Once ready, look for Ready! (DMP) or All systems up and running (LMP) in the console.

DMP Startup Variables

If your server uses Dark Multiplayer, these variables are available in the Startup tab:

Variable Description Default Options
SERVERNAME Server name displayed in the browser DMP Server Any string (max 48 chars)
GAMEMODE KSP game mode SANDBOX SANDBOX, CAREER, SCIENCE
DIFFICULTY Game difficulty level NORMAL EASY, NORMAL, MODERATE, HARD, CUSTOM
WARPMODE How time warp is handled in multiplayer SUBSPACE MCW_FORCE, MCW_VOTE, MCW_LOWEST, SUBSPACE_SIMPLE, SUBSPACE, NONE
MODPACKMODE How mods are synced between players NONE NONE, CKAN, GAMEDATA

DMP Configuration File

The DMP config file is located at Config/Settings.txt. It uses a properties format (key = value). GPanel automatically sets port, game mode, difficulty, warp mode, whitelist, and server name from your startup variables.

LMP Startup Variables

If your server uses Luna Multiplayer, these variables are available:

Variable Description Default Options
SERVER_NAME Server name (max 30 chars) Pterodactyl Any string
PASSWORD Server password (leave empty for public) Empty Any string (max 30 chars)
ADMIN_PASSWORD Admin password for in-game server management Empty Any string (max 30 chars)
MaxPlayers Maximum number of concurrent players 20 Any number
GameDifficulty Game difficulty level Easy Easy, Normal, Moderate, Hard, Custom
GameMode KSP game mode Sandbox Sandbox, Career, Science
LMP_VERSION LMP version to install (leave blank for latest) Latest e.g., 0.29.3

LMP Configuration Files

LMP uses XML configuration files in the LMPServer/Config/ directory:

  • ConnectionSettings.xml -- Port and network settings
  • GeneralSettings.xml -- Server name, password, admin password, max players, game mode, difficulty
  • GameplaySettings.xml -- Detailed gameplay parameters
Difficulty Note (LMP): Changing the GameDifficulty variable may produce a mismatch warning with GameplaySettings.xml. If this happens, delete GameplaySettings.xml so it regenerates with the correct difficulty presets, then restart.

How to Connect

  1. Install the matching multiplayer mod (DMP or LMP) in your KSP game client. Follow the mod's installation instructions.
  2. Launch Kerbal Space Program.
  3. Open the multiplayer mod's menu from the main screen or space center.
  4. Add your server using the IP and port from GPanel.
  5. Click Connect. Enter the password if one is set.
Finding Your IP: Your server IP and port are displayed on the main page of your server in GPanel. Ports are randomly assigned unless you have a private IP. For detailed instructions, see How to Find Your Server IP and Port.
Mod Matching: All players connecting to the server must use the same multiplayer mod (DMP or LMP) and ideally the same KSP version. Mismatched versions will cause connection failures.
