Here's how to connect to your Kerbal Space Program (Multiplayer) server and adjust the most important settings.

Connecting

  1. Open the server page in the client area and click Start.
  2. Wait until the status shows “running”. You can follow the progress in the Console tab.
  3. Copy the address (IP:Port) at the top of the server page.
  4. Install the Luna Multiplayer mod (client) and add the address as a server there.

Important settings

In the Startup variables tab:

  • Mod Pack Mode (MODPACKMODE) – Specify the modpack type.
  • Warp Mode (WARPMODE) – Specify the warp type.
  • Game Mode (GAMEMODE) – Specify the game type.
  • Game Difficulty (DIFFICULTY) – Specify the gameplay difficulty of the server.
  • Server Name (SERVERNAME) – Name of the server.

Changes in the Startup variables tab take effect on the next restart.

Good to know

  • The first start takes longer because the server files are downloaded and set up.
