Enabling RCON on your Factorio server

To enable RCON for your Factorio server, you need to contact support using the chat bubble on the bottom right of the page and let us know which server you want RCON enabled on and what you want the password to be. We will enable it for you and give you the port number required to connect.

That's it! RCON is now enabled and ready to use. To learn how to connect with RCON, see this article. The full list of Factorio commands can be intimidating because there are so many different commands! You can also use tools like Factorio wiki's command list to find the commands you need. And as always, if you need any help, contact us with the chat bubble on the bottom right of the page.
