Starting the server

Running server on Linux​

Prerequisites:

  • Git
  • Node.js

Go to the directory where you want to create your server and run the following commands:

git clone https://github.com/Space-Eternity-3/SE3-Server.git
cd SE3-Server
npm i
npm start

Joining to your server​

When you start your server, it will be visible for computers in your local network (LAN) on port 27683. You can type in the SE3 address field ws://local.ip:27683 or ws://local.ip:, where local.ip is your local IP address, for example 192.168.0.10.

To join to your server from internet, you need to forward port 27683 on your router. Read more on portforward.com. Then you need to check your public IP address on whatismyip.com. When you forward a port, everyone can join to your server using address ws://public.ip:27683 or ws://public.ip:, where public.ip is your public IP address.

If you can't for some reason forward ports, you can use page playit.gg to tunell TCP traffic through the external server with ports already forwarded. Note, that this way you will increase your server's ping.
