FOSS gamedev and creative worlds

Hi everyone,
I have several offline computers which I connect with an ethernet switch or by a direct ethernet cable connection. Some are running Windows and some are running Ubuntu. How do I connect them all for a multiplayer game?
Thanks in advance.

You start a lan game on port 30011 by default, open port 30011 on your network alone and others on your network can play.

Thanks! What do I set the IP to and will I be able to save games?

1. idk, 2. yes

You can find your internal IP by opening a command line.

On Windows, press Windows+R then type in "cmd" without quotes, then type this:
ipconfig

On Ubuntu, open a Terminal (search "Terminal" in the Dash if you're using Unity) then type this:
ifconfig

Thanks guys, it worked great!
