The files are script files, and by default they open in TextEdit. To change this, you just need to change what the default program for it is.

Open the "Get Info" dialog for the file, and under the "Open With..." section, there should be an "Other" option. In the menu that appears, choose Terminal to be the new default application.

It should run now. Have fun!

Well, if you are not using LAN than you need to port forward your IP. It is different depending on your router but I would suggest looking up a port forwarding tutorial. You just need to make sure that you use the correct IP when doing this. Once you have port forwarded you should be able to give your friends your public IP address. To figure this out just type in "my ip" in Google. Your friends should be able to connect once you do this.
