Hi,

I have three question:

1. What is easiest way to get my ethernet port IP address?

2. If i have a friend in another county and i want let him to control on my Arduino throw the Internet, What i have to do?

3. In line 4 the port is 3030 how to make it a universal port for my Arduino ?

var five = require("johnny-five");
var EtherPort = require("etherport");
var board = new five.Board({
port: new EtherPort(3030)
});

Thank you.

What is easiest way to get my ethernet port IP address?

In your terminal:

$ ifconfig

If i have a friend in another county and i want let him to control on my Arduino throw the Internet, What i have to do?

I suggest using a websocket to your node.js program.

In line 4 the port is 3030 how to make it a universal port for my Arduino ?

That comes from this line:

Thanks for your answers,

$ ifconfig ?? you mean $ ipconfig but i think this to get my computer ip address not ethernet port IP address!

In my node.js program, how etherport connect to my remote Arduino using only port (3030) and without Arduino IP address? i think i miss something!!

@tarek360 I meant ifconfig to get your computer's IP address. The instructions for getting the ethernet port IP are in this project's readme under Setup: steps 4-8
