Hi, I have coded (and learned) the BeatBox with (chat) program from Head First Java. If I want to give the beat box program to my friends in other locations, should I change the IP address and the send the code to them. or can i just send the code which I am using.

I feel we cant use 127.0.0.1 IP address to send it to others.. Please clarify.

thanks

127.0.0.1 is the loopback address. From any machine, you can get to the same machine using that address.

I have one more basic question!? Do my friends whom I send the Beatbox code should run the music server tooo? or is it just me who will run the music server?

thanks

If your friends will be using 127.0.0.1 as the connection address, then your friend's server can only connect to your friend's server. They won't be connecting to your server. They won't be connecting to each others server. The client can only connect to the same server as the client.

That's why the address is a loopback address.

You need to ask your friend's WAN IP address and use that IP address in your beatbox program to connect to your friend. Your friend should have the client for the beatbox.
