IP Address of PCs connected to my machine

[crash.test.dummy]

Hi,
I have a Swing application (running on PC1) that listens on a
specific port, but its not tied up to a particular machine, so any
machine "can connect" to PC1. It is like a chatroom application that
anyone can join in and send and receive messages (except that I'm not
running on the web).

With this, how do I know the IP addresses (LAN/WAN/frame relay) of
the machines connected to PC1?

Thanks for your help.

Ask the sockets corresponding to each connection you've accepted().
Socket.getInetAddress() is what you are looking for.

I'll try this one. Thanks a lot!

How about:

InetAddress a = InetAddress.getByName( "some_url_arg" );

How about:

InetAddress a = InetAddress.getByName( "some_url_arg" );

That would seem to assume that you already know who is connected,
which I believe was the original question.
