[How do i] Setup a simple server or so

Ok i managed it to get the server running, and emitting data through.

And making an Automatch system for 2 players.

but now i have a problem, everytime im emitting a string form my text box through, then i get it back the first time right.

Second time x 2

3rd time x3

4th time x 4...

I have no idea why. Heres a part from my server code in case something is wrong with that:

socket.on("message", function(data){

          socket.on("chatmessage", function(data2){

               io.sockets.in(data).send("chatmessage," + data2);

          });

          socket.on("GameSettings", function(data2){

               io.sockets.in(data).send("GameSettings," + data2);

          });

     });

I know the post is old, but better keeping this alive then always making a new thread for almost the same topic...
