HI, I am new to vb.net and need help in sockets.

I need to create an application (console) which will act as a server. Then I will have clients that will connect to the server and send data to the server.

1) Client connects to server
2) Client sends data to server
3) Server processes data
4) Server send back data to specific client (as there will be more than on clinet at the same time)

My problem is how to establish a connection and how I can have 10 connections at the same time with the server communicating back to a specific client (probably using an ArrayList)
