The socket operations you're calling on the client side are blocking (don't return until some data is received or a timeout occurs) which makes it hard to listen for messages sent from the host and let the client instances enqueue data to send at the same time. asyncore is supposed to abstract the .... Initially setup our socket: server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) Next, we can set the following to overcome the "Address already in use" that we hit often while building our programs: server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) This modifies the socket to allow us to reuse the address.
