Question

I have a python program that is supposed to connect to a server and receive specially formatted packets, that I can test and filter out. I can connect to the server, but I can’t see that I am receiving any packets – though I am sure that I am. I don’t know how to debug this.

class client:
    def __init__(self, host ='127.0.0.1', port=12345):    
        self.host = host    
        self.port = port    
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)    
        self.sock.connect((self.host, self.port))    

    def get_next_event(self):    
        pkt_size_data = self.sock.recv(4)    
        # on the above line I am not getting any response, the client just waits for something....    
        pkt_size = self.size_struct.unpack((pkt_size_data))[0]   #I never get here    
        pkt_data= self.sock.recv(pkt_size)    
#(  get_next_event is called from an infinite loop )    

I am using VS2010 – setting breakpoints – looking at my objects using VS2010 tools – are there some tools I can use to debug and see why I am not getting any response from the recv?

Any idea why I am not getting any response ?
