Receive packet using socket

[tspiegelman at amplify.com]

BTW what I am trying to accomplish is easily done in hping3 using this command:
hping3 mtalk.google.com -S -p 5228 

I just want those same kind of results using python so I can make an exe out of it.

I am having some problems with the recv functionality of socket.  Below is the script I am using.  I get an ack from the server (used wireshark to ensure it was working) when I run this, but the script doesn't see the ack for some reason and the script exits with this error or a timeout:
