For a long time, many people have been told to use the UDP punch Technology for Nat penetration, basically, no one will tell you how to use the TCP protocol to penetrate (or even some people will tell you that the TCP protocol cannot penetrate ).

After the standard UDP client has opened a set of interfaces, it generally uses the sendto and recvfrom functions to send data. Recently, we can see that the ntpclient Code uses the direct method of the send function, so we have analyzed it, in the
