How can you have a TCP connection back to the same port?

This may be caused by TCP simultaneous connect (mentioned on this post to LKML see also here ).

A TCP connection is uniquely identified by this tuple (local address, local port #, foreign address, foreign port #). There is no requirement that local address and foreign address, or even that the port numbers be different (though that would be exceedingly strange). But there is at most 1 TCP connection that has the same values for a given tuple.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
