Hi, I would think that it is cause it is listening and therefore it wont
know the foreign address source port, thats why it is set to zero, it will
accept any src port coming into that listening port.

Guys / Gals Do you know what means port zero in Windoze Platform ? I know
the answer but jst wanted to know anyone has a better explaination.

In Unix Family port zero is used for socket programming but not the same in
Windoze family.

I have asked this question in many programs of mine in CEH - Certfied
Ethical Hacking but still awaiting for answers. Lemme see if can get some
answers for this post!!!!
