   Think of it in terms of duplicate fds which refer to the same socket,   
   rather than duplicate sockets. There is only one TCP state, only one   
   set of TX/RX buffers and so on. (Same as with disk files.)   
      
   So I think what you want cannot work.  If you have control over the   
   server, why do you need to snoop it, anyway?  (Short of debugging it   
   using tcpdump, that is).
