title: Windows 7: sniff TCP sockets to localhost
body: <p>I want to capture and analyze TCP communication data between two applications running on local host, which is running Windows 7 OS.  I try to use Wireshark, but Wireshark could not capture the data, it seems just monitor the data in/out the network interface. </p>
  
  <p>Could you introduce some useful tools to monitor the local TCP data easily.</p>
