title: wireshark: Capture Data Layer Only
body: <p>Is there a way to capture only the data layer and disregard the upper layers in wireshark? If not, is there a different packet dump utility that can do this? PREFERABLY 1 file per packet!</p>
  
  <p>What I am looking for: A utility that dumps only the data (the payload) layer to a file. </p>
  
  <p>This is programming related...! What I really want to do is to compare all of the datagrams in order to start to understand a third party encoding/protocol. Ideally, and what would be great, would be a hex compare utility that compares multiple files!</p>
