Scapy has a
sniff function that is great for getting packets off the wire, but I recently discovered just how great this feature really is. There’s an argument to pass a function that executes with each packet sniffed. The intended purpose of this function is to control how the packet prints out in the console, allowing you to replace the default .
nsummary display with a format of your choice.
In the ScapyDoc.pdf, the
prn argument is defined as:
prn: function to apply to each packet. If something is returned, it is displayed. For instance you can use prn = lambda x: x.summary().
