 Hello All,

 I used tcpdump to capture data on my network. I would like to analyze
 the data using python -- currently using ethereal and wireshark.

 I would like to get certain type of packets (I can get the hex code
 for them), what is the best way to do this? Lets say I want to capture
 all events of `ping localhost`

 TIA

You need python module pypcap or pcapy to capture the packet, and
the you can use Python to analyze it.
To decode the internet packet you can use dpkt.

Good Luck!

The following is pretty straightforward.

def process(dump, wanted, func):
  for packet in dump:
if packet_type(packet) == wanted:
  func(packet)

Perhaps you can ask a more specific question.
