Automating extraction of UDP payload from pcap file

0

Hey,

Was wondering if it's possible to point Wireshark, or a Wireshark utility, at an existing pcap UDP capture file and have it do the equivalent of: * Follow UDP Stream * Save As (Raw format) to a specified output file ...from the command line.

Is this doable?

Thanks!

Please read the scripting part of my answer to a similar question.

As an alternative, you can run tshark with the options -V and -x, or -T dpml and then and extract whatever you need from that output.

tshark -nr input.pcap -V -x | your_script
tshark -nr input.pcap -T pdml | your_script

Regards

Hey Kurt,

Using '-T pdml' + a little bit of post-processing on the data.data element - works like a charm.

Thanks!
