Extracting payload from ethernet dumps

[Simon Greifswald <edtfatr-ah () web de>]

Hello,

I have several gigabytes of dumped network traffic in files, and I need to 
extract the payload from each packet. So, I want to discard all link layer, 
internet layer, transport layer headers and only extract the udp packet's 
payload in a new file.

If it were not so much data, I used the wireshark gui's "Follow stream" 
function, but sadly this is not an option since there are too many files to 
parse. I would rather have a script do it for me. So what I need is a way 
using tshark, tcpdump or so to strip the headers from the packets.

Does anyone know a tool which can be used to do this?

Thanks in advance,

Simon
