Thanks for the prompt reply. I’ve read through exported_pdu.h and I don’t understand how this helps me. Is there somewhere I can
read more about using exported_pdu functions?
Thanks and regards…Paul
Have a look at ../epan/dissectors/packet-user_encap.c. It gives you ad idea on how to generate the right EXPORTED_PDU headers. Use it as packet headers, with an encapsulation of value 252 (i.e. using libwritecap calls) and you're done.
