Hi Florian, see information below. Martin On Tue, Jan 17, 2012 at 5:51 AM, Lehmann, Florian (EXT-Other - DE/Ulm) < florian.lehmann.ext () nsn com> wrote:
Hi All, I hope this is the right place to ask as I can't find any helpful information. I have a simple UDP Protocol, which has a MAC-LTE packet embedded. After dissecting my part of the packet, I would like to call the MAC-LTE dissector on the rest of the data.
Did you see the existing heuristic dissector? Is this format suitable for what you are doing? See the MAC-LTE wiki page and the link to packet-mac-lte.h for details. I also have a change almost ready to submit that breaks the parsing of the context information out from the heuristic dissector into a separate function (I have a need to write to a file with a new DLT, where the format of the frames is just the context header followed by the MAC payload. So I have a simple dissector that will register with a DLT (or use a "user" one, parse this header and pass the payload to the "mac-lte" dissector).
Calling the MAC-LTE dissector like: local dissector = Dissector.get("mac-lte") dissector:call(buffer(macPduDumpDataPos):tvb(), pinfo, subtree) results in the following error message: Can't dissect LTE MAC frame because no per-frame info was attached. Could anyone point me in the right direction, how to dissect only the header information from my custom protocol and to call the MAC-LTE dissector afterwards? I am using Wireshark version 1.5.1-RL30_110407 (SVN Rev 35697 from /trunk).
