Hello Pascal, I don't find any .c files under (ubuntu) /usr/share/wireshark - is this only available to a dissector that's linked-in to the executable? Or can I access it via lua, as well? Or, do I only need to get the source tarball in order to study the example? Would it be wiser to ditch my lua code and do it in c? TIA cts On Wed, Oct 15, 2014 at 9:13 AM, Charles Smith <cts.private.yahoo () gmail com> wrote:

Or do I have to fetch it from somewhere?Yes it's a built-in dissector. Please have a look at packet-catapult-dct2000.c for an example on how to call a sub dissector via call_dissector_only() function (it is easier than using the UDP framing protocol which is more suitable when calling Wireshark from an external program).On Tue, Oct 14, 2014 at 7:22 PM, Pascal Quantin < pascal.quantin () gmail com> wrote:2014-10-14 17:33 GMT+02:00 Charles Smith <cts.private.yahoo () gmail com>:Hi. I have created a dissector for our tunnel protocol. I have the feeling that if I want to decode a payload protocol, say LTE MAC protocol, I'd use the proto() statement to hang that into my tree and some library code somewhere would do the rest of the decoding ... but I can't find these libraries (e.g. http://wiki.wireshark.org/MAC-LTE). Can someone set me straight? ctsHi Charles, LTE MAC dissector is a bit specific as it requires some meta data allowing it to know how to decaode the payload. You have 2 ways to configure it: - either look at epan/dissectors/packet-catapult-dct2000.c and check how it is configuring those meta data (mac_lte_info structure attached to each frame) - or use the UDP framing format as described in epan/dissectors/packet-mac-lte.h file. Some sample code demonstrating how to use it can be found here: http://wiki.wireshark.org/MAC-LTE Regards, Pascal. ___________________________________________________________________________ Sent via: Wireshark-users mailing list < wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark orgArchives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe
