Wireshark Dissector for MQTT

[Dave C-J]

Are there any thoughts on adding a Wireshark MQTT Dissector to the Eclipse project ? Something like 

http://false.ekta.is/2011/06/mqtt-dissector-decoder-for-wireshark/

but capable of working with the new connect headers etc ?

Why not try and get support into the core of Wireshark? Would love to see tcpdump support too.

Getting it into core wireshark will be a complete rewrite, just fyi. :)

The gross hacks and outdated plugin style that I built that with _work_ but only just, and not
in any way that would ever be accepted back upstream. Would be nice though, agree there :)

Sometime ago we did a lua plugin for this purpose. I have been thinking about adapting it to the New specs. And specialy mqttsn. If there is some interest in the group we can retake it.

That's the link and as you can see is kind of abandoned for a big while.

Hello everybody,
I am in the process of writing a Wireshark plugin to disect 3.1.1 messages.
If there is any interest once I have the basic framework written and can decode some of the basic messages I can provide the plugin for some testing.
In the long run I am planning on supporting 3.1 and 3.0 messages and I am going to try to get it included in the mainline releases ... but one thing at a time.

That's a nice idea. I was trying to use the Websocket dissector to monitor some MQTT traffic and it would have been nice to have a MQTT specific one to go along with monitoring websockets.

+1, great idea, would love to see MQTT in the wireshark release...I would also test the plugin, if you have the basic framework ready...

[Dave Locke]

+1 from me

To generate test data you might like to try the OASIS MQTT 3.1.1 conformance test suite that is being put together in the Eclipse Paho project. It contains a python MQTT test client and server that will create MQTT packets on the wire that conform to the OASIS spec. Details can be found here: https://wiki.eclipse.org/Interop_Testing_Plan    


All the best
Dave
