Hi,

I have been tracing dnp3 packets through Wireshark and whenever a Group0 Var 204, 205 is received the packet it not completely parsed due to the unknown object error. Is there a list of what the dnp3 filter supports or to which specification the filter is complaint with ?

There is no external list, but the following is extracted from the current dissector (master branch) showing the Group 0 variations that are handled:

Hi,

Thanks for your reply. I do not have access to the specification but I know that for variation 204, 205 the data type is short floating point. I will still raise an enhancement request and if time permits would try and implement it myself

I've found information about the new g0 variations 196-210 and I'm in the process of adding them to the DNP3 dissector, but SharkFest EU is taking up a lot of my time at the moment, so maybe next week.

Sounds good. Ill be waiting for an update then!

Can you share the capture with the unsupported variations, I would like to test the code I've added?

Sure! Here it is! Group0 Capture
