DeviceNet dissector

[Hans-Jörgen Gunnarsson <Hag () hms se>]

Hello!

We are trying to develop a dissector for DeviceNet. We want it to work in Windows and have made some progress. We have 
constructed software that takes DeviceNet messages from the CAN-network through an IXXAT USB-to-CAN-dongle and 
transforms them to Ethernet where it can be picked up by Wireshark. Every message gets a special OUI that the dissector 
uses to pick them up.

For wireshark we have constructed a plugin that picks up the messages and partly decodes them. The problem is that it 
might be better to pick the DeviceNet-messages directly from the dongle into Wireshark. Perhaps through SocketCAN or 
something like that. That way we could pick it up, send it to the DeviceNet dissector, dissect what can be dissected 
and then add bodytype information and send it through to the CIP dissector.

We haven't found a good way to do this though. Do you have any ideas or thoughts?

Thanks

Hans-Jörgen Gunnarsson
