Hi,
We have some interns that have written a dissector for CAN
and is also have the possibility do dissect protocols running on CAN. To capture
the CAN packets special hardware is required, for now they have a simple app
that reads the CAN packets and encapsulates them into an Ethernet frame and
passes it on to a NIC.
Today the CAN data is encapsulated as a in the 802.3 frames
using the SNAP header on an unregistered oui. This is a similar to how BACnet
MS/TP frames are captured on RS-485 and passes them on to Wireshark.
Is this CAN dissector that you could consider adding to
Wireshark? If yes what would be the preferable way to encapsulate the CAN frames
to have them passed on to Wireshark?
Thanks,
Joakim
