Re: SocketCAN over Ethernet

["Max S." <max@schneidersoft.net>]

Hello,

I don't know of a direct way of hooking up two socket can interfaces
over eth.

If this is just a quick fix or development crutch and not for production
you could try the following: Create a VCAN interface on both machines.
Create a simple userspace program (perhaps in C) to listen to the VCAN
interface, and transmit the frames read, via UDP (or TCP), to the other
machine. Create another program to listen to the UDP traffic and dumps
it into the VCAN interface on the other host. invert the roles and
you've got duplex.

If the arch of the two hosts is binary compatible you don't even need to
encode data.

I have done this while I was working on a display software, It allowed
me to work on the laptop on the sofa using live can data aggregated by
sensors and a server elsewhere.

Regards,
Maximilian Schneider.
