Yes, same here. Both are wired directly to a dumb switch using link local addresses. No router.

I tried 225.0.0.1 port 1234 on both ends.

I can't figure out what the contents of the buffer is. Just random bytes?

It is weird that the ifc number gets filled in after pinging the multicast address.

I tried the mcastsend and mcastrecv on my two raspberry Pi's running 9front.

How are you connecting these devices to the network? I use wired
connections to a single (dumb) switch.
