We established that, yes. That's where my idea of using pcap and

Why promiscuous? So long as you can get the DECnet style individual address delivered,
and the multicast addresses that DECnet would register, I don't see a need for
promiscuous mode.
Right. There is only need for promiscous mode if you sit on an interface with the
"wrong" MAC address.
However, if you want to have your DECnet stack portable, you will need to go down that
path, as some Unixes don't have a way to change the MAC address of an interface at
all.
Also, to comment on your previous post, Paul.
Correct, the API of the current Linux DECnet is not possible to adopt to a new user-level
DECnet implementation, as they use explicit system calls, and you can't siphon those
off.
Had it all been done through a decnet library, it would have been easier. But the current
Linux solution is (I think) similar to the Ultrix one. And it do make sense from a pure
interface point of view.
