I would probably guess at a problem with the actual MAC address used by
that MicroVMS system, but it's pretty hard to troubleshoot this remotely.
But it's very clear that all the other nodes are not seeing 31.282 as
up, and so any communication will be failing.
Other possible problems could be if the connection to the outside
network is actually configured differently on this instance than the
others, for example.
Trying to think of other possible problems it could be. Maybe posting
the simh config for the failing machine, as well as for one working,
could be helpful.

But don't matter. Now we know they are all simh instances.

I thought SQE failure is only a warning and would
not stop the device
from working.

That's one possibility. Another if he's running on some kind of
emulator on a system that don't actually allow programmatic change of
the MAC address, and you need to set the MAC correctly in the
emulator before starting up. And if it is real hardware, is it
connected to some switch then?10baseT? Does he have an adapter that
can do SQE?
There are many possible ways things could not work. What we can see
isjust that incoming broadcast/multicast packets work, but so far
nothing else.

To unsubscribe send an email to hecnet-leave(a)lists.dfupdate.se Is it WiFi? That doesn't work with DECnet
MAC addresses (it doesn't
like it when the NIC changes its address to aa-00-04-00-xx-yy).
