0 9.1023 Tunnel52 0000.0000.0000 A
I have compared our tunnel configs and they are both the same, so I'm
guessing it is a Cory's end.
Cory, let me know if you want some help fixing this, although it seems your
up to your eyeballs in it with your 11/23+.
The issue isn't tunnels, exactly. It's the fact that I currently can't
contact Cory's router via SNMP to push the new config to. This doesn't
affect people like you who's tunnel config is still correct but does
affect someone like me who's IP has changed so Cory's router can no
longer talk to me. And I can't update it because his router refuses to
talk to me. :)
Oh, SNMP push works. TFTP doesn't.

Essentially, the MAC address in the actual ethernet controller (or the
MAC address set before boot in simh) is irrelevant. Once DECnet starts
running, that MAC address is not used anymore. It is just a trivia piece
of information so that you can know what the hardware MAC address from
the factory is. It is not used by anything, especially not anything
related to network communication.
The only reason I might find the actual hard-coded MAC address to be
useful is in identifying machines. A lot of Ethernet cabinet kits have
stickers on them with the MAC address printed on them.
Of course nearly every one I've seen has been WRONG, but.. ;)

Get an M+ system with split I/D space, and use my TCP/IP instead... :-)
If all goes well whenever Dave heads out this way he'll be dropping off
some -11s that HOPEFULLY have split I&D.
I peeked into the side vents of one of them; it has a J11 of some
sort, so you should be good there!

This is on the node running NFT, not FAL.
The plot narrows.
For completeness (feeding Google) : 2 11M+ DECnet nodes running inside
simh inside a same instance of a VirtualBox Linux machine.
More interesting would be to see EXEC COUNTERS, as well as counters for the two nodes, from both sides.

I had some issues about a week ago where it seemed your end was going yo-yo all the time, so I disabled it to test things. Forgot to turn it back on. Fixed now.

Sounds like a good idea. Probably takes less time to do than what I suggested.

I have another idea waiting in the queue : virtualize a second NIC
and have each node have it's own. Bridge the virtual NIC's with real
ones, so they communicate over wire.

Of course, silly me. I forgot your IP had changed recently.
