The DIX spec says that hardware addresses ( the ones you put in the simh configuration file starting with 08-00-2B) must be unique .
Yes. But that is because no two controllers should have the same MAC address, because it would break communication on the ethernet. But what this really is about is the MAC address used during communication. And since the address is changed by DECnet, it that that address that needs to be unique from a technical point of view.
And it only actually needs to be unique within the same ethernet segment.

I tried and it maked no change.
Right. Since your machine will set a different MAC address anyway,
at start, when you enable DECnet. The physical address is whatever
you set in simh before starting. It have no actual relevance once
DECnet starts. If you were to run something else, which did not use
DECnet (such as Unix), the address you set in simh will be the
actual MAC address used, since IP do not change the MAC address of
interfaces. No need.
You mean "the Hardware address is whatever you set in simh before
starting". CEX will set it to "Physical address" (in DECNET parlance)
which is AA-00-04-00-(1024 x area + node).
The MAC address is AA-00-04-00-01-28 for DECNET and 08-00-2B-AA-BB-CC
for Linux.
So, a NIC may have different MAC addresses depending of the network
stack running. Am I right here?
Really hard to give a good explanation on why without having good
access to all parts of the setup to be able to test and examine
things.
Well, my system is working 99%, that's not so bad :)

Hello!
Are you sure you don't have the entire Monty Python crowd working
inside your setup Brian? Sorry I couldn't resist.

I didn't know that existed until just now! :)
Now you do!
Which simulator?
PDP-11 mainly.
Which OS? I seem to have had issues getting it to idle lately...but let's
just say I do some crazy things.
After the move I'll be able to power on the Xserve, which means SIMH,
but I'll also be able to power on some actual VAX hardware, so I'll run
VMS on those. :)
Get a real -11, too! ;)

Just checking the vax780 simulator now, it's running VMS 7.3 and eating a 4.5& of the CPU of my MacBook pro.
So I guess it does.
That's good news, thanks! :)

Hi,
So now I'm connected via GRE tunnels, and assigned a decnet cost
to the local ethernet interface on my router, but I'm not quite
working yet.
1) I ran SYS$MANAGER:NET$CONFIGURE.COM, but something isn't quite right.
2) Once I get DECnet configured and working, what can I connect to?
Uh, it seems you are installing DECNET Phase V, also known as DECNet-OSI. Unless you are doing this for the sake of it, I'd suggest to uninstall DECNET-V and go back to DECNET Phase IV, which is far easier to set up.
Having said that, that OPCOM message is telling you that you have not configured any DTSS (Dec Time Server) in your LAN. At least one of your nodes should be configured as DTSS server (you must install de DTSS software answering yes to one of the questions you get installing the kit, and after that, configure the server itself).
If you succeed you can test DECNET over IP transport doing a SET HOST to jguillaumes.dyndns.org; you should get into BITXOZ, which is my own DECNET-V node. BITXOZ is also a DDns server, providing name info for the HECNET: namespace. As far as I know, there is no HECNET-wide standard for implementing Phase V, so I rolled my own server :)

I know this is real beginner stuff, but in spite of tons of
documentation about OpenVMS and DECnet, I'm not sure where to
go with this.

Hi,
I'm thinking I'd like to get connected to hecnet, and maybe put one
of my VAX systems online.
I've got a static Verizon FIOS IP, and a Cisco router with which I could set
up a GRE tunnel.
Who can help me?
