Even though I think I know the answer to this question, I'll ask it any way...
Is it OK to run machines that are in the same area on different subnets? For example, passing traffic between SLAVE:: and RIPLEY:: both on DECnet area 4 but on different subnets connected via a bridge?
I think it is and that the bridge is transparent, but for some reason in the back of my mind I have the concept of 'area router' and that doesn't fit with this model.
Thanks, Mark.

There has been very little success with IDE to SCSI converters on this age of machine.
Remember also that even 4000/90 vintage VAXstations generally have an upper limit of 18GB.
I don't recall anyone even getting an IDE drive to work, let alone an SSD.
Would love to be proved wrong however! I'm surprised someone hasn't written a software based SCSI drive emulator the same way that you get floppy emulators.
Consider running the machine diskless, booted off the network with off-node disks.

NU2.COM gets around that, and other issues.

Yes, that is why NU2.COM uses nodename.dat.

I assume that is because you have nodename information locally that is
not known at MIM, in which case yes, you might get burned.
I try to register all my node name/number allocations with BQT, seems
like the sensible thing to do, have them in a central database
somewhere.

NU2.COM parses NETNODES.DAT for you already. That is how it works. You always have the latest DECnet database to work with.

Should give the same errors, assuming SGC has an up to date nodename
database.
The problem is when node names gets moved to new addresses. Old
information is not cleared out by an NCP COPY command, so you might get
duplicate information in that case.
There is a MIM::US:[DECNET]FIX.COM which will do the right thing on a
VMS system for you. And it gets updated whenever the nodename database
is updated, so VMS users could always use that, if they just want the
same nodename database as MIM.
An alternative is also to suck down MIM::US:[DECNET]NODENAMES.DAT and
parse it yourself, and do whatever you want to.

Be careful that your SCSSYSTEMID and DECnet node number are the same or
it will be a mess. You have been warned!

Yes. As far as "global" nodenames are concerned. Of course, since anyone can have other definitions of their own, for any individual, they might have more information that MIM do not know about.
But MIM is the only machine which I keep the database of all nodes that I'm told about. Since DECnet do not force a global namespace, this is a totally voluntary database, as a convenience to those who care.
