Will take a look at the specs, a raspberry pi DECnet router would be great!
I haven't followed this whole thread since I'm in a busy time right
now, but just a quick thought...if it can't easily be done with a single
physical interface, perhaps a virtual interface might do the trick?

Wow.

ps: it's older solaris, but stil!
Holy cow! I have NEVER seen that happen. (which is why I run it!)
How the heck did you do that?
Built and ran SIMH 3.9
3.8-1 works just fine (it's what i'm running now) and 3.9 runs fine in
my sol11 VM.
Did it have something to do with the networking perhaps, maybe a weird
interaction with the Crossbow subsystem? We already know that part of
that doesn't do things exactly the way we need them to, I wonder if
there are other issues.

Hmm. Sure. But if you go the Linux routing route, then you instead get
into the problem that it don't have a point-to-point connection to
another Linux box on the Internet...
If anyone makes a Linux implemenation, I'll suggest that it would be
made to support the Cisco/GRE and Multinet/UDP formats, and you could
also have Johnny's bridge on the other side....

"actual DECnet router" meant "actual DECnet router" :-) Until now I thought
this was something only available in a VMS router node.
VMS not required... MIM is an area router running RSX. :-)
But yeah, "DECnet router" really meant just that.
T10/T20 is routing-IV, if you want to burn kernel memory it can be
area router, but, on the KI10 we had batter use of the memory, like
talking IP....
It would be a fun exercise to turn the bridge into an actual DECnet router.
One day, when I have a lot of time I might even think about trying that.
Feel free. The specifications are out there, so it's definitely not an
impossible task. But I guess it will take some work. It would be very
nice if the bridge did turn into a WAN router...
Bliss to C or a blisse X86 code generator... ---:)

No, you have not misunderstood. You are just not getting the full
picture. Yes, the Cisco box will transport the DECnet frames inside
something. At the bottom there will be IP, but most likely the DECnet
frames are actually sitting inside UDP...
My understanding of it is that GRE is another IP protocol on the same level
as TCP and UDP rather than using UDP.
You could definitely be right on GRE. It was way too long since I
actually tried working with GRE to really remember much anymore...
GRE, L2TPv3, TCP, UDP, ICMP are all protocols transported in/by
IP. It's a 8 bit identifier.

(what is 120...)
As I have hacked my own copy around a bit to make it work on Windows, can
you tell me what the fix was as I may find it hard to locate your change?
Thanks

Hi all. I found a stupid bug in the bridge program, which I fixed.
Improved the code documentation slightly while I was at it. New version at
http://www.update.uu.se/~bqt/hecnet as usual.

I've got a Windows NT 4.0 VM up occasionally too..

As of today, there are 321 nodes in the nodename database.
They are spread out over 16 areas.
We have machines located on (at least) three continents, if I remember right.
While not online all the time, I think we currently have atleast the following OSes represented:
RSX
RSTS/E
VMS
Ultrix
Linux
OSF/1
TOPS-10
Tops-20
Windows XP

p.s. Retrochallenge registration is open. It runs for the month of July.
Would be great to see some entries from you guys.

Hmmm... Maybe a DECnet router on a Raspberry Pi....
By the way: any more thought about where and when for DEC Legacy 2012?
