I've been running it out here on an old U10 running base I do builds on.
It's sol9 9/04 with studio 11 and 9_Recommendeds fed to it. 1gb ram and
a 40gb disk. SIMH hasn't crashed yet. Idle seems to be functional also,
it's idling at about 17% cpu on a 2Mb cache 400Mhz UltraSPARC-IIi
running at 440Mhz. CPU is a v12 impl, Mask 9.1 in prtdiag -v.
It's been fluctuating between 91% usage and 17% for the last few days.
Only other oddity is that the machine has swift with a second HME and
scsi on it (tape). No probs thus far. I have dedicated the internal
happy meal for the TAP devs.
Al.

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.

I seem to remember that DECnet support now have been dropped from Linux.
So it might not be in there anymore, if you look at recent versions.
Huh? Nope, works fine here, on a two-week-old Mint installation.
(Mint is Ubuntu with Canonical's bad decisions un-done)
I've also had less than stellar results from trying to talk from Linux
to RSX. So it might not work absolutely right under all conditions.
Developers mostly (it not only) had VMS machines to test against...
I've had similar results talking to RSTS/E DECnet. From the little
bits of old mailing list traffic I've seen, I'd guess they'd be happy to
have it work with other platforms' DECnet implementations, but finding
people with machines to test against is tough outside of this crowd.
I plan to contact the developers when I have a little time and offer
to do some more formalized testing against RSTS/E and RSX and get them
feedback, and possibly fix some of the issues.
This really needs to happen.

I reckon it could be done with a single interface.
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?

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....
-P
"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..

Just some fun details...
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
IOS
If you know of any errors in this information, more fun facts, or anything else you'd like to share, feel free to do so.
