Cory already covered ipv6 and cisco.
I've been thinking about setting Paul's python DECnet router up. I'll do that next week. I think it can do tunnel like things. Paul?
It does Multinet and GRE. I discourage Multinet because it was designed by the clueless. GRE works well.
DECnet/Python does not itself do any tunnels. It will speak those protocols directly to the remote system. If you have to deal with NAT, the NAT gateway may be able to do the appropriate address mapping. If you need an actual tunnel, you ll have to set that up separately; for example, you could use IPSec if you want to.
DECnet/Python is work in progress, but at this point it should be good enough to do basic routing for Ethernet as well as GRE. It has SIMH 3.9 style data-only DMC emulation handling, but it doesn t yet do the newer full DDCMP support; that s on my to do list.

Yay! Works. But damn, that was slow. :-)
Also, seems like FAL on Ultrix-32 have some bugs. :-)
Thanks. One more system checked against RSX with my new fix in place.
If you need to do more testing I can move the instance to a bigger host.

No worry. Slow speed is not a big problem. I'm just doing silly tests anyway.
If anyone have sources for DECnet for Ultrix, I can report that DECnet/Ultrix have an Y2K bug for file timestamps.
That is version V4.0, which is not Y2K compliant. 4.5 was patched for Y2K compatibility, but I have not been able to find the DECNET kit for it.

Looks like there's no DMC on the PDP-10, no DMC OR KDP on the MicroVAX, and no KDP on the VAX780.
However, the PDP-11 has the DUP. Looks like I can use that as the go-between.
Wonderinf if this is an RSTS/E bug...or a simh bug.
Device XK0: does not interrupt - device disabled.
Probably a SIMH limitation. It s complaining about the KMC11. RSTS supports those only for use with the RJ2780 emulator; it doesn t use them with DECnet.
The message comes from the hardware scan code, where it looks around the bus looking for devices and makes them interrupt to learn what vector each uses. For the KMC11, it does that by loading a short program into it. That only works if the KMC emulation knows how to emulate a KMC well enough to run that program. If it emulates a KMC only as a KMC/DUP pair that speaks DDCMP, this won t work.
If you want a RSTS system to connect to your Phase III machine, you ll want to use a DMC (or DMR/DMP/DMV, they are all roughly interchangeable). In a sufficiently recent SIMH, the DMC emulation speaks real DDCMP so it should talk with a software DDCMP implementation, such as one that uses a DUP. Or, since it doesn t know sync from async, it will probably talk to a software DDCMP implementation that uses a terminal interface.

Ok. It was just a thought.
Well, you can still do it. I don't mind. It's just that it don't really improve things on a grand scale. But it could be useful for local people near you, or with special requirements that you could fulfill.
But from a pure traffic load point of view, there are no problems today. But since the whole thing is distributed anyway, it also means that you certainly can also contribute to the distribution.
So don't take me wrong. I did not intend to discourage you from chipping in.

No idea, but I seriously doubt it is anywhere near that.

I don't mind taking your word for it.
What do you all think? Do you think it might be a good idea to set up a
node on this colo to allow some (most?) people who have dynamic IP to
VPN into?
I will not stop you. People are free to connect more machines to HECnet, and if they route traffic, that is also ok. So just go ahead.
More access points in various places don't hurt.

I didn't mean I have a suite or something. I meant that I have a large
machine with a large transfer allowance.

There is no central point through which all traffic passes.

Hi,
Now I'm back, I need to get reconnected to HECnet and get some routing sorted out. Multinet never worked, and I lost my fixed IP so I can't use the bridge. Is anyone able to offer some kind of IP tunnel, maybe VPN or something?
Have a cisco box?
No, I have a Linux ARM machine, but no Cisco gear (not keen on having a lump of Cisco gear just for DECnet)
Pick up a 2524. Mine was $10 and it pulls about 22W. ;)
Have IPv6?
I honestly don't know if it works on this ISP line. I assume it does but I've never tested it.
If it does, you could do the bridge between me. I've got to do some hackery to autoupdate ipv6.
