How about a bridge translating HECnet's area 1 to an area unused in Italian net and translating Italian area 1 to an unused area in HECnet? Hmm. Problem is that node numbers travel around in so many places in packets that it will be rather difficult to get them all. You have the MAC addresses, but also routing vectors for both level one and level 2, and in addition there are probably other places where node numbers occur in different protocols. They definitely occur in several places in the NICE protocol. If someone wants to try to do this, I'll happily cheer him on, but I fear it will never work correctly...

What I should have said was... They could go that way, but if they are going to change their area number anyway, then why not pick one that is unused and link to that. A Multinet tunnel would be perfect in this case. -Steve From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Sampsa Laine Sent: Thursday, June 28, 2012 19:36 To: hecnet at Update.UU.SE Subject: Re: [HECnet] "Poor mans routing" and the Italian Hobbyist DECNET On 29 Jun 2012, at 02:37, Steve Davidson wrote: PMR works great with hidden areas!

That's exactly what an ATG (Address Translation Gateway) does. Although I haven't used it over TCP/IP (Internet in this case). Maybe it would work if it is configured in either end of a GRE tunnel. Could be worth testing. Kari I have started a bit of work to create a user mode DECnet router and I am sure that this functionality could be added at some point. I will certainly consider it as I progress. But progress is not going to be quick. Regards Rob

I'll have a try... i'm sure to have a 5.25 drive around here somewhere. Anyway back to the Ultrix/DECnet marlarkey. I found an image of a decnet tape, but i ran into the old PAK problem. So its installed, but won't work. Any idea on a way round this? Or should I just be content that TCP/IP works on it, and move on to something else... Linux DECnet on a Pi is high on my hitlist at the moment. On Fri, Jun 29, 2012 at 12:13 AM, Sampsa Laine <sampsa at mac.com> wrote: Can you DD the disks?

you should ebay it, it'll probably fetch 100+ usd. On Thu, Jun 28, 2012 at 5:16 PM, Tony Blews <tonyblews at gmail.com> wrote: The boxes say SCO Interactive. For the x386 platform.
