DECnet happily existed on MUCH slower links, so I wouldn't expect the normal inter-router traffic to be too terribly high.
Setup SNMP and watch the activity on your interfaces and see how bad it is. I might do that here as well. I'm as good test bed as I've got no nodes online currently, just the router so I get to see just inter-router traffic right now.
I should add a tunnel link to you, 75.49.5.125 is my end. Let's make this mesh now. I have a link to Dave, too. I just need to figure out why I have high packet loss to dynamips instance.
You two should send me the info I need to get the mesh config generated. :)

kron is a bit of a hack. It's amazing it works as well as it does. :)

Probably better than my "ping it and if it doesn't respond, update DNS" idea.
The nice idea about your way was things would just "fix themselves" instead of requiring manual intervention, but oh well. :)
I'll probably get back to the automation of jamming configs into ciscos, so it may be less manual. I'm not 100% sure yet though, we'll see.

I think many participants have e.g. an ADSL connection with 1Mbit/s or
something like it. Would the continuous routing traffic cut a
significant slice of the bandwidth?
That's a really good question. We should probably get some of the
experts to answer that. :)
That being said, there is nothing says we can't do both. If anyone
doesn't want to be a part of the mesh just let me know and we'll pick
two locations to be hubs.
Anyway, the mesh idea sounds good. I vote for it. I think it has
benefits like better availability in case of power outages or HW
failures and better distributed traffic between the various areas.
I really can't imagine it's going to be a big deal, so a mesh definitely
is a nice thing. Not being dependent on any one site is a good thing. :)

Right, did you ever get that working though?
Haven't gotten around to trying yet, still getting all my VMs up

Ok, keep us posted. I'll poke at it myself as well.

Hi All,
I requested access to HECNET some moons ago. Due to family Business
and heavy Workload in my Day-Job I had to pause this project for a
while.
Now as things settled I am back with my SimH/Vax (running 24/7 on a
raspberry pi) and my Alpha (an Alphastation 255 I newly aquired).
There are Decstations in Storage too (these odd MIPS Boxes) - maybe
one of these could be connected too - provided there's DECNet Support
in Ultrix.
There is. You just need to find the distribution.
What I'm asking for are three Node-Numbers (I don't need a whole area
- NodeNames would be MINE, EMMA and JACK) and a bit of advice with
Multinet. I have only a Dynamic IP uplink and am absolutely
unexperienced with Multinet.
You need to figure out who to connect to first, then we can fix the node numbers. I have a terribly short memory. Who was it that could handle Multinet with dynamic IP? Steve?
Care to help out? Also, Wolfgang, do you want to set a level 1 router, or do you just epxect all your machines to be endnodes, and have each on have their own link?
Best Regards,
Wolfgang
