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.

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. :)

I have a fixed IP and therefore my connection is very static. Unfortunately, my connection is only 1Mbit/s outwards. I'll check if it would be possible to upgrade it.

Hi, Wolfgang.

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
PS: This may be double posted. First submission was from a wrong email adress.
That would have been caught by filters and never showed up.

Ok, I'm motivated. Let's get this automated.
I've got a small bit of python I wrote to generate cisco configs for the
tunnels.
If you are interested in getting auto-generated tunnel configs please
send me the following information:
1) The email address you want new configs sent to
2) Your routers public IP address(es)
3) The source interface(s) for your tunnels in full interface text. re:
FastEthernet0/1
4) The cost you want your tunnels to be if you don't want them to be 10.
Once you've gotten your first config text from me delete all your
current HECnet tunnels and then apply the config text you'll have been
emailed.
Unless anyone objects, I'm starting tunnel indexes at 50.
Steve D. -- if you want a router let me know. I'm going to eventually
get off my ass and migrate to this 2851 which will free up the 1841. I'm
more than happy to loan it to you as long as I have no need for it.
(Which I doubt I ever will)
The one question I have for everyone is.... Do we do a full mesh or do
we choose 1-3 "hubs" to connect everyone to? If 20 people have cisco's
and we do a mesh that's 20 tunnels, FYI. I'm ok with that, but I want to
get an idea of what everyone else thinks.

Will do. Gotta figure out why I have high packet loss to it first.
Bah. It seems I somehow broke something and I don't know what my secret is what's the quickest way to reset it?
Editing the NVRAM file by hand, it seems. ;)
