I think we need to get this working natively in IOS somehow. I don't want to generate a new config if someone's IP changes, although I *could* if I needed to.
I thought IOS supported CRON and scripting?
Assuming it doesn't happen all the time I guess that's not so bad, really.

Ok, cool.
Am I understanding this correctly that you will keep a database of all the Cisco devices, and when a new member signs up you will generate a new config for everyone ?
Exactly!
Anytime anyone new sends me the required info i'll generate a new config set and email it out to everyone (well, the script will)

I support full-mesh as well.

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.

2. Persuade someone who has a fixed IP to run the user mode
router, if you register your IP with something like DynDns then
the user mode router periodically checks for a change of IP.
Is the user mode router ready? I could deploy that..
[Rob Jarratt]
It has been used in a couple of configurations now and
seems to work
OK, I use it permanently now. You could try it and if it does not
work for you it is only seconds to switch back to the bridge.
Oh I was going to run the bridge as well, act as a sort of
connections
hub (Bridge, MULTINET on GORVAX and the user mode router).
What OS does the user mode router run on?
sampsa
It runs on Windows (as a Windows Service) and it runs on linux (as a
Daemon). I built the linux version on the Raspberry Pi using a flavour
of Debian. I think it has been built on FreeBSD too.
Regards
Rob
Would it run on NetBSD???
Not tried it so I don't know. I am not really very knowledgeable on all the
different Unix flavours, but the code does not do a lot that is special so
it should work. Try building it, if it doesn't compile or work let me know
and I will build a NetBSD virtual machine and get it working.
Regards
Rob

persuade someone who has a static IP to peer with you. But the SIMH
emulation does actually do a fresh DNS lookup if the connection goes down,
so a change of IP would work in any case.
Cory, any progress on the Cisco dynamic IP thing?
Haven't had the time to poke at cisco scripting lately. Been too busy migrating to VMWare. I should have time later tonight. I'll let you know my progress.
