Brian, the manual stuff was a duck tape solution - the once that don't show up send me their router + end node CSVs and update them whenever there's a change. For the mapping, it makes no difference where they came from and the format is stupidly simple anyway :) Sampsa

Nice and neutral. :-) As well as being very central so it's not too far for anyone. (Said half in joke, since I do realize the costs of actually staying here for a couple of days isn't cheap.) Not a fan of CH, way too expensive and kinda dull :) Beirut is too hardcore I guess, maybe one meet in CA and another in UK around the DEC Legacy event? Not that I'm that fond of the UK either, hence my impending departure.. sampsa Cm'on guys. Do you want a relatively cheap place, with good night life, (relative) safety and not-so-hardcore as Beirut? Come to Barcelona! ;)

Cisco DECnet info, was Re: [HECnet] HECnet mapping project

STUPI has nothing to do with it and doesn't know about it. Bob's right; these are GRE tunnels (Peter is a hard-core Cisco guru), both to Peter and to Brian H. (who is quite sharp with Cisco stuff as well!) So how can we do this...I don't think IOS implements NICE, but I'm sure its DECnet routing table can be pulled out via SNMP. Brian (Hechinger), I can set up a read-only SNMP community and your poller (when it discovers an appropriate router) can walk the tree, maybe? And either Sampsa's code can parse that output, or you can reformat it into a consistent format to hand to Sampsa? What do you think? (snmpwalk is your friend!) This is being written in python so I'm sure I won't have any trouble accessing SNMP. I hope. :) I have my router as well, but the more data points the better. I'm nowhere near looking into that just yet however. I will keep you all informed. :) -brian

You guys got off into the woods fast. :) I will look into non-dec router devices after we get the dec ones nailed down with my current code. I'm thinking possibly SNMP for the cisco devices, yes. Not 100% sure that'll work though. As to your router if you don't want to bother with NICE or SNMP just let me know how I remotely query your device. How that happens is up to you so long as it isn't silly. :) A simple API that shoots back something like JSON or XML is fine, for example. We'll talk later when I get to you. :) Just to cover something here, as far as non-bridge link I *will not* do manual stuff. That's just icky.

If the CISCO guys want on the map, it'll have to be manual for now.... You'll have the same problem with Rob's DECnet router... And possibly other equipment, or nodes that don't want to talk NICE. I have just downloaded the spec and will think about how easy it would be to add this to the router, not that anyone other than me uses it :-( Johnny

Getting a virtual cluster connected

by rok.vidmar＠gmail.com

The DECNET.TXT file obviously had incorrect (very old) information for area 42. The same is true for Area 3: Area 3 Patrick Caulfield Chrissie kindly resigned this area to me. -- Regards, Rok
