Cisco NML, was Re: [HECnet] HECnet mapping project

I believe the Ciscos have DECnet node numbers and run an NML equivalent (i.e. they respond to NCP commands) but I don't know much about them. Sorry; I don't have one. $ mcr ncp NCP>tell gw list known circuits %NCP-F-CONNEC, unable to connect to listener -SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node $ -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Getting a virtual cluster connected

I thought clustering over ethernet used DECnet. Nope...SCS, which is Systems Communications Services if memory serves. (is that right, Brian?) Completely unrelated to DECnet. Dunno which "Brian" you refer but SCS it is. I initially meant you, but now I recall (half drunk at the moment) that Brian Hechinger knows quite a lot about VMS clustering as well. :) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

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
