Clustering does not depend on DECnet or TCP/IP! Really? 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. Brian (Hechinger) and I once discussed the possibility of implementing a similar clustering system within NetBSD. I think just implementing the SCS protocol itself would be a good start. I wonder if there's enough documentation out there to do it. What'd be really interesting is joining that to a VMS cluster. ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
