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. Nice. I should have approbiate media and will give this a try. 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? My memory isn't best too, so don't worry ;) Primary intention is to bring up at least the simulated VAX 24/7. The other machines would run on occasional basis. As my DecNET experience is way too rusty best practice would be operating the simulated VAX as Endnode for start. It'd be greatly appreciated if Steve could help out with the Dynamic IP....
