One of the suggestions that was posted here for how one might connect to HECnet was to create a GRE tunnel to a cooperative node, using either a Cisco router or an emulation of one. I don't have any experience with Cisco stuff, and I don't feel enthusiastic about going down that particular rabbit hole just yet if I can find another approach more in line with my experience and interests.
I see that there is GRE support in Linux, at least for IP-in-IP tunneling. Do any of y'all know if Linux's GRE support can tunnel non-IP protocols such as DECnet Phase IV? So far I've only succeeded in finding documentation about how to set up IP-in-IP tunneling, and I don't understand what's going on under the hood yet.
Since I want to keep my local DECnet traffic local, my current goal is to set up a VAX/OpenVMS simulation under SIMH to act as a DECnet area router (and provide other services to my real VAXen, too). I plan to use a SIMH emulation so I can leave it up all the time to maintain presence on HECnet without running up a big power bill. My real VAX-11/730 and other future vintage DECnet-speaking hardware would only graze on electrons infrequently, and mostly during colder weather.
Hi
Got OS X Lion running inside a VirtualBox - obviously the first thing I want to do is to see if it can talk DECnet. The forums mention a ?Pathworks for Macintosh? product. Does anyone know where to get a copy of it?
Thanks

Hi there, everybody! I'm a vintage computer collector in southern California, USA, and I'm interested in joining HECnet. I thought I'd introduce myself and then ask some questions on the mailing list before I ask to join the network.
One of my favorite computers in my collection is a VAX-11/730 system with an R80, RL02, TU81 and DECwriter III. It has an ethernet card, and it came with OpenVMS 7.3 on the R80 and VMS 5.3 on an RL02 pack. I don't seem to have a single good TU58 tape, even after repairing the capstan rollers in the drives, but I can boot up the computer via tu58em. I've shared the boot-optimized console tape image I put together, as well as an image I created of the CRDPACK RL02 pack that came with the system:

It's been a couple years since I fired up that system, but I recently had another burst of interest and began setting up some VAX emulations in simh. I have a simulated VAX-11/785 running in simh on a BeagleBone Green (a little embedded computer board, similar to the Raspberry Pi). I plan to leave it running as a full-time VMS presence at home, so it can be up on HECnet all the time. It would be a natural host for any bridging or routing I need to do, and I plan to use it as my main bridge between my modern computers and anything I have speaking DECnet. I have TCP/IP set up on it so I can FTP files on and off of it from my modern systems. The 11/730 won't be powered up very often, and probably mostly during winter!
I have plans to restore a heap of parts that I have into a working PDP-11/44 eventually, and I suppose it should be able to run RSX-11 and also visit HECnet?
I expect that I'll probably get more DECnet-capable hardware in the future. I'd like to get a PDP-11/73 someday, and I'm curious about those little QBUS MicroVAXen. Maybe I should add a VAXstation to the mix, too?
So now it's time for me to figure out how to join HECnet. I gather that my best options would be to either use the bridge program, or to set up my VAX-11/785 emulation to bridge things somehow.
If I use the bridge program running on a Linux box, can I configure it to only bridge traffic to/from the rest of HECnet? I don't want the traffic between my local DECnet nodes to leave the house. If the bridge program forwards all DECnet packets that it sees, then maybe I should learn how to set up my emulated VAX-11/785 as a router instead?
And now for the really tough question: Once I add my systems to HECnet, what can I *do*? I'd like to join HECnet just because it's there, but it would be swell if there's more fun stuff to do.
