Jason's "patch" is actually playing ethernet for you. So, even without any separate machine with the bridge program on, or even without a real ethernet port on your machine, your simh can have a simulated ethernet, which hooks into my bridge program, making the simh machine appear to be on the virtual ethernet segment created by the bridge program.

First, my host server is FreeBSD, and FreeBSD doesn't support multicast on tap network interfaces, nor have I heard about any plans to. Which means no DECnet. At some point I plan to migrate my emulators over to a beefy linux server, and linux does have the necessary support. Second problem, is that SIMH doesn't support any DDCMP-aware network devices, which means that even if I solve the first problem (it'll allow me to get TOPS-20 on DECnet), I don't have any way via SIMH to get DECnet/E working on my RSTS system. Call me crazy, but I just don't think I'll be paying 4,000 dollars for E11/linux. So that's out. -Mark Marc Chametzky wrote: The recent downtime thread has sparked much discussion about a variety of DEC (and perhaps some Compaq) hardware, but who among us is living in HECnet lives in software? I have two systems nominally connected to HECnet, both emulated. I have the SIMH VAX emulator running VMS (DUSTY) and I have Mark Crispin's Panda system running TOPS-20 (CALHAN). Both of these are running as part of virtual Unix systems (one Linux, one Solaris) on a single ESXi box. I've also played with a couple Alpha emulators from Stromasys (CHARON-AXP on Windows and CHARON-AXP NCE on Linux), but I've not set up a more permanent virtual Alpha system. I'd set up a virtual PDP-11 to play with as well, perhaps running RSTS/E, but it's been far too long since I've used a PDP-11 to remember how to set it up and maintain it. Same thing with VM/370 or z/VM on Hercules. It's sad how much I've forgotten over the years. --Marc -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
