Excerpt of message (sent 20 August 2009) by Mark Abene: While I have been running three public access emulated systems for a few years now (TOPS-20 on KLH10, RSTS/E v8 and 2.11BSD on SIMH), there are several problems with me getting on HECnet. 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. Could you get RSTS/E V10? If so, you could run DDCMP over an async terminal line. paul
