[HECnet] Who's emulating?

[Jason Stevens]

It was pretty simple too...!
  
I kept my notes here:

And as you can see... it was pretty easy.

That should actually be pretty simple. Much more simple than any other kind of networking. Anyone should pretty much be able to hack that one together as long as they know just a little about programming for sockets, and have a basic understanding of ethernet.
No strange things needs to be done in relationship with any OS.

(I've been talking with John Wilson about adding this to E11 in the past as well...)

     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.
