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.

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.
