So, who wants to do a tunnel to me with cisco?
Also, what ports/etc does this use, do you know? Is this a GRE tunnel?

Joe,
Could you explain how the TOPS-20 system is connected to your network?
Your mail indicates the ability to do a SET HOST from WOPR to TOPS20, is that right?
If so then there is DECnet connectivity between WOPR and TOPS20.
or am I missing something?

Verzonden: 10 januari 2012 03:49
I'll echo the sentiment of not wanting to sound like an AOL user.... With all of the recent, invigorating HECnet discussion, I am curious if anyone has a decent [approachable] resource for getting a TOPS-20 instance on the [HEC] net. I have a non-panda instance up (ARPAnet), and have a version of DECnet [apparently] installed, but no dice with HECnet connectivity. Worse case I guess I may use a captive account of sorts to gateway from WOPR:: to the 20x node via telnet.... but that just seems wrong in principle... Joe

Well, I've seen no answer on this topic from other members, so I'll try
myself. In truth I've no TOPS-20 DECnet experience, but I've it on TOPS-10.
BTW, I seem to remember that years ago there was a TOPS-20 host on HECnet.
.ncp tell sol sho exec
Node summary as of 11-JAN-12 12:00:09
Executor node = 59.10 (SOL)
Identification = Systems Concepts SF CA USA - SC30M - DN-20 4.0
State = On, Active links = 0
.
Unfortunately I don't have many suggestions on how you do it. You do need to use ethernet, so my bridge would be a potential solution, but you might also have a VMS box on the same ethernet segment, and let that one do your routing for you.
Unless I remember wrong, there is one or two files in the system which have all the configuration parameters needed. I could probably dig some stuff up, but I know there are way more competent people in this area around, so I'll try to refrain from giving half-baked advice...

I do know that TOPS-10 and TOPS-20 are quite dissimilar, but I've to say
that setting up DECnet on TOPS-10 was not so difficult, so I think that on
TOPS-20 it will be even easier, given the overall OS look and feel. After a
brief Google search, if I'm not wrong, it appears that you need at least
TOPS-20 V6.1 to partecipate in an Ethernet DECnet network.
On TOPS-10 I had just to load the DECnet tape contents into the relevant
directories (i.e. help files in HLP: executables in SYS: and so on) and to
rebuild the monitor to include Ethernet network support by following an
on-screen procedure not so different from an old Linux make config.
For help, I consider alt.sys.pdp10, Bitsavers archive and Trailing-Edge
repository to be the most valuable sources (along with many other tiny sites
you may discover by just using the right search terms with Google).
Are you experiencing some particular problem?
Bye, :)

The latter option makes it a bit difficult to read, even now and you've only
9 nodes on your map!
Still learning.
There's new version, HECnet_20120111.png ready.

Rok,
I just copied HECNET.PNG. It holds a lot of detail, more detail than I
intended to put in the map.
One question: area 44 has only my systems in it and they are all on the same
network, a switched ethernet. So a drawing either ought to sho a single line
with all nodes connected to it or point-to-point connections for all nodes.
The latter option makes it a bit difficult to read, even now and you've only
9 nodes on your map!
