[comp.protocols.tcp-ip] tcp/ip services <--> decnet connectivity, help wanted

garvey@cmic.UUCP (Joe Garvey) (05/30/90)

I need to connect a DEC (decnet) system to an HP unix system. My objective
is to make the remote login, and file transfer services work.

I can make the required physical connections of the LAN's involved...
However, I assume a direct connection won't work. I need some kind of
protocol tranlator in the middle.

For a number of reasons, each machine must think it's working in its native
services (decnet or arpa-berkeley).

Can I use a PC and some netware?
Does someone make a translator?
Can I directly connect the two networks, and put some software package on
my HP (9000/370)? It's out of the question to add software to the
DEC machines (PDP/RSTS) ;-(.
I've got some PC's and terminal servers using the arpa-berkeley tools, what
about them?

Am I crazy? :-)

E-mail response preferred. ... normal stuff about summarizing ...

Thanx.

The easiest thing to do would be to get a DECstation 3100 (or something
else running Ultrix) and use the DECnet-Internet gateway software. I
don't know many product specifics, but I know that you can use it for
remote login and file transfer. You should also be running at least
DECnet/E V4.0 (RSTS/E V9.3) as previous versions had some problems
dealing with Ultrix, if I recall correctly.

I've always thought it would be *fun* to put up TCP/IP on RSTS, though.
It really wouldn't be that hard to do for someone that was good with
RSTS monitor internals.

I also spent a long time looking for a TCP/IP implementation for RSTS.
After giving up on that, I looked at the solution described above, i.e.
an Ultrix VAX as a gateway.  All you need to run on it is DECnet-Ultrix.
This automatically does conversion between DECnet protocols and TCP/IP
protocols (according to DEC). Get DEC's "Local Area Network Solutions
Guidebook" and read page 74.

Well, in the end we decided that this solution was too indirect and
ended up replacing our three RSTS systems with a VAX 6310!  Too bad
there wasn't a real TCP/IP solution for RSTS.  I kinda miss it...

Integrated Information Systems (IIS) which I believe is owned by CDC has
just ported a DECNET product for the HP9000 family.  I have seen it
working on both the 300 and 800 series, and it appears to be very
reasonably priced.

The only number I have for them is for the manager of Business Development
for that product.  He is Randall K. Barker at (513) 427-6379.
