Subject: RE: [HECnet] Configuring py-decnet.
Hi Thord,
You also have two GRE definitions which looks wrong.
You should have one circuit definition for PyDECnet to listen on the tap interface and another for your tunnel to Peter.
I don't know what this line is for:
circuit gre-0 GRE 192.168.12.161 <-- This is real address to host machine.
You also have two network adapters on your emulated machine - if you setup a local bridge, there is no requirement for this.
RSTS > xq > tap interface > bridge
PyDECnet > tap interface > bridge
Ethernet interface > bridge
Configure IP address on bridge
Then configure PyDECnet to listen on the tap interface and run the GRE tunnel to Peter.
You can also use pcap as you have configured below which I understand works fine. I personally use the tap interface directly with the PyDECnet patch as posted earlier.
In my case, I have tap91 going to my emulated vax (I chose this because the vax is 35.91 and I wanted to use a numbering system that reflected this).
I have tap1023 configured for PyDECnet.
In my vax.ini file I have:
; this is decnet phase iv node 35.91
set xq mac=AA-00-04-00-5B-8C
attach xq tap:tap91
and an example pydecnet.conf:
circuit tap-1023 Ethernet tap:tap1023 --random-address
circuit gre-12 GRE 11.22.33.44 --cost 5
as posted just below, the MAC address must be the correct one for your DECnet host.
The example above uses my MAC address for my 35.91 node.
There is a conversion page here that you can use:
<a class="moz-txt-link-freetext" href="http://powerdog.com/addrconv.cgi">http://powerdog.com/addrconv.cgi</a>
and Peter has already done one of the calculations for you below.
cheers, Wiz!!

Um, Thord. You do know that DECnet expects very specific MAC addresses
to work, right?

I used to be a hardcore Slackware head. I ran everything from the
earliest releases on a 0.99 kernel back in the 90’s and used it for
all of my Linux work exclusively until around 2015.____
In the past few years I was forced to move across to something
different – PHP was the thing that forced me to move across.____
__ __
Slackware has the “you run the entire distribution and the latest
version” approach which is fine, but as I was using Linux more and
more for application server work, I starting hitting problems with
PHP. Slackware was moving up to newer releases of PHP all the time,
but I had some application code that only worked under earlier
releases of PHP. ____
__ __
It’s not possible to run multiple releases of PHP side by side under
Slackware without hard custom installs, but Linux distributions such
as Debian and Ubuntu handle it with ease.____
__ __
Back in the day I really enjoyed doing everything by hand, building
everything from source and custom configurations for clients, but
now I’m using Linux more and more for customer application and
appliance work, and I don’t have the time to mess around and need to
get on with the job as efficiently as possible.____
__ __
Slackware has a very basic packaging system, and no dependency
management. You are also reliant on other people writing package
install scripts (Slackbuilds) or you do it yourself. We’ve all
encountered compatibility issues, or library conflicts, or other
issues that require remediation. With a good package management
system (such as apt) you can remove the incorrect libraries and
replace them with new ones in minutes, but under Slackware I would
be manually cleaning things up and compiling new packages again. Fun
as a hobbyist, but a total time killer when you are performing tasks
commercially.____
__ __
I’ve had this occur with deployment work I have done – for example -
run up PHP 7.3 and finish the job, to find out that you really need
to be running PHP 7.2 for some required dependency and I can fix the
problem in minutes with a good package manager.____
__ __
Fundamentally Slackware is not designed to be “modular” whereas
Debian/Ubuntu and others have thousands of premade packages to drop
in place. Not to mention many commercial vendors who won’t release
code and binaries only and the bulk of them will support Debian,
Ubuntu and Redhat as their primary or only release platform.____
__ __
Sometimes this is a really good thing. Take projects like Unraid for
example – this is all based on Slackware. When you are producing and
supporting a storage appliance you want a reliable and solid OS
underneath.____
__ __
--____
__ __
Anyhow – back to our current topic. All of my original simh and
DECnet was all done under Slackware and I still have heaps of notes
on how I set it all up.____
__ __
Thord – if this is the platform you are running, let me know – and
also if you are running this as bare metal or under a hypervisor
(VMware ESXi, HyperV, Virtualbox etc). I can build up a Slackware VM
and config it up so I can provide you with very specific notes.____
__ __
PDP11 and VAX use the same networking in respect to the SIMH side of
things. I can’t assist with anything RSTS/E related, but I would
assume that someone on the list would be able to assist us if
something on your actual simulated machine required changing that
you were aware of how to do.____
__ __
Let me know your configuration and whether I can assist.____

PyDECnet certainly does GRE. That's why we all love Paul's work
so much. It contains support for GRE, Multinet and your bridge
code all in the one product.
I was able to move from my old Cisco router across to PyDECnet
and maintain all of my existing GRE tunnels with no reconfiguration.
From what I interpret, Thord is running an emulated RSTS/E
system on simh and wants to run PyDECnet on the same host to
establish a connection upstream.
Thord - I have a similar setup, but I'm running VMS. Here's how
I have it setup:
- my host running is Ubuntu 18.04.2
- physical Ethernet (it's called "ens160" because I run VMware)
- tap interfaces for each of my VMS simh machines
- a tap interface for PyDECnet
- I bring all of my tap interfaces and my physical ethernet
together into a bridge interface
- the bridge interface has my IP address bound to it.
PyDECnet is setup with the first circuit connected to the tap
adapter I reserved for PyDECnet above.
I then have circuit entries for each of the connections to the
other area routers and end nodes I am connected to on HECnet.
I assume that you should be able to achieve the same with RSTS/E
on simh.
Let me know if you want more specific details (and let me know
what your OS version etc is). I can provide more granular
configuration information on my setup which you should be able
to use as a template for your own setup.
Cheers, Wiz!!

Indeed I did. I must admit that the picture is unclear. If
