<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">In the past few years I was forced to move across to something different – PHP was the thing that forced me to move across.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>

etc). I can build up a Slackware VM and config it up so I can provide you with very specific notes.<o:p></o:p></span></p>

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.<o:p></o:p></span></p>

<p class="MsoNormal">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.<br>
I was able to move from my old Cisco router across to PyDECnet and maintain all of my existing GRE tunnels with no reconfiguration.<br>
<br>
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.<br>
<br>
Thord - I have a similar setup, but I'm running VMS. Here's how I have it setup:<br>
<br>
- my host running is Ubuntu 18.04.2<br>
- physical Ethernet (it's called "ens160" because I run VMware)<br>
- tap interfaces for each of my VMS simh machines<br>
- a tap interface for PyDECnet<br>
- I bring all of my tap interfaces and my physical ethernet together into a bridge interface<br>
- the bridge interface has my IP address bound to it.<br>
<br>
PyDECnet is setup with the first circuit connected to the tap adapter I reserved for PyDECnet above.<br>
I then have circuit entries for each of the connections to the other area routers and end nodes I am connected to on HECnet.<br>
<br>
I assume that you should be able to achieve the same with RSTS/E on simh.<br>
<br>
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.<br>
