[HECnet] Configuring py-decnet.

Hi! Great! The System is Slackware 14.2 with kernel 4.10.13 running on bare iron. (moved to another machine not to mess so much with network on main machine) There is traffic on the virtual interface dnettap0 (see below)? but rsts does not seem to see the py-router. Is there some "magical" command to enable this or is it automatic? Any ideas? Best regards, Thord. The config i have now is, in simh: ---------------------------------------------- ; DECnet 59.53 set xq enable set xq type=DELQA ?mac=DE-18-6B-DB-21-F6 att xq tap:dnettap0 ;set xqb enable set xqb disable set xqb type=DELQA mac=96-72-A1-2A-E7-40 ---------------------------------------------- The dnettap0 virtual interface looks like this: ---------------------------------------------- $ /sbin/ifconfig dnettap0 dnettap0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> ?mtu 1500 ? ? ? ? inet 192.168.12.162 ?netmask 255.255.255.0 ?broadcast 192.168.12.255 ? ? ? ? inet6 fe80::a3d3:3542:9b47:9a19 ?prefixlen 64 ?scopeid 0x20<link> ? ? ? ? ether de:18:6b:db:21:f6 ?txqueuelen 1000 ?(Ethernet) ? ? ? ?

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.____ __ __ Cheers, Wiz!!____ __ __ __ __ *From:*owner-hecnet at Update.UU.SE <mailto:owner-hecnet at Update.UU.SE> [mailto:owner-hecnet at Update.UU.SE <mailto:owner-hecnet at Update.UU.SE>] *On Behalf Of *Supratim Sanyal *Sent:* Saturday, 22 August 2020 10:11 PM *To:* hecnet at update.uu.se <mailto:hecnet at update.uu.se> *Subject:* Re: [HECnet] Configuring py-decnet.____ __ __ I believe he is running?slackware 14.2 with 5.2.2 kernel and a pretty recent ____ Simh?6fdc4474____ ____ Lots of people seem to prefer Slackware as the host ... someday need to try it____ ---____ Supratim Sanyal, W1XMT____ 39.19151 N, 77.23432 W____ QCOCAL::SANYAL via HECnet <http://www.update.uu.se/~bqt/hecnet.html>____ __ __ On Aug 22, 2020, at 7:38 AM, David Moylan <djm at wiz.net.au <mailto:djm at wiz.net.au>> wrote:____ 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.
