[HECnet] Configuring py-decnet.

If anyone else has responded to this e-mail and hasn?t received back a response from the list ? it?s because the e-mail is too large. Reply back to this message as I?ve trimmed it down. Supratim ? I went to reply back to your message below. Apparantly ?LOL? translated into Swedish is still ?LOL?

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: http://powerdog.com/addrconv.cgi and Peter has already done one of the calculations for you below. cheers, Wiz!! -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner <owner>- hecnet at Update.UU.SE] On Behalf Of Peter Lothberg Sent: Monday, 24 August 2020 6:43 AM To: hecnet Subject: Re: [HECnet] Configuring py-decnet. 59.53 is aa00.0400.35ec ----- Original Message ----- From: "bqt" <bqt at softjar.se> <bqt at softjar.se> To: "hecnet" <hecnet at Update.UU.SE> <hecnet at Update.UU.SE> Sent: Sunday, August 23, 2020 4:32:37 PM Subject: Re: [HECnet] Configuring py-decnet. Um, Thord. You do know that DECnet expects very specific MAC addresses to work, right? Johnny On 2020-08-23 22:29, Thord Nilson wrote: 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.
