[HECnet] Curious about DECnet/Python

So I?m keen to know ? what changes did you make? I?m running a test box under Ubuntu 18 which is very similar to Debian Buster. When I use pydecnet with a line such as: circuit tap-0 Ethernet tap:tap1022 --random-address pydecnet complains that it can?t find the device. Apart from /dev/net/tun I can?t find any suitable reference for pydecnet to connect to. Was this major code lifting? Or some small subtle changes? Very interested to see what you?ve done. Cheers, Wiz!!

So if you have an arrangement such as this in /etc/network/interfaces: auto lo tap1 tap2 br0 iface lo inet loopback iface eth0 inet manual iface tap1 inet manual pre-up ip tuntap add tap1 mode tap user simh iface tap2 inet manual pre-up ip tuntap add tap2 mode tap user simh iface br0 inet static bridge_ports eth0 tap1 tap2 bridge_fd 0 address ?? netmask ??. gateway ??. Then the pydecnet config line: circuit tap-0 Ethernet tap:tap1 --random-address will connect. I?ll do some more testing.

It looks fantastic. I?ll have a go at setting up a node.

You can find the code and documentation -- admittedly somewhat brief -- on my Subversion server at svn://akdesign.dyndns.org/pydecnet/trunk/pydecnet . Very briefly, it's a DECnet implementation implemented entirely in Python 3, the full stack (including some applications). Phase IV, but unlike others it will talk to Phase II nodes. For that matter, it can be run as a Phase III or Phase II node if you like. There currently isn't a formal kit; you can install it from the Subversion working directory, or run it directly in there if you like. See doc/*.txt for details. Feel free to email me with questions, and of course any bug reports. paul On Oct 10, 2019, at 11:59 AM, Keith Halewood <Keith.Halewood at pitbulluk.org> wrote: Hi, Ok, so I?ve noticed? and I?m curious about DECnet/Python.
