[HECnet] Curious about DECnet/Python

[Keith Halewood]

Some late night replacements and I’ve converted the TAP handling to use the /dev/net/tun arrangement of the tap/tun facilities of raspbian (buster).
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.

Hi Paul,

Thanks for making this available. It looks fantastic. I’ll have a go at setting up a node.

Regards,

Keith

There are some, yes.  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.

Hi,

Ok, so I’ve noticed… and I’m curious about DECnet/Python. Are there any details?
