Would there be any way to get pydecnet to work with a device that only had
wifi? I have one of those $20 RISC-V boards that can run Ubuntu, it'd be
fun to use that as a pydecnet bridge. It doesn't have built-in ethernet
although I suppose I could use a USB-Ethernet adapter.

to work in debian.

Yes, I think that would work, but since we're only interested in DECnet
In the script that starts up the simh simulation,
sudo tunctl -t tap0
sudo ifconfig tap0 up
/usr/local/bin/microvax3900 <startup script> # or whatever simh
you
prefer
then in the simh script
attach xq tap0
and in the pyDECnet config just add
circuit TAP-0 Ethernet tap:tap0 --single-address
In this setup pyDECnet will route DECnet traffic between eth0 and simh,
which
should be fine as long as you only want to do DECnet with whatever OS
you're running on simh. If you want to run IP traffic from simh (e.g. if
you're running Multinet or Johnny's RSX TCP package) then you should stick
with Keith's scheme.
