Oh yeah, I forgot to mention.
One of the motivators for #Duppy, was off-the-shelf compatibility with #letsencrypt and #certbot - certbot ships with an #rfc2163 plugin.
So if you are hosting domains for people in a database and want them to be able to easily use DNS validation to obtain certs... this makes that possible without custom software on the user's side.
#rfc2163 #certbot #LetsEncrypt #Duppy
... as far as I know *nobody* is using #Duppy yet, including me - I have yet to deploy it. For shame!
It's quite functional though, and I think it's super neat - it's both a #DNS server and an HTTP web-API server in one #Python process. The idea is for it to handle all your dynamic-DNS-update-API-server needs in one codebase.
I wonder if anyone in Fedi would like to take a look?
