24.1 Legacy Series / Re: 24.1 - DHCP server moves to KEA - implications?

« on: April 12, 2024, 11:02:17 pm »

@pkejval, I've just posted a update to my gist that should tackle points 1 and 2.

Now I need to add some logic to parse the kea dhcp ranges to pull the dns domains.

Thnks for the feedback pkejval. I already found several more issues with my version.
- when kea cleans the memfile, the inode nr does not change. So the tailing stops.
- sending a break, stops csv.dictreader from tailing the file.
- need to add parsing of the kea config to assign the correct dns domain to a range.

I'll try to improve over time, but for now its a WiP. Once I have something that's actually running, we can try to get it upstream.

It's far from perfect, but I hope someone finds this useful?

Thank you very much! This is most missing feature of KEA DHCP for me. You should try to upstream this into OPNsense.
I adjusted it little bit because it gave me double domain for some hosts: https://gist.github.com/pkejval/49ff234bb81da59fde6ca1b03f4d4240/revisions

Hi all,

I'm not really sure where to post this, but for my own purposes I rewrote the `unbound_watcher.py` script to ingest DHCP leases from kea instead of dhcpd and create DNS registrations. This breaks dhcpd compatibility but for me it brings the added bonus that I now have synced DNS registation on both my HA opnsense nodes. It's far from perfect, but I hope someone finds this useful?
