PDNS sends only NOTIFYs for SLAVE zones is slave-renotify is turned on (globally, or per zone in domainmetadata table).
So, if your SLAVEs shoudl not send NOTIFYs make sure to disable slave-renotify. If a PDNS instance slaves zones from a master, but also acts as master to other slaves, then you can fine tune NOTIFYs. I use "only-notify=" (empty value to disable all implizit NOTIFYs). Further I use "ALSO-NOTIFY" domainmetadata settings to specify NOTIFY targets per zone. regards Klaus Von: Pdns-users <pdns-users-boun...@mailman.powerdns.com> Im Auftrag von Curtis Maurand via Pdns-users Gesendet: Donnerstag, 9. März 2023 00:06 An: pdns-users@mailman.powerdns.com Betreff: [Pdns-users] master receiving notifies from slave Hello, I have a pair of powerdns servers running on a debian derivative equivalent to bullseye: Devuan chimaera. I am running pdns authoritative version 4.7.3 from the powerdns debian repo. Devuan does not use systemd. I'm using sysvinit. The upgrade removes /etc/init.d/pdns script which is not good nor can I find it in the sources even though the docs say it's in there. That's not really why I'm writing. The slave server is sending notifies for one, and only one slave domain maurand.com to the master and the master (a supermaster) is refusing them, but they are happening several times per second. Boths servers are behind NAT firewalls and that would be the reason for the private IP in the notify.

I searched around the net for answers, but I can't find any. I've been running powerdns for a very long time. Does anyone have any ideas what might be causing this? Thanks in advance, Curtis Curtis https://curtis.maurand.com
