[Pdns-users] master receiving notifies from slave

[Curtis Maurand]

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.

Mar 8 16:34:30 sirius pdns[27219]: Received NOTIFY for maurand.com from 
192.168.100.1 but we are primary (Refused) Mar 8 16:34:35 sirius 
pdns[27219]: Received NOTIFY for maurand.com from 192.168.100.1 but we 
are primary (Refused)

On the master  (208.105.217.26) I have:

  52 | maurand.com           | NULL   |       NULL | MASTER |      
2023030804 | NULL    | NULL    |           50 | NULL    |

On the slave (208.105.219.27) I have:

| 17 | maurand.com           | 208.105.217.26 | 1678315385 | SLAVE 
|            NULL |         | NULL    | NULL    |

As I was typing out my cry for help, here, I may have solved this by 
upgrading the master to 4.7.3 from version 4.4.1 (which is what is in 
the debian repos), but after the upgrade, I still received a few more 
notifies after the upgrade, but It seems to have settled down.

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
