I have a PowerDNS 3.3 server installed on Ubuntu 14.04 (for testing).
It should be master only. No slave exists.
I keep on getting this error:
Received NOTIFY for mydomain.com from 188.8.131.52 but slave support is disabled in the configuration Received unsuccessful notification report for 'mydomain.com' from 184.108.40.206:53, rcode: 4
220.127.116.11 (modified in this post) is the WAN IP of the PowerDNS server.
Here my pdns.conf
allow-axfr-ips=127.0.0.1 allow-recursion=127.0.0.1 config-dir=/etc/powerdns daemon=yes disable-axfr=no guardian=yes include-dir=/etc/powerdns/pdns.d local-address=0.0.0.0 local-port=53 master=yes module-dir=/usr/lib/powerdns setgid=pdns setuid=pdns socket-dir=/var/run version-string=powerdns webserver=yes webserver-address=192.168.178.33
To my understanding,
slave=no is per default and no slave is allowed for axfr, so PowerDNS should not receive any notification at all.
Or what is this message about?
