PowerDNS error with slave

  • 772

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 82.91.23.176 but slave support is disabled in the configuration
Received unsuccessful notification report for 'mydomain.com' from 82.91.23.176:53, rcode: 4

82.91.23.176 (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?

powerdns master slave

    You have set master=yes which tells PowerDNS to send notifications. It does not check sent notifications against the allow-axfr-ips list because transfers might not come from the notified IPs.

    If you want the NOTIFY to go away, set master=no.
