DNS Secondary server not updating
short description
Secondary DNS Server gets named notify from master but doesn't update even after TTL expires.
correct behaviour
Secondary DNS server should fetch new zone.
environment
Server OS: CentOS
Server OS version: CentOS 7
ISPConfig version: 3.1.13
log entries
On the master server:
Sep 12 10:30:03 de-pri named[28854]: zone lostroom.pt/IN: loaded serial 2018091212 (DNSSEC signed)
Sep 12 10:30:03 de-pri named[28854]: zone lostroom.pt/IN: sending notifies (serial 2018091212)
On the secondary server:
(old) Sep 12 09:36:02 de-seg named[1151]: client 173.249.53.238#47877: received notify for zone 'lostroom.pt'
...
(old) Sep 12 10:02:03 de-seg named[1151]: client 173.249.53.238#12705: received notify for zone 'lostroom.pt'
...
Sep 12 10:30:03 de-seg named[1151]: client 173.249.53.238#5571: received notify for zone 'lostroom.pt'
Both are using the exact same version. No server is mirroring the other. (That isn't a requirement I assume)
Querying master:
horus:~ mendesrm$ dig @de-pri.gdcltd.pt lostroom.pt SOA +short
de-pri.gdcltd.pt. admin.lostroom.pt. 2018091212 7200 540 604800 3600
Querying slave:
horus:~ mendesrm$ dig @de-seg.gdcltd.pt lostroom.pt SOA +short
de-pri.gdcltd.pt. admin.gdcltd.pt. 2018091001 7200 540 604800 3600
Thank you.
