Hi.
We updated our authoritative servers finally to 5.0.
Now we notice a (strange?) behaviour….
All Pdns server use mysql as backend, but not mysql replication.
When adding an entry on the master like i.e.
pdnsutil rrset add monfortedalba.de _token._dnswl.monfortedalba.de TXT „bla"
we find on the secondaries dbs (after notifying/AXFR) the following:
mysql> select * from records where domain_id = 23 and name like '%dnswl%';
+-------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
| id | domain_id | name | type | content | ttl | prio | disabled | ordername | auth |
+-------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
| 52228 | 23 | _token._dnswl.monfortedalba.de | TXT | "test" | 3600 | 0 | 0 | NULL | 1 |
| 52229 | 23 | _dnswl.monfortedalba.de | NULL | NULL | NULL | NULL | 0 | NULL | 1 |
+-------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
2 rows in set (0.00 sec)
On the master the databases only lists the added record:
mysql> select * from records where domain_id=28 and name like '%dnswl%';
+------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
| id | domain_id | name | type | content | ttl | prio | disabled | ordername | auth |
+------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
| 1783 | 28 | _token._dnswl.monfortedalba.de | TXT | "test" | 3600 | 0 | 0 | NULL | 1 |
+------+-----------+--------------------------------+------+---------+------+------+----------+-----------+------+
1 row in set (0.00 sec)
Is this behaviour intended or is something misconfigured on our side?
Thanks for any hint,
Christian
