Yes, this is exactly how I run a DNS master/slave system, although I use Bind as the master for historical reasons. Assuming you're setting up a slave using MySQL, If you've followed something like http://downloads.powerdns.com/documentation/html/generic-mypgsql-backends.html then you need to add an entry to the "supermasters" table to allow the Slave to honour things that the Master tells it. INSERT INTO supermasters VALUES ('192.168.1.1','ns2.example.com',NULL); This configures pdns to be a Slave for any domains that the master (IP address 192.168.1.1) tells it, via a notify, where it is listed as an NS record with the hostname "ns2.example.com". Pdns will add the domain to the "domains" table, then perform a zone-transfer to pull the domain data.
