Correct: the master must be a master, and the slave a slave. :) Zones
are transferred via AXFR.

Don't know offhand (and I'm too lazy to look it up), but the chapter on
PowerDNs in http://mens.de/:/book may help you. [Disclaimer: I wrote it.]

You mean the `domains' table.

A slave server will transfer a zone only if it detects the SOA serial on
the master server is higher than its own. So, when you update a record
in your master's database, increment the SOA serial number for that
zone's SOA record.
