When running a bind 4.x server, the slave will poll the master every X
hours, where X is the value of the "refresh after X hours" variable in the
SOA record for the zone file. Bind 8.x works a bit differently and that's
what *most* people are running. When you restart the master, it looks for
nameserver records in the zone file(s) and notify's the slaves that the
various zones have been updates and a properly configured slave (also
running bind 8.x) will load the updated zone(s) immediately. If there are
no nameserver records in the zone file, then it's back to the polling after
X hours. If you look at /var/log/messages on the master, you should see
this take place when everything is working properly:
hostname named[24913]: reloading nameserver
hostname named[24913]: Zone "mydomain.com" (file db.mydomain)
hostname named[24913]: master zone "mydomain.com" (IN) loaded (serial
2000073100)
hostname named[24913]: Forwarding source address is [0.0.0.0].1169
hostname named[24913]: Ready to answer queries.
hostname named[24913]: Sent NOTIFY for "mydomain.com IN SOA"
(mydomain.com); 2 NS, 2 A
hostname named[24913]: Received NOTIFY answer from [SLAVE IP] for
"mydomain.com IN SOA"
hostname named[24913]: approved AXFR from [SLAVE IP].2410 for "mydomain.com"
hostname named[24913]: zone transfer (AXFR) of "mydomain.com" (IN) to
[SLAVE IP].2409
You may also want to check the same file on the slave. Have you setup the
slave's /etc/named.conf file correctly so it knows it's a slave? Something
like so:
zone "mydomain.com" {
type slave;
file "db.mydomain.bak";
masters {
IP ADDRESS OF MASTER(s);
};
};
