Hi. I have a two node active passive cluster serving webpages. When a
failover occurs, I have to restart named on the now active node because
the cluster Ip was not available when named originally started even
though I have listen-to the cluster ip listed in my named.conf. Is there
a way to make

You don't have to restart it. rndc reconfig will re-check the IPs on
the machine and re-listen.
the cluster Ip
Thanks for the quick reply. rndc reconfig has the same problem as a
restart. I need to automatically listen to the new ip address without
manual intervention. On Wed, 2013-06-05 at 09:14 +0100, Phil Mayers

Hi Paul,
BIND will rescan the interfaces automatically - I think by default every 60
minutes. If a listen-on address becomes available it should be used.
It would probably be better to automatically trigger a reconfig, but you can
lower the scan time with the interface-interval option. I

Better to write a script which would first check the availability of
Virtual IP before doing rndc reconfig during a failover. In case the
script does not find the VIP in the first run, you can put in a loop to
check for VIP for N number of times with N number of seconds interval.
The failover
Use IPv6 and listen-on-v6 { any; };. The IPv4 socket api doesn't have
the hooks to force the UDP replies from the correct address. The IPv6
socket api has more functionality.

For what it's worth, there is code to do this in other projects:
Hi all,I think I may be confused about a very basic DNS concept. Sorry if this has been asked before.1. I have a master and two slaves.2. The master server is the SOA for my zone. The SOA record points to the master server.3. Each of the two slaves are authoritative for my zone.4. There are 2 NS
Everything you listed is pretty close to accurate.
A couple points of clarification.
8) The master needs UDP/TCP 53 open to the slaves. Before a zone transfer
can happen the slave needs to get the SOA RR from the master to see if the
serial number has changed. This normally happens over UDP

The 'hidden master' setup is a very good strategy for a number of reasons.
I think the original description only derails a bit when using the term
'authoritative':
I'm being told our authoritative DNS
servers should not receive any queries, as well as DNS slaves
respond to queries.

You have unwittingly walked into a religious argument.

That's a neat trick, thanks Warren! I also do like prefixes, BTW (as can
be seen in the other thread referenced).
