Actually, I think the DNSaaS term has come into vogue as part of OpenStack, where the (sub-)project goes by the name Designate. See https://wiki.openstack.org/wiki/Designate I don't know why the original poster would ask about it here, since Designate seems to be more of a management layer

Forwarders are selected based on an RTT(round-trip-time)-based algorithm, so none of this configuration complexity should be necessary from a performance/availability standpoint. The algorithm will choose faster forwarders over slower ones, and penalization/eventual-redemption of

Identify source of rndc reconfig command?

Hi all, after upgrading from Debian Wheezy to Jessie, bind9 receives rndc reconfig commands every 30 minutes. I've never seen this before. Some of my own scripts run rndc restart/reload after fiddling with network interfaces, but none of these is the source of the observed 30 minutes interval.

I believe you could implement what you're looking for with a reasonably-sophisticated software/hardware load-balancer technology and/or some number of virtual machines, no BIND code changes required. Personally, I don't like forwarding much at all -- I only use it where it's absolutely

Does the rndc protocol have a timeout? If so, what is it set to? I don't see anything about a configurable timeout interval in the man pages for rndc or rndc.conf. What I'd probably do is turn off rndc in named.conf, set up a dummy server to listen on port 953, which just accepts the

The first thing I would do is make sure only the users you want to be able to use the rndc key can read it. I would then generate a new rndc key and configure both rndc and named to use it. If that doesn't work generate a new rndc.conf file with a different name that refers to a new rndc key.

Additional, BIND is open source so you are free to modify it to see if doing so helps you. The forwarders are sorted in lib/dns/resolver.c. The grammer is defined in lib/isccfg/namedconf.c The forward table is constructed using the routines in lib/dns/forward.c which are called from
