I started to ask how to do something apparently non-standard - which
probably means I'm doing it wrong.
I'm locally hosting my domain records using the authoritative server and
also using a recursor. The recursor is configured with a list of
forward-zones. My master server just has the auth & recursor running (on
different internal IPs) - my slave server uses dnsdist in front of its
own instances of auth & recursor (I'm still getting used to dnsdist).
I include all that just in case it's relevant - but I had this issue
prior to dnsdist and prior to replication so I'm hoping not.
Anyway, after all that - when I make a change to a domain record using
pdnsutil or an external tool using the API - the changes are immediately
applied to the zone but are not immediately visible through the
recursor. To make that happen I need to either flush the cache or just
restart the recursor.
This is an issue when creating/updating ACME challenge records - I
haven't been able to totally automate the process. I need to introduce
lengthy delays, try manually applying the changes, restart the servers,
whatever.
So - either I'm just doing this wrong (likely) or I need to ask: is
there a way to make changes in the auth server immediately visible in
the recursor? Possibly by explicitly disabling caching for the internal
zones? Probably a bad idea but I can't think how else to accomplish
this.
