ISC BIND 9.12.3-P1 Question re: DNSSEC Zone Signing

[LeBlanc, Daniel James]

Thanks Mark for your quick response.

On page 29 of the Bv9-12-3-P1ARM I had seen the following, which is why I thought that I "needed" to have one of those statements:


" Using the auto-dnssec option requires the zone to be configured to allow dynamic updates, by adding an allow-update or update-policy statement to the zone configuration. If this has not been done, the configuration will fail."


I was looking to do fully automatic signing using auto-dnssec maintain;.  If that is not possible I could still live with an rndc-based approach if required.

I will try this out in the morning.

Thanks again!

You don’t need update-policy local.  In inline-signing mode named maintains its own copy
of the zone with the DNSSEC records in addition to the copy from upstream.  DNSSEC is
controlled by rndc.

The Hidden Masters are a proprietary product and unfortunately when used to sign the zones, the SOA records are not populated as expected.  As a result, I was looking into signing the zones within ISC BIND instead.  Reviewed the literature, came up with a plan and the required configuration changes.  However, things are not proceeding as I had hoped…
