[Pdns-users] DNSSEC Not Working for All Subdomains

Can you tell me if these are the correct steps to secure gtec-gru-gw.customer.a.aa? A listing of the records table is attached.

pdnssec rectify-zone customer.a.aa
pdnssec add-zone-key customer.a.aa zsk
pdnssec add-zone-key customer.a.aa ksk

Is this correct and is there anything else that I would need to do?

Thank you,

It works for www.a.aa but not gtec-gru-gw.customer.a.aa see below.   Is "dig +dnssec +multiline @ www.a.aa" the correct way to test it?  I have included listing of records data, see attachment.  I am using pdns version 3.0.1.

Yes, that's a fine way to test it. Do note that we recommend against DNSSEC operation on 3.0 and 3.0.1. Version 3.1 has a lot of important DNSSEC fixes. However, your problems are not related to those fixes.

Because this is a different zone (as we noticed in your dump), you also need to secure it separately. In DNSSEC, the boundaries between zones really are very important boundaries, and every zone has its own settings and keys.
