How Do I know I Have a Validation Problem on my RHEL server?

Solution Unverified - Updated -

Issue

  • I'd like to make sure that it is indeed some issue with my dnssec configuration out of which the dns queries are failing.
  • Since all DNSSEC validation failures result in a general SERVFAIL message, how do we know that it was related to validation in the first place?

Environment

  • Red Hat Enterprise Linux
  • dnssec
