DNSSEC validation failed in Rocky Linux 9
The goal is to enable DNSSEC validation for applications that demand it. In Rocky Linux 9, systemd-resolved disables DNSSEC by default, leading to errors such as DNSSEC validation failed or DNSSEC not enabled. This default setting impacts services that rely on strict DNSSEC enforcement, including some browsers and custom resolvers.
Key constraints include the fact that systemd-resolved may be disabled in certain installations, with /etc/resolv.conf managed by NetworkManager or resolvconf instead. Administrators must decide whether to enable DNSSEC globally or leave it disabled and configure it manually for each resolver.
Unresolved decisions revolve around the documented recommendation for DNSSEC handling in Rocky Linux 9 and the potential side effects of enabling it system‑wide.
- What is the documented recommendation for DNSSEC handling in Rocky Linux 9?
- If we enable DNSSEC in
/etc/systemd/resolved.conf, will this interfere with NetworkManager's DNS management? - Are there any security or performance trade‑offs reported when DNSSEC is enabled system‑wide?
