[Pdns-users] PowerDNS Authoritative 4.6.2, how to log served responses (i.e. NOERROR, NXDOMAIN, SERVFAIL, etc)?

[frank+pdns at tembo.be]

Hi Dmitriy,

https://doc.powerdns.com/authoritative/settings.html#log-dns-queries <https://doc.powerdns.com/authoritative/settings.html#log-dns-queries> states that it logs "all incoming DNS queries", not the results.

If you want to log the results, you'll need to either increase the loglevel, tcpdump the results and parse those, or add something in front of the server (eg dnsdist) where you'd capture the result codes and log.
