That logging is new and will only show up if you have the logging level set to show 'debug' priority messages (if you set the loglevel to the default, show messages greater than debug instead of all, they will not be logged) . There was a discussion in another thread about dnsmasq 'retired or failed' counts when you would dump the dnsmasq stats, so I added this debug level log. What is logged does match the stats dump., and may be retries (if the destination only shows up once) or fails (if you see it fail on multiple dns servers).I am getting a lot of dns errors, don't think I've ever seen even one before now hundreds.
Jul 28 18:16:21 dnsmasq[414]: server xxx: resp: 0x00 query failed for xxx
Jul 28 18:17:09 dnsmasq[414]: server xxx: resp: 0x00 query failed for xxx
Anyone else seeing this? Any ideas how to troubleshoot/ fix the issue?
It may help to mention I am not using default ISP dns servers.
One other hypothesis is that these may be returns where the TTL of the response is invalid. I tend to see these logged primarily for 'tracking' domains. Normally I see a fail count about 2% of my DNS queries.....others have seen up to 15% of the queries retry or fail. Either one can easily generate 100s of entries.
