    I have a query regarding DNS resolution in Linux. I have entered the DNS servers in the resolve.conf. But the client is complaining that there is intermittent resolution problems. But when I am checking with nslookup and dig not finding any issues. Is there any way i can check the historical DNS resolution errors as to find when these kind issues were happening.

      May be the issue with their network setup, try to use same dig and nslookup commands from other network sources and see any issues..

        Hi Ravi,

        Thanks for your update. Apart from this, is there any logs which I can investigate to find when the issue is happening. Since it is inttermittent issue and currentky the resolution is happening.


        • Ravi Saive says:


          Unfortunately, there isn’t any logs for dig and nslookup requests, you need to find out yourself the issue..

      Is your /etc/resolv.conf file has proper dns entries? If no, add your network DNS entries to this file and try again.
