Logwatch Unmatched Entries for named connection refused resolving

bindlogwatch

Using the default setup of Logwatch on RHEL 6 and the caching name server (BIND 9) package, my daily logwatch reports are filled with unmatched entries regarding DNS server errors.

What do I need to change in the configuration in order to either hide those errors or do I need to modify the RHEL6 options for their caching name server package (/etc/named.caching-nameserver.conf).

Best Answer

You're using Amazon AWS to host this machine; apparently, there are nameservers that refuse queries from AWS.

I think you have to use Amazon's provided nameservers instead.
