Thanks for your answer.
I would like to discuss the remaining content in more detail: Please share
your opinion, the way you are doing
- Why have many dns soft, dns system don't support log query.
- Is monitoring log query on DNS Authoritive server really necessary? We
should or shouldn't log query on DNS Server. Enabling tcpdump on the server
reduces DNS server performance like enabling query log or not like ???
- How to monitor abnormal, and tracing in DNS without monitoring query
