do you encounter any problems? because authoritative-only servers should not
be delayed by such sessions, only at DoS attacks.
another possibility is a misconfiration on your side that can be abused by
remote clients. This again leads to qustion - do you have any problems?
Now my plan is to plot the graph where i can see number of concurrent
session for incoming queries,
and the total number of sessions, also i get to know any sudden increase
will generate alert.
note that DNS has no sessions. The only behaviour similar to this is number
of concurrent TCP queries. But a small server can handle thousands of
queries per seconds without problems.
Is there systems do you recommend. i believe we can achieve this cacti.
I can recommend cacti.
