Subject: F32 bind9 split dns debug
hi all,
any dns pros in the house??
i am trying to debug a split view dns.
i am using F32 & bind9 where i have internal & external views.
internal network 10.0.0.0/24<http://10.0.0.0/24>, external
108.220.213.120/29<http://108.220.213.120/29>
what i think i am seeing is a refusal of query, but Why??
where can i find a query_log print-severity definition?
dig shows, ...
