Hello BIND users,
(my apologies if this gets posted twice, I first sent to
bind-us...@isc.org<mailto:bind-us...@isc.org> instead of
bind-users@lists.isc.org<mailto:bind-users@lists.isc.org>)
I am running BIND 9.11.4 on CentOS 7, built with support for dnstap. I am
testing capturing of all DNS packets, including DNS update packets, but they
don't seem to be captured. Here are my named.conf options:
dnstap-output file "/tmp/dnstap.output" ;
dnstap { all ; };
I use nsupdate to send a DDNS update to my zone, which is added successfully.
However, the dnstap.output does not record the DNS update. I see only the
following three packets captured:
02-Aug-2018 16:24:37.365 AQ ::1:8145 -> ::1:0 UDP 38b

;; flags: qr; ZONE: 1, PREREQ: 0, UPDATE: 0, ADDITIONAL: 0

Why is the DNS Update packet not captured/logged?
Thanks,
