On old server with Ubuntu 12 and Bind 9.8.1
I got the following "notify" category log entries as expected (domain names and
IP addresses redacted):
27-Dec-2021 12:58:51.786 notify: debug 3: zone example.com/IN: sending notify
to 1.2.3.4#53
27-Dec-2021 12:58:51.816 notify: debug 3: zone example.com/IN: notify response
from 1.2.3.4#53: NOERROR
Log config in /etc/bind/named.conf.options:
logging {
channel transfer_logfile {
file "/var/log/named/transfer.log" versions 7 size 10m;
severity debug 6;
print-time yes;
print-category yes;
print-severity yes;
};
category notify { transfer_logfile; };
};
With new server Ubuntu 18 and Bind 9.11.3
there are no "notify" category debug log entries anymore. The log does only
contain entries of severity "info", e.g.
29-Dec-2021 12:00:33.475 notify: info: zone example.com/IN: sending notifies
(serial 2021021001)
Log config in /etc/bind/named.conf.options with Bind 9.11.3 is exactly the same
as on the old server with Bind 9.8.1:
logging {
channel transfer_logfile {
file "/var/log/named/transfer.log" versions 7 size 10m;
severity debug 6;
print-time yes;
print-category yes;
print-severity yes;
};
category notify { transfer_logfile; };
};
I tested with "severity debug 16" but that did not help.
I tested with "severity notice", that lead to the "info" log entries to
disappear, so there is just nothing logged anymore for "notify" category, as
expected.
I also run "rndc trace" six times, so in named.log was logged "general: info:
debug level is now 6" and did a zone reload, but again, no "notify" debug log
entries.
I also tested with "severity debug 6" in the default log channel, that lead to
debug log entries for categories like "database" etc., so debug log is
generally working.
How can I get the log entries "sending notify to ..." and "notify response from
..." back again in the "notify" category log?
Thanks and Best regards,
Hildegard
