On BIND 9.7.1-P2 I have in named.conf:
channel query-errors-log {
file "/var/log/named.query-errors.log" versions 3 size 200k;
print-category yes;
print-severity yes;
print-time yes;
severity info;
};
category query-errors { query-errors-log; }; // no default_syslog
Is this correct for logging queries that produce SERVFAIL?
I ran this query on the DNS server:
dns# dig klyuniv.ernet.in @t1dns2.anl.gov
; <<>> DiG 9.7.1-P2 <<>> klyuniv.ernet.in @t1dns2.anl.gov
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 7278
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

dns#
and there is nothing logged in
/var/log/named.query-errors.log
Am I doing something wrong? Thanks.
