So it's pretty simple. Im getting a ton of SERVFAILs randomly and I can
neither figure out why nor figure out how to get bind to give me debug
information about why. The documentation here:
https://kb.isc.org/docs/aa-01526 <https://kb.isc.org/docs/aa-01526>
Hurts my head to read and references stuff that I can't figure out where
in the documentation it is to explain what it is.
I took the exact document on that page and switched everything to
"debug" and I have reset the server, rebooted the server, nothing. Here
is the exact one line bind produces in its logs for the query that is
generating the SERVFAIL:
22-Apr-2025 01:08:17.138 queries: info: client @0x7ffa3cb78168
192.168.8.104#47099 (ksc.wiki): query: ksc.wiki IN A + (10.30.160.20)
Nothing. And here is the query-errors file:
geoff@NS1:/var/log/named$ cat query-errors | grep -i wiki
geoff@NS1:/var/log/named$
zilch.
So. what am I doing wrong here? Why can't I get any debug info out of this?
logging {
channel default_log {
file "/var/log/named/default" versions 3 size 20m;
print-time yes;
print-category yes;
print-severity yes;
severity debug;
"severity debug" is equivalent to "severity debug 1" and there's not
much extra information written at the first debug level. The KB article
you linked uses "severity dynamic" which uses the server debug level to
control what gets logged. You've already set that to 99 based on
replies elsewhere in the thread, so just fix the severity here and
reload named, and you should get all the logs you need to figure out
what's going on and then some.
