[Unbound-users] Issue with logs not logging

Wed Sep 4 15:23:24 CEST 2013


Greetings again all,

I'm having an issue where unbound isn't writing anything to the log-file
I'm specifying.
My end game is doing a short log of each query (for informational purposes
and testing)

my truncated config as it stands is this :

I've been reading the man pages and the documentation on the website and I
believe this is the proper method to create a specific log.

verbosity: 3 * for queries*
logfile: "/etc/unbound/unboundLog.txt"
log-queries: yes

Is there something I'm missing?  I've also taken ownership of the file
through chown for the unbound user.

Thank you in advance ,

here is the full truncated  config for perusing:


        # whitespace is not necessary, but looks cleaner.

        # verbosity number, 0 is least verbose. 1 is default.
        verbosity: 3

        # Set to "" or 0 to disable. Default is disabled.
