Hi Knot folks,
I just tried to view https://www.knot-dns.cz/ and it gave me an HTTP 404
error. After trying to reload it twice, I got the front page, but the
other parts of the site (documentation, download, etc) are all still
giving me HTTP 404 errors.
Regards,
Anand
Dear Knot DNS and Knot Resolver users,
in order to unite the git namespaces and make it more logical we
have move the repositories of Knot DNS and Knot Resolver under the
knot namespace.
The new repositories are located at:
Knot DNS
https://gitlab.labs.nic.cz/knot/knot-dns
Knot Resolver:
https://gitlab.labs.nic.cz/knot/knot-resolver
The old git:// urls were kept same:
git://gitlabs.labs.nic.cz/knot-dns.git
git://gitlabs.labs.nic.cz/knot-resolver.git
Sorry for any inconvenience it might have caused.
Cheers,
--

As answered in
https://lists.nic.cz/pipermail/knot-dns-users/2017-July/001160.html
those .db files are not required anymore.
I should have read the archive first ;)
With kind regards,

Hi,
I am running Knot 2.5.2-1 on a Debian Jessie, all is good, no worries.
I am very pleased with Knot's simplicity and ease of configuration -
which are still readable as well!
I noticed recently that I am getting
knotd[9957]: notice: [$DOMAIN.] journal, obsolete exists, file '/var/lib/knot/zones/$DOMAIN.db'
everytime I restart Knot. I get these for all my domains I have confgured,
and there is one in particular providing my own .dyn. service :-) - so I
am a bit reluctant - just to delete it.
But all the .db files have a fairly old timestamp (Feb 2017) and about the
same. At that time (Feb 2017) I was running just one authoritative Master
instance, nothing fancy. lsof also doesn't report any open files. At
that time (Feb 2017) I was running just one authoritative Master
instance, nothing else.
Can I just delete those files?
Cheers
Thomas
Hello knot,
I have recently started a long over due migration to knot 2.* and I have noticed that the server.workers config stanza is now split into three separate stanzas [server.tcp-workers, server.udp-workers & server.background-workers]. Although this is great for flexibility it does make automation a little bit more difficult. With the 1.6 configuration I could easily say something like the following
workers = $server_cpu_count - 2
This meant I would always have 2 cpu cores available for other processes e.g. doc, tcpdump. With the new configuration I would need to do something like the following
$avalible_workers = $server_cpu_count - 2
$udp_workers = $avalible_workers * 0.6
$tcp_workers = $avalible_workers * 0.3
$background_workers = $avalible_workers * 0.1
The above code is lacking error detection and rounding corrections which will add further complexity and potentially lacking itelagence that is available in knot to better balance resources. As you have already implemented logic in knot to ensure cpus are correctly balanced I wonder if you could add back a workers configurations to act as the upper bound used in the *-workers configuration. Such that
*-workes defaults:
"Default: auto-estimated optimal value based on the number of online CPUs or the value set by `workers` which ever is lower)
Thanks

Hi,
I just upgraded my Knot DNS to the newest PPA release 2.5.1-3, after
which the server process refuses to start. Relevant syslog messages:
Jun 15 11:19:41 vertigo knotd[745]: error: module, invalid directory
'/usr/lib/x86_64-linux-gnu/knot'
Jun 15 11:19:41 vertigo knotd[745]: 2017-06-15T11:19:41 error: module,
invalid directory '/usr/lib/x86_64-linux-gnu/knot'
Jun 15 11:19:41 vertigo knotd[745]: critical: failed to open

Jun 15 11:19:41 vertigo knotd[745]: 2017-06-15T11:19:41 critical: failed
to open configuration database '' (invalid parameter)
Could this have something to do with the following change:
knot (2.5.1-3) unstable; urgency=medium
.
* Enable dnstap module and set default moduledir to multiarch path
