I have following issue with Knot: when I try to stop it by command
/etc/init.d/knot stop then the daemon is still running. If i run command
knotc stop then it's stopped but immediately run again. If I kill it by
command kill, it's the same...
As I found the /etc/init.d/knot is not working at all and Knot is
probably run during boot by /etc/init/knot.conf and I'm not able to
control it. The "unkillable" proccess is named /usr/sbin/knotd -c
/etc/knot/knot.conf
My environment: Debian 7 AMD64, OpenVZ container, kernel
2.6.32-openvz-042stab092.2-amd64, Knot 1.5.0-1
I tried to install Knot on another older machine where is Debian 7 too
but upgraded from 6 and it's KVM virtual machine. There it works
correctly via init.d script and the proccess is named /usr/sbin/knotd
*-d* -c /etc/knot/knot.conf
Do you have an idea why it's working on older machine correctly and on
the second with OpenVZ not?
Thanks for any help.

hello,
i'm operating a small hidden master server (four zones spread out to two
external NS servers), and want to introduce dnssec.
so far, i have kept my zone files in /etc under version control, but now
knot starts overwriting them, which is kind of important because of the
serial number increments, but also removes file structure, and comments
and generally messes with the changelog.
i could not quite infer from the documentation what the recommended work
flow is in this situation:
* will things work if i just make the zone files read-only for bind?
* should i keep the original files separate and copy them over to the
knot-writable destinations for each refresh? if yes, can that be
automated from within knot?
in either case, i have to take care of the serial numbers. my current
numbering scheme (YYYYMMDDXX with year, month, day and per-day number)
produces sufficiently few automated changes that incrementing by 10 each
time i edit the unsigned file on one deay would work, but what is best
practice there?
best regards
chrysn
ps. please keep me in cc when replying, as i'm not subscribed to the

Hello Knot DNS users!
After two release candidates, CZ.NIC Labs proudly release Knot DNS 1.5.0
final. This new version differs greatly from the old 1.4 branch - we've
rewritten quite a big portion of our code, and we've built a foundation
for next cool features to come.
But you've probably read about the changes in 1.5.0 in the previous
release messages, so here's just a brief list of improvements that are
visible to users: Optional query modules (currently we have dnstap and
response synthesization modules implemented), lower memory footprint and
improved zone events handling (for those of you with problems with zone
expiring, 1.5.0 should not have this problem). We've also done a lot of
under-the-hood changes, with lots of refactoring and massive code
reductions. Apart from all this, we've been very busy writing tests -
our current test code coverage is around 75 percent.
Here are the changes we've made from 1.5.0-rc2:
Features:
- DDNS forwarding reimplemented
Improvements:
- Transfer sizes logged in bytes if needed
- Logging outgoing NOTIFY messages
- Logging unauthorized incoming NOTIFYs
Bugfixes:
- Zone flush planning after bootstrap
- Incorrect incoming AXFR message sizes
- DDNS signing changes were freed too soon, with possibility of stale data
- knotc remote control key handling

We've done all we could to test Knot DNS 1.5.0 on our end, now it's time
you gave it a try! We hope you'll be as happy with it as we are.
Today's thanks for bug reports go to Anand Buddhdev and Motomu Utsumi.
Have a nice day and thanks for using Knot DNS!
Jan

Hi Maren,
you should turn the explicit notification
both in bind and knot.
For Knot use "notify-out <slave1> <slave2>;" + "xfr-out <slave1> <slave2>;"
See the documentation:
https://www.knot-dns.cz/static/documentation/html/configuration.html#master…
For Bind use "notify explicit;" + "also-notify;", see:
http://www.zytrax.com/books/dns/ch7/xfer.html#notify

Hello,
after upgrading to new stable version 1.4.7 we noticed a problem with
zones, which are expiring (i've seen some bugfix -expiration timer). It
happened second time now, and i think its happening every week (7days).
Zones, which expired are selected randomly, count of expired zones is ~8.
expired zones are listed like this:
somezone.net. type=slave | serial=0 | bootstrap idle |
After manually refreshing zone everything works fine.
TTL is 86400 - 1 day
We are using knot as slave dns. Bind9 is master.
Thanks for some advices.

Hello everybody,
We're currently testing Knot for a slave server with a BIND master,
and we've noticed that NOTIFY messages from this master are not being
processed by Knot. As I understand, BIND uses a random source port for
NOTIFY messages, as a precaution against attacks. Also, if I
understand correctly, when I add a remote master to a zone in Knot, if
I don't specify a port for it then it defaults to 53-
This leads me to believe that Knot is rejecting NOTIFY messages from
the BIND master, because they come from an unexpected, random port. Is
this correct? Can this situation be rectified to allow NOTIFY messages
from random ports?
Thank you very much in advance.

Hi,
We are setting up to do zone generations of two separate hidden masters
which will take turns on the zone generation.
Public/visible DNS servers "should" get notifies from both servers and
select the one with the with the highest serial number.
I am planning to run bind on one server and knot on the other. On bind i
have the issue that it would not send notifies to the name servers until
I turned on "notify-soa yes;". However I realise that his will only
notify one single DNS server and introduces a single point of failure.
Does Knot have any issues sending the notifies. How do I go about
getting this done?
Regards,
Maren
