Hi,
we've recently corrected two issues: the server crashed when trying to
reload configuration with duplicate zones and zone transfers scheduling
was broken, causing sometimes (but very rarely) some zones not to be
synced with master properly, so we are releasing the fixed version right
away.
Sources of this version are here:
http://public.nic.cz/files/knot-dns/knot-1.1.2-rc1.tar.gz
GPG signature:
http://public.nic.cz/files/knot-dns/knot-1.1.2-rc1.tar.gz.asc
Final v1.1.2 will be released in a week.
Kind regards,
Lubos

Hello,
final release 1.1.1 of Knot DNS was just released. We just fixed one
small bug since last week's release candidate. Now should be stable.
Enjoy and stay tuned for version 1.2, which should be out in late
November and will bring the long desired support for Dynamic Updates and
some other improvements!
Kind regards,
Lubos

Hello,
I have setup a KNOT dns server but I'm having troubles with the UDP
queries. The server is not answering to the UDP queries but it is
answering to queries in TCP.
The server is running on a CentOS release 6.3 (Final) and the
configuration file is the following.
*************knot.conf***********

Greetings. This seems a bit odd. I have a zone file with:
=====
$TTL 6
test79.example.com. IN SOA foo.example.com. dns.test79.example.com. ( 201209150 5m 1m 2w 5m )
test79.example.com. IN NS foo.example.com.
test79.example.com. IN TYPE79 \# 4 deadface
=====
Trying to compile it gives:
=====
Parsing file '/home/dns/Files/foo.conf', origin 'test79.example.com.' ...
/home/dns/Files/foo.conf:4: error: bad unknown RDATA
Parser finished with error, not dumping the zone!
error: Compilation of 'test79.example.com.' failed, knot-zcompile return code was '1'
=====
This zone file works fine in BIND, NSD, and PowerDNS. It seems that either Knot cannot use the standard mechanism for defining unknown RRtypes (RFC 3597), or it maybe has a different syntax. Clues are appreciated.

Hi!

I believe that is because of using of kill(2) in pid_running(). So I'm
wondering how unprivileged user can send commands to Knot?
Thanks in advance.

Hi,
second Release Candidate of Knot DNS 1.1 is out now. We slightly
improved and fixed the user manual, fixed two minor bugs:
- generating journal for IXFR when the zone contains IPSECKEY and APL
records in binary format,
- possible leak on server shutdown with a pending transfer
and fixed the behaviour of slave server using TSIG. It did not sign SOA
queries to master, causing it to fail the zone version check when
talking to Bind with allow-query configured to use TSIG key.
Source files are available here:
http://public.nic.cz/files/knot-dns/knot-1.1.0-rc2.tar.gz
GPG signature:
http://public.nic.cz/files/knot-dns/knot-1.1.0-rc2.tar.gz.asc
Packages will be updated soon at the usual place on http://www.knot-dns.cz.
Please provide us with any feedback before the final 1.1 release next week.
Regards,
Lubos

Dear Knot DNS users,
we've just released a Release Candidate of Knot DNS 1.1. The new version
brings a lot of enhancements and bugfixes which improve stability and
interoperability of Knot DNS. It also contains a complete User manual
for easier deployment. The manual can be either built from the sources
('make pdf' or 'make html'), or accessed online via Knot DNS website
(http://www.knot-dns.cz).
Here are some highlights of changes in the new version:
- Improved speed of incoming IXFR even more.
- Optimized loading of many zones.
- Option to disable authoritative ANY answers as a mitigation to recent
DDoS reflection attacks.
- Fixed some problems and leaks cased if an IXFR transfer failed (e.g.
because of malformed data).
- Improved malformed packet parsing and handling.
- Fixed answering in some special cases.
We also implemented an option to generate zone differences from zone
reload and using them for IXFR journal. Thus Knot DNS may serve as IXFR
primary master (until now, it needed to obtain the differences by a
transfer from some other master). However, this feature is only
experimental, so use it with care. We do not guarantee that the results
will be always good or that it won't compromise the stability of the server.
For full list of changes see RELNOTES in the source directory or here:

Hello list,
I found an article
http://blog.nic.cz/2012/07/19/zavazna-vzdalena-zranitelnost-v-dns-serveru-n…
which mentions "list of non-standard DNS queries" for test purposes.
Is it possible to obtain this list and related tools? I looked into latest
Knot sources tarball and I found nothing :-)
I'm developer of BIND 9 plugin and I want to explore and re-use mentioned
tests for configurations with this plugin
(https://fedorahosted.org/bind-dyndb-ldap/).
I'm not a member of knot-dns-users list, please add me to Cc in reply.
Thanks for your time.
