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:
https://git.nic.cz/redmine/projects/knot-dns/repository/revisions/v1.1.0-rc…
Source files can be downloaded here:
http://public.nic.cz/files/knot-dns/knot-1.1.0-rc1.tar.gz
GPG signature:
Packages will be available soon on http://www.knot-dns.cz.
Kind regards,
Lubos

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.

Hi,
I am having difficulties running knot on an dualstack host. I want Knot
to listen on all IPv4 and all IPv6 interfaces. I am using this
interfaces section in config file:
interfaces {
allv4 { address 0.0.0.0; }
allv6 { address [::]; }
}
Using this config, Knot listens only on v4 address and gives an error
binding the v6 address:
2012-07-27T13:21:44.646094+02:00 Binding to interface 0.0.0.0 port 53.
2012-07-27T13:21:44.646197+02:00 [error] Cannot bind to socket (98).
2012-07-27T13:21:44.646233+02:00 [error] Could not bind to TCP interface
:: port 53.
2012-07-27T13:21:44.646240+02:00 Binding to interface :: port 53.
Changing interface order the other way around results in listening on v6
only with same error, yet also v4 connections are accepted, probably due
to IPV6_V6ONLY socket option not being turned on by Knot.
When I tried changing listening port on either line, problem
disappeared. I am using Debian package, version 1.0.6-1~bpo60+1.
Cheers,

Hi there,
thanks for the report! It's true that Knot DNS actually imposes quite
rigid rules to domain names. We will probably change that in future. But
we forgot about the RFC 2317 case, so thanks once more for the notice.
Will add support for / in domain names in the next release - that should
suffice.
Regards,
Lubos

Hi,
Is there any frontend for knotdns? We have different kind of users and for
non technicians is more difficult to manage from command line.
¡Thanks!

As long as invoke via knotc and easy query via dig, the

Hello again. Here's another one.
I noticed that zone data contains relative notation such as
'@' but no $ORIGIN causes error.
knotc checkzone says:
-----

And knotc compile says:

It complains even though it knows that "origin 'example1.jp.' ...".
Is this behavior by design policy? Or I wish it to be
enhanced.

Hello,
Yesterday I replaced one of my authoritative servers with knot 1.0.5
(previously powerdns). I am already delighted by the simplicity of knot,
so thank you for a nice piece of software.
I tried some configurations and noticed that I was unable to correctly
run as an unprivileged user. It seems that the problem is:
- start knotd as root.root
- create empty pidfile (owned by root.root)
- drop privileges to user 'knot.knot'
- write pid to pidfile (and fail doing so)
- log error:
2012-06-11T22:23:06+02:00 julie knot[31184]: [warning] Failed to create
PID file '/var/lib/knot/knot.pid'.
2012-06-11T22:23:06+02:00 julie knot[31184]: Server started as a daemon,
PID = 31184
2012-06-11T22:23:06+02:00 julie knot[31184]: [warning] Server running
without PID file.
When stopping knotd later on, the following is logged, and knotd does
not stop running.
2012-06-11T22:23:38+02:00 julie knot[31210]: [warning] Server PID not
found, probably not running.
I guess that either the pid file need to be chowned to the unprivileged
user before privileges are dropped, or the pid needs to be written to
the file earlier. Note that the file *is* created (despite the error
messages saying something else), but it is empty.
Kind regards,
Tom
