Single address limitation per interface and remote server

by Matthias-Christian Ott

I just successfully migrated a several zones from NSD to Knot DNS. The migration was straightforward and quick, but I limiting the number of addresses per interface and remote server to one doesn't make sense to me especially with dual stack hosts. This is more intuitive to me in NSD. What is the rationale behind the current syntax? Regards, Matthias-Christian

Knot DNS 1.2-rc1 finally out!

by Marek Vavruša

Hi Everyone, we're proud to announce, that release candidate for the next major release 1.2 is out! Apart from a couple bugfixes, it features full DDNS support (including update forwarding). There are a few limitations related to DNSSEC-signed zones, please refer to user manual for more information. Access control for dynamic updates could be configured in a similar fashion to transfers, using the 'update-in' keyword. Next major thing is an updated remote control tool. Basic commands for start/stop/restart/compile and checks are the same as they were, but the command for refresh/flush/status could be executed remotely given the right configuration. You can enable remote control interface with a new config section 'control', f.e.: control { listen-on { address 127.0.0.1@5553; } allow remote0; } You can also specify a remote with associated TSIG key for security reasons. Knot control tool then accepts host, port and TSIG key as a parameter, f.e.: $ knotc -s 127.0.0.1 -p 5553 status Key could be also specified in a file instead of a command line parameter. But that is just a tip of the iceberg. For more smaller features, like configurable TCP timeouts or LOC support, refer to RELNOTES and a user documentation.

Knot DNS 1.1.3 just released!

by Marek Vavruša

Hi everyone, it's been two weeks since the rc1 was released, and I'm happy to announce, that the Knot DNS 1.1.3 is finally out! The release candidate fixed a couple issues related to answering DS queries, parsing of improper zone files and a wrong ARCOUNT in some error responses when EDNS0 was enabled. As for every bugfix release, we recommend all 1.1.2 users to update, even if no new features were added. Enjoy and have a merry Christmas. Full list of changes is at https://git.nic.cz/redmine/projects/knot-dns/repository/revisions/v1.1.3/en… Sources: https://secure.nic.cz/files/knot-dns/knot-1.1.3.tar.gz GPG signature: https://secure.nic.cz/files/knot-dns/knot-1.1.3.tar.gz.asc Packages available at www.knot-dns.cz will be updated soon as well.

by Lubos Slovak

Hi, we've recently fixed some issues in Knot DNS, mainly answering to DS queries (thanks to reports by Phil Regnauld, Casey Deccio and Erwin Lansing!). Other fixes are listed here: https://git.nic.cz/redmine/projects/knot-dns/repository/revisions/v1.1.3-rc… After the usual one week, the final 1.1.3 will be released. Sources: https://secure.nic.cz/files/knot-dns/knot-1.1.3-rc1.tar.gz GPG signature: https://secure.nic.cz/files/knot-dns/knot-1.1.3-rc1.tar.gz.asc Packages at www.knot-dns.cz will be updated ASAP.

Problem with UDP queries

by Eduardo Duarte

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*********** system { identity "Yet.another.server"; nsid "Yet.another.server"; storage "/opt/knot_run/knot-minimal"; pidfile "/opt/knot_run/knot.pid"; user root; } interfaces { ipv4 { address 127.0.0.1@53; } ipv4 { address 193.137.197.25@53; } } remotes { ns-test01 { address 193.136.192.86@53; } ns-test02 { address 193.136.192.87@53; } ns-test03 { address 193.137.196.30@53; } ns-test04 { address 193.137.196.31@53; } } zones { zonetest-01.dns.pt { file "/opt/knot_run/zones/zonetest01"; xfr-in ns-test01; notify-in ns-test01; } zonetest-06.dns.pt { file "/opt/knot_run/zones/zonetest06"; } } log { file "/opt/knot_run/log/knot.log" { any all; } } ********************************** The output of the log file is ********knot.log****************** 2012-09-17T10:25:40.208574+01:00 Stopping server... 2012-09-17T10:25:40.210677+01:00 Server finished. 2012-09-17T10:25:40.211260+01:00 Shut down. 2012-09-17T10:25:40.230967+01:00 Binding to interface 127.0.0.1 port 53. 2012-09-17T10:25:40.231283+01:00 Binding to interface 193.137.197.25 port 53. 2012-09-17T10:25:40.232162+01:00 Loading 2 compiled zones... 2012-09-17T10:25:40.233783+01:00 Loaded zone 'zonetest-01.dns.pt.' 2012-09-17T10:25:40.237553+01:00 Loaded zone 'zonetest-06.dns.pt.' 2012-09-17T10:25:40.238983+01:00 Loaded 2 out of 2 zones. 2012-09-17T10:25:40.239044+01:00 Configured 2 interfaces and 2 zones. 2012-09-17T10:25:40.239078+01:00 2012-09-17T10:25:40.239111+01:00 Starting server... 2012-09-17T10:25:40.240688+01:00 Server started as a daemon, PID = 8599 2012-09-17T10:25:40.240772+01:00 PID stored in /opt/knot_run/knot.pid ********************************* And an example of the query's ********************************* [root@ns-test06 ~]# dig @127.0.0.1 zonetest-06.dns.pt +tcp ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.1 <<>> @127.0.0.1 zonetest-06.dns.pt +tcp ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 30969 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 5, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;zonetest-06.dns.pt.
