Warning messages does not contain domain name

by Petr Šťastný

Hi, the majority of warning messages does not contain particular domain name (zone name), so it is impossible to figure which zone file is wrong. For example: > 2014-01-23T20:13:07 [warning] encountered identical extra SOA record > 2014-01-23T20:13:07 [warning] encountered identical extra SOA record > 2014-01-23T20:13:07 [warning] TTL does not match TTL of its > RRSet.Changing to 19200 Can you please add zone names into all error and warning messages related to one zone? Thanks Petr Šťastný

Disable journals

by Petr Šťastný

Hello, I want to use Knot for master zones only without any DNS updates, so journal files are not needed. But they are created for every zone and it seems impossible to disable them. But this is bad in my situation when I want to serve 200000+ zones, because it creates 200000+ journal files in one directory (but they are never used). Should be possible to disable journal files or create them only in case of need or at lease divide them into more subdirectories? It would be also nice to be able to choose another directory for journal files in configuration. "storage" option is for both (zone files and journal files). Or explicitly state journal file path and filename in "zone" section. Thanks Petr Šťastný

Logging categories

by Petr Šťastný

Hi, I think there is something wrong with logging categories. Documentation says: > server - Messages related to general operation of the server. > zone - Messages related to zones, zone parsing and loading. I use Knot 1.4.1 with the following configuration: > log { > file "/var/log/knot/knot-server.log" { > server error, warning, notice, info; > } > > file "/var/log/knot/knot-zone.log" { > zone error, warning, notice, info; > } > > stderr { > any error, warning; > } > } Everything is logged only into knot-server.log and knot-zone.log is always empty. knot-server.log file contains: > 2014-01-20T21:45:12 Knot DNS 1.4.1 starting. > 2014-01-20T21:45:12 Rate limiting set to 20 responses/sec. > 2014-01-20T21:45:12 Binding to interface 0.0.0.0 port 53. > 2014-01-20T21:45:12 Binding to interface :: port 53. > 2014-01-20T21:45:12 Configured 2 interfaces and 1 zones. > 2014-01-20T21:45:12 Changing group id to '1001'. > 2014-01-20T21:45:12 Changing user id to '1001'. > 2014-01-20T21:45:12 Server started as a daemon, PID = 25371 > 2014-01-20T21:45:12 PID stored in > '/usr/local/knot/1.4.1/var/run/knot/knot.pid' > 2014-01-20T21:45:12 Server changed directory to /. > 2014-01-20T21:45:12 Zone 'xxxx.eu.' loaded (serial 2013042301) > 2014-01-20T21:45:12 Loaded 1 out of 1 zones. > 2014-01-20T21:45:12 Starting server... > 2014-01-20T21:45:12 Binding remote control interface to > /usr/local/knot/1.4.1/var/run/knot/knot.sock > 2014-01-20T21:45:25 Reloading configuration... > 2014-01-20T21:45:25 Zone 'xxx.eu.' is up-to-date (serial 2013042301) > 2014-01-20T21:45:25 Loaded 1 out of 1 zones. > 2014-01-20T21:45:25 Configuration reloaded. And the question is: why are messages related to zone loading logged in "server" category and not in "zone" category (which is said in documentation)? Thanks Petr Šťastný

Re: [knot-dns-users] 1.4.0 dumping zones with non-existent dates

by daniel.salzman＠nic.cz

Hi Anand, Never mind. I understand your situation. Initially, we had just timestamps in zone dumps. I prefer this, since it makes smaller dumps and it is faster to process such records. Afterwards, we turned it off due to incompatibility with Bind. Because Bind is unable to load these dumps if you need it. Is there still anybody who requires human-readable timestamps in zone dumps from Knot? If not, we probably disable this functionality.

Knot DNS 1.4.1 patch release

by Marek Vavruša

Hi Everyone, about a week ago, CZ.NIC Labs released the 1.4.0 and received some positive responses, but also discovered a few issues here and there. I'll try to summarize the important bits. Since the 1.4.1, OpenSSL >= 1.0.0 is required on configure as we ran into several issues with the older versions. If that means a problem for you, please let us know, we can always try to work something out. That also fixes compile failures on some platforms with OpenSSL < 1.0.0 Moreover, we've ran into a race condition when generating timestamps in the zone file. This affects both 1.3 & 1.4 users, so if you run Knot on slave with secured zones and experience a refusal to load a zone after reload, I advise you to rebootstrap the zones from the master. As for the other issues, we've fixed an empty APL record support and immediate zone file syncing if you use that (it didn't flush the zone correctly after resign and 'knot zonestatus' didn't handle this properly). All that plus more code coverage bugfixes and papercuts. Yet again, many thanks to our dear users for the bug reports, hints and nudges in the right direction. Last thing, as you can see, we've dropped the bz2 source packages. I hope that doesn't affect anyone, two should be more than enough. Here's a full change log: https://gitlab.labs.nic.cz/labs/knot/blob/v1.4.1/NEWS Sources: https://secure.nic.cz/files/knot-dns/knot-1.4.1.tar.gz https://secure.nic.cz/files/knot-dns/knot-1.4.1.tar.xz GPG signatures: https://secure.nic.cz/files/knot-dns/knot-1.4.1.tar.gz.asc https://secure.nic.cz/files/knot-dns/knot-1.4.1.tar.xz.asc Kind Regards, Marek, CZ.NIC Labs -- Marek Vavruša Knot DNS CZ.NIC Labs http://www.knot-dns.cz ------------------------------------------- Americká 23, 120 00 Praha 2, Czech Republic WWW: http://labs.nic.cz http://www.nic.cz

1.4.0 dumping zones with non-existent dates

by Anand Buddhdev

Hello Knot users, We discovered today that When Knot 1.4.0 dumps zones to disk, it sometimes writes out the dates in RRSIG expiry and inception fields like this: 20140230203521 Yes, that's apparently 30 February! If you later restart Knot, or reload it, it will refuse to load this zone, and begin returning REFUSED responses for it. I spoke with the good folk at CZNIC, and Marek quickly provided me with a patch, attached here. It turns off pretty-printing of the dates, so that the expiry and inception dates are written in unix time. This fixes the problem for us, so if you're running Knot in production, you may want to apply this patch too. We don't yet know where this bug is, but needless to say Marek and his colleagues are investigating, and I'm sure a proper fix for it will appear in due course. Regards, Anand Buddhdev RIPE NCC

Knot DNS 1.4.0 released!

by Marek Vavruša

Hi Everyone, I hope you had a terrific Christmas. Now, I know it's all work, but after some time spent in the release candidate, CZ.NIC Labs are proud to release Knot DNS 1.4.0 final version. There have been a several bugfixes, odds and ends since the last release candidate. Namely NSEC3/transfer related bugs and case sensitivity of QNAME, there's a link for an exhaustive list of changes below. But allow me to reiterate what's new since the 1.3 version. Shall we? Since the first beta, we have brought a new major feature on the table. A technology preview of an automatic DNSSEC signing. Now, since it's not a final product, there are still a few shortcomings; mainly key management and auxiliary tools missing. However, that shouldn't stop you from giving it a try! We've written a short "how to" on our wiki page here: https://gitlab.labs.nic.cz/labs/knot/wikis/dnssec-quickstart But it's really as simple and creating signing keys and setting "dnssec-enable on;" There are few more enhancements like IDN in the utilities, zone serial policies and fancier zone file printout. Plus a lot of changes under the bonnet. Say for example the memory consumption, which is significantly lower (~35% for our large zones). We've also doubled our (continuous) efforts in producing both unit and operational test cases, not to mention Knot DNS being kindly accepted in the Coverity Scan program for open source software. We've also spent some time on other related projects. Say the comparison of the authoritative name servers, that you can find here: https://www.knot-dns.cz/pages/benchmark.html The whole effort is open source, you can try it yourself or even create new test cases, any feedback is welcome. https://gitlab.labs.nic.cz/labs/dns-benchmarking With all that, the work is far from finished. We're going to further polish the Knot DNS 1.4 features and prepare a new version at the same time. By the way, we have a few surprises for you in that department as well. Last but not least, we and the whole CZ.NIC Labs would like to thank you, our users and supporters, who poured a lot of time into helping us shape the Knot DNS the way it is. It's truly appreciated.

Feature request: inherit xfr-in, xfr-out, etc from "zones" section

by Anand Buddhdev

Hello Knot devs, The Knot zones directive allows some options at the top-level (such as "storage", "disable-any", etc). However, the following options can only be specified per zone: xfr-in xfr-out notify-in notify-out update-in Could you make it so that these options can also be specified at the top level so that all zones specified after can inherit the same options. This is useful when I have the same master or set of masters for a whole bunch of zones, and I don't need to specify them each time for each zone separately. Regards, Anand

Knot 1.4.0-rc2 is case-sensitive!

by Anand Buddhdev

I exposed Knot 1.4.0-rc2 to real queries, and noticed it was giving REFUSED responses for a significant number of queries. Digging further, it looks like the QNAMEs were mixed-case, such as: 42.234.11.86.In-adDR.ArPA So here's where I discovered a show-stopper bug: # dig +norec @193.0.9.5 ptr 42.234.11.86.in-addr.arpa ; <<>> DiG 9.9.4-P1 <<>> +norec @193.0.9.5 ptr 42.234.11.86.in-addr.arpa ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 16021 ;; flags: qr; QUERY: 1, ANSWER: 0, AUTHORITY: 4, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;42.234.11.86.in-addr.arpa.
