Re: [knot-dns-users] Fwd: [knot-resolver-users] Any "gothcas" going from 2.65 to 3.04 I should know about?

by libor.peltan

Hi Chris, first of all, you seem to be talking about Knot DNS, so it's proper to switch to correct mailing list, instead of Knot Resolver's one. I assume you have read all the single-version migration guides below https://www.knot-dns.cz/docs/3.0/singlehtml/index.html#upgrade-2-6-x-to-2-7… . It's clear that when migrating over multiple versions, you need to take care about all the notes at once. What databases exactly are you talking about? Knot DNS uses multiple databases for different purposes, e.g. journal or KASP DB. The good news is, their format does not change much, and when it does, it's usually backwards-compatible, with some exceptions. I would strongly recommend that you clone your environment, perform the migration in some "playground" setup first, and observe if everything went well; all before migration your production setup ;) Should you encounter any issues, please contact us on our mailing-list. Anyway, you might consider a multi-step migration, so that you would migrate by just one (major) version at once, like this: 2.6.5 -> 2.7.8 -> 2.8.5 -> 2.9.9 -> 3.0.5. Thanks!

Preventing changes to zone files

by Matthew Pounsett

Is there a way to configure Knot to avoid overwriting a zone file when it's doing automatic signing? I was hoping some combination of zonefile-load and journal-content would tell Knot to store its internally managed data in the journal instead of in the zone file, but I haven't found that combination. I don't see any other likely candidates in the config options, but hoping I've missed something...

Knot DNS 3.0.5 release

by Daniel Salzman

Hello Knot DNS users, CZ.NIC has released Knot DNS 3.0.5! This version primarily fixes issues relating zone journal, zone backup, and DNSSEC key handling. The most serious bug might cause malformed zone journal if 'journal-contents: all' or 'zonefile-sync: -1' is configured. Besides the fix, an additional detection of this state is introduced. So if "malformed data" error appears after the upgrade, the journal data are already broken and there is unfortunately no better way than purging the journal (e.g. knotc -f zone-purge +journal affected.zone.net.). Changelog: https://gitlab.labs.nic.cz/knot/knot-dns/raw/v3.0.5/NEWS Download: https://www.knot-dns.cz/download/ Documentation: https://www.knot-dns.cz/documentation/ Support: https://www.knot-dns.cz/support Donation: https://donations.nic.cz/donate/?project=knot-dns Regards, Daniel

Change journal-content changes to all

by André Keller

Good afternoon, in preparation for Knot 3.1, I wanted to update our template that uses zonefile-load: difference-no-serial from journal-content: changes to journal-content: all. However, it seems that we somehow have to update the existing journal. Otherwise it seems the first change to a zone after that change, will lead to the following error (running knot 3.0.4): error: [example.net.] zone event 'load' failed (semantic check) Subsequent changes seem to be applied just fine. What is the proposed strategy to change this setting? Regards André

Extended expiration of Knot DNS Packaging GPG key

by Daniel Salzman

Hello Knot DNS users, I would like to inform users of our Debian packages (https://deb.knot-dns.cz/knot and https://deb.knot-dns.cz/knot-latest) that the initial Knot DNS Packaging GPG key 8A0EFB02C84B1E9B expired on 2021-03-13. Its expiration time had already been extended to 2022-11-11 a few months ago. But still you can get a GPG error when refreshing the repository. Please update your apt.gpg file from https://deb.knot-dns.cz/knot/apt.gpg or https://deb.knot-dns.cz/knot-latest/apt.gpg. Thank you, Daniel

Old key is being used

by Thomas

Hi, we performed successfully an algorithm rollover. After changing the algorithm in the configuration file everything worked as expected. All zones have been updated to the new algorithm. When I now sign a new zone the zone is being signed with the old algorithm's key and an algorithm rollover is being triggered immediately. Is this an expected behavior? How can I avoid this? Do I have to delete the old key? Thanks a lot, Thomas

Figuring out inconsistent logging

by Matthew Pounsett

Hi! I have two Debian 10 Buster systems, both patched up current, and both running Knot 3.0.4-1~cz.nic~buster1 from the apt repository at https://deb.knot-dns.cz/knot-latest/. Both Knot installations have virtually identical configs .. really only different in the related hosts and zone lists. Their logging configs are both: log: - target: syslog any: info One of these Knot instances logs to syslog, and the other logs to systemd-journald. I'm trying to figure out why the difference, and I've come up empty. The Knot docs simply say that if Knot is compiled against systemd, then a 'syslog' setting will use systemd-journald. Mostly I want to know so that I can convince the one using journald to stop doing that. :) What other things might trigger Knot to use syslog on a systemd-managed host?

by Thomas E.

Hi, is it possible to have two different DNSSEC policies in place? For example having one domain singed with Alg 8 and another one with Alg 13? Thanks a lot, Thomas

Dynamic update for dnskey

by Ulrich Wisser

Hi! Today we tried to do a dynamic update to the dnskey set. What we want to do is to import the ZSK from another signer. Didn’t work so well. Feb 16 17:15:28 ip-172-31-38-41 knotd[24222]: warning: DDNS, refusing to update DNSSEC-related record I guess knot doesn’t like dynamic DNSSEC updates. I even tried with policy manual:on. What does one have to do to be allowed to add (or delete) DNSKEY records? /Ulrich
