Hello. In case you're using our upstream repositories for Debian or Ubuntu, as suggested on https://www.knot-resolver.cz/download/ you'll be running into their signing key expiring since today. As we didn't update it in time, you'll have to update it manually by re-running: wgethttps://secure.nic.cz/files/knot-resolver/knot-resolver-release.deb dpkg -i knot-resolver-release.deb Ticket: https://gitlab.nic.cz/knot/knot-resolver/-/issues/747 We also forgot to add Ubuntu 22.04, so that is fixed now, too. --Vladimir

Re: KNOT sharing cache or not for different instances (nat64 vs no nat64)

In that case I expect you'll need to stay on 5.x for now, with separate processes for dns64 and non-dns64 (but they can share the cache). Overall I don't think the current code can support multiple certificates.

That is possible, but with 5.x I probably wouldn't recommend it, as it's been left out of documentation (by mistake) and overall I don't have much trust in that part of 5.x policies. But after you migrate to >= 6.x, I would recommend just having a single shared configuration. And in views you can select dst-subnet paired with dns64 options. Such deployments were taken into account when designing 6.x views. https://www.knot-resolver.cz/documentation/latest/config-views.html#config-… In 6.x it would probably also be harder for you to run multiple configurations at once on a single machine, so that's another reason to unify this when you migrate. --Vladimir

I believe there is neither effort to disallow them nor to make them work. Off the top of my head I'm not sure how it will be in practice; you could just try. Either way, please don't use them.

Dear Knot Resolver users, Knot Resolver version 5.7.3 (stable) has been released! This maintenance update brings a minor improvement to stats and a bugfix to missing NSEC3 records. An early-access version 6.0.8 including these changes and more will come at a later date - a few more things need to be finalized there before release. Improvements: - stats: add separate metrics for IPv6 and IPv4 (!1544) Bugfixes: - fix NSEC3 records missing in answer for positive wildcard expansion with the NSEC3 having over-limit iteration count (#910, !1550) Full changelog: https://gitlab.nic.cz/knot/knot-resolver/raw/v5.7.3/NEWS Sources: https://secure.nic.cz/files/knot-resolver/knot-resolver-5.7.3.tar.xz GPG signature: https://secure.nic.cz/files/knot-resolver/knot-resolver-5.7.3.tar.xz.asc Documentation: https://www.knot-resolver.cz/documentation/v5.7.3/ -- Oto Šťáva | Knot Resolver team lead | CZ.NIC z.s.p.o.

I'm not aware of RFCs saying that resolvers should fail in such situations. My understanding is more like it's allowed not to work. Anyway, it would be better to continue this thread on knot-resolver-users(a)lists.nic.cz (I already have posted there about this a couple days ago.) --Vladimir
