DNS‑петля: как сервер смотрит сам в себя и не находит выхода

Доменные имена не резолвятся, страницы висят, а по IP всё доступно. В логах DNS‑сервера при этом чисто, BIND запущен, конфигурация на первый взгляд выглядит рабочей. Разбираемся, как одна ошибка в forwarders может отправить DNS‑запросы по кругу и превратить обычный резолвинг в цепочку таймаутов.

I did a thing.
https://github.com/coredns/coredns/releases/tag/v1.14.4
#coredns 1.14.4 Forward-plugin supports new `next_on_nodata` directive
When one upstream returns a NODATA response, it‘ll then try the next forward plugin, instead of responding with NODATA itself.

Celebrating #DigitalIndependenceDay with a foundational one: #DNS.

Every lookup travels unencrypted by default. Third-party #DoT​/​#DoH resolvers add encryption but shift trust elsewhere.

I run a self-hosted #CoreDNS resolver, handling this locally. Its plugin system enables #AdBlocking and delegation to upstreams like #PKDNS, which resolves names from the Mainline #DHT, offering self-sovereign, censorship-resistant #DNS.

Done.

https://github.com/coredns/coredns/pull/8065

You have an authoritative #DNS server locally, and want to overwrite _some_ but not _all_ records? There you go. #CoreDNS 1.14.3 with this patch applied allows you to do exactly that.

Setup

*CoreDNS* Corefile:
. {
forward . RECURSOR {
next NOERROR
}
forward . UPSTREAM
}

*Recursor*, e.g. PDNS Recursor, with forward-zones-file content (or YAML equivalent):
+.=BIND9-IP

#CoreDns deprecated the "alternate"-plugin apparently - and I've relied on a patch I've made years ago to treat empty NOERROR-responses (colloquially known as NODATA) as errors, allowing for some naughty DNS hijacking.

Ported that code from years back to the in-tree "forward"-plugin. Going to verify that it works and propose the patch upstream. Hope it gets picked up this time.

Ok. This the moment I stop using #coredns and maybe #powerdns, for #erldns. 😎

The implement of #CodDel without me doing a single thing... Simply start the server... I don't think I need another dns authoritative server. 😉

Excellent work from #dnsimple!

Today:

- There was an internet outage for about 5 hours.
- After which my home server froze (first Linux crash I've seen in a while).
- After force restarting it, somehow the Docker container networks changed so they broke one of my views for split-horizon DNS in #CoreDNS, which took about 2 hours to debug.

Breath in... breath out... breath in...
