Sometimes I am just a hat rack.

A while back we got fibre to the home, converting from old DSL technology which worked well enough for our needs.

And, yes Gens A thru Z, this boomer had a landline. And of course connected to a phone on the landline RJ11 was a DSL filter.

For nearly 2 years I had heard a hum on that phone. Dutifully saw the filter and ignored it. Figuring there was ground in the house somewhere.

This evening, while dusting, the WTAF moment hit me.

Removed the filter. No Noise

As the kids say #NoFilter

@kistel maintains #Netiscope. Not to be confused with Netskope. 😁

It's a small #OpenSource tool for checking network connectivity from the #CLI or through an optional local #GUI. It runs checks for local interfaces, #DNS resolvers, open resolvers, root DNS servers, port filtering, #DoH, #SSH host keys and #IPv6 path MTU.

Doing some prep for next week and I'm kicking myself for not noticing what was going on here for the longest time:

Find the largest prime factor of 3^15 + 3^11 + 3^6 + 1

Razvan Dimescu is building something very interesting with #Numa, a portable #DNS resolver in a single #Rust binary that supports oblivious DNS over HTTPS: https://numa.rs/blog/posts/odoh-anonymous-dns-without-an-account.html

#ODoH changes the trust model. The resolver should not see who is asking, and the relay should not see what is being asked. That separation is a meaningful architectural improvement over #DoH.

DoH на роутере OpenWRT, Mikrotik и Asus: пошаговая инструкция от того, кто сам хостит резолвер

Если коротко, DNS это последний открытый протокол в вашей сети, по которому провайдер (и любой джентльмен в кафе на open WiFi) видит, куда вы ходите. HTTPS закрыли, SNI потихоньку прячут через ECH, а DNS как был в плейне на 53-м порту, так в большинстве домашних сетей и остался. DoH (DNS over HTTPS) это лечит, но не на устройстве, а на роутере, чтобы один раз настроил и забыл про все смартфоны, тостеры и умные лампочки. Я три месяца пилю свой DNS-резолвер с фильтрацией и за это время насмотрелся на чужие конфиги достаточно, чтобы написать инструкцию без воды. Разберу OpenWRT, Mikrotik (RouterOS 7+) и Asus с Merlin, плюс подводные камни, в которые я лично наступил.
