Cool tool: [WayBack] GitHub – gamelinux/passivedns: A network sniffer that logs all DNS server replies for use in a passive DNS setup via [WayBack] How to log all my DNS queries? – Unix & Linux Stack Exchange (thanks mxmlnkn!).
It listens on port 53 for DNS requests then logs them to a file on regular intervals aggregating similar requests.
Usage is simple:

It sounds long ago, but this post is still so relevant for anyone not yet bringing operations and development close together. And for those who did:
[WayBack] Nick Craver – Stack Overflow: How We Do Deployment – 2016 Edition
The relevance is why Nick repeated it in 2018 in a response to a @ThePracticalDev discussion right after the first Falcon Heavy deployment, and why I repeat it now.

Still a very insightful read: [WayBack] Swap and Memory Pressure: How Developers think to how Operations people think – The Isoblog.
I totally agree with the view Kristian Köhntopp presents which I usually call “fail early, fail hard, fail clearly”.

A long time ago, I named a tool Cerberus after the mythical multi-headed dog that guards the gates of the Underworld, as it was to inspect client systems configurations to prevent they would enter a bad state.
Since I need a multi-headed tool later on, below are some links on multi-headed (Polycephaly – Wikipedia) creatures to give me inspiration.
Some of them are centered around war, others around hell, are dragons or monsters, and a few are guardians. Later I will try to put a classification in a table or so.
The idea is to replace my current Apache TLS offloading (that uses letsencrypt/certbot for the certificates) with something else like an nginx one, and maybe even make the internal part TLS too (so it becomes TLS upstreaming) so these will come in useful too:
Instead of nginx, HAproxy might be a an option too, especially as it understands TCP traffic other than http much better than nginx:
This means I should first look into nginx vs haproxy – Google Search, for instance these posts:

Since I will likely need something like this one day: [WayBack] GitHub – Nike-Inc/gimme-aws-creds: A CLI that utilizes Okta IdP via SAML to acquire temporary AWS credentials
I think I got this via Kristian Köhntopp a while ago.
