@jpmens For instance, the entire Internet infrastructure is managed with curl: https://labs.ripe.net/author/ed_shryane/using-api-keys-in-the-ripe-database/

@jpmens And when there is a security issue in curl, the mainstream media headlines are "A Bug In A Program You've Never Heard About Threatens The Entire Internet"

Les sièges au FOSDEM sont conçus pour des étudiant·es minces, jeunes et en bonne forme physique. Les professionnels un peu plus âgés et plus lourds ont mal au bas du dos après quelques heures de devroom.

The mess of programming. An official API for name resolution with full details (DNSQuery_A) works for HTTPS records in Windows 11 but does not work working in WIndows 10.

"Is big DNS taking over?" by Farzaneh Badiei (Digital Medusa)

Will the big US-based public #DNS resolvers replace everything?

Preliminary report at https://digitalmedusa.org/wp-content/uploads/2023/12/Upload-DNS-Resolvers-First-Draft-October.pdf

#FOSDEM

In many countries (like France…) these public #DNS resolvers are useful for freedom (access to censored content because of the increased demand of governments for DNS-based blocking).

#FOSDEM

"rDNS Map In Your Hands" by Alexey Milovidov It produces this: https://reversedns.space/ (by requesting every PTR for IPv4 space)

https://mastodon.gougere.fr/@DNSresolver/113929400664745720 (PTR records are for traceroute and broken email servers)

"The entire picture is four gigapixels. Not all viewers can display it."

#FOSDEM

"Yes, I can do it for IPv6, with some tricks."

#FOSDEM

The good thing about getaddrinfo: it works and on all platforms.

The bad things: not the full response details like the TTL (remember it is not just for #DNS), no way to control resolution from the application (some may say it is a good thing)

And it is only for A/AAAA records. How to use SVCB?

But also, Firefox (the speaker works for Mozilla) has a DoH client, DoH being easier / better than getaddrinfo for a Web browser.

@jpmens "Then a simple SQL query"

@lanodan I manage my multiple accounts with fetchmail and download everything in the same mailboxes. And 'set reverse_name=yes' in mutt for using the right address when replying.

@lanodan When I need IMAP, I use fetchmail to fetch the mail and then use mutt on the retrieved mailboxes.

So, to move away from tabs vs. spaces, emacs vs. vi or rust vs. go, what about a thread mutt vs. aerc?

#FOSDEM

A BIND maintainer comes into the room.

"Sorry it is full. But you can come in."

#FOSDEM

"I don't understand why #DNSSEC is not yet the default for resolvers on Linux machines."

#FOSDEM

"Setting up an email server requires to add around 15 #DNS records."

#FOSDEM

Very good talk about the synchronization of the all-in-one email server with #DNS: no standard, many custom APIs.

Solution; a dedicated proxy, dnsclay (receives DNS dyn. update from mox and talks many custom APIs).

Valentin Gosu @valenting on name resolution "This talk may incluse some rants"

getaddrinfo was invented in 1995…

#FOSDEM

#DNS devroom at #FOSDEM. Already almost full.

"getaddrinfo sucks, everything else is much worse"
