As an opportunity to rewire my brain from "docker" to "podman" and "buildah" I started to create an image build with an ECH enabled curl at https://gitlab.com/hoexter/ech.

If you want the latest pflogsumm release form unstable on your Debian trixie/stable mailserver you've to rely on pining (Hint for the future: Starting with apt 3.1 there is a new Include and Exclude option for your sources.list).

With TLS 1.3 more parts of the handshake got encrypted (e.g. the certificate), but sometimes it's still helpful to look at the complete handshake. curl uses the somewhat standardized env variable for the key log file called SSLKEYLOGFILE, which is also su…

I'm not hanging around on IRC a lot these days, but when I do I used hexchat (and xchat before).

exfatprogs 1.3.0 added a new defrag.exfat utility which turned out to be not reliable and cause data loss. exfatprogs 1.3.1 disabled the utility, and I followed that decision with the upload to Debian/unstable yesterday.

If someone hands you an IP:Port of a Google Cloud load balancer, and tells you to connect there with TLS, but all you receive in return is an F (and a few other bytes with none printable characters) on running openssl s_client -connect ..., you might be m…
