Mastodon

Welcome to Larvitz Blog! I’m Christian, a Senior Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.

Have a question or want to discuss something? Find me on the Fediverse at @Larvitz@burningboard.net. I’m always happy to chat!

Hardware Keys Without GnuPG: The Rust OpenPGP Card Stack, Now in FreeBSD Ports

Three small Rust tools from the OpenPGP Card project replace the GnuPG stack for my everyday hardware key work: oct to manage OpenPGP cards and Nitrokeys, oct-git to sign Git commits, and openpgp-card-ssh-agent as a hardware-backed SSH agent. I ported all three to FreeBSD and they are now in the ports tree. This article explains what each tool does, how they share PIN handling, and how I set them up on Fedora and on my FreeBSD T480.
