FOSS Linux

On my bench, one nmap service scan and one hydra burst against an isolated Kali Purple defender produced 2009358 and 2001219 alerts inside twenty seconds. This hands-on lab covers the VMware host-only setup, Suricata rules and HOME_NET tuning, both attacks, a field-by-field reading of fast.log and eve.json, and the ladder for a silent sensor.

Three live distros, three package databases, one question: which installed apps still link GTK3? This audit runs apt, dnf and pacman reverse-dependency sweeps plus ldd proof on Mint 22.3, Fedora 44 and CachyOS, then sorts 15 apps into GTK3 holdouts, GTK4 movers and toolkit outsiders, with snap and flatpak runtime caveats and per-audience recommendations.

Ubuntu 26.04 LTS ships fzf seven releases behind upstream, while Arch Linux sat at the newest tag on the same day. This date-stamped audit gives you the exact read-only commands to check package version lag on apt, dnf5, and pacman, then ranks every fix from doing nothing at all to switching distributions.

Neofetch was archived in April 2024 with its final release dating to 2020, so this guide puts fastfetch through a real workout. I install it on Ubuntu, Fedora, and Arch, benchmark both tools on the same machine, and walk through JSONC configuration, the Media and Player modules, and animated terminal logos.

Tributary is a pure-Rust GTK4 music player built around the classic Rhythmbox library view, with modern remote backends for Subsonic, Jellyfin, Plex and DAAP. I tested version 0.7.2 on Mint, Fedora and CachyOS: native install paths, the Flathub-absent Flatpak route, the preview-first Rhythmbox import, and the alpha limits worth knowing before you switch.
