Features & Utilities

Beyond application installation and system setup, Linutil includes categories for security hardening, gaming, and a wide range of system utilities.

Security

Apply firewall baselines to protect your Linux system. Based on CTT’s recommended security rules — for more detail see christitus.com/linux-security-mistakes.

UFW Firewall Baselines

UFW (Uncomplicated Firewall) is a user-friendly frontend for iptables. This script:

  • Installs UFW if not present
  • Applies CTT’s recommended baseline rules for IPv4 and IPv6
  • Enables the firewall
# Check UFW status after running the script
sudo ufw status verbose

FirewallD Baselines

An alternative to UFW, FirewallD is the default firewall manager on Fedora and RHEL-based systems. This script configures FirewallD with CTT’s recommended rules.

Gaming

Gaming Dependencies

Installs the libraries and tools needed to run games on Linux across different distributions, such as Wine, Vulkan support, MangoHud, GameMode, and related runtime dependencies. Steam and Lutris are managed separately from the Game Launchers section.

Proton Compatibility Tools

The Gaming tab includes ProtonPlus and ProtonUp-Qt under Tools and Setups. Both entries use an interactive Install, Uninstall, or Abort prompt, try native packages first, and fall back to Flathub Flatpak packages:

ToolFlatpak ID
ProtonPluscom.vysp3r.ProtonPlus
ProtonUp-Qtnet.davidotek.pupgui2

Game Launchers

The Gaming tab includes a Game Launchers section for managing common launchers with an interactive Install, Uninstall, or Abort prompt.

LauncherBehavior
SteamUses native packages on Arch-based systems; uses Flatpak on several other distros where native availability is less consistent
LutrisUses the native package manager on supported distros
RetroArchUses native packages where available, with Flatpak fallback for selected distros
HeroicUses Flatpak on non-Arch systems; on Arch-based systems builds heroic-games-launcher-bin directly from AUR

On NixOS, these entries print declarative configuration guidance instead of modifying the system imperatively.
