What’s missing in every installation of a Fedora 25 desktop?

Firewall-applet Fedora 25 LXQt

If you’re running any desktop flavor of Fedora 25, congratulations! You’re using one of the better-designed desktop Linux distributions.

However, “better-designed” does not necessarily mean that everything is in place, for in the case of Fedora 25, it certainly is not. Most important components you expect to see on a modern desktop operating system, like a firewall application, are in place. But a few are not.

Take, for example, that firewall I referenced above. It’s called FirewallD on Fedora, and the system gives you three means by which to interact with it: From the command line, from a graphical interface called firewall-config, and from an applet, aptly called firewall-applet The first two come pre-installed, but not the third.

So that’s the one application that’s missing in every installation of a Fedora 25 desktop. Destined for the system tray and designed to start on boot, firewall-applet is designed to give you an easy means to manipulate aspects of the firewall and also to launch firewall-config. If your Linux desktop is any flavor of a Fedora 25 desktop, firewall-applet should be in your system tray. It’s like what the anti-virus applications provide on Windows. And yes, it comes with notifications, though that feature is disabled by default.

So why is Firewall-applet not install by default on any desktop flavor of Fedora (25)? I don’t know, but this I know: It’s easy to install using the following command.

# Install firewall-applet

sudo dnf install firewall-applet

#

After installation, you can launch it by typing firewall-applet. Rebooting will also accomplish the same, because it’s designed to start on boot. If you check the list of startup applications, you’ll find an entry for it there.
