firewall-applet

firewall-applet is a tray applet for firewalld. It provides information about the firewalld configuration like the default zone and also the zone bindings like connections, interfaces and sources.

There is a left and also right mouse button menu and also a tooltip with the active settings when moving the mouse over the icon.

The applet has ben ported over to Qt4 as the StatusIcon support in Gtk3 has been deprecated.

Limitations with Gnome3

Not all options are available in Gnome3. This desktop environment changes the behaviour of the applet externally:

  • With enabled notifications, the icon is made unvisible after it was sending out a notification. The applet is not able to detect or change that it is hidden.
  • The tooltip is not visible.
  • The menus are not always usable or visible.
