NAME

   firewall-applet - firewalld applet

SYNOPSIS

   firewall-applet [OPTIONS...]

DESCRIPTION

   firewall-applet is a tray applet for firewalld.

OPTIONS

   firewall-applet does not support any special options.

   The following options are supported:

   -h, --help
       Prints a short help text and exists.

QSETTINGS

   firewall-applet has additional settings to adapt the look and feel.
   QSettings is used and stores them in ~/.config/firewall/applet.conf.
   The file is automatically reloaded if it has been changed and the new
   settings will immediately be effective.

   There is also the global config file /etc/firewall/applet.conf, which
   contains the default values. The settings in this file will be
   overloaded by settings in the user settings file.

   Here is an example applet.conf file:

       [General]
       notifications=true
       show-inactive=true

   The following settings are supported:

   notifications
       The applet shows notifications if enabled. This setting can be
       enabled also in the applet with the "Enable Notifications" checkbox
       in the right mouse menu.

       This setting defaults to false.

       If notifications are shown for these actions if enabled:

       *   Connection to firewalld established

       *   Connection to firewalld lost

       *   Firewall has been reloaded

       *   Default zone has been changed

       *   Panic mode has been enabled or disabled

       *   Activation, deactivation or change of zones bound to interfaces

       *   Activation, deactivation or change of zones bound to sources
           addresses

   show-inactive
       Show applet also if firewalld is not running. If firewalld has been
       stopped or is not running the applet will be hidden and not visible
       in the applet tray. Enable this setting to see the applet all the
       time for example to be sure that the firewall is active.

       This setting defaults to false.

   shields-up
       The shields-up zone name to be used if shields-up is enabled.

       This setting defaults to 'block'.

   shields-down
       The shields-down zone name to be used if shields-up has been
       deactivated again.

       This setting defaults to 'public'.

   blink
       If enabled, the applet icon blinks in these cases:

       *   Connection to firewalld lost

       *   Panic mode has been enabled or disabled

       This setting defaults to false.

   blink-count
       The number of blinks if blink is enabled.

       This setting defaults to 5.
