NAME
       networkd-dispatcher - Dispatcher service for systemd-networkd
       connection status changes

SYNOPSIS
       networkd-dispatcher [-h] [-S SCRIPT_DIR] [-T] [-v] [-q]

DESCRIPTION
       Dispatcher daemon for systemd-networkd connection status changes. This
       daemon is similar to NetworkManager-dispatcher, but is much more
       limited in the types of events it supports due to the limited nature of
       systemd-networkd(8).

       Desired actions (scripts) are placed into directories that reflect
       systemd-networkd operational states under SCRIPT_DIR and are executed
       when the daemon receives the relevant event from systemd-networkd.

       The deamon listens for signals from systemd-networkd over dbus, so it
       should be very light on resources (e.g. no polling). It is meant to be
       run as a system-wide daemon (as root). This allows it to be used for
       tasks such as starting a VPN after a connection is established.

OPTIONS
       -h, --help
           Print command-line syntax and program options to stdout.

       -S, --script-dir=SCRIPT_DIR
           Location under which to look for scripts. Like the PATH environment
           variable, this may contain multiple directories separated by : and
           in case multiple directories have scripts with the same name, the
           earliest directory wins. Defaults to
           /etc/networkd-dispatcher:/usr/lib/networkd-dispatcher.

       -T, --run-startup-triggers
           Generate events reflecting preexisting state and behavior on
           startup. This can be used to ensure that triggers are belatedly run
           even if networkd-dispatcher is invoked after systemd-networkd has
           already started an interface.

       -v, --verbose
           Increase verbosity by one level. The default level is WARNING. Each
           use of -v will increment the log level (towards INFO or DEBUG), and
           each use of -q will decrement it (towards ERROR or CRITICAL).

       -q, --quiet
           Decrease verbosity by one level.

CONFIGURATION FILES
       The systemd service reads /etc/default/networkd-dispatcher as an
       environment file for additional daemon arguments.

       The scripts to be run on network changes are in subdirectories
       routable.d/, dormant.d/, no-carrier.d/, off.d/ inside SCRIPT_DIR. The
       default value for SCRIPT_DIR is
       /etc/networkd-dispatcher:/usr/lib/networkd-dispatcher.
