netctl.special - Special netctl systemd units
netctl.service, netctl-auto.service, netctl-ifplugd.service,
Bundled with netctl come a few systemd units that are not controlled
through the netctl command. They can be used through the systemctl
utility of systemd.
When started, this unit tries to start the profiles that were
running when the unit was last stopped. In some cases, the interface
a profile binds to might not be available yet, when 'netctl.service'
tries to bring a profile up. A simple, hackish, solution is to do:
echo "[[ -t 0 ]] || sleep 3" > /etc/netctl/interfaces/<interface>
chmod 755 /etc/netctl/interfaces/<interface>
A more concise solution is to first enable a profile through netctl
and then disable it again through systemctl:
netctl enable <profile>
systemctl disable netctl@<profile>
This way the unit configuration file for the profile remains in
existence, while the profile is not enabled.
When enabled, this unit stores and stops the active network profiles
before the machine is put to sleep. After the system is resumed,
previously stored profiles are restarted.
This unit issues a scan on the interface it is used for and tries to
start a profile for a network it finds. It is targeted at wireless
interfaces. Profile specific values for 'WPADriver' are ignored, but
it is possible to specify 'WPADriver=' in an interface hook
('/etc/netctl/interfaces/<interface>'). +
Use *netctl-auto*(1) instead of *netctl(1)* to control the automatic
profile selection when using this unit.
This unit starts ifplugd on the interface it is used for. It will
try to start a netctl profile whenever a cable is plugged into the
interface and stop the profile when the cable is unplugged. Note
that this unit does not provide ''.
When activated, this unit waits for all enabled netctl profiles to
come online. Enabling this unit causes '' to
only be reached once all enabled netctl profiles are fully
connected. The maximum time, in seconds, to wait for profiles can be
passed to this unit via 'TIMEOUT_ONLINE='. The default value is
+120+. If a timeout occurs, the service enters a failed state.
