<title>Description</title>
|
|
|
|
<para><command>systemd-networkd-wait-online</command> is a
|
|
oneshot system service (see <citerefentry><refentrytitle>systemd.service</refentrytitle><manvolnum>5</manvolnum></citerefentry>), that waits for the network to be
|
|
configured. By default, it will wait for all links it is aware of
|
|
and which are managed by
|
|
<citerefentry><refentrytitle>systemd-networkd.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
to be fully configured or failed, and for at least one link to be online. Here, online means that
|
|
the link's operational state is equal or higher than <literal>degraded</literal>. The threshold
|
|
can be configured by <option>--operational-state=</option> option.</para>

<listitem><para>Network interface to wait for before deciding if the system is online. This

is useful when a system has several interfaces which will be configured, but a particular

one is necessary to access some network resources. When used, all other interfaces are ignored.
|
|
This option may be used more than once to wait for multiple network interfaces. When this
|
|
option is specified multiple times, then <command>systemd-networkd-wait-online</command> waits
|
|
for all specified interfaces to be online. Optionally, required minimum operational state can be
|
|
specified after a colon <literal>:</literal>. Please see
|

<citerefentry><refentrytitle>networkctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
|
for possible operational states. If the operational state is not specified here, then

the value from <varname>RequiredForOnline=</varname> in the corresponding
