online - Wait for network to come online
Синопсис (Synopsis)
systemd-networkd-wait-online.service
/usr/lib/systemd/systemd-networkd-wait-online
Описание (Description)
systemd-networkd-wait-online
is a oneshot system service (see
systemd.service(5)), 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 systemd-networkd.service(8) 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
"degraded". The threshold can be configured by
--operational-state=
option.
Параметры (Options)
The following options are understood:
-i
INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]],
--interface=
INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]]
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
systemd-networkd-wait-online
waits for all specified
interfaces to be online. Optionally, required minimum and
maximum operational states can be specified after a colon
":". Please see networkctl(1) for possible operational
states. If the operational state is not specified here, then
the value from RequiredForOnline= in the corresponding
.network file is used if present, and "degraded" otherwise.
--ignore=
INTERFACE
Network interfaces to be ignored when deciding if the system
is online. By default, only the loopback interface is
ignored. This option may be used more than once to ignore
multiple network interfaces.
-o
MIN_OPERSTATE[:MAX_OPERSTATE],
--operational-state=
MIN_OPERSTATE[:MAX_OPERSTATE]
Takes a minimum operational state and an optional maximum
operational state. Please see networkctl(1) for possible
operational states. If set, the specified value overrides
RequiredForOnline= settings in .network files. But this does
not override operational states specified in --interface=
option.
-4
, --ipv4
Waiting for an IPv4 address of each network interface to be
configured. If this option is specified with --any
, then
systemd-networkd-wait-online
exits with success when at least
one interface becomes online and has an IPv4 address. The
option is applied only for the operational state "degraded"
or above. If neither --ipv4
nor --ipv6
is specified, then the
value from RequiredFamilyForOnline= in the corresponding
.network file is used if present.
-6
, --ipv6
Waiting for an IPv6 address of each network interface to be
configured. If this option is specified with --any
, then
systemd-networkd-wait-online
exits with success when at least
one interface becomes online and has an IPv6 address. The
option is applied only for the operational state "degraded"
or above. If neither --ipv4
nor --ipv6
is specified, then the
value from RequiredFamilyForOnline= in the corresponding
.network file is used if present.
--any
Even if several interfaces are in configuring state,
systemd-networkd-wait-online
exits with success when at least
one interface becomes online. When this option is specified
with --interface=
, then systemd-networkd-wait-online
waits
for one of the specified interfaces to be online. This option
is useful when some interfaces may not have carrier on boot.
--timeout=
SECS
Fail the service if the network is not online by the time the
timeout elapses. A timeout of 0 disables the timeout.
Defaults to 120 seconds.
-q
, --quiet
Suppress log messages.
-h
, --help
Print a short help text and exit.
--version
Print a short version string and exit.
