systemd-networkd-wait-online.service, systemd-networkd-wait-online - Wait for network to come 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
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
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
waits for all specified interfaces to be online. Optionally, required minimum and maximum operational states can be specified after a colon
":". Please see
for possible operational states. If the operational state is not specified here, then the value from
in the corresponding
file is used if present, and
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
for possible operational states. If set, the specified value overrides
files. But this does not override operational states specified in
Even if several interfaces are in configuring state,
exits with success when at least one interface becomes online. When this option is specified with
waits for one of the specified interfaces to be online. This option is useful when some interfaces may not have carrier on boot.
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.
