Synopsis

systemd-networkd-wait-online.service

/usr/lib/systemd/systemd-networkd-wait-online

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.

Options

The following options are understood:

-i INTERFACE[:OPERSTATE], --interface=INTERFACE[: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 operational state 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 OPERSTATE, --operational-state=OPERSTATE

Takes an 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.

--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.
