SYSTEMD-NETWORKD-WAIT-ONLINE.SEsystemd-networkd-wait-onlinSYSTEMD-NETWORKD-WAIT-ONLINE.SERVICE(8)
NAME
systemd-networkd-wait-online.service, systemd-networkd-wait-online - Wait for network to
come online
SYNOPSIS
systemd-networkd-wait-online.service
/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[: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.
