NAME

       systemd-networkd-wait-online.service, systemd-networkd-wait-online@.service, systemd-
       networkd-wait-online - Wait for network to come online

SYNOPSIS

       systemd-networkd-wait-online.service

       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.

       The service systemd-networkd-wait-online.service invokes systemd-networkd-wait-online
       without any options. Thus, it waits for all managed interfaces to be configured or failed,
       and for at least one to be online.

       The service systemd-networkd-wait-online@.service takes an interface name, and invokes
       systemd-networkd-wait-online with -i and the specified interface name. Thus, wait for the
       specified interface to be configured and online. For example,
       systemd-networkd-wait-online@eth0.service waits for eth0 to be configured by
       systemd-networkd and online.

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. If the required minimum
           operational state is below "routable", then each link (or at least one link with
           --any) must have an IPv4 link-local or routable address. If the required minimum
           operational state is "routable", then each link must have an IPv4 routable address.

           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. If the required minimum
           operational state is below "routable", then each link (or at least one link with
           --any) must have an IPv6 link-local or routable address. If the required minimum
           operational state is "routable", then each link must have an IPv6 routable address.

           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.
