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.
