15 systemd-networkd-wait-online is a oneshot system service (see
16 systemd.service(5)), that waits for the network to be configured. By
17 default, it will wait for all links it is aware of and which are
18 managed by systemd-networkd.service(8) to be fully configured or
19 failed, and for at least one link to be online. Here, online means that
20 the link's operational state is equal or higher than "degraded". The
21 threshold can be configured by --operational-state= option.
22
24 The following options are understood:
25
26 -i INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]],
27 --interface=INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]]
28 Network interface to wait for before deciding if the system is
29 online. This is useful when a system has several interfaces which
30 will be configured, but a particular one is necessary to access
31 some network resources. When used, all other interfaces are
32 ignored. This option may be used more than once to wait for
33 multiple network interfaces. When this option is specified multiple
34 times, then systemd-networkd-wait-online waits for all specified
35 interfaces to be online. Optionally, required minimum and maximum
36 operational states can be specified after a colon ":". Please see
37 networkctl(1) for possible operational states. If the operational
38 state is not specified here, then the value from RequiredForOnline=
39 in the corresponding .network file is used if present, and
40 "degraded" otherwise.
41
42 --ignore=INTERFACE
43 Network interfaces to be ignored when deciding if the system is
44 online. By default, only the loopback interface is ignored. This
45 option may be used more than once to ignore multiple network
46 interfaces.
47
48 -o MIN_OPERSTATE[:MAX_OPERSTATE],
49 --operational-state=MIN_OPERSTATE[:MAX_OPERSTATE]
50 Takes a minimum operational state and an optional maximum
51 operational state. Please see networkctl(1) for possible
52 operational states. If set, the specified value overrides
53 RequiredForOnline= settings in .network files. But this does not
54 override operational states specified in --interface= option.
55
56 -4, --ipv4
57 Waiting for an IPv4 address of each network interface to be
58 configured. If this option is specified with --any, then
59 systemd-networkd-wait-online exits with success when at least one
60 interface becomes online and has an IPv4 address. If the required
61 minimum operational state is below "routable", then each link (or
62 at least one link with --any) must have an IPv4 link-local or
63 routable address. If the required minimum operational state is
64 "routable", then each link must have an IPv4 routable address.
65
66 If neither --ipv4 nor --ipv6 is specified, then the value from
67 RequiredFamilyForOnline= in the corresponding .network file is used
68 if present.
69
70 -6, --ipv6
71 Waiting for an IPv6 address of each network interface to be
72 configured. If this option is specified with --any, then
73 systemd-networkd-wait-online exits with success when at least one
74 interface becomes online and has an IPv6 address. If the required
75 minimum operational state is below "routable", then each link (or
76 at least one link with --any) must have an IPv6 link-local or
77 routable address. If the required minimum operational state is
78 "routable", then each link must have an IPv6 routable address.
79
80 If neither --ipv4 nor --ipv6 is specified, then the value from
81 RequiredFamilyForOnline= in the corresponding .network file is used
82 if present.
83
84 --any
85 Even if several interfaces are in configuring state,
86 systemd-networkd-wait-online exits with success when at least one
87 interface becomes online. When this option is specified with
88 --interface=, then systemd-networkd-wait-online waits for one of
89 the specified interfaces to be online. This option is useful when
90 some interfaces may not have carrier on boot.
91
92 --timeout=SECS
93 Fail the service if the network is not online by the time the
94 timeout elapses. A timeout of 0 disables the timeout. Defaults to
95 120 seconds.
96
97 -q, --quiet
98 Suppress log messages.
99
100 -h, --help
101 Print a short help text and exit.
102
103 --version
104 Print a short version string and exit.
