NAME

       nm-online - ask NetworkManager whether the network is connected

SYNOPSIS

       nm-online [OPTIONS...]

DESCRIPTION

       nm-online is a utility to find out whether we are online. It is done by asking
       NetworkManager about its status. When run, nm-online waits until NetworkManager reports an
       active connection, or specified timeout expires. On exit, the returned status code should
       be checked (see the return codes below).

       By default NetworkManager waits for IPv4 dynamic addressing to complete but does not wait
       for the auto IPv6 dynamic addressing. To wait for IPv6 addressing to complete, either (1)
       change the network connection's IPv6 may-fail setting to no, and/or (2) change the IPv6
       addressing method to manual or dhcp, to indicate that IPv6 connectivity is expected.

OPTIONS

       -t | --timeout seconds
           Time to wait for a connection, in seconds. If the option is not provided, the default
           timeout is 30 seconds.

       -x | --exit
           Exit immediately if NetworkManager is not running or connecting.

       -q | --quiet
           Don't print anything.

       -s | --wait-for-startup
           Wait for NetworkManager startup to complete, rather than waiting for network
           connectivity specifically. Startup is considered complete once NetworkManager has
           activated (or attempted to activate) every auto-activate connection which is available
           given the current network state. (This is generally only useful at boot time; after
           startup has completed, nm-online -s will just return immediately, regardless of the
           current network state.)

EXIT STATUS

       nm-online exits with status 0 if it succeeds, a value greater than 0 is returned if an
       error occurs.

       0
           Success – already online or connection established within given timeout.

       1
           Offline or not online within given timeout.

       2
           Unknown or unspecified error.
