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.
