<a name="description"></a><h2>Description</h2>
<p><span class="command"><strong>nm-online</strong></span> is a utility to find out whether we are
online. It is done by asking NetworkManager about its status. When run,
<span class="command"><strong>nm-online</strong></span> 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).</p>
<p>By default NetworkManager waits for IPv4 dynamic addressing to complete
but does not wait for the <code class="literal">auto</code> IPv6 dynamic addressing. To
wait for IPv6 addressing to complete, either (1) change the network
connection's IPv6 <code class="literal">may-fail</code> setting to <code class="literal">no</code>,
and/or (2) change the IPv6 addressing method to <code class="literal">manual</code> or
<code class="literal">dhcp</code>, to indicate that IPv6 connectivity is expected.</p>

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,
<span class="command"><strong>nm-online -s</strong></span> will just return immediately, regardless of the
current network state.)</p></td>
