With ssh, after issuing the shutdown, you have to also issue an exit, or the shutdown, might lock your session.<br />
Usually root login might not be allowed, the use of a Setuid script or sudo shutdown now ;exit might be a way to go.

There shouldn't be a hang - the ssh call will run the command and exit as soon as it finishes.<br />

It can be a problem if you log onto the remote server and issue the &quot;shutdown now&quot; command manually. &nbsp;In that case, you could issue the command<br />
&nbsp; &nbsp; exec shutdown now<br />
so that the session ends as soon as the command completes (and before the machine shuts down).
