Whatever it is, you don&#8217;t have much info to work with, but you do have a hardware address. Sadly, VMware doesn&#8217;t seem to have an easy [...]]]></description>

In an effort to improve boot time, system performance and ease scripted configuration, ubuntu has implemented upstart, an event-based replacement for the traditional init daemon.

Additionally, we need to include the nc command string.  This is so that ssh can pass data through to the host after the command has been run.  Finally, I have redirected stdout for VPNC to stderr so that it is printed to the terminal while being used as a ProxyCommand.]]></description>
