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>

		<description><![CDATA[Ping is an extremely useful utility for troubleshooting network connectivity.  However, on today&#8217;s networks, pings are often discarded.
