<p class="MsoNormal">I think he's balking at even having netcat installed on the system. My opinion is that if you have someone with enough access to the system to run nc in that manner then you have bigger problems. And if it's a legitimate user doing it without
understanding the problem, you still have bigger problems.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Right that's understandable but that's NOT what I'm doing with netcat.<br>
I'm using netcat to SEND, not receive. The receiving program is a full<br>
program that does only one function not a random netcat listening on a<br>
port. The daemon that I want to give the ability to send notifications<br>
to other clients has its output formatted and sent via netcat to those<br>
clients:<br>
<br>
$ daemon.program | notifier.processing.script &<br>
<br>
#notifier script:<br>
if ( input == some.condition )<br>
cat condition.message.file | netcat remote.client notification.port<br>
fi<br>
<br>
There's no listener here at all with netcat.<br>
