This video demonstration is pertaining sniffing network packets. Not your grandma's sniffer, but a little bit with twist. The video is to demonstrate how to do it remotely. Which is a fine twist.
Watch and learn.
p.s.
I did not creat the video, so I apologize ahead of time for the video is not clear, but not too bad either. You can still make it all out what the demonstrator is doing. But it is not TV clear.
