I always get requests to demonstrate everyday things that I do that may help you out.
If you ‘use’ your various tools, you are bound to develop skills and techniques that can not be taught in a classroom or in a YouTube video.
In this example, I noticed the network was a bit ‘laggy’ and simply started a Wireshark capture, and a conversation between my NVR and my camera filled my screen. This is very odd when you realize that I did not have a span port or tap in use.
When I took a closer look at the [packets, I noticed that the delta time was less than 1 ms, which would mathematically result in 1000 packets per second.
Since all the packets were unique, I knew this was NOT a loop of any kind, but why was this conversation getting flooded across my network.
In the video, you see that I verified that the Mac address the NVR was using was the camera’s Wi-Fi MAC but oddly enough the camera was still responding to the NVR using the wifi mac even though it was using the wired connection.
I show you the odd Wireshark trick, so enjoy, and don’t be afraid to capture a few packets.
FYI. went dyslexic with the Mac address at one point. I’m sure you will out where.
