Its been over 20 years of installing, troubleshooting, training and writing and I still think the biggest issue in IT is the technician’s working knowledge of their everyday tools. It doesn’t matter if it’s a physical tool like a cable tester or software, you should not only be familiar with it, but with any changes with upgrades.
In this case I chose Wireshark and wanted to show you how display filters affect IO graphs. As I mentioned in the video, this can be ‘bad’ or ‘good’. Which one depends if you know about this new ‘feature’ or not.
I always suggest you ‘use your favorite tools on a regular basis so you can spot some of these changes when they appear so you aren’t caught off guard when you are in the middle of troubleshooting.
