Speed is to fast. Need time to locate what/where you are having us look. It is one thing for two experienced people to move that fast, but you are teaching this to mostly new to NMAP and especially WireShark. Since WireShark needs a lot of scrolling and is used in a virtual environment while watching along, it sometimes needs the cursors to be reposition. It would be nice if the pace was a little slower in the demonstrations, especially if you want us to do it at the same time. Lot of pausing and rewinding. Last note is the downloadable file didn't fully match your demonstration as some fields showed differently then what yours read.

Instructor Bio
I love packet analysis!
Why? Because packets hold the keys to solving gritty, complex, long-standing issues affecting networks and applications today. However, it is one thing to capture packets and another to interpret and understand them.
I am passionate about helping network engineers, cybersecurity professionals, and developers of all experience levels gain comfort with packet analysis. I bring 20 years of packet analysis experience to each course that I teach, whether live or on-demand. Join me on a course and let's have some fun while we learn!
