8. YEARS. OLD. And STILL relevant. Messer's videos are the ONLY tech knowledge videos I would view and trust after so much time. Thanks, Professor. Never stop doing what you're doing!

[@raduiulia4034]

I just LOVE your videos! Good job!

[@LastHumansGarage]

I wish you had smaller playlists for each section 1 thru 6 instead of 2 gigantic playlists (184 videos and 73 videos.) it gets pretty confusing trying to remember which video you left off on.

Did you know your name translates to "Professor Knife" in German? Sounds like a dope Rapper Name, if you ask me!

Is it possible someone tip in the cable and ride on an already authenticated port connection to spoof ?

[@professormesser]

Most connections these days will be encrypted, so tapping the line or grabbing the packets isn't going to help much.

[@ibanez33150]

is the authenticator a switch device?
