Chris, you are just awesome! Do you have whole your courses available somewhere? Like you mentioned you run a few days classes. I am very keen to watch those recorded - something like what INE (and others) does.

Fantastic Chris!
Your wait for the packet from layer 7 (1:12:00) was hilarious!
You have actually inspired me to learn more on TCP.
Thanks for the video.

Thanks very much,

Chris, I have learned a lot from you in this video that I have not learned in last 10 years. thanks

[JDBoelter]

I feel as if I hit the motherlode of TCP and Wireshark knowledge with this presentation. Thanks, Chris!

[parthamishra]

I hope you know you're awesome !! The best thing is how you put 'air' into explanations and let the audience take notice of subtle things, ruminate, analyze and really understand. You have covered so many topics in this single session and made sure that everyone remembers/ retains 90% of those (I'm an app-guy and others would retain more than me). Amazing stuff !!
