29:10 I spent a lot of time earlier to understand that why I am getting huge value in segment length column although MTU is set 1500. Thank you Chris for going to different tangents; it helps a lot! Thank you David for bringing such valueable persons on your channel!

[zchantzis]

David & Chris you are opening our eyes 👀. Thank you 🙏

[jjdope]

A very big thank you to both of you. You guys are literally changing the way I look into network issues and I am becoming better and better each day. Keep up the beyond-excellent work.

[Mike.Kachar]

I ❤ the videos you do with Chris Greer.
The info he provides about Wireshark & what you're looking at + for within pcap's is something, I feel, today every network'er should know how to do & what to look for.
👍👍👌

Wasn't expecting to watch this end to end, - but damn, enthralled. Love this stuff!

[TomWhi]

Ironically talking about the slow passage of time between packets, but at the same time this video was over before I knew it! Fantastic explanation as always, and lovely to see you again as a guest, Chris.

Chris is a great mentor. His knowledge, personality and demeanor lend himself to being great. Always enjoy his content, thanks for hosting him.

[chrismoore]

Thanks Chris/David. Chris I love more detail than less detail when explaining different things.

[dingokidneys]

These are always fascinating and as for the digressions, I'm OK with them because you always come back to the point you digressed from but have also imparted some breadth to the discussion. I could always jump ahead in any case if I found them unhelpful.

[wadebrumbaugh]

I ❤ the detailed tangents. In this case (29 min mark), it helped me understand where in the process the capture actually happens and why they show larger than 1500. Keep the details coming.

[kovi]

No lies, the detailed tangents really help expand on the why of it for me. Great video guys!

[jgl]

I watch lots of your videos David but damn!!... this has been one of my favorites by far.
Please we need more content like this 🙏🏼🙏🏼🙏🏼

[Tech-wise-]

Thanks Chris Greer and David Bombal.
Getting in detail is actually good as it further clears the concept of what is behind the stuff you're imparting.

[marvelousekpenyong]

Love the details and tangents because it helps me understand more of the big picture. Awesome content and I'm going to get lost in your channel, Chris. Thanks both!
