I am surprised that your subscriber number is that low. There is such a wealth of knowledge in your channel.

I started with you about a year ago and you took out alot of the intimidation factor for me (but I'm going to admit to a bit of that left still at the time). Fast forward to now, got a couple of certs under my belt and some classes and necessity drove me towards truly trying to learn Wireshark. I knew exactly who to turn to. I have watched/worked through your Intro Class, Masters Class, and just finished "How TCP Works" series. With more context, I truly appreciate how easy and digestible you make these classes and how you walk us through (over time) every setting, option, and relationship. Many many thanks for the resource you've created for us!

Absorbing this like a sponge . Thank you Chris

[joerockhead]

Thanks, Chris. I like the quick tips format.

[EricBrokeIt]

imo RTT is such an overlooked metric. how many times have app people blamed the network as slow, take a capture and POW... look here your network rtt is sub 1ms, aka not slow.

great as always Chris.

You are a master Chris, I love your work.

[VishalRaoOnYouTube]

You are a legend, Chris. Recommended highly by David Bombal and his guests. Would you please do a video on WCNA certification and associated exam? Do you think it is worth the effort and cost? Thanks in advance!
