You ever seen these devices? Networking for Hackers and Cybersecurity professionals.

How long did it take you to see something new or learn something new in this video? If you want to be an Ethical Hacker or Cybersecurity Professional, you need to understand networking.

In this video I show you how to capture traffic using Wireshark and Ethereal using different scenarios:
1) Bus topology
2) Hub topology
3) Bridge topology
4) Switched topology
5) Port mirror / port span
6) Network Tap
7) VLANs
and more :)

David captures more traffic than a New York cab driver!

[ProducerBillionaire]

Every time I see that David has made a new video, I really want to watch it as soon as possible. I like your content, thank you )

I got into cybersecurity in 2020 after transitioning from another career. I learned a lot about networks and how they work. Often times I found myself learning about things I sort of knew just from growing up in the 90's with the internet and troubleshooting for gaming etc. Once I got into the career as a SOC 1 etc. I rarely found myself needing to know much about this kind of stuff as we worked with SIEMs etc. and ingesting traffic wasn't my part, more so analyzing it. Not so much today after 4 years I have learned a great deal, but still hadn't seen EXACTLY what you were showcasing today in this video. It's one of those sort of Eureka moments of oh yeah, I remember seeing this network equipment in my library when I was 10-12 in 2001-2002 or so. Really helps not only to learn more about what I "know" but also showcases and fills in the blanks on some of the things I did growing up. At first, I gravitated more to the programming and threat detection side of the house, but networking is becoming more and more of an interest the further I go into the career. Keep making videos like this. Well done as always.

[yassersaied]

Being in Network industry for more almost 20 years… that is the best explanation and demonstration for Ethernet technology

[shekharkumarjha]

Finally a video that shows you all, no just diagram but also how it looks like in real World,

[ChrisGreer]

Ok David, I see you friend!! 👏👏 nice video!

[tammiealexander]

95% of what you explained and did was new to me. I’m trying to build my own home network. Thank you so much for this!! Saved it and will rewatch!

[Kaushik_shivam]

I get much more knowledge from David Bombal channel. It is best to learn from books

[sujitradhakrishnan]

David, I don't have a timestamp where I learnt something new, that's because I'd list every minute of this video! Thanks so much for what you do, you continue to inspire by staying true to your mission - Educate. Motivate. One of the off-putting aspects of learning computer networks is dragging oneself through tons of theory about things that are abstract, obsolete or both. Your walk through takes out that drudgery. Watching this video had me reliving the early stages of my own career, I remember sitting on a dial-up connection and waiting forever for Cisco learning library docs to download. After all that, I'd never seen one of these devices! It would be terrific to see you put together more such long form videos, they make learning so much more fun. Thanks again!

[Nightfire]

Thanks David I've been struggling to visualize this for a while books don't do it justice. Keep up the good work.

[dariusdoku]

You make computer networking fascinating. Good content, thank you sir.

[parinose]

Good day, David. I agree with you on the 'seen' aspect. I definitely learned something. Not only that, I should re-run your video to better grasp the concept of a spanning tree! Until now, due to the book, I had understood that a spanning tree was a device added to a router or a setup that prevents loopback or storm broadcast. If I got you right, we can set it up using the command line. Am I right?
Furthermore, where can we find all the equipment shown in the tutorial to build our own lab and test—and actually grab it all?! Or can we use a software bridge, router, or tap? Many Thanks!!!

[VSha]

From a student perspective, I could definitely say it's much to see examples like this demonstrated and would prefer to learn like this instead of watching diagram and etc, for the networking topologies.

[willielewis]

Is it possible to start at a help desk with a CompTIA A+ cert then work my way up the ladder at that job? Or should I just get my certs first then look for a career?

[knoxsd]

Thanks you for this physical Network topology explanation video using Ethernet Bridge, hub, tap, cables etc. I've learn only network topology logic at the university. Your video always teach new lesson to me. And it's really helps to improve my knowledge, skills.

[CalvinCosta-nu]

David your videos really forces me to study, you are a good teacher . your videos really inform me of stuff I used to ignore or that seemed irrelevant .
I can say you are a really good teacher even for me to learn linux it was because of your khali linux installation tutorials
😌😌😌😌

[blakepennington]

Man U R A AWESOME TEACHER!! Thank you for ur videos I watch them all over and over and learn something new each time I need a usb kali breakdown one day or maybe I’m missing one you’ve already done KEEP UP THE AMAZING WORK❤❤❤ 😊😊🎉🎉

[kimbjrnjensen]

Great to get a compressed Network 101 as a refreshing of learnings from the 1990ies. Well done.

[venturousgamer]

one of the best video i ever seen which is related to networking
make more video like this
