I LOVE the way of David talk. Loud, clear and very calm words. Im not a english expert, but i can absorve every word wich David tell´s us.

i feel like this is the only hacking tutorial I'm comfortable watching

A tip for Linux beginners: if you aren't logged into root, you will have to type "sudo" (without the quotation marks) before your terminal command.

This was a great demonstration, bringing together Kali/cybersecurity tools and Cisco/CCNA fundamentals and applying it in a lab scenario.

Him: *Teaches you how to hack* Me: *Ends up hacking the Pentagon* Him: "You weren't supposed to do that!"

i have only one word to say, and it's "EXCELLENT"

David, you are a master at explaining complex topics thoroughly yet with such concision. Very easy to follow along & you have such a wealth of knowledge. Thank you for taking the time to post these videos on ethical hacking techniques to help people, such as myself, protect their personal IT environment.

Honestly I love the way you teach, I've been watching your videos even before I get certified and you helped me a lot with your content for the exam, I hope one day to be as skilled as you

Great to see you putting out Kali-based material, David. Looking forward to the others!

Why my yersinia don't "have GTK support" or "is configurated with --disable-gtk option"? How I can solve this?

It has been one of the most meaningful videos, God bless you for the information you have given, you are a perfectly knowledgeable and intelligent person. Living at the same time with you gives me great pleasure.

Woah, I just randomly found this video in my recommended, and after listening to you for a bit I realized "Holy Crap, I'm taking this mans CCNA course on Udemy" Amazing course btw!

Just purchased your CCNA course. I first completed CCNA and CWNA back in 2005.. it's been a while. Your course looks very well structured and looks practical/interactive. For $10 bux I highly recommend it. Will post more feedback after I've completed it.

love the video, graphics, talked in a clear voice and the information was all awesome but best of all, i loved his accent! :D

The yersinia is not working in kali linux 23 the error is coming of not supported GTK

i found a nice place for my studies... just finished CCNA1 intro

Not long got my Net+ currently studying Sec+ this is great information thank you

I'm studying for CCNA...and this is an awesome video. Now I really understand why I need to networking knowledge to be a hacker. I didn't know STP hack before. That's awesome too. Thanks David.

Great video, well done David! I started to use yersinia and macoff as an ethical hacking tools, collecting logs in 2015. One of my customers didn't believe that someone could stop his network. We scheduled a non business hour and I flooded his network with more than 65000 mac addresses using two simple linux. His switches collapsed within mac moves notifications. Even his uplinks and downlinks entered in error-disable mode. There was upon a time when dot1x came out to play...

Omg I’ve been waiting for this series on your channel for some time. Your content is amazing, I love your channel!

aww god i recognize this voice from the endless hours of CCNA study you damn near killed me with that monotone voice....but thank you so much i passed my exam hahaha

You're amazing David! Thanks so much sir. I am enjoying and learning so much from you. You make it so enjoyable to learn all these new technologies. Many blessings.

im having an issue with yersinia. i cant use -G for the gui and there is no error message or anything . im using vmware workstation 17 running kali linux 2023.3 please help Thankyou

many learning channels on the internet, you are very good David. I love your effort for videos and good explaining.

sounds great, can't wait to see the second part

Our day is 24 hours and this video is 16 minutes that can change the rest of our life “Thank you”

I love how this get the most views out of everything.

Absolutely amazing tutorial. Great work, please keep them coming.

Great David! The best teacher ever!

Thank you for your videos, especially with Neil Bridges. You interview was very supportive to newbies joining the industry at later age. Thank you

This is a great tutorial for a programmer that jumps ship to cyber security.

Easy & effective. I've been learning ethical hacking for a long time so that's nice to come back and see Yersinia. I'm looking forward to see more videos from you.

Just passed my CompTIA Network+ last month and I'm glad I was able to follow along (for the most part). Saw some new Cisco protocols that weren't covered in Network+, I didn't know CDP? Have to look those up along with the program tools. Obviously Cisco proprietary protocols. With so many Kali tools it was good to see a list of them on tools.kali.com. Now I can go and research all of them and see what's available. Awesome content, and don't be afraid to plug your courses. You put out the best explanations and walk throughs.

Hello I have a problome with the Yersinia , yersinia Gui is not open i can use but in CLI not Gui , Gui is not open please Help me.

Incredible David, your all videos are always very helpful for me. Thanks a lot for whatever you did till now, and expect more from you in future.

He is probably hacking us while we watch this right now

Great! I believe that should be interesting to see a série of videos showing how to configure a web server against attacks.

David . Thank you so much , you really know how to explain hacking matters. The only one, other channels (I am not saying any names),they don't really teach you much and we the "Students" , don't learn pretty much anything that could be applied to the real world

hey, my yersenia dont open the graphical mode, someone can help me please?

It was damn interesting man... I loved that hacking... waiting for your next videos...

This Guy is serious and so am I , first time activating youtube bell just for you man.

Hacker: This is what hacking looks like! Movies: Who cares?

finally somebody shows a realistic looking rack room in his intro. Whenever anybody shows a rack room it usually looks like a goddamn ufo spaceship. Reality is usually a jungle of cat5 and fiber

That’s great. I’m doing Master of Cybersecurity in University, but I think I would learn more from your channel 😁

I didn't usually comment on KZfaq....but your videos....loving them..!!!!

Great David, your videos contain all the information that I need. I appreciate what you do, thank you very much David.

Thank you so much Mr David, your explanations are so easy to understand. Looking forward to new courses :=) Thanks again

Very Good, Thanks You are doing well. this is a good online course ever i have learned from.

Great presentation David, keep up the awesome job you are constantly doing!

Him: Here is a way to hack a network ME: Let's cancel my Verizon subscription

This topic is super complex for beginners ! wished an explanation to the network protocols as that is super advanced for the first video after kali installation

Thabk you dude. You're great . I'm doing MBBS but I also love networking realted topic.

DAVID THAT'S COOL. YOU DID A GREAT JOB WITH ALL OF YOUR EXPLANATIONS.

I became interested in hacking due to boredom during the pandemic. I did some research. Found Kali. Downloaded it with someone’s instructions ( won’t name you tubers name). Then had to delete it along with the VM. Did this about 3 times until I found you and the dude with the beard. 🤔.... forgot his name. Something chuck. Point is thank you both so very much for allowing me, which had no computer knowledge whatsoever, I mean, I would create a profile and immediately couldn’t log back in. Lol. Thanks guys

finally, someone who isnt cringe and actually knows wtf they are talking about!!! thank you!! ive been wanting to learn this for so long and nothing ever worked until i found your channel thank you so much!!!!

Loving the "Afrikaans" accent thanks David !!! David im currently in the Insurance Industry , what will be the best way for me to get into the IT Sec industry in SA? Warmest regards and keep up the great work!

Me: about to go to bed KZfaq: Wanna learn how to hack?

I'm waiting with impatience for the next part :)

Tried this on my home network with an old Cisco Catalyst 2960. Very cool to see it in action! Thanks for the great video, David.

this is great! I'm in for the entire Series>! great explanation . keep it up

I'm waiting with impatience for the next Part. Greetings from Poland :)

I really don't know what you are doing right now coz lm new. But all l can say is you are a very very good teacher

I hope someday, I can do as you do 👍

I'm new to this knowledge of Ethical hacking and till time this video is most helpful..thanks sir..when is the next video up?

Ohh this is Great. Everyone should become hacker(White hat).😍

From zero to Hero. thank you so much sir, looking forward for Part 2 :).

you are a legend i swear other people would have taught this in 2 hours

I tbh dont get anything im just scaring my mom into giving me the tv remote

You're the finest, David. Thank you.

Assuming you can get physical access to an unsecured switch.... anyone with security that poor deserves to get hacked. Still, a useful tutorial for network admins who want to make sure their networks are hardened. Thank you.

After watching this vlog I want to learn atleast something about hacking, thank you david sir!

You are my admirable teacher.

[Everyone after watching this video] "I'm gonna have to go into hardcore hacking mode"

Can someone please tell me what accent this great man has? I would like to know. English is not my native language, I just learn it. And this man has such a clear pronunciation and a pleasant voice!

I m a new learner and I love your way of teaching

Hello David! Thank you for this course! I'm an application security tester learning infrastructure hacking to conduct full pentest engagements. This is great help for me to move forward in my career! Question is there a way you can create this lab without a Cisco switch? Can this be done with GNS3 and configure it as a Cisco Network?

Hi there. Im totally new to kali linux and when trying to run command yersinia -G it shows me that i dont have GTK installed. I dont see any tutorials on how to install GTK. Do somebody know how to instal GTK?

Thanks for not being like my math teacher who can't teach anyone You got a sub

David, you finally got me to sub with this video! Love you man! I'm in!

Your video is awesome , thank you so much

I love your intro/theme song!! Best I have seen

It’s 12:30 am and I’m watching this yay

I can't wait to do some educational purposes with these info

Hello David! Hope you will make a full Kali Linux course from A to Z, like your GNS3 Cisco CCENT / ICND1 (100-105) Complete Course.

Interesting contents and well explained . Thanks !

hey David h r u, thanks for your videos on Ethical hacking. I learn a lot. It is my humble request to you please bring one complete series on Ethical hacking from scratch to Pro. I hope you will.

Ask me again? Sir, I subscribed the channel at a glance. I love hacking the most.

Hey, David Do I need to know how to code to be in cybersecurity filed / or to be a hacker?

I am having problem while typing sudo yersinia -G What should i do?

I hope. I See all your videos in your channel. Just need time for that Finally, thank you teacher.

hello, i have loved your video so far, but i am having problems with installing yersinia. this is what happens when i tried it. my kali linux is the 2020 version. kali@kali:~$ sudo apt-get install yersinia Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package yersinia it seems weird that i had to type 'sudo' before certain commands, and i dont know what that means. i have a really strong will to become a hacker, but i am absolutely clueless about computer programming and i know nothing about hacking. im really interested in this topic and would like to learn more about it. could you please further explain about the commands you used? e.g. what does 'apt-get' do and where else can i use this command? what does 'sudo' means? also it would mean a lot to me if you could tell me more about how to become a hacker. where should i start? which programming language should i learn first? sorry that i have a lot of questions, but i am generally intrigued, could you please tell me more? finally, thanks a lot for these videos, they are very clear and if i do a bit of research, even a dumb dumb like me is able to understand. keep up with the videos! i love them.

Gonna like and comment every Bombal video that is relevant to my learning track. That's all 'em, just about. (Deep breath...)

If for those who have a problem with Yersinia not opening, i recommended you using Parrot OS, which I think it's fine that you can use it, just the exact same thing with Kali Linux

I hack my girlfriend phone and now she broke up with me

Aqui é BRASIL 🇧🇷 VALEU AMIGO♧

Makes you understand CCNA better

You're tone of voice makes me trust you so much. But because I'm aware of what you can do, I'M NOT SURE

Wow, i have seen 2 minutes of videos and i can hack girl's heart lol
