My Tenda adapter with chipset RTL8192EU not captures bssid always and disable wifi network plz tell the solution 😢

[@erikmorin8287]

It's Cisco U now , no longer Cisco Netacad?

[@xspydazx]

ITs very good stuff tokow : I will create aosme tools from this stuff and give to the large language model : as i have noticed that we dont need to be the "hacker any more " or model or GPT can do this work also and when faced with failure it will keep penetratio testingn : I personally started i networkng but ended up in AI !

[@ayonmsd1265]

[@jeanharvey1063]

This got me to explore 802.1x more closely as BPDU Guard is necessary because 802.1X does not have mechanisms to block or filter BPDU traffic before authentication. By enabling BPDU Guard on appropriate ports, you can protect the network from BPDU-related attacks before 802.1X authentication takes place. I just love your videos as they always make me rethink the fundamentals!

[@davidbombal]

Great comment :)

[@MegaSAGE9000]

I learned something completely new today. Wow, I didn't know that.

[@jeffreyb4193]

You sir, are a genius! Love all your videos. I'm always striving to learn more and you make it possible.

[@davidbombal]

Thank you! I appreciate that!

[@ruhnet]

Love it! I highly agree with your idea that learning with actual devices is better than just simulations. It particularly helps with troubleshooting skills, since inevitably in your lab you’ll plug in something wrong or have a bad cable etc. and have to figure out the problem. I would encourage anyone studying for CCNA to get your hands on some real equipment if at all possible. The old gear is quite inexpensive and readily available in most places, and you can build up a small lab for very reasonable cost.

[@davidbombal]

Agreed. If you can afford it, buy physical equipment. If not, use Cisco Packet Tracer and watch my videos 😀 I've spent thousands of dollars on equipment so people who cannot afford to can learn with me.

[@amparorod2000]

I saw the word Python, so I had to watch this video!

[@davidbombal]

Python is great! 😀

[@roruphotography]

Me too! 😂

Guilty 🖐🏻 😅

[@desordenpublico]

That python does things to ones head 😂😂

[@gopalrajkumar7323]

What I like about Bombal is he is articulate, precise, and speaks with a degree of confidence and clarity. I have half learned a lot of things over the years from Udemy but am frustrated when thy don't respond to queries about common problems or problems that arise from the tutors skipping simple but vital steps that result in inexplicable unnecessary errors. I have discovrred this is because the people who produce those lessons offered on Kali want to direct you to their private teacng portals where they charge you an arm and a leg.

[@brandonhill9450]

I've been struggling to learn. PLEASE KEEP MAKING THESE! you make it so transparent

[@supratikb]

David, your content has been an absolute treasure, and I cannot express enough how much value I’ve gained from your videos over the past 10 months. I’d love to see a detailed, comprehensive video on the evolution of antivirus technology-starting from its early days to the most cutting-edge advancements. It would be fantastic if you could take us through this journey step by step, from the basics to an expert-level understanding, and perhaps even feature insights from industry professionals. Sending love and appreciation all the way from India-you truly are a gift to us!

[@registosngnvision]

Good topic. Showing the importance of understanding the meaning of the command/configs. Because and also the converge of the network is a real issue, we should avoid changing our network topology in any case. this kind of topic push us to be more precise on our settings. Thk

[@Shumi-kr3tc]

Excellent video, seeing physical devices is so much better then watching slides. Thank you for taking the time to make this series available

[@davidbombal]

Glad you enjoyed the video 😀

[@darksora145]

Thank you David, as someone that just finished the CCNA course and am preparing for the exam. This really helps me understand the material better.

[@anvayashakti2374]

Thank you David for amazing contents. You are one of the #1! Please keep doing this amazing work! All the best to you and all your family 🙏🏻

[@Nerzhina]

David Bombal has perhaps the best network security & cyber security channel on KZbin. OTW is correct when he makes that statement. David please continue your intelligent & intuitive cyber security tutorials. You provide a wealth of cyber security & network security education via your website & KZbin channel. Thank you sir. Best wishes.

[@sixandseven8ths]

Its the most genuine, that's for sure. Too many other "creators" out there just looking for some quick clicks and fast bucks. All flash. David is concise and coherent and sticks to what he knows. That's what I like about him and his channel.

[@davidbombal]

Thank you!

[@davidbombal]

I appreciate that :)

[@alfredovazquez7857]

Love!!! that you demonstrate in a practical manner so we can test it and apply it to our work environment. You have a big talent to teach technology in a simple way.

HI David I doing my GCSEs right now and I dont know a lot as you know they teach like basic stuff , and I was thinking If you can make a series for beginner for hacking , I guess other people wants it as well and I just started seeing your CCNA course , thank you for that Its really awesome .

I want to shift my career to IT. I'm very interested in Linux, networking, servers and databases for last 2-3 years, so I would really love to become Linux sysadmin. Today I talked to my friend who is senior developer and he told me that basically no one wants Linux sysadmins anymore, and that he wishes me a lot of luck to obtain this or any similar role, and that basically the only realistic jr. roles I can count on obtaining are this-or-that variant of developer and software engineer roles. Would you say that he's right?

Hi David, I'm new to CCNA and just starting my studies. I'm a bit confused about where to begin. Should I start with the older 100-105 material, or should I dive straight into the 200-301? I want to make sure I understand the fundamentals well. Thanks for your guidance!

[@davidbombal]

The current CCNA is 200-301. The 100-105 is old material, but there is a lot of overlap. The best way to start is the current 200-301 v1.1 course / content and exam.

The CCNA certification is a bit more advanced and does require some previous understanding. I'd recommend Professor Messer's vidoes on the Network+ certification

[@deadcell8081]

What’s stopping you from learning the basics? Do you go to a graduate school and then complain to the professors that you need to learn freshmen level material? There’s plenty of free entry level networking stuff out there, my friend. Like the above comment, check out Professor Messer. Also check out Network Chuck. He has good material to get your feet wet before you get to the geekier stuff.
