Hey man. Wanted to say that I love your videos. They are super helpful and really exciting to see how you breakdown things. Greatly appreciated. Since I don't have a PC or laptop, I installed termux and kali nethunter on my android and is trying to learn it. It's hard to learn it since it's a bit different from kali linux and i didn't find channels that r as Convincingly good as yours. I'd appreciate if u brought this Android part in your content too. Other than that. Stay safe man!! 💙
what editor?
You are my hero chuck thank you so much sir
i thought the editing was really good!
Great video as always Chuck, but I just wanted to tell you that this new way of editing videos like zooming a lot and making images appear and disappear fast makes it difficult to follow being focused so I prefer the previous way you used to edit videos
Who else noticed that his editing is a different level in this video? .... Really njoyed it chuck 😍
He hired an editor lol. I absolutely love his editor's editing style xD
@@bpmcenos1738 I know...... But still it's just awesome.........
that's why his voice didnt sync with video at 13:50a( #joke )...............btw i love his videos
He hired a editor lmfao
This is hands down the best analogy I've ever seen for sudo. Entertaining, fun, and memorable!
I want to thank you so much for the inspiration and the way you teach us. ❤ Best regards from Germany!
@boby dunne Aber natürlich
vallah der Bürger hat nicht geschmeckt
guten tag
for chuck 👑💪🏻😼
16:38 I really know how much efforts you gave it to us, for making it easier and much simple thank you so much we really appreciate that from you 🥺🥺❤️❤️❤️
From KSA wish you all the best 🇸🇦💚💚💚
Moin Auch mal ein deutscher
I'm a 53 year old Dad home schooling my 11 year old son...and learning with him. We want to set up a business together building and supporting software and hardware solutions using Linux. We both easily relate to your teaching style. You make it fun and relevant. Respect!
I wish you both the best! My Dad teached me html when I was 11 too, now I'm teaching my dad python and linux and he teaches me excel and a little bit wordpress, even though instead of wordpress I actually want to make my business-website completely myself fullstack. Surely I can still learn a little bit about servers by learning wordpress, but I'm very excited about excel. One of my dreams is making a electronics and computer club in my city to bring people together.
@@OneMilian Wishing you the best of luck as well
@@mordor4309 thank you alot kind person!! :) Always happy to hear motivating words from someone else than me! Wish you success in general, luck to be at the right place at the right time, willpower to achieve your biggest goals, happiness to smile and also a wonderful sunday, mordor! And remember, dream so big, that people think you are crazy
How is your business doing?
I love the way that you teach. God bless you (Ethically of course)
God is ethics. TRUTH
🤣
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
I legit just did "user management" in my Cybersecurity course, then this video pops up. MORE LINUX CONTENT MORE MORE MORE
I’m also on that same topic. How’s the tech life ?🙌
Man please keep these coming.. i know this is a sponsored series but i feel like you're the only person that can get me to really learn this combined with HTB. I hope you keep this kind of very detailed beginners tutorial series going even after the sponsorship. much love
Love the way you explain it! Doesn’t get boring over time! Hope you have time to keep making more videos to teach beginners! I know a lot of it but don’t understand how the command works or the operators. You teach how to understand the kernel and commands! Thank you!
I enjoyed a lot watching this video 🙂 ,specially the editing.
BOTT
I've been tinkering with Linux for many years now off and on. Your videos are very informative and entertaining. I can listen to your teaching videos for hours. They've sparked my interest in learning Linux again but this time really learning it. Awesome job brother! Thanks. Keep em coming.
I started learning linux because of you! Thanks :)
Loving the way that you makes education easy and fun ❤️❤️
If you were my teacher in college, I would've been a linux pro today. It took an interview for me to find you on youtube. Thanks for all your efforts and I am currently binging your channel. You are the best CS teacher I've had.
The amount of work put into this video is scaring Thanos, Good Job!
Thanks Network Chuck for this series you’ve created! I’m just getting back into Linux and it’s super helpful! Please keep em coming sir👍🏽
I love your teaching style man. It is so engaging. Also I noticed that you have slightly changed the editing style to add more fun. I like it!
So far, this dude is the best teacher I've ever met. He always finds a way to make things adapted to real life. He makes Linux sound so easy that one can learn it just for the heck of it. Real, funny, and always on point. Thanks Chuck!
You explain everything in detail which I had learnt by exploring, for the past 2 years. This is amazing bro!!!
I also have recommended your channel to people who asked for ethical hacking courses and Linux tutorials. They'll never get disappointed :)
I can watch him for hours without getting annoyed and learn lot of cool stuff.
He always keeps you interested and motivated!
Excellent job Chuck 🔥👌
Hey! I need to get password with kali linux but I can’t understand that can I get passwds from discord or somewhere else?
@@Martin-fb6hh what do you specifically need?
@@ricardomilos2219 hmm maybe discord or gmail.
@@ricardomilos2219 I want to try to crack password of account on discord
@@Martin-fb6hh sounds like something illegal tho...
holy the editing on this video is amazing!
You have been such a HUGE help in my journey to becoming an ethical hacker! I love the way you explain things because im able to focus on what im learning. Thank you! I'll definitely continue to watch!
You have this ridiculously contagious attitude that makes even people with issues feel highly of themselves. I can't thank you enough. Thank you for teaching me about operating systems, and giving me the proverbial pat on the back that cements the notion that I CAN do this.
13:48 ❤️🌹~ Ladies and gentleman. We got him xD
Yes
I liked the way that you use in teaching. Excellent skills you have there!
I love this series and appreciate all the hard work that you are putting into to helping us understand Linux.
Your teaching method is absolute genius, never stop, i love these videos and am learning sooo much thank you for your content.
Ah, my favorite episode of the MCOS
(Marvel Cinematic Operating System)
To say the least, the legendary explanation thx chuck 💕💕
Thank you Chuck ! I love your teaching style and sense of humor ! Feels like we are having fun while learning, never thought those two words could be in the same sentence.
Love the analogy and teaching process Man, most probably this is the best video of Linux i have ever seen. Hope this series will continue. Like to watch more .
You're a really good teacher man! would you please dedicate one episode to 'chroot' command and virtualization through it? that'll be awesome.
Man the way you teach is simply awesome , love you sooo much and I gotta use a pick up line , if you stand in front of a mirror by holding 8 roses you could see 9 most beautiful things in the world 😁
@@NetworkChuck how to block poop up on internet pls
You break stuff down in the simplest form to understand, I really appreciate it man!
Another amazing video! I think I've learnt more here in about 4 videos than I have anywhere else! This is crazy! You have an incredible ability to hold peoples attention and make it interesting too!
Also, the only youtube channel I have ever thought of subscribing to...
This is the only thing I look forward to these days!
are you ok?
Thanks Chuck for the lesson. Only problem is I scramble to stop the video and have to try and back up to the point I missed. It's a bit difficult since you talk fast, but I understand that you want to get as much info out there. Also I'm jealous about your computer, it's super fast and I can only two finger type. 😄 That's just the mumbling of a 62 year old. Carry on, I like your style.
I usually never comment in youtube, but the perspective you just gave to me has changed the whole Linux universe for me.
We owe you thank you.
After about a year and maybe a few months, of trying to get into coding. Then learning I wanting to do cyber security. Watching videos. Buying courses, buying apps, and just getting bored. Watching podcast, other people talking. All boring. I can sit here for hours and watch videos then rewatch the videos. I've learned so much and it's interesting. I love it, and thank you. And my 2 bros who I got into coding loves you too. Full support.
enjoying and learning at same time that's what we are missing in the college
it's crazy coincidence but just yesterday my teacher taught my class on managing users and groups
I am watching these series while my quarantine days, unfortunately I sent my pc to the service last week, but luckily I have an access to a linux server via my Ipad, so yeah you're helping a lot bro, I like you're way of explaining things especially the coffee ☕️ break!
Keep it up 👏
Most of your videos are cool. This one is FANTASTIC! I was really engaged with the narrative blended with the lesson. Very well done!
Chuck be like,
Gotta quickly clear the screen.
Ah, too clean. Gotta clutter it up a bit again.
Enter, enter.
Perfect.
Look at Chuck! Making my life just a tad bit simpler🧠
learning with you is like going on a adventure,i've seen many ethical hackers videos,all confuse and terribly bad at teaching,ur just the best,literally the best,can't wait to watch all your videos,im actually having fun with you,usually other people look like they're about to die,you instead,you're always happy and enthusiast
I am currently taking a Linux class in college. This is an awesome video I love the way you teach, thank you very much.
HEY CHUCK YOU'RE EDITING SKILL BECAME BADASS 👌 😉
13:48
It's his editor lol
this is because he is not editing it
in his previous video he told us
The editing was good can definitely tell a difference. Maybe a little too much zooming in to emphasize key points but overall very good quality.
Thanks for the feedback!
I actually LOVE the zooming in & out!!! He's so entertaining, I could never listen to my instructor like this 💀. Whenever my instructor is confusing I come here & look it up.
Using the Infinity Gauntlet and Avengers to teach sudo powers was a stroke of GENIUS! Such a great analogy and fun way to learn it! Keep up the good work my man!
hey man, I love your channel, I love what you do, I love your style.
Your doing some truly great work out there providing free education for those interested in the computer field.
As long as you continue to post content, I'll be watching!
As Robin would say “Holy identity crisis Batman!” lol
Chuck: “And now we have the infinity gauntlet”
Also chuck: sudo rm -rf /
I instantly thought the same thing 🤣
So far you've been the only person to keep me interested in BASH so thanks and keep up the great work!
OMG, you're an amazing teacher. I'm doing this in class and have no idea what is going on, but I'm glad I found your channel
Can you make a video on permissions ? Like chown etc... And how users can access, modify etc... To secure servers for exemple !
@boby dunne ahah it's funny to play with beginners in linux.
@boby dunne i know that's rwx for the user owner, the group owner and the others. I juste asked Chuck a video on file permissions and how it is important in hacking.
Wait a minute , let me get mah☕
@@NetworkChuck you have a custom emoji bruh
@@redci there are emojis for coffee but not for tea 🥲
I just want to thank you because what you are doing is awesome. I’m taking a boot camp now but I feel like I’m missing something. I does feel like you are simplifying this and filling in the missing pieces.
You're the only one who can both make me laugh and learn new things at the same time! Keep it up 💯
The new editor is... in one word
*Hilarious*
Bro love u ..... how do u get that whole knowledge
You gotta study...
@@NetworkChuck right now 😆
Really liked the video. Very fun, entretaining and very instructive! :) I've watched other videos and I really like the way you teach. Keep going !
I love how Chuck does this like it's a story because it really makes it a lot easier to follow and retain
Yeahh let's go Chuck
your first
@@ajiteshkumar aye yessir
Can you make a video on how to self host an email? Also Blackarch
also 1:48 bing really?
You can try iRedmail. It is relative easy to install and configure. Step 1: Get a domain, step 2: install iRedmail, step 2a: answer the questions during the setup, step 2b: restart, step 2c: configure domains and users in the iRedmail webinterface, step 3: Portforwarding on your router, step 4: whitelist your external IP on Spamhause's website, step 5: Enjoy your new self-deployed mailserver. It took me under 1h to get everything up and running on my home server.
@@borisvokladski5844 cool
This worked out surprisingly well. I enjoyed it, and the story telling along the way!
i love the edit omg. it is literally perfect. Plese keep the guy up i want more of this.
bro, you are absolute gem. I never had much interest in learning linux because of the boring lectures which we see here and there, but this series , which is short and crisp, is enough to give you confidence in linux and understand the basic details which are the building blocks of any thing which you want to conquer. Thanks again! Never stop this good work!
There is a very crucial thing missing in this video that I didn't understand until my employer told me. Here's the thing. Yes, you never want to become the gauntlet, but at 14:50 you mention how you can su into the root as a sidenote. It's important to make the distinction between **SWITCHING** to the user, and **CONNECTING** to your box AS ROOT. This confusion almost led me to have my nameserver have a security issue. Yes, I would have implemented this if my employer didn't stop me right there. Other than that, thanks for letting me think about this and you inspire me to become a better networking engineer with your easy to diggest explanations.
the editing is so much better than before good job chuck!
This is so freakin' awesome! LOVE your teaching style and glad I found your channel...
U r the best teacher and a successful CZcamsr. Wow I am seriously with u.
Lovin the longer Linux videos Chuck- keep em comin👍
I have just learned a lot in this one video. I am binging the whole series. Thanks man
He makes easier and less stressful learning Linux. Awesome. Kudos 👌 to network Chuck!
Dude, your videos are amazing! Always entertaining and man I learn so much!
The editing is TOP, really enjoyed watching the video!
I’m on this episode and this was really fun to do, thank you!
Oh thanks Chuck for this video. You really put your heart and soul in order make these videos.
Excellent tutorial. Enjoyed the Avengers theme. It literally kept me engaged and helped me visualize the entire tasks. Thanks! The index you included was extremely helpful to me. Great job!
You are a great person chuck thank you for every video you put out there where people can learn and educate themselves because of you
This was one of the most educational videos i ve ever watched, thanks sudo!
2 years later, still a solid video. Teaching my kids about Linux (in the face of those who say LLMs will do this for us) and really loved this analogy. Awesome work!
This video was a really good refresher, thank you for saving the universe, NetworkChuck!
Wow! What an amazing way to get your point across. I have been using Linux on my home PCs since the early 2000s I know how to do the things I need to keep my machines running, but your instructions really fill in some gaps for me.
ALREADY watched many courses but found it as the best place to understand
The examples in the explanation are just perfect! Thanks a million chuck!
These vids are amazing chuck i hope you keep on creating them💙
Thats why i chose you as my channel to learn how to use kali linux, you have the power to make us enjoy your videos that we get excited to watch the next video, unlike my teacher who make me lose my focus and feel asleep
I watche upto this episode without writing or practicing the commands much. So it's time for me to write down all the commands and practice them before I head towards the next episodes.
Thanks NetworkChuck, you're a great teacher.
New editor? Looking good. NetworkChuck you are not only good at teaching but you are good at editing videos too. 👍🏼👍🏼👍🏼
Your Linux course is amazing! Thefore I already know Linux, but still, your lessons are amazing!!!
Informative AND entertaining! You, sir, are the real hero here!
Love your videos Chuck - I recommend them to all of my SE friends, even though they aren't in IT per se! I've been totally noshing everything Docker Linux and Kubernetes that you have provided! Any-who I just wanted to let others know, early on in the video when you didn't have the permissions to adduser thor, instead of hitting up and going to the beginning of the command string to type sudo and rerun the command you can just type sudo bang bang (aka - sudo !!). The bang bang ( !! ) command is a shortcut to repeat the previous command you entered in your terminal. this is super helpful especially if your command is a beast. Keep up the great work!
Hey, man. Im here to say i dont speak english and I just found you after wasting my time and some money in spanish courses of basic linux to try prepare myself to a hacker.
I learned ( for real) more watching a guy I dont understand ( language) in 3 videos than watching someone trying to teach me this in spanish.
Thanks from my heart.
i watched to many youtuber to learn kali linux but you are the best broo keep going like this, i never gonna change you
Learned alot from this video gotta start making a document with all the new commands I learned tday so I dont forget. Thanks NetworkChuck
I was so lost! But this video right here saved me. Such a great and fun way to learn, thanks!!
Damn CZcams! I had no suggestion of this amazing series. This is the best class I've had
