Sir I don't fix my linux Whenever I want to install linux in virtual box so many times black screen comes and stuck.

Hi David! I used the affiliate link to support you!

God i am stupid i accidently removed my comment!!

[@Ann-op5kj]

Hi! Can you do a video on software updates and calls being diverted? Motorola 13 downloads a QR Code Scan that can't be removed. It's always on and won't turn off. Also Rob Braxman is good (just watched a video of your featuring him) but when it comes to your calls being diverted he is naive. He insists only governments can do this but I've had to change my phone number 5 times in 4 years because my phone is ALWAYS being diverted. I have gone to the police and have traveled internationally, I'm not a wanted woman... Just being stalked by a psycho. Please do an update to that video! Thank you

[@nolananthony5880]

Thanks! For all your ideas ,support , and general understanding of my social ineptitude . Knowledge is the key to any success.

[@CraigHollabaugh]

Glad you covered suid and sticky bit, its probably the most important section here.

[@GoogelDeepMind2024]

So as a cyber security expert we use a little trick of rolling ("DICE") to pick any numbers used in a password. The best passwords are very long and different from anything anyone would imagine.

[@ServusChristi777]

Is this a joke?

Rolling dice isn't as good as some devices can generate 24 word passwords.

I study this few days ago but I jump in chapter 6 because it's hard sometimes when no one explains to you but now you upload this video. I hope you discuss with Mr.Anon the whole book. THANK YOU MR.DAVID❤

David really deserves millions of subs,cause he don't leave any garp in hacking and cyber security,❤❤❤❤❤❤

[@davidbombal]

Thank you :)

[@andyehara]

He has Udemy classes on Udemy as well. I’m taking his class on networking as a refresher. His classes are very fun compared to some of the other classes I have take. I like more upbeat instructors because it makes it more fun to learn. But this is just my opinion.

[@michi.m]

Awesome, we are back. Am reading the physical book. Listening to the videos to fill in

[@lonwabobrandon304]

thanks for keeping us updated and I'm very new in the I.T industry still studying A+ N+ and fundamental for cyber the EPs really are helpful.

20:22 GOU is described but o is not owner its others as later explained. Great video btw got to learn alot!

[@rami.0092]

Big thanks to both of you. I appreciate what you do for us. And we are waiting for more and more from you.

[@davidbombal]

Hopefully lots more content coming soon :)

[@LysanderDD]

The explanation is good. Octal permission 4000 is called setuid though. The sticky bit is octal 1000 because this makes files sticky (staying where they are if you're not the owner and only have 'inferior' rights).

[@ЯнДьяконов-е9м]

David, your educational videos are awesome! Could you make a video about port forwarding and tunneling?

[@carsonjamesiv2512]

I just finished reading ch. 5 of OTW's Linux Basics Book. I LIKE OTW's book!😃😎👍👍

Thx David. You always have the most relevant and useful videos related to cyber security.

OTW is the man 👌🏾 love his courses

[@John-yx2is]

Thank you both. I love these Linux videos with OTW. David could you please interview Angelina Tsuboi. She is an amazing young woman- only about 20 years old- but works for NASA in cybersecurity. She has created many cybersecurity gadgets and specializes in aerospace cybersecurity such as aeroplanes, drones, satelites etc

[@OrvusOfficial]

Funny Story, chmod was one of the first commands my younger self learnt because young me wanted to get control over some folder in the root. Bad idea for me lol😅

[@uruyuto]

Thanks for another awesome video :D Here i's an idea, maybe you (David) and Keith can prepare a challenge related to this Linux knowledge applied to an real life case of study on cloud/network security and OTW can act as the threat actor. Idk, just sharing some thoughts.

[@Tanhacode]

When ever i see david, i am suprised that some thing new happen ❤

[@TheSecurityAgency]

He made a mistake by callng o - owner. 1. **u** - User (the file's owner) 2. **g** - Group (the file's group owner) 3. **o** - Others (all other users) 4. **a** - All (user, group...)

[@davidbombal]

You are very welcome

[@rusnakhraj7401]

David, I think that in time 20:22 there is a mistake. O is for others not for the owner. U is for user. OTW also mentioned it in wrong way compared to the linux permissions picture mentioned in 11:18. Or am I missing something? Thank you

[@hollywoodhank591]

At second 00:50 i have the same Book in your background!!! Its really nice! Jon Erickson!

[@AnishBhadouria]

Pls make a video with OTW that include topics like "Quantum Hacking.... Q - Day... AI Hackers.... Future of Cyber Security by 2030.... Scary reality of Cyber - War".... It's my humble request to David sir 🙏🙏🙏🙏🙏🙏🙏🙏

You can do this with the Flipper Zero.

[@zanyaboutit]

Misinformation: I was confused because 20:22 says U for all other users but right after that OTW types o+x to give execute permission to others. I searched and found out O is for others and U is for user (owner).

[@zanyaboutit]

And I think it's not David's false (maybe not double checking, if any) because OTW himself said 20:22 part. And right after that he types o+x to give execute permission to others, so OTW was temporarily confused I guess.

[@k_usuan]

Linux's permission system sucks. The lack of NFSv4 ACL's makes using it as a conventional fileserver in a business setting a total pain and often just simply not viable. It also makes Samba integration far harder than it needs to be.
