[@squirlmy]

the point of the cubes is "gamifying" the exam, exactly the same way games, especially smartphone games, are made addictive for users. You might think it's messed up as a professional exam price, but it is "state of the art" way to maximize income, especially as many of their students will probably never work professionally in computer security, (yes bug-hunting is a possibility, but that's usually not a decent income) It also let's people try without putting too much money up front, which I appreciate. I don't like it as an entire certification price structure, but it's not just a choice they've made by "mistake". It's very deliberate.

[@stuffy24]

I've talked about that specifically in my videos. I know it's very intentional. That's what I don't agree with. They don't care a lit progressing the profession they care about profit.

I was a little frustrated at the question "what is the home directory of the user", because a legitimate answer should be "/home" That's always the "home directory"! In 1999, I got a Debian 2.0 CD, the first bootable Linux CD (you had to boot from floppy and copy CD content to hard drive before that. -Years before the image got put on the internet, so yes, the internet image is going to be 2007, not 98 or 99. Also the m68k version came out much later than i386) This is a clumsy mistake, probably not a big deal for 99% of users, but it makes me question if I want to spend money on the more advanced courses. PS I corrected school standardized school exams as a seasonal job, this is the kind of thing we'd give credit to students for a poorly worded exam question.

i think crystal modules are hard but it is worth it if you come back and do revision. at first its difficult linux fundamentals but as you go across the content you just go along with the flow

I would somewhat agree with you to break them down into smaller sections basically but HTB is not for people who just started and its by design i would guess.

Outstanding work. This was a great instructional on Linux, but the "Filters" page was a buzz-kill. If not for this video, I'd still be wracking my brain, which takes away from the instruction material and the lesson to learn.

At 22:33 why "sudo" isn't a good answer? I think I don't even understand the question properly. At the list above it says: sudo = Execute command as a different user. I'm confused.

[@stuffy24]

Sudo gives admin privileges. su is switch user. They are different commands. They are asking what you need to use with su to run commands as a different user. So for instance su otheruser --command whoami would run the whoami command as otheruser and not you. Does that make sense?

I think the HTB academy is a little weird at times. a lot of lessons like the listening on the target system at 1:07:46 is never talked about on my academy it never mentioned at any point about netstat or what IPv4 is or how to use ps. I think they change all of the educational teachings and keep the questions even when they get rid of certain modules.

[@stuffy24]

That actually would make a lot of sense as to why you see that!

[@Over_Xelis]

Completely agree. Feels a little frustrating to hit that question and when I search forums for help, there are things talking about netstat and ss that I haven't seen mentioned at all in the lessons. I don't mind solving a problem, but it's hard to wrap my head around why we're using something that I haven't seen yet or how I would have known to use that at all - if I hadn't looked it up.
