This is untrue. Understanding what Linux is and widely understanding what it's capabilities are is more than ebough in this day and age. There's stack exchange and various ways you could prompt AI to fix your query/script. Heck, it might even be able to debug if you choose your words properly. - You don't need to be a W11 sysadmin to make simple adjustments and implement some nice (customized) features. Just accuire the basic knowledge by reading docs or through trial and error and complete your task by searching the unlimited available web content.

[@sideswipe147]

@37:00 why doesn't that say MySQL? glogal change means that should be capitolized no? Or did you undo that change and edit it out? Or am I really just not understanding this (explitive self censored; rhymes with spit)?

Yeah Occupy The Web is great. I would highly recommend buying his books if you can.

Another OTW episode! Nice! Also, congrats on hitting 2M! I've learned so much from your vids 😊

I really like how OTW teaches. I get bored or nod off on some people's tutorials but OTW and David's teaching methods I can get behind!

I couldn't agree more.

Hi. I've read the book, but it's a real pleasure seeing again the explanations chapter by chapter. That's just great. I'm looking forward to get to the chapter 3. Peace and love...

Can't wait for Episode 3. I am just getting started and this is just what I needed. THANK YOU OTW and David!!!!

[@glenrivara2353]

I'm a long-time retired mainframe COBOL developer. I've always had an interest in Linux but never really got to learn it. Thanks David and OTW for giving me a window into the world of Linux. I'm looking forward to the next episode of this series.

[@joeblow229]

I envy your level of job-security as a COBOL dev lol.. The only thing I really know about COBOL is that the phrase "We can never fire that guy or let him leave, he's the only one who knows how this works!" applies.

[@glenrivara2353]

@@joeblow229 And then India happened and the large corporations proceeded to move their IT divisions there. People laugh at COBOL because they think "It's Soooooo OLD". Many applications that people use under other operating systems are just front ends and then files are uploaded at night and run through a batch process where the magic happens. Just like COBOL was outsourced soon all the rest will be outsourced. India is a country full of very smart, eager and hungry people. They work for a fraction of what people make here and they are much more willing to go the extra mile generally. The company I worked for outsourced over 20,000 people in IT there. The system I worked on was old and the accounts were moved off to another COBOL system that was even older. That's where it resides today.

another great episode in the series. also i cant be the only one who's secretly hoping for the dynamic duo of OTW & david going through OTW's networking basics book next. not holding my breath for it, the fact this is happening is amazing enough. but yk, i'm just saying, OTW teaching networking, and networking wiz david hosting it, thats an epic mental image right there ;)

Thankyou both OTW and David, I am becoming more confident and proficient in using Linux. I couldn't install Snort on Kali so instead I used Debian to work through the examples. I have been hopping from a dedicated install of Kali on a laptop to a WSL version on my PC to a VMWare version on my Windows Laptop. BTW - I am working through the book and I am finding the video reinforces the learning. I look forward to Chapt 3.

[@muneeb640]

Hi, David. Your channel's a blessing for those who are learning hacking. Thank you for posting such awesome video series. I've just started learning linux like for a week from this series and i am already gravitated into the stuff. Waiting badly for episode 4.

Thanks a looooooooooot. I bought 2 or 3 OTW books and I desperately looked for a solution to use snort but without success and to hear you say in this video that I can use Apache2 in order to advance in learning saves my life and motivation.

Thank you and OTW for this content! With MCSE training and certification with Windows NT and 2000 (I'm aging myself...)

[@tah6746]

Excellent series. I have switched to Linux. I only use Windows, Mac, ChromeOS in my Tech Support role at a School. I have noticed an alarming trend. Mostly with Windows a little bit less with Mac and ChromeOS. However, Instead of making the OS more secure the OS is just using "Security through obscurity" to make the OS more look like it is more secure to the average user. When really the OS is just hiding items behind multiple menus and sub-menus. When in fact the OS is just becoming more difficult for average user to use, and not really more secure. If some one really wanted to get into the System this can still be done. Increasingly I am using the command line to access the programs and files instead of navigating the now many more menus and sub-menus. On the other hand Most of my job is based on fixing the issues with these other systems. In this aspect this is job security.

[@Jordan-cz2hh]

yea windows is walling off memory more n more in hidden things like microsoft edge and then making it more difficult to handle your files in a user friendly way

[@stevenoconnell9105]

Found this really useful. I’m looking at getting into IT but was unsure what. I come from a military background and really fancy having a go at cyber security as a career change. I just bought the books on amazon but how realistic is to achieve at 53 and get a job doing it. Looking forward to the next chapter 👍

Steve u can do it! Hopefully more folks post in your comment. From what I gather yes it's very realistic for u to start a career in CS.

it really did help me on the snort install. like you guys said, the book has a couple year and some stuff changed. I wasnt able to install in like you guys did in the video but it gave me enough so i could and find how to do it myself. Thanks a lot David and Master OTW

When I went to IBM, I took there Cyber Security Pro Course. They taught the Windows and the Mac viewpoint of things. But they especially narrowed the Linux viewpoint! Both Ubuntu and Kali. Yup. It has to be Linux. I didn't even know what a Virtual Machine was at first. Honestly its a life changer.

[@katriniaburt3160]

I am currently purchased classes with OTW's website and i have a quick question about the sed command. mysql is not in either apache2 or snort and also snort.conf does not exist, i have snort.lua which google/reddit says they have changed it to that. Yet, for the mysql example with sed....it has it's own file. I have snort installed with no problems. I just want to understand why mysql is not in either apache2 or snort. If I am doing something completely wrong please let me know. Thank you! I love your videos and OTW. You guys are amazing at explaining, I just want to perfect this sed command with mysql.

I first use Linux In 1995. It was Slackware 2.00 if I remember right. It was much the same. Conf files usually ended in .rc or the last two characters were rc. XWindows (X11) was the graphical system. Distros came on CD ROMS and sometimes floppies. A lot of the computers had no Internet. There was no Wi-Fi. Applications for Slackware came in .tgz files which were first tared and then gziped. Almost everything was done at the command prompt. We had vi and Vim but my usual editor of choice was called joe. (Joseph Allen). The joe editor was several editors. One of them was jmacs where joe acted like emacs. To use jmacs you called joe by jmacs which them hooked it to jmacs.rc. Either a soft or a hard link could be used. I used joe for almost everything One thing I missed when I was working outside of Linux was soft links.
