Linux Networking that you need to know (Episode 3)

[@davidbombal]

You need to learn Linux. I've said this for a very long time. Occupy The Web says the same thing - if you want to learn hacking, you need to lean Linux. This is a fundamental skill. This is episode 3 of the series.

I'm 40 and just starting out in tech as I'm going for my CCNA. Watching and listening to David and his guests really is quite inspiring. I have not been this excited about learning and growing my knowledge of something in years now. I feel alive again.

[@maverickmace9100]

Good luck. You can do it. Im in the same boat. Im 40 and just passed my CCNA.

[@PrinceZiim]

Nice, I think the most annoying thing with Cisco u will come across is how Cisco will commonly interchange words, for me it was a bit annoying and sometimes confusing

[@piternoster]

Same here, I am 40, now trying to change career. So excited!

[@royalcanadianbearforce9841]

Thank you David and OTW! This series is an absolute treat to be listening to while I work on my Linux Foundation + CKA certifications!

[@davidbombal]

Great to hear!

[@terrencebanks8862]

I appreciate this refresher on Networking Fundamentals in relation to Linux. It is good for those outside of Linux also.

[@davidbombal]

Glad you enjoyed the video! 😀

[@josh-sr2nt]

You both are the reason why I'm improving. I started this journey with you and decided to do on the way you recommended. And I got you now SIR! I even can say from where I am now, that knowing Linux as an ethical hacker is 15% of the job in terms of network hacking. It offers a better understanding of tools like Nmap. Really thanks to you all.

[@cock699]

😴😵‍💫

[@jasperthetom]

Thank you so much David(sir). first thing is that you recommended this linux basics for hackers to read so I purchased it and learn every day and now you are uploading these videos on that book is simply amazing for me. That's so nice of you.Hats of to you guys.

[@offensiveredteam]

First chapter, OSI layers and their corresponding attacks, very impressive explanation. Thanks David for having OccupyTheWeb

[@a.iananda1215]

This can't get any more greater than watching my favourite youtuber and my favourite hacking instructor . Thank you for all your hardwork . can we expect to get the series of 'Network basics for hackers' & 'Getting started becoming a master hacker' ?

[@davidbombal]

Thank you. I'll ask OTW 😀

[@mattbaker1683]

Absolutely top notch content right there, thanks to David and OTW. For someone looking to get into the field of ethical hacking and cyber security it is massively insightful to get a hacker's perspective on the subject, what works and what doesn't, the why as well as the how to. Please give us a heads up when you are going to move onto the other books, I'll buy the others and follow along 😂

[@Nerzhina]

Kudos to you David & OTW. Your KZbin channel & OTW website video tutorials are two of the best ethical hacking learning resources on the internet. Please continue your excellent educational work.

[@CanadaEhhhhhhh]

Priceless High Quality knowledge for everyone. I hope that everyone was paying close attention to all the details. If not Id rewatch the video again! Great Series! Wish this content existed when I started learning networking. This also Serves as a good refresher for IT Professionals.

[@nathanblair7699]

Thank you so much for this! I am just starting in cybersecurity and found this to be the most effective way for me to learn. The dialogue between you is awesome, to hear a conversation about the topic and not just someone speaking at me. Thanks for all you do and cant wait to see more!

[@cmodlin837]

Love these series with you and OTW. Thanks to both of you for teaching us about cybersecurity and how to protect ourselves and friends and families.

[@elexbeats]

David, I understand u have a very begginer subs base but it will be good sometimes if you interview or do a collab with someone much more pro and to explain some pro hacking methods.

[@TherealKeyserSoze-ff5fx]

Do you know about the babylonia method? It is only spoken about by the code 9 hackers

[@chrisherd991]

I just bought the book. I consider myself at preschool level in linux. It is the best book I have read, a lot of”easily understood” content in very few pages.

[@ItsMePhoebe]

I love this series, my dad got me OTWs Linux for hackers book but I haven't read it yet, however I'm loving the opportunity to get this knowledge in easily accessible, video format also 🙌 Thank you!

[@burgek1]

Loving this series and really appreciate you and OTW taking the time and effort to bring us this content. I'd be interested in the mitigation side of this stuff as well - honeypots and IDS etc.

[@Ericer-cc1cz]

Just done watching your episode 3 , can’t agree more, learn the basic Linux or go deep Learning Linux. Your guest is really (OTW) good. I owned some of his books (Linux basics. For hackers) and I pre ordered the 2nd edition already. Your guest really explain well and slowly. That’s makes me feel comfortable and learned /understand everything. Sometime this year I might take a bundle course (cyber..) who know I might contribute to the cause…

[@danquixote6072]

I just bought this guy's book, the Getting Started to becoming a Master Hacker and found his website. As a beginner, I wish I had found it ages ago. His Linux for Hackers book is good too but had a few problems with the install on my M1 Macbook.

[@bladimireth3810]

Can you get a course from him ? Please help me I want to learn

If you're trying to run Kali Linux on the ARM64 architecture, I recommend using UTM (similar to virtual box) but provides support for the M1 chip.

Thank you for making these videos. I've actually already discovered and know about most of the content so far in this series from my own curiosities over the years but I've never been introduced to any type of formal training or anything as my knowledge has been built on my own curiosities. Anyways, I've always wanted to do a computer security type job but didn't know anything about the industry at all nor what path to follow. Anyways, thank you both for showing me I was on the right path. I'm definitely going to enter into the industry formally.

David, thanks again for all that you do and all of the knowledge that you share. I just watched the third video in the series and I noticed when he changed his mac address to 00:00:00:11:11:11, and then typed ifconfig, the mac address had changed but he did not have an IP address. Do you assign a static ip to your network card or will you still be able to get one via dhcp? did not get a chance to try this as yet. thanks again

[@GyrusAssimi-wb3jw]

Dud the way sir Ocupy the web is though at Networking is just Amazing, like listening to you sir David and your brother. What his hieghest certification please ??

[@user-gy9vr9qe1e]

This is probably a stupid question, but here it goes: When attempting to impersonate a device and gain access to a network, how exactly do you access the network and evade security mechanisms such as intrusion detection systems mentioned in the video? And how do you research and understand the target network? Also, how do you know if you are hacking them and not the other way around? I was thinking about this the other day, what if they leave everything vulnerable in order to lure you in and hack your systems? Thanks in advance. 🙂

Thanks again for this series David and OTW. If anyone cares to answer me, i have 2 kali vms on vbox. When i run ifconfig on both, it shows they have the same inet. Is this because both are on nat? or did dhcp mess up somewhere while allocating the addresses?

nmap is legitimately the most underappreciated application. I know other IT professionals that use inferior tools not knowing that nmap is like the best swiss army knife of networking. They always make comment "Oh you work in security" and I always say, well, yes, but nmap is great for more than just security.

[@TheBlackmanIsGod]

The reference to the "original internet only having 4 nodes" is a popular myth or misconception. It's not accurate that the original internet was limited to just four nodes. The "4" in IPv4 actually refers to the 32-bit address space, which allows for approximately 4.3 billion unique addresses. The concept of IPv4's 4.3 billion addresses is derived from its 32-bit address structure, not from the original internet having only four nodes. In reality, the early ARPANET (a precursor to the modern internet) had more than just four nodes. It was designed to connect various research institutions, and while it started with a few nodes, its architecture was not limited to just four. IPv4's address space limitation became a problem due to the exponential growth of internet-connected devices, leading to the eventual development and widespread adoption of IPv6, which provides an immensely larger address space to accommodate the increasing number of internet-connected devices.
