- I am not looking to give ccna/cissp exam.

- My goal is to study for network and system admin job. BOTH, specially linuxadmin.

- This is not the first time I am learning networking and security(I studied them in college), but this is the first time I'll be seriously learning networking and security. lol.

- I learn better by videos than books. But if the book is insanely well written, I do understand them. For eg: books like william stallings networks. Or books like colouris's distributed systems.

- These are the books that I'll purchase next week.(Books come cheap in Nepal compared to usa)

- William Stallings network

- Fourouzan network

- Fourozan security

- Stallings security

- Deitel OS

- Stallings OS

- tcp ip explained philip miller

I've looked at most popular CCNA courses at udemy by c.bryant, that youtube guy that also teaches in udemy(i forgot the name), bombal, n. anderson and none of them matches my learning style. If you want to know what kind of courses I like

- I genuinely love that youtube guy's videos, but since he teaches for free in youtube I can't motivate me to watch him. Although he's in udemy, I don't like paying for what I can get for free. I forgot his name, but he's quite popular. That's the kind of content(slides, examples, figures, illustrations etc) I'm looking for but it should be paid and under 20$ (in sales; I know I'm not normal lol).

- I tried arash delijoo 133hrs course and what a load of shit it was! I could not tolerate even 30 mins of that course lol.

I've heard good things about CCNA books. But do they teach computer networking properly or is it just cramming for ccna exam, my objective is to learn, not to pass stupid ccna exam. Say I read stallings/fourozan book how much helpful will these ccna books be? I've read todd lamele book and I didn't like his way of presentation.

I really love learning via exercises SO I THINK CCNA BOOKS ARE A GOOD FIT FOR ME.

Concepts that I need to learn

- ssl

- dns

- http protocol

- tcp ip protocol

You might say you can just use google to learn them, I tried and realized the foundations were really important. I can do my job, but if something new issue happens, I won't be able to solve it at first sight without learning the concepts.

Anything you want to recommend? Please guys, I'll be very grateful for you.

None of the concepts you listed are really specifically "networking" related. Yes, they all tend to use the network, but aside from ssl/tls, are all methods of communication to achieve X. TLS is a wrapper for these comms methods, which provides a layer of security.

Have you tried doing more than just reading/watching videos? You can learn all 4 of these concepts in one go, if you were to stand up a server, and then configure each of the concepts you want to learn, by hand. You can learn DNS by setting up your own DNS server, and setting up a zone, entries, etc. Once thats working, use the server to stand up a webserver (nginx/apache), and install something into it (lots of cool selfhosted webapps around). Now that you have a working webserver and app, you can start setting up TLS/SSL. Rather than using LetsEncrypt, learn the (sadly, pretty terrible) ways of setting up your own CA and certs, by hand, with something like openssl. Now that you have certs, with your own CA, you can install that cert on your webserver, and youve now completed 3/4 of the concepts you wanted to learn. You can pick apart each one of these as you work through the task, for example, learning the various HTTP headers, and what they do, by use of an webapp that has an API on your webserver.

As for tcp/ip; imagine youre obsessed with shaking hands, and you work in an environment where you have to repeat everything you hear as its done.

< ok you talk now

< ok i got your thing about X

> ok cool thanks

< thanks

< bye!

And thats basically tcp. UDP on the otherhand..

> Hey this a joke about UDP, and i dont care if you get it

< (joke received, or not), i dont care.

And thats the protocols in a nutshell. If you want reading material on any of these topics, id suggest their RFCs. They provide conceptual data, limitations, and in depth dives of how the sausage is made.

hello,

idk ... i would heavily recommend: try to read stuff, its much more efficient than watching videos -> eg. time vs information.

additionally texts can - and must - be consumed in a non-linear fashion: go back & forth, mark stuff, read excerpts, follow references etc.

and imho. get your "feet wet" - books / articles / courses / theory is great, but especially in (linux) system-administration most things are acquired by doing stuff / solving problems / getting in contact with the "real" world ... and if its only in the sandbox of your home-network behind some router...

consume howtos / tutorials & follow the references to fundamentals. your knowledge will get broader over time and fundamentals always pay off, but you can't learn it all at once from the start :)

for example: DNS is the basis of all services in a network.

learning how it works and following best-practices pays off not just multiple but a 100 times the time invested to wrap your head around it ;))
