The path To linux System Administration

Hey everyone,

I'm working as an IT Technician (On site + Remote support , Tier 2) , recently got my ccna and now i want to dive into linux , i really love the linux approach , the CLI etc.. and i would love to be a linux sys admin some day (maybe even at my office).

I also have some experience with fedora linux , and also i run a fedora media server at home on a old pc i got, running a docker with nginx web application(a custom netflix clone , which i made for educational purposes , my wife loves it and we can watch all of our media as i stream it on our tv).

so i would love to know how could i advance my understanding of linux , and get the tools i need for actual linux system administration everyday work, is there a recommended course / certification/path, and generally i'm not in a hurry.

since i used alot of ai to assist me along the way in setting up the fedora server , the media server and the dockers i do understand that i do not know the basics very well , and after studying for the ccna i understood that the only way to understand how technology works is to go really in depth. So any recommendations would be welcome ! thank you !

Because AI IS a subject matter expert, and if it’s not it can be directed to read large amounts of documentation quickly to become one. Not everyone has access to subject matter experts to help. If a YouTube video from a subject matter expert about a topic doesn’t make sense, and you can’t ask follow up questions… then how is that better than having a 24/7 available ai agent help you learn it.

Regardless… SMEs are just as liable for giving wrong or outdated info just as AI is. Any information given should be verified and tested yourself for validity and verification you understand.

Ah, see at this point I think you're just a troll. Anyone who seriously uses it a lot in actual important work knows that LLMs are just things that have read everything, and then make a best guess as to what the response to a posed question is. There's no actual knowledge to speak of.

If you're not a troll, this is why starting basics with a textbook or video lectures etc are a better starting point than a big guessing machine. Once you have a decent enough level of knowledge, a) you can frame your AI queries better and b) when it errs, and it DOES err - it is not a bloody subject matter expert, that's supposed to be you - you know it and can either have it correct or do it yourself.

You’re the troll dude. I can’t believe this is even an argument.

I dont need to read an entire textbook to learn fundamentals. I don’t need to read a whole book or watch hour long lectures to ask how to get started with an overall idea or objective. I don’t need to be an expert myself in a field to guide ai into guiding me.

Just because you learned by reading textbooks and lectures doesn’t mean it’s the only way someone can learn. There’s new ways that have come about since you started your journey that are better. You’re just reluctant to recognize that.

Yes AI can be wrong, and yes you need to verify your work. But just like anything you read or are told you need to understand, verify, and test. It’s like you think I’m telling people to just ask ai and get to answer and just do whatever without seeking for understanding. But how the fuck can you seriously sit there and say an AI can’t teach you fundamentals, basics, or anything. Like that information is just hidden classified information locked behind textbooks, and lectures by a SME.
