So I've been working professionally with Linux-based systems for a few years, and while I'm not the expert I would like to be, I have got a pretty good feeling for the way those systems work. You have the bootloader, the initramfs, the boot procedure, systemd, PID 1, you can check the logs, you have all those little things that make the system work. Everything is a file, you have file permissions and selinux contexts, you have networkmanager, systemd units, you have (system) users, some just for some services, it's all dandy.. if I have a problem with a program I can usually debug it, check its logs, and get it to run.

Now for work I suddenly need to do lots of administration of Windows systems, Win11 and server, and troubleshoot deep, weird issues..

And I've started reading up on it, trying to use PowerShell as much as I can, but I'm just not getting the same high level overview feeling of understanding of how the system works, of how the parts work together. Or even what parts there are, and what they do.

(Especially within an Azure context.)

Books on Windows tend to be very surface level, just instructions on what menus to click through to get a working configuration.

But what's going on underneath the hood? What do I do when I get a weird VPN issue? I mean, there's Get-EventLog to check for things in the logs, but.. nothing feels connected.

Do you know what I mean?

(Also, how cumbersome is PowerShell? No proper paging like with less in bash, I mean, you can't go back a page, not with windows more or that powershell pager command, and you have to type sooo many words.. and yeah, everything is an object, and I see how that can be a nice idea, but man, does that force you to select properties of those objects like crazy. Is this really a good thing, once you have it figured out?)

Are there one-to-one equivalents between Windows and Linux distros that could help me understand? Or is there a really good book that spells it all out, that sets me on a path where I can someday debug ANY issue and understand what I am seeing and doing?

..and I mean, where do I even start out debugging and understanding things like Entra ID issues in Windows365 machines, and hybrid Azure domains.. the Microsoft help usually just seems to be steps on how to configure the stuff, but not understanding how it works..

Sorry, this is all over the place, but I'm just lost right now 🤷‍♂️ maybe someone has felt those same things before and has something wise to tell me?

Could they do it? Deactivate Windows licenses, block Cloud services, access to Office 365 and whatnot?

Hey,

I want to get the CCNA certification and will need to study on my own. I want to buy an old cheap Cisco Router to practice the CLI, but don't want a huge, noisy thing running in my living room.

Do you know models that could fit that? I'm seeing a model 880 cheap on a platform here, e.g.

(Or is it maybe not that necessary to practice with an actual router for the exam? Would some virtual CLI be enough?)

Any help is very welcome :)
