Commandline/sysadmin course in r/linuxupskillchallenge


This month-long challenge for anyone wanting to build Linux sysadmin skills is re-starting again this coming Monday.

"Daily lessons appear in the sub-reddit /r/linuxupskillchallenge - which is also be used for support/discussion. This is a 'rolling' course repeated each month. Does require some serious commitment, but if gaining/growing these skills is something you've meaning to do, then you now have no excuse! "

Any feedback very welcome.

Ethical Linux

This is my first post on reddit, so excuse my newbiness, lol.

My post is about a way to get Linux back to its roots. Once upon a time, Linux/GNU was not just free and open-source, but also was supported by average people who just wanted to make a better operating system than what was being pushed by Microsoft, IBM, and etc. Fast forward 20 years and now we have multiple corporations that anti-thetical to everything Linux/GNU is contributing not just software, but actually contributing to the Linux kernel.

I don't know about anyone else but this disturbs me greatly. I understand that because Linux/GNU is open-source that anyone can contribute, but that's like letting the fox spoil the grapes because it may also run off vermin that are trying to do the same thing -- it makes no sense. Yes, the code is open-source and anyone can audit it -- I get that. The problem is who controls Linux/GNU -- is it the community or corporations? Considering Microsoft is now the 5th biggest contributor to the Linux kernel, I'd say the balance is tipping in the direction of the corporations. Then there is IBM gobbling up Red Hat. There is a point of no return that I fear we are approaching with control of Linux/GNU and we may have already surpassed it.

My question is, how do we return to the days when Linux/GNU was a community project and had little to no input from corporate entities? Is this even possible anymore? I pray that we haven't lost the war even though we won a few battles. If this isn't possible, then what is next for Linux/GNU?

Thanks for reading and hope you all are staying safe.

tls encryption / CA.key / nginx

Hey guys,
I'm trying to use https / tls encryption on my nginx connection and as I never really understood all of this I feel pretty lost. Most of the time I can read stuff, try it and understand but it just doesn't work with certificates.

I bought a positive wildcard .TLD certificate from comodo and want to create those tls certificates using that wildcard certificate.

The official nginx website gives me the following stuff that I need to have for this to work: https://kubernetes.github.io/ingress-nginx/examples/PREREQUISITES/#client-certificate-authentication

But they skip official CA and leave me hanging with self signed.

**My questions are now:**

What do I need from comodo for this noscript so I can use a real external TLD which is part of my wildcard domain? Pem? Crt? [...]
What is or are the noscripts I need to execute?

**Any help appreciated!**

Snaps are neat

I like the ideea of having a stable system and certain packages up to date. In fact I need this to do my job.

As a dev I like the concept that I can distribute my product to multiple distros with just snaps. No matter the licence I chosen!

As a Linux desktop user, I like the fact we are trying new things. We are not always stuck in our comfort zone. I want the Linux Desktop to become more popular and that is never going to happen with "sudo apt install".
Dont want things to change?! Fine, but I do. Choose a more traditional distro, like Debian.

As a dev having personal projects I would like to sell my software and I think with snaps I would be able to do that in the future. But not with apt etc.

I also understand that snaps are still WIP, so we need to have some patience and appreciate that progress is made.


edit: I guess hating anything canonical does is still cool.

Why isn't Ubuntu touch as successful as Android if both are based on linux?

As far as I know, the projects like Pinephone are still struggling with a lot of problems such as getting camera working etc, while Android had all of these essential functionalities even back in 10 years ago. What is the reason?
