Hi all! I am restarting my homelab after years ignoring it. I have a Dell r610, I realize its old and shitty but it's what I have for now. I just upgraded it with a pair of L5640 hexacores and 192gb ram for $45. I have gotten every firmware up to date and I have installed ProxMox 8.
I am labbing in order to learn more deeply the workings of windows in a business environment. I am going to set up my own domain and work through AD and related things. I need these skills for a hopeful job in IT, starting at Tier1. I sold myself well enough to land a T1/2 level job but they let me go after a week when we both realized how little I was proficient in.....
However I also want to learn Linux, I have an incredibly basic level of understanding and want to get to a point where i'm comfortable in the CLI instead of blindly following youtube tutorials. I can spin up a VM no problem but once im in I am lost outside the desktop environment. For instance I tried to add a new user on the Prox install so I wasn't logged in as root, and ran into so many issues because sudo was not installed, then my new user wasnt covered in sudoer.
What kind of projects can I do to learn linux outside sitting in the KDE desktop?
