From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello all, running Debian 12 right now and really liking this thing. I never ran straight Debian before, always mint or Ubuntu. But anyway....

I'm wondering if you guys could recommend some troubleshooting or scanning tools that help you find errors, misconfiguration, basically any thing that could be wrong with your system. I'd much prefer GUI tools as CLI tools can be a bit confusing.

So my only thoughts are auditing type apps. Don't those comb through your system for issues? I've tried Lynis and it seemed pretty cool, need to explore further. Of course you got your vulnerability scanners which I plan to use. You've got your rootkit scanners and clamv for malware. I just got netdata up and running last night. Now that is one confusing ass app lol so many options and i dont really kniw what im looking at lol. But I'm more interested in the system itself. I know I have some issues within my system. Htop only tells you so much and it never answers my problems when my computer random freezes or It starts overworking and heating, yet no high CPU or memory usage showing on htop.

I know I have networking issues with my VPN and DNS and other stuff. I just lack the knowledge to know where to look and what to fix, so trying to finder more user friendly, maybe more proactive tools I can use to help me discover things within the system that need attention. Overall I just want a healthy, dependable, safe, secure Linux system and I always endupFrankensteining my shit just trying different crap and everything eventually falls apart lol so help with some reomendations please, folks!

You can use inspec to apply declarative rules against your machine and look for deviations (but I don't think you want to be writing rules to check for system sanity). I'd say go even crazier, run Qubes, then run VMs of many different linuxs, and you can break them at will, resurrect them, etc.

Oh lord that is over my head. I tried messing around with that more advanced stuff but just got lost

You might want to start with something very friendly like checkmk, I'm sure there is a open source alternative to it, but I don't know it off the top of my head.

Full Disclosure, I've never used this, but it seems friendly enough

Sorta looks similar to netdata which I recently setup and holy crap is it confusing. I have no idea what to look at and what to do. Didn't realize its that tricky for a newb.
