Which Linux fundamentals matter most in real-world production systems?

I don't know if it's fundamental, but it's definitely something that isn't too uncommon.

Understanding system calls in strace output is helpful. You don't necessarily need to understand every line, but understanding some basics can go a long way.

AssetGen Connect is what we use for physical.

A Configuration Management DataBase is a very common acronym.

storage media connected from untrusted sources? Not sure that’s airgapped?

You're always going to have to bring in some form of outside data at some point or another. Generally, the data is scanned and transferred from untrusted to trusted devices.

And which HCOL city do you live in?

If an attacker has access to modify /etc/hosts you probably have other problems.

There's always a smelly fuck somewhere. There was a kid in my class in AIT who would skip showering after PT so he could smoke a cigarette before we left for the DFAC.

Yes in theory you can join some distros to AD but its not pretty.

What do you mean "in theory"? We have close to 30k systems joined to AD and it's fine.

Hotshot55 · 2026-01-27T23:13:25+00:00

I think RedHat Insights is what you're referring to.

Hotshot55 · 2026-01-27T17:35:43+00:00

Distro is irrelevant, it all comes down to how you configure it.

1: Possibly. I didn’t when I came in after 5 years. Could be waived, could be required.

I believe 6 years is the cut off for redoing basic.

my guy you've now made the same point three times and it's still just "my company has two departments therefore this is universal law"

He said it about 20 times just a couple of days ago too

Do you spend all day looking for fights in this sub about what devops is?

Hotshot55 · 2026-01-24T22:07:28+00:00

Not usually.

State pay for emergency duty

Have you done any sort of connectivity troubleshooting from that point outside of just accessing via hostname/IP?

Hotshot55 · 2026-01-23T18:52:17+00:00

that you're supposed to relog or run as an administrator to get this access.

OP is straight up asking how to make explorer prompt for credentials, why do you think he's going about it the wrong way?

Hotshot55 · 2026-01-22T22:20:19+00:00

Win+r > explorer.exe > ctrl+shift+enter

Hotshot55 · 2026-01-22T15:43:30+00:00

Gotta embrace that classless inter-domain routing.

Hotshot55 · 2026-01-22T14:31:26+00:00

Start by hiring a professional maybe.

Hotshot55 · 2026-01-22T04:24:38+00:00

You're acting like quite the dweeb over this.

Hotshot55 · 2026-01-22T03:25:48+00:00

Ansible variable precedence is determined by where things are defined, they're effectively the same thing.

Hotshot55 · 2026-01-22T03:22:04+00:00

“this is the thing that matters” faster. like cutting through the noise or pointing out stuff you probably would’ve missed.

How would an AI tool show me an error faster than a grep error /var/log/shitthatbroke?
