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.

After almost half a century, I'm still doing it... (lemmy.sdf.org)

So I'm working on a server from home.

I do a cat /sys/class/net/eth0/operstate and it says unknown despite the interface being obviously up, since I'm SSH'ing into the box.

I try to explicitely set the interface up to force the status to say up with ip link set eth0 up. No joy, still unknown.

Hmm... maybe I should bring it down and back up.

So I do ip link set eth0 down and... I drive 15 miles to work to do the corresponding ip link set eth0 up

50 years using Unix and I'm still doing this... 😥

I hope you don't admin any mission critical servers. That's a first year mistake.

Edit:

Hi salty kiddos still making year one mistakes! Down voting this comment won't improve your skill set. You will get walked out at a serious enough outfit for doing something like that to a prod system.

This is a server I was setting up. It's not doing anything useful at all at the moment, hence the lax work practice. The only reason I drove back to work is because it's needed tomorrow and I wanted to finish setting it up tonite.

Gotcha. I disagree with your methodology of not being careful about non-prod systems. You stated you forgot it was remote. What happens the next time you do that but forget it's prod or mix up terminals?

I assume you've never made any mistakes, ever. What an arrogant attitude.

[–] satans_methpipe@lemmy.world -1 points 4 days ago

I have made mistakes. I will make more mistakes in the future. I will not repeat disruptive freshmen mistakes like the one described here.
