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... 😥

If I understand, this is less a complaint about how UNIX works and more a story about the consequences of careless mistakes.

This is why we have KVMs I guess. Though not every server has one of those.

I've been trying to find a network capable KVM for home use. They're all pretty expensive or lacking functionality. I don't actually need one or I'd pull the trigger, but I sure have been tempted.

Check out JetKVM

Nice! I currently have a PiKVM but haven't been able to get it working with my NVR. Maybe this would work better.

I had a remote relay box: 8 channels of power control, so I could at least power cycle machines from remote when all else failed.

I actually ended up not using it much at all, it was a nice security blanket, but the last time I decided that I wanted to power cycle something was about 6 years ago, and at that time I realized it had been over 3 years since I had previously used it, and that usage was more of a "let's make sure this thing is working like I think it should" test.

I don't buy servers without iDRAC enterprise licenses. It's too damn useful.
