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… 😥

    Not SysAdmin but about a year into my first software engineer job I was working on the live DB in SQL without using BEGIN TRAN ROLLBACK TRAN.

    Suffice to say I broke the whole system my making an UPDATE without a WHERE clause. Luckily we have regular backups but it was a lot of debugging with the boss before I realised it was me that caused the issue the client was reporting.
