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… 😥

    This.

    Do it. This saved my life on more than one occasion.

    You’ll think “nah, it’ll be fine” and then at 11pm when your brain’s fried on vending machine coffee you’ll be glad that you did it… 3 times over…
