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 have a failsafe service for one of my servers, it pings the router and if it hasn’t reached it once for an entire hour then it will reboot the server.

    This won’t save me from all mistakes but it will prevent firewall, link state, routing and a few other issues when I’m not present.
