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