Problem:
I’m using Ubuntu 14.04, and after a power outage I can’t connect to the server. I’ve connected to the server using vsphere web client (but you can do the same through console as well), and ran: ifconfig command, but I didn’t see eth0 at all.
Afterwards I ran the following command: ip link
And I saw that eth0 state is “down”.
Solution:
In order to enable the network adapter I ran: sudo ifconfig eth0 up , and saw that eth0 is back!
Idit 🙂
