I have encountered a series of errors after my Ubuntu server was restarted. It seems to have forgotten how to connect to my router as it cannot ping local or other IPs.
When I start it up it says
Waiting for network configuration Waiting 60 more seconds for network configuration
If I enter ping http://google.com it returns:
ping: Unknown host http://google.com
If I enter ping 192.168.1.1 it returns:
connect: Network is unreachable
If I enter /etc/init.d/networking restart it returns:
Reconfiguring network interfaces...
then hangs until it says
Failed to bring up eth0
Currently the networking/interfaces file looks like this
auto eth0 iface eth0 inet dhcp
The router reports that the server is: Inactive..
