i recently set up my own server at home to run Ubuntu 12.04 server ed. on booting up, i noticed that a message related to networking comes up, and the booting process pauses. the message read something like -
waiting for network configuration
and after a while -
waiting another 60 seconds...
on booting up, I realised that any command which requires a network connection was not working - ping, apt-get install, etc.
on firing the ifup eth0 command, I get the error RTNETLINK answers: File exists. Failed to bring up eth0. I also realised, while searching the web for this problem, that this is probably one of the most common networking related issues - however, most of the questions are around setting up multiple IPs for the same machine.
ifdown eth0 also fails, stating that eth0 is not configured.
my /etc/network/interfaces file has a simple configuration for a static IP:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address xx.xx.xx.xx
netmask xx.xx.xx.xx
broadcast xx.xx.xx.xx
gateway xx.xx.xx.xx
dns-nameservers xx.xx.xx.xx
The strangest part of this problem is that, while I can't connect to anything outside, I can ping to this particular server using the static IP configured in the interface file, and, i can even SSH into it!
I'm really at ends here with this problem, and any guidance is much appreciated.
Thanks!
