Host is unreacheble with static networking configuration via /etc/network/interfaces while GUI NetworkManager is ok
- by Riccardo
I have some trouble setting-up the network interface using the static IP configuration. I run ubuntu 12.04 kernel 3.11.0-22 with the back-ports enabled.
I followed these instructions from help.ubuntu.com but there seems to exist some conflict between the GUI approach (NetworkManager) and the command line approach.
$ sudo nano /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.1.1.50
gateway 10.1.1.10
netmask 255.255.255.0
dns-nameservers 192.168.3.45 192.168.8.10
$ sudo /etc/init.d/networking restart
I than try to ping for example google.com ping -c 3 www.google.com the response is that the host is unreachable. The icon on the top right of the desktop says: wired network disconnected.
If I work using the GUI approach (Edit Connections and so on...) all works great.
Can same one explain to me where I wrong?
$ ifconfig eth0
