LinuxQuestions.org - eth0 disconnected / not running

Hi,

I've run into a problem with my ethernet interface.

I had the interface set up statically, then i decided to try DHCP - all was fine and it worked perfectly...

Then I needed to change back to static, so i edited the config using the networking tool in the administration menu (gnome).. now, the network icon in the system tray shows an exclamation mark and reports as disconnected..

Here's the output of ifconfig -a :

Code:

... and eth0 doesn't seem to be running...

I've checked /etc/network/interfaces - seems OK to me; here it is -

Code:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).



# The loopback network interface

auto lo

iface lo inet loopback



# This is a list of hotpluggable network interfaces.

# They will be activated automatically by the hotplug subsystem.

mapping hotplug

        script grep

        map eth0



# The primary network interface

iface eth0 inet static

        network 192.168.0.0

        broadcast 192.168.0.255

        # dns-* options are implemented by the resolvconf package, if installed

        dns-nameservers 212.74.112.66 212.74.112.67

        address 192.168.0.10

        netmask 255.255.255.0



auto eth0

Everything looks in order but I'm at a complete loss. Thanks in advance for any pointers..
