installed openvpn, now eth0 is dead

[u-995]

Hello,

Yesterday i installed these:

apt-get install network-manager-openvpn
apt-get install network-manager-openvpn-gnome
apt-get install network-manager-pptp
apt-get install network-manager-pptp-gnome
apt-get install network-manager-strongswan
apt-get install network-manager-vpnc
apt-get install network-manager-vpnc-gnome

But today I can't seem to get my eth0 back to work anymore... it doesn't do anything in wireshark neither... i can put it up and assign it an ip, but that's it... can't ping. I haven't done anything else with the vpn packages...

interfaces file:

# 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

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto

output ethtool eth0:
