This script is specially useful when you clone VMs, but can be used in any other kind of situation where you have problems with network cards, say, duplicated cards for X reason.
Try to run this script I wrote:
if [ $UID -ne 0 ] then echo "Sorry, you have to run this script as root" else cat /etc/udev/rules.d/70-persistent-net.rules | grep PCI | cut -d' ' -f5 | cut -b 2-6 | uniq > /tmp/drivers for driver in $(cat /tmp/drivers); do rm -rf /etc/udev/rules.d/70-persistent-net.rules && echo "Removing 70-persistent-net.rules" rmmod $driver && echo "Removing $driver" modprobe $driver && echo "Loading $driver" done echo "Done." rm -rf /tmp/drivers fi
Tested under Debian and Fedora, but should work fine on other distributions.
The code is also on my github
