How to change the order of the network cards on Ubuntu
My brand new Ubuntu 12.04 install assigned PCI network card as "eth0" and motherboards integrated network device as "eth1" by default. The problem is I want to use the integrated device as default (eth0) network interface. I already edited : Step 1 : Vi /etc/udev/rules.d/70-persistent-net.rules Step 2 : delete old PCI network card Name Step 3 : Changed Eth1 to Eth0 To swap the names and everything seems to be ok and network is working but programs are still trying to use the PCI network card (which is now "eth1") as the default in terface. For example iftop now tries to use "eth1" as default device as it used "eth0" before the swap.
