eth0 interface in VirtualBox (Backtrack 5 VM)Posted: 5 March 2012
After generating a new MAC address for a virtual NIC, I had two interfaces: the loopback interface (
eth0 had disappeared, and
eth3 wasn’t getting assigned an IP.
It turns out that
udev on Debian assigns a new
eth number for each new MAC address. Deleting the file
/etc/udev/rules.d/70-persistent-cd.rules solved this problem.
