eth0 interface in VirtualBox (Backtrack 5 VM)
Posted: 5 March 2012 Filed under: system administration | Tags: debian, networking, ubuntu, virtualbox 4 CommentsAfter generating a new MAC address for a virtual NIC, I had two interfaces: the loopback interface (lo
) and eth3
. 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.
