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.
Emphatic Nonsense 
Delete /etc/udev/rules.d/70-persistent-net.rules worked for me.
it works .. thanks alot
Can u pls tel me how to connect backtrack installed in Virtualbox to wireless network .??? appreciate it 🙂
@Harsha, the easiest will be to attach an external USB wireless adapter. For example, products by ALFA: http://www.alfa.com.tw/products_show.php?pc=34&ps=21
Then, enable the USB controller and enable a device filter, as shown in this screenshot:
