Hi Everyone,

I need to do some security scans and test and have therefore installed BackTrack4 in a KVM in proxmox. Some of the things I need to do requires wifi and for that I have installed an usb ALFA AWUS036H nic.

I have the nic installed in proxmox using the aircrack-ng driver and patch. The nic is up an running just fine on the proxmox host and is identified as wlan1. Directly from proxmox I am able to scan for networks etc, but now comes my question.

How do i make a bridge on wlan1 so that I can use the wireless nic from my backTrack? I have tried creating a bridge device from the proxmox web interface but when I try to save it with wlan1 as "Bridge Ports" it says "Error: unable to bridge device 'wlan1'".

Why cant I use wlan1 as a bridged device when I can use an eth device?

If someone have any suggestions on how I get the wifi nic to be visible to my BackTrack it would be greately appreciated.

Thanks.
 
you should rename wlan0 to ethX, I have three wlan devices successfully renamed to ethX :D
 
Thanks, that got me a step further :)

I have changed wlan1 to eth1 in the file "/etc/udev/rules.d/70-persistent-net.rules" so now the wlan1 displays as eth1 in proxmox and it still functions as a wireless nic. I am also able to create a new bridge on eth1. So I created a new bridge, but no matter what model I choose when I add ethernet device to my BackTrack, it shows as a regular cabled nic in BacTrack.

When I do a iwconfig it says
eth0 no wireless extensions.

I guess that means that I have to setup the wireless connection form proxmox to be able to get any conneciton in my vm?

But that is not entirely what I wanted. Is it possible to add the bridge to my BackTrack vm and still have it shown as a wireless nic in BackTrack so that I can use the aircrack-ng functionality in BackTrack?

So basically what I want is to be able to use the nic as a wireless nic in my vm BackTrack.
