    Hi
    First of all thanks a lot for this tool..It was working till yesterday.. now today is a different story. I had been installing OpenCL on Backtrack and configuring it (ATI Radeon Card). Also installing pyrit which is not fully functional yet. Not sure if that broke Fern.

    Basically when I press for Scan for Access Points button I am now getting following message.

    "Fern failed to start scan due to an airodump-ng error: ioctl(SIOCSIWMODE) failed: Device or resource busy ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start wlan0 ' Sysfs injection support was not found either."

    Please note the versions as below:

    Python Version: 2.6.5 r265:79
    Aircrack Version: Aircrack-ng 1.1 r2076
    Qt Version: 4.7.3

    I am running BackTrack 5 R2 64 Bit Gnome.
    Linux bt 3.2.6 #1 SMP Fri Feb 17 10:34:20 EST 2012 x86_64 GNU/Linux.

    Thanks once again for this tool..
    regards

    thanks a lot for your reply..
    I somehow missed the pointer here I suppose. My driver is working fine and airmon-ng and all associated commands work ok. I can manually scan and dump all handshakes no problem. However am getting the aforementioned error while running FERN.

    This time I ran FERN and when I got the error: "Fern failed to start scan due to an airodump-ng error: ioctl(SIOCSIWMODE) failed: Device or resource busy ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start wlan0 ' Sysfs injection support was not found either." I opened a terminal and did this:

    root@bt:~# airmon-ng
    Code:
    Interface	Chipset		Driver
    
    mon0		Atheros AR9285	ath9k - [phy0]
    wlan0		Atheros AR9285	ath9k - [phy0]
    What am I missing please?

    Hi,

    First thanks a lot for your tool.
    Second I'm getting the exact same problem as hannah above. Checking out the Rtl8187 vs r8187 link didn't solve my problem.
    I can enable monitor mode no problem through airmon and fern used to work fine a few days ago so I think the updates to BT5 R2, aircrack and/or fern broke something.

    BT5 R2
    Fern 1.5
    Aircrack-ng 1.1

    As you can see, my Alfa USB card seems to be working fine with airmon directly. It's just fern that seems to trip up when enabling monitor mode.
    I think this is a bug.

    root@bt:~# airmon-ng


    Interface Chipset Driver

    mon0 Realtek RTL8187L rtl8187 - [phy0]
    wlan1 Realtek RTL8187L rtl8187 - [phy0]

    Also, dmesg shows following (that last "ADDRCONF(NETDEV_UP): wlan1: link is not ready" message looks suspicious)

    Hows the fix for my symlink problem coming?
    World Domination is such an ugly phrase. I prefer the term World Optimization.

    Yeah, same problem here. I think the problem is line 349 in fern.py:

    Code:
    mon_int1 = monitor_interface[-1]
    My output of airmon-ng is this:

    Code:
    root@bt:~# airmon-ng | egrep -e '^[a-z]{2,4}[0-9]'
    mon0		Realtek RTL8187L	rtl8187 - [phy0]
    wlan0		Realtek RTL8187L	rtl8187 - [phy0]
    The problem is mon_int1 is getting set to the end value i.e wlan0, whereas my Alfa lists mon0 as the first value. Editing line 349 to:

    Code:
    mon_int1 = monitor_interface[0]
    fixed it for me. If you want to try this then you'll need to delete fern.pyc before you rerun after editing fern.py, otherwise I'm sure Savioboyz will come with a more elegant solution.

    @Hannah, I can tell you that Atheros AR9285 drivers and Backtracks new 3.2.6 kernel has problems. One is with connecting to WEP. The other is if you create a soft AP with a dhcp3-server it will connect to it self on mon0. Ive read that it was fixed in kernel 3.2.6.1 but im not sure if you can up grade the kernel without breaking something.

    thanks a lot melissabubble. Funny that my whole Aircrack-ng suit works perfectly though.
    Appreciate your response.
