    Default Wireless problems

    Greetings!
    I been hanging around BT a while, and decided to install it.
    It went successfully. But there is one thing that annoys me, I cant get my wireless device in monitor mode.
    After googeling a bit I found out that this card wasn't supported by default.
    Suddenly I don't have the driver which is required for packet injections.
    I did indeed found some posts on the forum, but it was BT2, now I was just wondering if anyone knows if this is fixed, or something?
    Is there anyway I can get this working? Would be much appreciated

    Code:
    bt ~ # iwconfig
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wmaster0  no wireless extensions.

    It says clearly in the second part of the code that you will need to download and install iw. Which also means you will need to compile before installing.

    Indeed, but if I am remembering right I got some kind of kernel issue last time.

    What hatake_kakashi was saying about compiling is that when you download iw.tar.bz2 it will need unpacking and then compiling.

    i think it will also need so extra librarys/files for this installation.

    if you google "installing iw.tar.bz2" this should help

    You can download the iw program at the bottom of the following link:

    hxxp://aircrack-ng.org/doku.php?id=mac80211

    Make sure you install libnl 1.0pre8 or above from Gslapt/slapt-get or compile from sources before installing iw. Even with iw compiled you most likely will get another error message. I recompiled my iwl3945 drivers with the latest mac80211 subsystem and I got this message.

    Code:
    bt ~ # airmon-ng start wlan0
    
    
    Interface       Chipset         Driver
    
    wlan0           Intel 3945 a/b/g        iwl3945 - [phy0]nl80211 not found.
    mon0: ERROR while getting interface flags: No such device
    
                                    (monitor mode enabled on mon0)
    
    bt ~ #
    After doing a little research nl80211 is removed from mac80211 for kernels 2.6.23 and earlier. So, I'm assuming even with the iwl4965 drivers and software in place, then you won't be able to get your card into monitor mode. Even though, it says monitor mode is enabled from above, my card still isn't in monitor mode and mon0 doesn't exist. There drivers for iwl4965 and iwl3945 are still in early development but there has been some developtment on the drivers to get fragmentation to work with patches. Here is a link with some development work that is being done on both of those drivers.

    Not sure if this helps any but this is what I've found so far. The IPWRAW drivers seem to be a bit buggy and I'm waiting for the injection to start working on the IWL drivers.

    Any updates on the Intel 4965 on BackTrack 3 Final, will injection work, which drivers if any work?

    I can't specifically say that iwl4965 fully supports injection but they do say that there is limited success. I don't own the 4965 card, but I recently upgraded my kernel to 2.6.25.9 and added the patches for my iwl3945 card. Seems to be working, but I haven't fully tested it out. The aircrack-ng website has updated information on the current state of the driver.

    you know, if you google "installing iw.tar.bz2" the only results, is linking to this site xD

    But, since I am on holiday with my family, bored to life.
    I will check out if I can get the iwl4965 to work. There are someone ho is reporting success and failure.
    But there is one thing thats is a must, you must have the => 2.6.25.x kernel.
    And the BT3 live cd comes with 2.6.21.5. So you have to use HD installed BT, or maybe USB will work. Anyways, you have to be able to upgrade your kernel.
    Pureh@te was so nice that he posted this link...
    hxxp://forums.remote-exploit.org/showpost.php?p=79341
    on how to upgrade your kernel.

    Then afterwards you can follow the
    hxxp://aircrack-ng.org/doku.php?id=iwl4965

    If I get it working, I will tell you guys how I did it.
