    Question Aircrack on ubuntu help?

    ive installed aircrack suite with no problem, i put my card in monitor mode no problem useing airmon and when i type airodump-ng eth1 i get the following error:

    root@laptop-blud:/home/elliot# airodump-ng eth1
    ioctl(SIOCSIWMODE) failed: Invalid argument

    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 eth1 <#>'
    Sysfs injection support was not found either.
    and i know my card is compatable because aircrack works with with bt3

    im also using the same wireless card to access the internet so i know that the drivers are working

    It can take a lot of trial and error to successfully use aircrack. A lot of it depends on which wireless chipset you have too - there are a few excellent ones that are always recommended. I would advise you check your chipset against aircrack's lists to see how compatible (or not) it is. Common advice is to buy one of the better ones first.

    I really struggled to get my Broadcom BCM4401-B0 working (driver iwl3945). In the end, whilst I had small successes, I figured it would be a better use of my time to buy a better wireless NIC.

    I would advise reading through http://ubuntuforums.org/showthread.php?t=528276 and also the official documentation.

    Have you successfully changed channels yet?

    Is it possible to GUI aircrack-ng?

    Just gave my setup another go... after running

    Code:
    sudo airmon-ng start wlan0
    I got my monitor interface (mon0) back again:

    Code:
    ace@ace5:~$ ifconfig
    mon0      Link encap:UNSPEC  HWaddr 00-13-02-D3-FD-A1-30-30-00-00-00-00-00-00-00-00  
              UP BROADCAST NOTRAILERS RUNNING PROMISC ALLMULTI  MTU:1500  Metric:1
              RX packets:12867 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000 
              RX bytes:2039740 (2.0 MB)  TX bytes:0 (0.0 B)
    
    wlan0     Link encap:Ethernet  HWaddr 00:13:02:d3:fd:a1  
              inet addr:192.168.1.115  Bcast:192.168.1.255  Mask:255.255.255.0
              inet6 addr: fe80::213:2ff:fed3:fda1/64 Scope:Link
              UP BROADCAST RUNNING  MTU:1500  Metric:1
              RX packets:4619302 errors:0 dropped:0 overruns:0 frame:0
              TX packets:3211691 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000 
              RX bytes:2323981992 (2.3 GB)  TX bytes:309827168 (309.8 MB)
    [... etc ...]
    wlan0 is my actual wireless interface
    mon0 is the promiscuous interface created (by the aircrack-ng start command)

    Then running

    Code:
    sudo airodump-ng mon0
    pulls everything up correctly. You're trying to do this with eth1, which is not correctly set to promiscuous mode or anything else - which is why you're getting "expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM". You need to check the documentation and get the first step working - getting your ADDITIONAL monitor interface, much like my mon0.

    edit: to do useful things you'll probably have to change channels too. I just recommend properly reading the documentation at http://www.aircrack-ng.org/doku.php

    I don't think there is a GUI for it.
