    Question ettercap -eth0 works, atheros works, ALFA Rtl8187 Problems

    Equipment involved: BT3B HDD install, Ethernet (eth0) Atheros PCI Card (ath0) and ALFA RTL8187 (wlan0)

    Good morning members i am new to the work of ettercap but enjoying the learning curve im currently surfing (credit to yeehaw and other members involved).

    i am currently using the GUI version to get familiar with the commands.
    Unified sniffing & arp poisoning
    Firt i try a wired connection...
    i tested eth0 for the arp poisoning and managed to capture passwords via my wireless desktop (on xp). hotmail and ebay no problem, certificate popped up etc.

    So then i decided to try my wirless devices for the posioning.....
    Firstly my Atheros PCI
    i selected my ath0 device (listed in my sig) and same fantastic results.....
    then i disconnect the atheros (from my network)

    I then went and setup my Alfa rtl8187 re-ran ettercap and started the poisoning and the returned to my desktop XP machine. Upon entering my hotmail details the login fails, no certificate warning pops up the login just fails (through firefox and opera and ie)("Page cannot be displayed etc") the same results for any Secure Logins (tested hotmail, Thunderbird(mail wont send), ebay, msn messenger.)

    Why does this occur, i never ran ettercap in BT2 so i have nothing to compare to really. Obviously running the BT3 Beta at the moment.
    my BT3 HDD is default, i have not patched or upgraded/changed any drivers or files only installed tcpreplay 2.3.5 since the HDD install.

    Thanks for showing your interest guys, and hope the information may help you to help me and others who may experience or seek the same information.

    ok after playing with it for a few days i tried different combinations, such as:
    (nothing to do with drivers etc, i left all SOFTWARE RELATED topics well alone) booting up with it plugged in, not plugged in etc.



    Anyway i had to power up WITHOUT THE ALFA PLUGGED IN
    With that done i associated with my AP using the iwconfig wlan0 essid ETC key ETC


    started ettercap (GUI version) and voila, ARP-poisoning worked.

    sometimes if i use addition devices BEFORE my alfa in ettercap, such as my ath0 and eth0 before using my alfa (testing all devices here, normally i would only use the one device of course) then the alfa would not poison.

    I hope this is clear but i thought it may help or possibly just point out slight problems.

    The main reason for this post was to test the alfa along side other equipment within backtrack 3(b) and ettercap.

    Thanks

    Its cool that you gave feedback on how you got around to fixing this. Not a lot of members come back to tell us how they fixed it.

    Although, I have an Atheros and a RT73 [Edimax]. I usually enter this command: 'ifconfig ath0 down' , then I take down rausb0, change the mac and then 'ifconfig rausb0 up' . You can start B|T with both cards in, as far as I am concerned anyway.
