Ubuntu 11 10 aireplay ng and the mon0 is on channel 1 error and how to fix it shell script included

I had recently upgrade my Ubuntu install to 11.10. Along with other annoyances I came across I ran into a bit of a deal breaker when I went to run aireplay-ng. I was getting the following error:


This was going to be a huge problem since I know that my ZyDAS 1211 chip set was compatible with packet injection. After searching around for a bit I found a great solution from this site here about the drivers and how to patch and reinstall the older ones back in. Below I have a script that you can run to get that installed.

Tutorial AirCrack Ng

Bem,para come�ar esse tutorial foi baseado no Linux Ubuntu.

Ser� necessario ter o pacote aircrack ent�o,abra uma nova shell e digite "apt-get install aircrack-ng" *Sem as aspas*.

Espere o download ser concluido e vamos por a m�o na massa.

Digite sudo su [enter]
Depois digite sua senha para ter acesso root :D

airmon-ng stop wlan0 < Aqui vai desativar o dispositivo.

Apos parar o dispositivo d�:

ifconfig wlan0 down < Com esse comando ira resetar as configura��es.

em seguida use o:

macchanger --mac 00:11:22:33:44:55 wlan0 < Para mudar o MAC da sua placa de rede.

airmon-ng start wlan0 < Para ativar a placa de rede novamente

Se der certo vai aparecer (Mode monitor Enabled) .

Ma mesma shell digite este comando,

airodump-ng wlan0 airodump-ng -c (Aqui digite o canal da rede) -w (Digite aqui o nome do arquivo que ira ser criado com os pacotes) --bssid (BSSID da rede) wlan0


Ir� aparecer uma tabela, com uns numeros subindo (o DATA), � a quantidade de IVs capturados.
Voc� precisara de mais ou menos 80 Mil a 120 Mil IVs para conseguir quebrar uma chave WEP
Isso demora, depende do nivel do sinal da rede, depende do tanto de pessoas utilizando aquela rede, e depende da potencia do dispositivo que voc� usa.

Ap�s ter um numero considerados de IV , sem fechar a shell antiga abra uma nova e digite

aircrack-ng -b (BSSID) (Aqui � o nome do arquivo que voc� escolheu,se foi "teste" digite teste-01.cap)

Ficando assim

aircrack-ng -b (BSSID) teste-01.cap

Agora � s� aguardar a chave ser quebrada :*

Se aparecer 32:54:69:85:74:12
A Chave sera 325469857412 no windows e no linux ser� 32:54:69:85:74:12

Quase esqueci,se voc� n�o tiver o MAC Changer d�

apt-get install macchanger para instalar


Se n�o conseguir com aqueles comandos tente esses :

ifconfig wlan0 down
.
iwconfig wlan0 mode monitor
.
airodump-ng wlan0
