aircrack-ng wpa-o1.cap -w /desktop/wap.txt is where you are messing up
Its Desktop first of alll and you need to either specify the complete path which would be /root/Desktop/wpa.txt or you can use the ~ symbol which signifies the users home directory which you are running under which in backtracks case is root. so -w ~/Desktop/wpa.txt
Obviously you need to change wpa.txt with whatever the file name is.


Ive done the wep and wpa handshake on my network so far with no problem i think im looking to hard now at this easy problem and cant see the wood through the trees as to say.
