Owh...

I get it now...So means after i select which AP to crack and after i input the:

(Ch) (Ap Mac) (filename)

I just wait or De-authenticate...correct?

So once i i see the handshake...Then i can start bruteforcing it...

ill test it right away...hehehe...

Update:
I just tested disconnecting and reconnecting my lappie...i somehow do not see the handshake notification...btw my router now using wpa/wpa2.

oh yea...and the Mac to deauthenticate...the connected mac is at the bottom of the screen rite?

Thank you...

as for the cannot mkdir..is the folder already there??? I think i got the same error last time....but at the end i check my folder..its already created...Try check if the folder is already created or not...

Instead of creating the folder from X-term you can also manually create it at the file manager right?
