Hi
i find this great script wich could work full automatic and collect handshakes from Wifi networks.
After some edit and install few packges from opkg im run this on pineapple :)
Maybe someone could this improve for Pineapple (sometimes i get some strange information etc. anyway script work 100% ok)
and make from this addon/plugin.
