Good evening all,
Recently, i have installed on a virtual machine (VMWare), this beautiful linux version with the scope of cracking my personal wifi with WEP key using a usb wifi adapter with the rtl8187b chipset.
I tried many drivers, but no one seems to work "correctly"; when I do iwconfig wlan0mode monitoring, it puts the adapter in monitoring mode, then if I do ifconfig wlan0 up it takes a bit of time, but it accept it; instead, when i launch the driver scipt ./wlan0up it gaves me these errorsi
insmod: error inserting "ieee80211_crypt-rtl.ko": -1 File exists
insmod: error inserting "ieee80211_crypt_wep-rtl.ko": -1 File exists
insmod: error inserting "ieee80211_crypt_tkip-rtl.ko": -1 File exists
insmod: error inserting "ieee80211_crypt_ccmp-rtl.ko": -1 File exists
insmod: error inserting "ieee80211-rtl.ko": -1 File exists
insmod: error inserting "r8187.ko": -1 File exists

I've tried to go on anyway: I've opened a new console and i've done all the process from airodump-ng until aireplay, when I arrive at the command aireplay-ng -1 0 -a(the bssid) wlan0, it have given me "Sending authentication request) (open system) and it repeats it more times until "attack was unsuccessfull" plus the possible causes. I've tried everyting, but it doesn't work.
Can anyone help me?
thanks to all in advance and sorry for my bad english
