as i said earlier sir i kno little about linux. yamas includes dsniff and dsniff has many sniffing files like filesnarf, urlsnarf, dnsspoof etc. i kno how to use yamas and what each filesnarff and urlsnarf does.. i got really surprised by seeing what yamas could do. i want to do the following like someone will type www.facebook.com and will automatically redirect to www.google.com bt the name on address bar will be facebook.com. i saw it on a video in youtube.also is it possible to kill other people who are sharing the wifi to get the full bandwith.its possible in android by wifikill application. hope to get support.
