I need help for hacking my lan network, from where our ISP provide internet in our area. we use internet from our Lan by loging in through username/password. They monitor our network through MAC address only. I used cain & able to poising the main machine and i got succeed but i dont know how, only one time i succeed, but now i m not getting any username/password and MAC of others. Or any idea so that i can use internet without loging into their network(BGBPPPoE). Any one can help by suggesting any useful software or any other tricks.
