Hey everyone !

I am using Backtrack 5 Gnome 32 bit version and I've successfully tested the DNS spoofing with ettercap among with the Social Engineering Toolkit. I watched a video in youtube explaining all the process.

When a user from my LAN accesses http://www.twitter.com and tries to login, the login fails and I'm able to get its username and password information, however the user is redirected to the same false twitter.com page.

How can I redirect the user to the real twitter.com page after that first login in which I'm able to get its login data? I would have to change that dns mapping because the twitter.com url is associated to my backtract 5 linux machine. How can I change that dns mapping back to the default/real one?

Thank you so much !
