good day to all,i have been searching for months/weeks/days and always given up on trying to install sslstrip! first of all i understand it is already in backtrack just not installed? ive been reading up about various scripts etc to use but only after sslstrip is installed..and there lies my problem!!!

im am running bt5r3 from an sd card with no updates etc just a fresh copy downloaded and dumped as iso on card i open terminal and enter

/pentest/web/sslstrip which then tells me its a folder,so from what ive read i then type ./ install which then goes on to tell me no such directory?
if someone would be so kind as to post how i can set about installing i would be very much appreciative of you,
