view story

http://www.backtrack-linux.org – Hi, I'm using metasploit on bt5r3 everything is working fine... I'm was just thinking about would the "metasploit browser autopwn" still function if I used a no ip account and just forwarded the port on my router to my internal IP address... does anyone now? I did google around and did not find anything related.... Thanks in advance! Adam (HowTos)
