    Scanning

    I have a question about scanning.
    When ever I scan with nmap, I get results that all ports are filtered.
    I scaned more than 100 IP adresses and didn't found 1 open port. Thees adresses wasn't from some security specialists, but from ordinary people usually running xp sp2 (most of them not updated) and windows 2003 server.

    So this ports are filtered because thy are behind firewall.
    But what to do now ???? How to bypass this ?
    When ever I see this tutorials, thy all find open ports, but this is very hard to find.

    So what to do now, you can't attack filtered ports with exploits, or do you ?

    You have permission to scan these machines...right

    If you cant find the open ports...I would say the firewall is doing its job well.

    Not sure why you want to bypass....or attack filtered ports???

    You can use this command line:
    --open: Only show open (or possibly open) ports
