    Which kind of scanner do you use?

    If you use nmap (linux) then it looks like nmap, if provided with a range of ports to be scanned (e.g. -p 100-1000), only shows the one that are open for real.
    If you scan for specific ports (e.g. -p 23,554,8080) then you get "filtered" if the port is not open.
