NMapwin

What does "All ports scanned are: Filtered" mean? Is that a good thing or not?
and it stated something about to many fingerprints?

'All ports scanned are filtered' means exactly what it says, your target computer filters incoming packets based on certain criteria for all ports. Depending on how the firewall at the target computer's end is configured its probably a good thing (assuming you're testing out how secure it is).

Too many possible fingerprints afaik means it can't determine the OS of the target computer, because the computer fits too many of its OS fingerprints.

From where can i download this prog?

Have you tried the program's website? www.nmap.com
Or just go here to download it http://www.insecure.org/nmap/nmap_download.html . :killcompu

ii-monk: get nmap for linux, it is much more stable than the windows version.

Thanks begki. I know that linux are more stable than windows generally.

:D spread the word

i will do it.

Yeah I definitely suggest the Linux version. I have nothing but problems with windows when I use Nmap.
