If every port is showing up as filtered, that means the server isn't responding at all to your scans. If it's not responding, it doesn't seem like there's any way to get a OS fingerprint unless you find a way to make it respond.
All I can suggest is that you go down the list of scan types and try them all, see if anything works. If not, then you might be out of luck.

Hello everybody. When I try nmap -sS -P0 192.168.1.100 , I get the response all ports are filtered.The same result with -sW , or with -O I ´ve installed on 192.168.1.100 a PFW.But how can I get any information (OS, Service Pack) out, if even do not get any answer from the machine? Is there any trick or do I have forgotten something? Thx in advance --------------------------------- Do you Yahoo!? Read only the mail you want - Yahoo! Mail SpamGuard.
