Will an nmap Operating System scan work through a firewall?

2006-07-28T00:12:58Z

From the mailbag, Jesse C. writes: I have been assigned a project within my organization to perform OS Fingerprinting on subnets. What I find is that end-users that do not use Windows Firewall (have it disabled or not installed), I am able to detect their OS with no problem. The problem lies that many new users have Windows SP2 Firewall enabled which are limiting my scan results. I am using the following nmap command in Linux. (# nmap -sS -O -PI 192.168.0.1/24) What should I do to accurately perform an OS Fingerprint scan on my subnet? If not 100% accurate, what nmap commands would your suggest?
