Captured packets contain enough information to identify the operating system. In contrast to active scanners such as nmap and QueSO, p0f does not send anything to the host being identified."

If you can narrow down the parameters of your question (eg: I have a network of windows machines and I'd like to figure out exact versions on each one) then you might have more luck. Hi Jan,Edd Perhaps you mean something like: p0f-2.0.3|/usr/ports/net-mgmt/p0f|/usr/local|Passive OS fingerprinting tool|/usr/ports/net-mgmt/p0f/pkg-descr|[EMAIL PROTECTED]|net-mgmt|||http://www.stearns.org/p0f/ Which was written by William Stearns (if you read this bill, HI!), and now maintained by Michal Zalewski (lcamtuf).
