Passive OS fingerprinting utility
'p0f2' is a versatile passive OS fingerprinting utility, to be used for evidence or information gathering on servers, firewalls, IDSes, and honeypots, for pen-testing, or just for fun. It is a complete rewrite of p0f version 1 that used to be maintained by William Stearns. 'P0f' is useful for gathering profiling information about your users and customers or attackers (IDS, honeypot, firewall), for active or passive policy enforcement (restricting access for certain systems or otherwise handling them differently), and for content optimization, pen-testing, and thru-firewall fingerprinting, as well as the tasks for which active fingerprinting is not suitable.
