# The security/p0f3 port

## p0f3-3.09b – passive OS fingerprinting tool

## Description

    P0f is a tool that utilizes an array of sophisticated, purely passive
    traffic fingerprinting mechanisms to identify the players behind any
    incidental TCP/IP communications (often as little as a single normal SYN)
    without interfering in any way. Version 3 is a complete rewrite of the
    original codebase, incorporating a significant number of improvements to
    network-level fingerprinting, and introducing the ability to reason about
    application-level payloads (e.g., HTTP).

    The tool can be operated in the foreground or as a daemon, and offers a
    simple real-time API (via unix domain sockets) for third-party components
    that wish to obtain additional information about the actors they are
    talking to.
