  1. P0f is a tool that utilizes an array of sophisticated, purely passive
  2. traffic fingerprinting mechanisms to identify the players behind any
  3. incidental TCP/IP communications (often as little as a single normal SYN)
  4. without interfering in any way. Version 3 is a complete rewrite of the
  5. original codebase, incorporating a significant number of improvements to
  6. network-level fingerprinting, and introducing the ability to reason about
  7. application-level payloads (e.g., HTTP).
  8. The tool can be operated in the foreground or as a daemon, and offers a
  9. simple real-time API (via unix domain sockets) for third-party components
  10. that wish to obtain additional information about the actors they are
  11. talking to.
