      netsniff-ng is a free Linux networking toolkit. Its gain of performance
      is reached by zero-copy mechanisms, so that on packet reception and
      transmission the kernel does not need to copy packets from kernel space
      to user space and vice versa. The toolkit can be used for network
      development and analysis, debugging, auditing or network reconnaissance.
