Usage:
      ownlan --[options] [sub-options] --[other-option]

Example:
      ownlan --attack client --target-ip 192.168.0.1 --interface eth0 --delay 0

where [options] are either:

where [sub-options] are either:

Attacks sub-options:
  client              Set a First-Duplex disconnection attack (the client is targeted). If no source mac argument, yours will be given (useful for MITM Attacks).
                      * Required options: victim_ip
                      * Falcultative options: random_mac , source_mac
  gateway             Set a Second-Duplex disconnection attack (the gateway is targeted). If no source mac argument, yours will be given (useful for MITM Attacks).
                      * Required options: victim_ip
                      * Falcultative options: random_mac , source_mac
  ntoa                The client is targeted to get disconnected, using a neighbour table overflow attack. Requires a victim ip.
                      * Required options: victim_ip
                      * Falcultative options: random_mac
  fake-ip-conflict    Generate a fake ip conflict to the victim. Can be used along all the others attacks, or alone.
                      * Required options: victim_ip

# Protect part
banner <<-EOS

Protect sub-options:
  stealth          Becomes invisible from network scanners, preventing you from getting targeted.
  static           Set a static ARP Cache for the current session. Good against first-duplex ARP Cache Poisoning.
  freeze           Reset and Freeze your ARP Cache. Good against NTOAs.
  resynchronize    Operate a dual duplex attack on a victim to disconnect the attacker and heal the victim. Warning: If you are the victim, you will have to fill the optional options.
                   * Required options: victim_ip
                   * Optional options: victim_mac , gateway_mac

  EOS

# Broadcast part

Broadcast:        Send raw ARP packets to the wire.
                  * Required Options : victim_ip, victim_mac, source_ip, source_mac
