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: xdh_x_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/multi/misc
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: https://metasploit.com/download

          This module allows remote command execution on an IRC Bot developed by xdh.
          This perl bot was caught by Conor Patrick with his shellshock honeypot server
          and is categorized by Markus Zanke as an fBot (Fire & Forget - DDoS Bot). Matt
          Thayer also found this script which has a description of LinuxNet perlbot.

          The bot answers only based on the servername and nickname in the IRC message
          which is configured on the perl script thus you need to be an operator on the IRC
          network to spoof it and in order to exploit this bot or have at least the same ip
          to the config.
