    Metadata details:
    filename: memcached_udp_version.rb
    path of file: ./repos/metasploit-framework/modules/auxiliary/scanner/memcached
    
    the code of the file until where you have to start completion: ##

    @memcached_probe ||= [
      rand(2**16), # random request ID
      0, # sequence number
      1, # number of datagrams in this sequence
      0, # reserved; must be 0
      "version\r\n"
    ].pack("nnnna*")
