Possibly, you may want to access each elements by names in the
first line?

  data = []
  open(file) do |f|
    foo = Struct.new(nil, *f.gets.chomp.split(","))
    f.each do |line|
      bar = foo.new(*line.chomp.split(","))
      data[bar.num.to_i] = bar
    end
  end

  p data[1].date   # => "28Dec2001"
  p data[2].action # => "drop"
  p data[3].iface  # => "eth-s1p1c0"
