Read is largely deprecated. It was current in PacketFu 0.2.0, but isn’t all that useful in 0.3.0 and beyond. Expect it to go away completely by version 1.0. So, the main use of this class is to learn how to do exactly the same things using the PcapFile object.

file_to_array(args={})

A wrapper for PcapFile#file_to_array, but only returns the array. Actually using the PcapFile object is going to be more useful.

                                filename = args[:filename] || args[:file] || args[:out]
                                raise ArgumentError, "Need a :filename in string form to read from." if (filename.nil? || filename.class != String)
                                PcapFile.new.file_to_array(args)
                        end
get_byte_order(pcap_file)

Reads the magic string of a pcap file, and determines if it’s :little or :big endian.

                        def get_byte_order(pcap_file)
                                byte_order = ((pcap_file[0,4] == PcapHeader::MAGIC_LITTLE) ? :little : :big)
                                return byte_order
                        end
set_byte_order(byte_order)

set_byte_order is pretty much totally deprecated.

                                return true
                        end
