PacketFu::Write

Write 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, as working with PacketFu::PcapFile directly is generally going to be more rewarding.

Public Class Methods

a2f(args={}) click to toggle source
Alias for: array_to_file
append(args={}) click to toggle source

Shorthand method for appending to a file. Also shouldn't use.

# File lib/packetfu/pcap.rb, line 598
def append(args={})
  array_to_file(args.merge(:append => true))
end
array_to_file(args={}) click to toggle source

array_to_file is a largely deprecated function for writing arrays of pcaps to a file. Use PcapFile#array_to_file instead.

# File lib/packetfu/pcap.rb, line 569
def array_to_file(args={})
  filename = args[:filename] || args[:file] || args[:out] || :nowrite
  arr = args[:arr] || args[:array] || []
  ts = args[:ts] || args[:timestamp] || args[:time_stamp] || Time.now.to_f
  ts_inc = args[:ts_inc] || args[:timestamp_increment] || args[:time_stamp_increment]
  byte_order = args[:byte_order] || args[:byteorder] || args[:endian] || args[:endianness] || :little
  append = args[:append]
  Read.set_byte_order(byte_order) if [:big, :little].include? byte_order
  pf = PcapFile.new
  pf.array_to_file(:endian => PacketFu.instance_variable_get(:@byte_order),
                   :arr => arr,
                   :ts => ts,
                   :ts_inc => ts_inc)
  if filename && filename != :nowrite
    if append
      pf.append(filename)
    else
      pf.write(filename)
    end
    return [filename,pf.to_s.size,arr.size,ts,ts_inc]
  else
    return [nil,pf.to_s.size,arr.size,ts,ts_inc]
  end

end
Also aliased as: a2f
format_packets(args={}) click to toggle source

format_packets: Pretty much totally deprecated.

# File lib/packetfu/pcap.rb, line 556
def format_packets(args={})
  arr = args[:arr] || args[:array] || []
  ts = args[:ts] || args[:timestamp] || Time.now.to_i
  ts_inc = args[:ts_inc] || args[:timestamp_increment]
  pkts = PcapFile.new.array_to_file(:endian => PacketFu.instance_variable_get(:@byte_order),
                                    :arr => arr,
                                    :ts => ts,
                                    :ts_inc => ts_inc)
  pkts.body
end
