packet.record — Record module


Provides the object for a record and the string representation of the record in a tcpdump trace file.


class Record(baseobj.BaseObj)

Record object

    from packet.record import Record

    x = Record(pktt, data)

Object definition:

    frame       = int,   # Frame number
    index       = int,   # Packet number
    seconds     = int,   # Seconds
    usecs       = int,   # Microseconds
    length_inc  = int,   # Number of bytes included in trace
    length_orig = int,   # Number of bytes in packet
    secs        = float, # Absolute seconds including microseconds
    rsecs       = float, # Seconds relative to first packet

Methods defined here:

__init__(self, pktt, data)

Initialize object's private data.

pktt: Packet trace object (packet.pktt.Pktt) so this layer has access to the parent layers. data: Raw packet data for this layer.

__str__(self) String representation of object The representation depends on the verbose level set by debug_repr(). If set to 0 the generic object representation is returned. If set to 1 the representation of the object is condensed to display either or both the frame or packet numbers and the timestamp:    '57 2014-03-16 13:42:56.530957 ' If set to 2 the representation of the object also includes the number of bytes on the wire, number of bytes captured and a little bit more

verbose: 'frame 57 @ 2014-03-16 13:42:56.530957, 42 bytes on wire, 42 packet bytes'
