PACKET.TRANSPORT.TCP(1)packet.transport.tcp 1.0.1 PACKET.TRANSPORT.TCP(1)NAMEpacket.transport.tcp - TCP module
DESCRIPTION
Decode TCP layer.
CLASSES
class TCP(baseobj.BaseObj, packet.unpack.Unpack)
TCP object
Usage:
from packet.transport.tcp import TCP
x = TCP(pktt, buffer)
Object definition:
TCP(
src_port = int,
dst_port = int,
seq_number = int,
seq = int, # relative sequence number
ack_number = int,
hl = int,
header_size = int,
window_size = int,
checksum = int,
urgent_ptr = int,
flags_raw = int, # raw flags
flags = Flags(
FIN = int,
SYN = int,
RST = int,
PSH = int,
ACK = int,
URG = int,
ECE = int,
CWR = int,
),
options = string, # raw data of TCP options if available
data = string, # raw data of payload if unable to decode )
Methods defined here:
---------------------
__init__(self, pktt, data)
Constructor
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 con‐
densed:
'TCP 708 -> 2049, seq: 3294175829, ack: 3395739041, ACK,FIN'
If set to 2 the representation of the object also includes the
length of payload and a little bit more verbose:
'src port 708 -> dst port 2049, seq: 3294175829, ack:
3395739041, len: 0, flags: ACK,FIN'
