PACKET.PKT(1)packet.pkt 1.0.1 PACKET.PKT(1)NAMEpacket.pkt - Pkt module
DESCRIPTION
Provides the object for a packet and the string representation of the
packet. This object has an attribute for each of the layers in the
packet so each layer can be accessed directly instead of going through
each layer. To access the nfs layer object you can use 'x.nfs' instead
of using 'x.ethernet.ip.tcp.rpc.nfs' which would very cumbersome to
use. Also, since NFS can be used with either TCP or UDP it would be
harder to to access the nfs object independently or the protocol.
Packet object attributes:
Pkt(
record = Record information (frame number, etc.)
ethernet = ETHERNET II (RFC 894) object
ip = IPv4 object
tcp = TCP object
rpc = RPC object
nfs = NFS object
)
CLASSES

Usage:
from packet.pkt import Pkt
x = Pkt()

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 is condensed into a
single line. It contains, the frame number, IP source and des‐
tination and/or the last layer:
'1 0.386615 192.168.0.62 -> 192.168.0.17 TCP 2049 -> 708,
seq: 3395733180, ack: 3294169773, ACK,SYN'
'5 0.530957 00:0c:29:54:09:ef -> ff:ff:ff:ff:ff:ff, type:
0x806'
'19 0.434370 192.168.0.17 -> 192.168.0.62 NFS v4 COMPOUND4
call SEQUENCE;PUTFH;GETATTR'
If set to 2 the representation of the object is a line for each
layer:
'Pkt(
RECORD: frame 19 @ 0.434370 secs, 238 bytes on wire,
238 bytes captured
ETHERNET: 00:0c:29:54:09:ef -> e4:ce:8f:58:9f:f4, type:

IP: 192.168.0.17 -> 192.168.0.62, protocol:
