packet.pkt

PACKET.PKT(1)							 packet.pkt 1.0.1						     PACKET.PKT(1)

NAME

       packet.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

   class Pkt(baseobj.BaseObj)
       Packet object

       Usage:
	   from packet.pkt import Pkt

	   x = Pkt()

       Methods defined here:
       ---------------------

       __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 is condensed into a single line.  It contains, the frame number, IP source and destination 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: 0x800(IPv4)
		       IP:	 192.168.0.17 -> 192.168.0.62, protocol: 6(TCP), len: 224
		       TCP:	 src port 708 -> dst port 2049, seq: 3294170673, ack: 3395734137, len: 172, flags: ACK,PSH
		       RPC:	 CALL(0), program: 100003, version: 4, procedure: 1, xid: 0x1437d3d5
		       NFS:	 COMPOUND4args(tag='', minorversion=1, argarray=[nfs_argop4(argop=OP_SEQUENCE, ...), ...])
		   )'
