I'm using Pcapy and impacket module for packet sniffer.
I'm able to capture the whole data in a variable and display it.
I want extract the IP addresses , Port no's and Payload data into separate variable and display it.
code is as follows:
-
import sys
-
import string
-
from threading import Thread
-
-
import pcapy
-
from pcapy import findalldevs, open_live
-
import impacket
-
from impacket.ImpactDecoder import EthDecoder, LinuxSLLDecoder
-
-
-
class DecoderThread(Thread):
-
def __init__(self, pcapObj):
-
datalink = pcapObj.datalink()
-
if pcapy.DLT_EN10MB == datalink:
-
self.decoder = EthDecoder()
-
elif pcapy.DLT_LINUX_SLL == datalink:
-
self.decoder = LinuxSLLDecoder()
-
else:
-
raise Exception("Datalink type not supported: " % datalink)
-
-
self.pcap = pcapObj
-
Thread.__init__(self)
-
-
def run(self):
-
self.pcap.loop(0, self.packetHandler)
-
-
def packetHandler(self, hdr, data):
-
d = self.decoder.decode(data)
-
print d
-
-
def main(filter):
-
dev = 'eth0'
-
p = open_live(dev, 1500, 0, 100)
-
p.setfilter(filter)
-
print "Listening on %s: net=%s, mask=%s, linktype=%d" % (dev, p.getnet(), p.getmask(), p.datalink())
-
DecoderThread(p).start()
-
-
filter=' '
-
main(filter)
How can i do that....
Thanks....
