#Reads a pcap file into python using scapy and produces a csv file as output in the following format: Timestamp, source MAC address, source IP address, Destination MAC address, Destination IP address

#modular design, which makes it easy to include this source into another program, or to extend this one

from scapy.all import *

def main():

pcap_path = raw_input('Path of pcap file: ') # enter the path where you stored the pcap file

file_path = raw_input('Enter target file name') #enter the path where you want to create a csv file

process(pcap_path, file_path)

def process(pcap_path, file_path):

try:

file = open(file_path+'.csv','w') #tries to opens the file in read mode

pkts = rdpcap(pcap_path) #inbuilt function of scapy to read pcap files

for i in range(len(pkts)):

if ARP in pkts[i]: #checks if the packet is an ARP packet or not

file.write('%d,%s,%s,%s,%s,%d,%s\n'%( pkts[i].time, pkts[i].hwsrc, pkts[i].psrc, pkts[i].hwdst, pkts[i].pdst, pkts[i].op))

print 'file write complete'
