I'm capturing network traffic with pypcap and writing it to a file with dpkt. Problem is I can't delete the file as I get an error saying it's still in use by another process.
seconds = 15
starttime = datetime.datetime.now()
pc = pcap.pcap()
file = open('file.pcap', 'wb')
pcapfile dpkt.pcap.Writer(file)
for timestamp, packet in pc:
currenttime = datetime.datetime.now()
timedelta = currenttime - starttime
if timedelta.seconds > seconds:
break
pcapfile.writepkt(packet,timestamp)
file.close
time.sleep(10)
os.remove(file.pcap) = file in use by another process error
I'm currently overwriting the pcap file the next time I capture traffic. Doing this overwrites the file data most of the time, but occasionally it doesn't work and I end up with a large pcap file encompassing two sets of network capture data.
How do you close the pcapy/dpkt process handle?
Also does anyone know a better way to stop pcapy capturing traffic after 15 seconds?
Thanks
