time and size of packet #134

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello,
i am new in python, and i need your help.
I am trying to get the time and size of each packet from a pcap file.
i tried the following:

f = open('test.pcap')
pcap = dpkt.pcap.Reader(f)
for ts, buf in pcap:
    print ts, len(buf)

but all i getting is some numbers, that are wrong comparing to the pcap in 
wireshark.
can someone help me???

Thanks

Try open with binary

f = open('test.pcap','rb')
pcap = dpkt.pcap.Reader(f)
for ts, buf in pcap:
    print ts, len(buf)

Could you please provide more details like the operating System and dpkt 
version?
Also, please upload the test pcap file that fails in comparison with wireshark.

Please see the following issues:

https://code.google.com/p/dpkt/issues/detail?id=27

If the timestamp values are not matching up with Wireshark, it is because of 
the way you are printing the value in python. See issue #129 for more details.
