dpkt throws NeedData on valid pcap
Question: I have this python code:

    
    
    import sys
    import dpkt
    
    f = file("pcaop.Pcap")
    pcap = dpkt.pcap.Reader(f)
    
    i = 0
    for ts, buf in pcap:
        print "Ya"
    

dpkt throws NeedData on the 52nd packet. The same one every time - I've
checked packet 52 and it is the same as everyone else on wireshark.

What causes this?


Answer: Solution is provided here: [Python stops reading file using
read](http://stackoverflow.com/questions/8440819/python-stops-reading-file-
using-read) I had the same problem when dpkt.pcap was working fine under Linux
but failed instantly when run in Windows. The problem is that when a file is
opened in text mode `open("filename", "r")` the file is read until EOF is
encountered. Thus, `open("filename", "rb")`
