I downloaded some captures from the Sample Captures page tried reading it in wireshark through a pipe.
I reported "invalid libpcap format" error. But when i directly open the file using wireshark it reads fine. I dont 
understand why this happen? Isnt the file having the global header? 

I tried to do the same thing with my own capture file. This time it worked in both these methods. Could someone 
pls tell me why it is?
