Hi,
   
  Does some one know why the 
  following command: Tshark.exe r testfile.pcap q z 
  io,stat,30,COUNT(tcp.analysis.retransmission) tcp.analysis.retransmission 
  outputs this:
   
  C:\Program 
  Files\Wireshark>tshark.exe -r update.pcap -q -z 
  io,stat,30,COUNT(tcp.
  analysis.retransmission)cp.analysis.retransmission

  Instead of a column with the 
  counted tcp retransmissions?
   
  Got the same result with 
  :
  tshark.exe r testfile.pcap q z 
  io,stat,30,COUNT(tcp.analysis.retranmission)tcp.analysis.retransmission,AVG(tcp.window_size)tcp.window_size,MAX(tcp.window_size),MIN(tcp.window_size)tcp.window_size
I 
  am using TShark 1.1.3 (SVN Rev 27807) .
  (testfile.pcap does contain tcp 
  and retransmission so its not that)
   
  Kind 
  regards,
