[Flow-tools] Netflow TCP flag,help me ,please.

[lijian]

Hi,  I am using the Netflow to studying the Network security. I want to get the TCP flag feature of Netflow data, but it always is zero. I have already known that it due to the certain type of cisco router. But I can't replace the router. I want to use a software to get the data in Netflow format. 
    What a pity, I have tested NetflowExporter,softflowd in a Linux os. But the TCP flag is also zero. Is there any software for unix/linux which can make the TCP flag not zero? 
    Is there any netflow data available in the Internet? 
    Thanks very much.
    Merry Christmas and Happy New Year.
