Hello, everybody.
I am using the netflow data recently.But I have found a question as follows:
The tcp flag is always zero no matter what the netflow is. I print the
content of netflow with the program flow-print. For about 200,000 real netflow
(All of them are tcp flow),there is not one flow with a non-zero tcpflag.
What is the matter? I use the flow-print and run it as follows:
./flow-print -f1< netflowdata
Does anyone can help me?Thanks very much.
Best wishes to all
