[netflow-tools] flowd-reader export

[Murray Shields]

Is there any documentation on the export as generated by flowd-reader? 
For example, what are the possible values and meanings for proto (I know 
6 is TCP)? What is the most accurate way of matching bi-directional 
packets (is it simply a specific port number range)?

Can I simply assume that the LOWER port number is the port, and the 
higher is for matching?

I have tried all of the README files, installed documentation and 
Googled, but can find nothing on this. I have also grepped a downloaded 
copy of the mailing list archive.

Can anyone help?

Thanks.

Murray.
