I'm running ntopng v. 1.2.1 (r8157)  - fantastic product by the way!  Loads
of useful information, and invaluable for diagnosing network issues.

I'm noticing something odd however. I have historic flows turned on, (i.e.
--dump-flows) and as I view the hosts according to throughput or total
bytes, I see the traffic direction is often listed incorrectly. I've ran
numerous tests to determine how consistent this is. When an internal hosts
downloads a ~2GB file from an external internet server, the flow is
recorded as the internal host "sending" rather than "receiving". Every way
you could read this flow shows the same thing: that the internal host is
"sending" 2GB of data.

I'm just curious why the flow would be presented that way. In cases of
diagnostics, this could be very misleading.

Thanks in advance for your help,
NeilPage
