Hopefully someone can assist my ignorance in regards
to using NTOP as a NetFlow collector.  If not ...
thats cool!  Just thought I would ask.  I just have a
few basic questions, which are listed below after I
describe my environment.

My environment explained;

Questions:
----------

1) I have 2 options when switching NIC's; eth0 and
NetFLow-device.  Im assuming eth1 (which is the
monitoring port) is labeled NetFlow-device because
since NetFlow is enabled ... it is the interface which
can export NetFLow to another collector.  However, my
question is what interface should I select to view
NetFLow data received from the router I am sending
NetFlow data?  eth0 (ip 10.4.4.51)?

2) Say for instance you are only using NTOP to view
NetFlow data received from a router.  What & where
would you see NetFlow data presented in NTOP?  Im
assuming I will not see sessions because NetFlow data
are sessions which have ended?  It seems like I should
see everything else however it appears as though I am
only seeing broadcasts NTOP is able to pickup off that
port on the switch (and me connecting to it via 80 and
22).  Hopefully I explained this so that you can
understand my question.
