I'm trying to verify a use case of NetFlow Analyzer.
Installed and having up and running netFlow Analyzer on an Linux server.
Now, trying to export flow to the listener on port 9996, but here I'm failing somehere.
I'm trying to export flow from the same Linux Ubuntu server Eth interface linked to a hub, through softflowd solution which is also the same server where NetFlow Analyzer is installed.
I'm using command softflowd -i MYINTERFACE -n MYIP:9996 as a standaone command
I've also gone through export flow GUI which pass ok through all steps:
A) Enter IP of source device
B) Enter the User Name, Password, Prompt, Enable Command, Enable User Name, Enable Password, and Enable Prompt.
test the connection using Ping, Test SNMP, or Test Telnet/SSH are all Passed.
C) Select Interface page, select the Loopback interface
D) Export Flow page, since NetFlow Analyzer doesn't have predefined flow export commands for this particular device model, I manually enter the commands and execute them using NetFlow Analyzer's CLI or GUI. (i.e. softflowd -i MYINTERFACE -n MYIP:9996)
E) when I press Close button, the device is not added.
Is it possible to use Ubuntu as an export flow source (which is actually exporting, as the "softflowctl statistics" is reporting:

if not, would it be possible to export from a Huawei DN8245F router eventually , on which I've lesser authonomy though, so wouldn't be the peferred solution.
