Netflow Analyzer on Ubuntu 14.04 LTS issues

I've installed the analyzer on my Ubuntu box today, and everything appears to be working, except the web page is telling me "No device is currently exporting NetFlow / sFlow packets to NetFlow Analyzer". When doing a tcpdump on it, I'm seeing the traffic from my ASA:

11:47:55.674363 IP 192.168.5.254.43503 > Athlon64.9996: UDP, length 1388

Wireshark is showing them as CFLOW v9 packets

My data directory is empty, and its been running for several hours now. I've restarted the service a couple of times, and rebooted the server. The firewall on the server is disabled.

How do I verify the analyzer is actually listening for it ?

I'm not seeing any obvious signs in the logs of any issues.

Thanks.
