the output of netstat -anp | grep 2055 was:
udp        0      0 0.0.0.0:2055            0.0.0.0:*                           -    
there is no pid!!

Run tcpdump and ensure the flows are making it to your ntop host.  If so, run "netstat -anp" and ensure there is is something listening on "your" netflow port: 2055, 2056, etc.  Then compare the pid listed to that of ntop and ensure they are the same.  Lastly you MUST "Admin" -> "switch NIC" and choose your netflow NIC.
