New Installation Help Needed
Hello,

Fresh install of ntopng and nprobe on CentOS, install from the CentOS repos. Version details below. Per the documentation, I run:

ntopng -i tcp://127.0.0.1:5556
nprobe --collector-port 6343 --zmq "tcp://127.0.0.1:5556"

When I run nprobe in verbose mode, it reports receiving good flow data with numerous messages like this one:
19/May/2016 11:26:17 [engine.c:2361] New Flow: [tcp] 10.x.x.x:7101 -> 10.y.y.y:49550 [00:00:00:00:00:00 -> 00:00:00:00:00:00][vlan 1234][tos 2][ifIdx: 1000001 -> 18][subflowId: 0/0x0000][idx=124586]

But when I stop the nprobe process, it reports that it is not processing any flows, and there is no data in NTOP ("No packet has been received yet on interface tcp://127.0.0.1:5556"):

19/May/2016 11:26:24 [nprobe.c:2457] Processed packets: 107 (max bucket search: 1)

19/May/2016 11:26:24 [nprobe.c:4967] nProbe terminated.

What am I missing? I have tried to dump the inbound packets using -dump-pkts capture.pcap, but Wireshark reports that the resulting file is corrupt.

Thanks in advance,
Dennis
