I have Ntop running with multiple interface (configuration: /usr/sbin/ntop -d -P /usr/share/ntop/ -u operator -E -n -i eth0,eth1,eth2,eth3,eth4 -L -c -M -p /usr/share/ntop/protocol.list) and most interfaces captures little to no data. I use eth5 for management / access to Ntop. I have tried all interfaces with and with out IP addresses. If I run a sniffer trace I see plenty of data on all the interfaces. Some interfaces report data but only layer 2 data.
The only interface the captures IP data is eth3, which is on the same subnet as my management / access to Ntop interface. I have tried the -j option (I am spanning or monitoring other ports) with no luck.
Any ideas why Ntop would not report the capture of data on different interfaces (I have performed the switch interface function from the admin screen)?
