First, thanks for the quick answer and sorry for not giving all the details. Finnally, I got it to work and I'll give some explanations below. The dual homed linux is NAT-ing the private network of our University. It is where ntop is running, it's a Mandrake 8.0 on a PIII-600MHz/256 RAM/SCSI U2W machine. Since our NAT policy is rather complex and I won't discuss it here, there are multiple addresses (aliases) on each NIC. So I configured the ntop and the collector to use the private segment (10.xx..) to transfer data. Everything worked very well, but the data files were containing no data, as I said. Finnaly, after some tcpdumping on the interfaces I noticed that the udp packets were sent through another IP address than I was expecting. After configuring the collector to accept packets from that address, everything started to work (as I am now writing some special scripts to get what I want from the flows..) That's about it. Is there any parameter to set to tell ntop which interface/ip address to use when exporting the flows? Anyway, thank you very much for that work, I really appreciate it!!
