Sorry Chris, but maybe i wasn't enough clear in my description. You're right but let me give you more detail.
Each Vlan is on a floor and on each floor there is a SW Nortel 420 connected in fiber to the Nortel 8006. Some Ibm hub are connected to the SW Nortel 420. We're going to investigate the mirroring function. But i'm not sure we could mirroring 6 Vlan in one port. I'll try to install second nick on Ntop server. Thank for your support. K. ------------------- I think for your first question you answered your own question: "Core Switch (Nortel 8006) is installed on VLAN 1" If your switch is only on VLAN 1, you'll only see VLAN 1 traffic on it. To see all six, you need to hook up to a switch that is carrying all six VLANs and then mirror all six VLANs to the port that you'll attach Ntop to. Your second question: my guess (purely a guess with no more info) is that you only have one NIC in that machine and that NIC is attached to a mirrored port that does not accept two-way traffic (typical). Add a second NIC - one for "sniffing", one for management. Make sure the machine can communicate with the rest of the network, then worry about Ntop.

Well, I've got 6 VLAN's 1- 192.168.0.0/24 2- 192.168.2.0/23 3- 192.168.4.0/23 4- 192.168.6.0/23 5- 192.168.8.0/23 6- 192.168.10.0/23 Core Switch (Nortel 8006) is installed on VLAN 1 and my server "Fedora Core 5" with Ntop is connected to Core Switch >From each Vlan i can ping address to another Vlan. But when i use Ntop i can capture only all traffic in 192.168.0.0/24 Even if i use option -m 192.168.4.0/23 i have only result from 192.168.0.0/24. I try to change net/mask from interface....same result as before. My second problem (less important), i can only access to web interface from local computer. Even on the same Vlan it is not working Thanks for your help.
