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.

Subject: [Ntop] Vlan Report
Hello,
I've got 2 problems with Ntop and impossible to find the
solution....Maybe
here (i hope so).
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.
K.
