[Ntop] ntopng installation

[Ali Kanarya]

First of all I would like to thanks about the great software.

Nowadays I am giving a try to ntopng to monitor our internet usage.
I am monitoring Draytek 2860 mirrored port.
I have 2 nics on my windows pc. One is directly connected to the
mirrored port, and the other one
is connected to another switch on LAN backbone.
Both nics are in the same IP subnet range. I need this because monitored
port is also monitored by draytek app on the same pc and this app
requires this.
I can monitor the port without problem using ntopng.

My question is that I cannot connect the ntopng web server through
another pc on LAN, because of nic IP issue.
On the monitoring pc, web server is accesible. I have to assign
webserver to the other nic in ntopng, i guess.

Another question, i didnt do enabling Promiscuous Mode on pc nic that
monitors mirrored port.
Is it necessary to do this?

Best Regards,
Ali

Hi Luca,

Thanks for your reply.
I will check the netstat.
For now, I handled the problem by redirecting port 3000 from one nic to other one in windows.

monitoring interface is directly connected to the draytek mirror port.
i understand from your explanation that monitoring interface wont be in the game of standard network traffic, if it is promiscuous, right?
i am also using wireshark, prtg and draytek smart monitor on this interface.
do you think that making promiscuous can unstable these apps?
I am asking this because I have no experince on promiscuous mode, sorry.

Best Regards,
Ali

Hi Ali
thanks for
contacting us.

The web
interface should bind to 0.0.0.0 so you should be able to
reach the GUI from all interfaces. Can you check with
“netstat” from cmd.exe if this is the case? I believe
that on the NIC you’re sending traffic to, you do not need
to set an IP address.

Promiscuous is necessary as ntopng needs to
capture packets not directed to the MAC address of the
monitoring NIC
