Hi, my name is Ramón Reséndiz, from Monterrey, México, and i have some
doubts with the ntop monitoring.

 

When i see the Network Traffic [All Protocols]: All Hosts - Data
Sent+Received, i can see the hosts from the networks (2 networks with
netmask 24 bits), but also I can see records from some pages that I don’t
understand, like:

And according to me this host are pages visited from my users but for
unknown reason this appear like hosts in my network, ¿some one know why this
happens?

 

I have cisco switch 2960 divided into virtual lans (vlans), and all the
traffic are sent to the port where the pc with ntop have 2 network
interfaces where, ntop listen from linux interface eth0, and also I have
other network interface eth1 where I check for network status.

 

I’ll appreciate so much your help, thank you.
