I am having an issue
obtaining network statistics in a WAN using ntop. I have obtained and
installed the ntop-3.0-Win32-demo.exe executable. I am able to connect to
the ntop application via the web interface however I don't obtain any network
statistics. I keep seeing a "No entries to display (yet)" on the various
webpages. The Hosts tab does not display any of the hosts on my
WAN including the laptop that I installed ntop on. This seems odd to
me. The network load page does provide a graph of
activity however.
My network
configuration is as follows:
I have a WAN consisting of 3 routers
(EtherFast�
Cable/DSL Router with 4-Port Switch) tied into a switch.
/--------\

|

| /-----------\
+--------| PC
w/ntop |
\-----------/
The
IP and host name of each machine on the WAN has been put into the hosts table of
PCs (since I have no DNS server). I have connectivity (can ping) each node
in the network either by name or by IP.
Do
you have any idea why ntop does not see packets from the other machines?
Why don't the any hosts populate in the hosts table? I am very excited to
use this tool. It seems to be a very powerful tool once I get the
configuration down. Any help you can provide would be greatly
appreciated.
Thanks in advance,
Keith
