Dear All,
I am currently attempting to accomplish a project in which NTOP plays a key
role. However much about what I need for NTOP seems a little vague in this
regard. It has been already more than a month since the start of my project
and I really really need help already. My project is something to replace
MRTG with something similar... the current MRTG configuration in my office
was designed to monitor network bandwidth on the firewall and router's
interfaces. We wanted to have more information on the graphs and and so I
thought NTOP may have an answer for this if it works. Information such as
HTTP usage, SMTP usage, etc etc segregated among the interfaces of the
firewall and routers.
I already compiled NTOP and had the machine connected a hub where the
internal firewall interface is located. However, the graphs were absolutely
empty even though I tweaked the protoUsage.pl to check dumpData.html for the
IP interface of the firewall. I also tried configuring the libpcap filtering
expression but all my attempts in using "gateway" expression failed. I'm
currently using Windows2000.
So my question is: Can NTOP track packets going through the interfaces of
the firewall/routers and have RRD tool graph them by protocol even when the
NTOP was installed in a different machine? If so, am I missing something?

p.s. If the project is successful, I'll be glad to support your group for
furthering your research with NTOP. ;)
