You probably have NTOP on a switched network, and are missing some of the traffic. The 
way I get around this is to place a hub between the backbone/regular network, with 
NTOP listening there. 
 
Switched network --->Hub w/NTOP box ---> Backbone/server switches
 
or I also do it this way
 
Switched network --> Hub w/NTOP --> Router -->Remote Router ---> Hub w/NTOP --> Remote 
switched network
 
 
I am sure that email will mangle my beautiful diagrams...oh well. You should be able 
to get the idea. You can also use port mirroring. I have these hubs placed like this 
for sniffing/analysis anyway (but this is a test lab, not a production environment)

Subject: [Ntop] Question (probably dumb) from a new user




Good morning.  I just started using NTOP to monitor my network this week, and so far 
its going well, but I have a question. 

According to my summary screen, NTop has been running for 1 day and 20 hours and 
change.  So  it is showing total packets processed at just over 207,000 I know that's 
a large number, but it doesn't seem like enough for what Ive been doing on the 
network.  We have about 100 regular users who are logging in etc, as well as I did 2 
ghost casts yesterday, (each one over 5 gigs).  Does NTOP only sample every so often, 
or is my traffic really that low? Or am I totally messed up?

Thanks

TIM
