Re: How to determine that the Snort is ready to capture the traffic?

[Andrey Kiryukhin <andrei_1980 () mail ru>]

I know it's bad practice, but i experiment with snort in undefined for
me network (i have only ip range). Unfortunately, i can not scan or do
other  active things.
So, for first  step, i decide init all available rules  and   suppress 
the ones that give a lot of false positives. 

For next step i plan use passive "scanner" like p0f (and other) do
determine home net structure  and tune snort rules.

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are 
consuming the most bandwidth. Provides multi-vendor support for NetFlow, 
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
reports. http://pubads.g.doubleclick.net/gampad/clk?id=1444514421&iu=/41014381
