Dear Sir, Thank you for your fast reply, so is there is a site that I can download a version of ntop for windows that is not restricted to this small number of packets? Please advice.

Dear Sir, I am having a problem with ntop and I hope that you could tell me the reason for it. I work in a major ISP in Egypt and I was interested in discovering the amount of bandwidth consumed by P2P application in the internet traffic of the users in my network using ntop. I am deploying the windows version of ntop (ntop-3.1-demo) on a Dell machine, as a sample I configured port mirroring on an interface on a juniper router that carries the Internet traffic of some of my customers. I used port mirroring on the interface of the juniper M5 router to mirror the internet traffic of the customers and send it to the server that hosts the ntop application. The problem is that the ntop has indicated that almost 80 % of the traffic was http traffic and almost no P2P traffic that belongs to any application was detected. Theses results were very strange as I did that test at the very early morning where most of the customers are asleep so I expected to see most of the traffic as a P2P download sessions. So I have 2 possibilities, either my idea about the traffic types on my network was greatly mistaken (in this case our network will be the first network in the world that has no problems with the P2P trafficJ), or that something went wrong that prevented the ntop application from identifying the traffic of the P2P applications like kazaa and bit torrentetc. I hope that you can provide me with an advice about the reason why didnt the ntop detect the P2P traffic, and if I can do something about that or not.

RE: [Ntop] I am having a problem, ntop doesn't detect P2P traffic. could you advice me what to do ?
How about LOOKING at SourceForge? We don't mind helping people - but it's self help - and we DO expect you to have at least LOOKED at the resources that are already available first... docs/FAQ: Q. What's the scoop with ntop on Windows? A. Semi-officially, ntop for Windows 95/98/ME/NT/2K is also provided as a binary application with limited capture capability (1000 packets). This is intended to allow demonstration of ntop for people without access to a Unix system. We call this version Win32 after the old official name of the Windows library. If you want to use the full version with unlimited packet capture you can either: * Recompile ntop from the source by yourself (Luca says just open the files in MS Visual C++ 6.0 and press compile) * Register your ntop for Windows 95/98/NT/2K copy by paying a convenience fee to receive the prebuilt executable. If you decide to register your copy, Luca will send you an URL from which you can download the full version periodically. -Burton -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ramy Motawei Sent: Thursday, December 29, 2005 9:40 AM To: ntop@Unipi.IT Cc: Mohamed Gamal Subject: RE: [Ntop] I am having a problem,ntop doesn't detect P2P traffic. could you advice me what to do ?
