NTOP will give you extremely granular information on your network in general. It may be above and beyond your requirements, but it can impress your powers-that-be. SNORT will most likely give you the control you need to present the information in a reasonable fashion. Although it seems to me you could simply run wireshark and post-process the dump in perl and present them the data. Scott -----Original Message----- From: Edward C.

I'm reading about SNORT and NTOP now and will choose one of them by today. Which one would you recommend if I need to log the following: 1. Timestamp 2. Source IP 3. Website visited These 3 are the vital ones but it's better of course if I can get other details. Edward
