Hello,

I use ntop and it is a great tool to monitor your network.  First thing is that you need to set up port mirroring on your switches, or setup a passive hub.  I like to monitor the port where my router is plugged into so that I can see all the traffic coming in and out.  If you have linux, then you can go to this website, and find instructions on how to get it up and running:
http://www.ntop.org/

Unfortunately I only have Windows computers on my network so you have to find a Windows compiled version of ntop.  The site I originally got the compiled version from, OpenXtra, no longer supports it and took it down, so I have the file hosted here if you are interested:

Here are the instructions on how to install it:

When you find a site that comes up on your list on ntop, you can click on it, then it will show you the clients who are accessing it.  Normally it will be an IP address, or the computers name (it will not show the actual user logged onto the computer).

Also, You need to mirror the port that you are trying to monitor.  Example.  If your Gateway/Router is on port #1 on the switch, then you will need to have some other port (lets say port #2) monitor/mirror port #1.  You would then install ntop on a computer/laptop that is plugged into port #2 because he will now see all the traffic going to and from your Gateway/Router.  Here is a website that explains it a little more in detail:

I hope this information will get you pointed in the right direction & good luck!
