I have a 12 port Cisco switch spanned for 4 ports looking at the internet connection. Different applications all needing to see this traffic. You can always use a hub to test this with.
Yes my ntop machine is on the same subnet as my firewall. -----Original Message----- From: Chyka, Robert [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 25, 2008 7:06 PM To: NT System Admin Issues Subject: RE: Looking for packet shaping/viewer appliance/sotware What if your router is your firewall too ? Do you span the port that the router plugs into the core switch and run ntop on that spanned port? Do I give the ntop machine a ip address on the same subnet as the router ethernet port?

I have ntop running on a vm/XP machine. I catch high usage people all the time. This very simple and free program will show you immediately who's talking. -----Original Message----- From: Kurt Buff [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 25, 2008 6:55 PM To: NT System Admin Issues Subject: Re: Looking for packet shaping/viewer appliance/sotware If all you're looking to do is see bandwidth usage by protocol, and other monitoring tasks, such as who your top 3 talkers are, etc., I can heartily recommend putting up a *nix box on a mirror/span port on the switch to which your firewall is connected, and running ntop. ntop is really dang cool - http://www.ntop.org/overfview.html On Tue, Nov 25, 2008 at 12:26 PM, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > At one of my clients we have the need to try and determine how the internet > is being utilized.
