We have a network with a lot of users and they all connect through a few firewalls to get to the internet. The very first firewall that is hit has WIndows XP installed on it. When I run MS Network monitor, I can see all the packets going out with their source IPs.
I am looking for an OpenSource network monitor that can tell me who is hogging the bandwith, what sites people are connecting to and possible even stop downloads if they are hogging too much.
I was reading that one of the cooler features of Orion Networks' network monitoring app was that, you can drill down and if someone is downloading, you could block that particular download. I guess it's a session based thing, no idea.
I would prefer not to have to install clients on every machine but, for the capability, I will.
Anyone know of anything? I am looking to not have to spend any money ;)
