warlord asked:

I am looking for software that can track the websites and webpages a user has visited. For example, I am operating a wireless router that connects 5-7 users to the Internet. I am interested in what are these people are doing with my wireless service, as in are they abusing the wireless service that I am providing to them?

I am interested in how much time they are spending on the Internet, what websites they have visited or the webpages they are surfing and if they are downloading materials.

I know that such software are available on the open market but so far, I’m not sure where to find them. I am hoping for examples of such software that I can use.

Furthermore, I also wonder if the users on my wireless router can block such tracking software or If they can tack my attempts to follow them or if they will be aware if I am using such software to track them.

I undertsand that large networks and corporations routinely use such software. Are such software very expensive?
