Hi,
I have a wireless router connecting both windows and linux systems at home. I've discovered someone has been downloading illegal content on my network simply because they accidentally left the torrent downloader on their screen when showing me something. I removed their access for a few days as a punishment and told them never to do it again or I'd disconnect them permanently. I've just discovered by similiar means that they are still doing it. I can't trust them to obey the rules but I don't want to blanket ban them.
How can I monitor and log network web address accessing to my linux system? I know people are gonna shout hacker and other other dictator type comments but really I'm just trying to stop illegal activity on MY home internet network, I can't trust them, they've proven that, but I'm gonna get more grief if I remove their access and I'm not letting it carry on.
Thanks.
