Hi everybody! I'm from Brazil and new at this Forum. I work in IT in a High School that's have a Macbook to each student, and Wi-Fi for all, now we upgrade our internet link, but now we need to block access for certains web sites such as megaupload, rapidshare, torrents and etc. How 2 Mac OS Servers 10.6.4, anyone have an idea to block these sites and downloads of torrents? Thanks for now.
