    We are using Websense, main purpose is to control web traffic and block people to download large files. But it's too expensive, we are thinking about alternatives, we only need to block some significant sites like drag, adult, etc, no need to advance, and limit people to download large files, any other choices for me? I just wonder if I bulid a Linux proxy would do what I need? Thanks!!

    No problem, let me explain what Websense / Surfcontrol did:
    Websense have divided websites intro many category, for eg,
    http://www.sex.com will be inside ADULT category,
    in Windows AD, we can assign HR DEPT not able to see ADULT, GAMBLING but only can see HR related sites, so whenever they open ADULT sites, a blocking msg will be displayed instead. We can recategory website to another category also.

    Therefore, the category database should be updated frequently as the number of web site change over time.

    In Websense, it can block protocol based traffic too like IM.

    So I wonder if Linux's web filter solution works similar or as least can do what we want--block some pre-defined bad web sites, and we can define what web site is good or bad

    I think this tutorial is interesting for you: http://www.howtoforge.com/debian_ebox

    eBox comes with a web interface that allows you to sepcify finetuned filter rules for the Squid web proxy.

    falko! I tried the ebox system and it's really an amazing system, but I want to view more statistics about SQUID... how to monitor the cache ratio hits on squid for example...

    thank you for all your support

    Regards,
