    Web Filtering

    Our county uses Surf Control to block the naughty web sites etc.

    Unfortunalty you can still search google(and google images) and see words and thumbnails that are unsuitable.

    I have a head teacher who is unhappy as while searching "welsh dragons cartoon pictures" in google came across some sites advertising porn/sex etc.

    The sites were blocked but you could still see the Blurb about the sites i.e."cum here to see naked fcuk pics" etc etc.

    Anyone use any soft that prevents sites with these words from being displayed ?

    Or can someone recommend a Child safe search engine ?

    Thanks

    Hi. I'd recommend setting up your own filtering proxy server. IPCop linux with Advanced Proxy Server and URL Filter addons make for a good, solid and free (open source) proxy server.

    Re: Web Filtering

    Below is an e-mail I received from Google which I think may help with regards to searching on Google...

    As you can imagine, filtering in an automated way is quite difficult.
    It is very difficult to write a program that can catch all offensive
    webpages and pictures. On the flip side, with 4 billion documents
    and 1 billion images, we cannot use human editors to find offensive
    content. Thus, our filter is not perfect.

    The safest setting that Google has is "Strict filtering" which can be
    turned on through our preferences page:
    http://www.google.com/preferences?hl=en
    If you select Strict filtering here you will get a very strict filter.
    Sadly, a lot of the relevant pictures are also filtered when this is
    in use, and it occasionally lessens the quality of our results.

    While this filter is not password-protected, it is somewhat of a chore
    to turn it on and off, so hopefully this will discourage deactivation
    of the filter by the children.

    Alternatively, if your school deploys a proxy on your web traffic, it
    may be possible to configure your proxy to append "&safe=strict" to
    all requests to images.google.com. This will cause strict safesearch
    to be used regardless of the preferences page setting. Check with
    your school's IT administrator to see if this is possible.

    As for a list of Google urls, I recommend you to look at our list of
    domains we offer Google in - http://www.google.com/language_tools?hl=en.

    I would like to apprise you that Google is currently researching an
    image search product that might be more suitable for schoolage
    children.

    Sincerely,
    Karen Padham
    Product Manager, Google.com

    Our provider uses this, which does indeed mean that changing the options via the google page have no effect. Have a word with your ISP pooley.

    Re: Web Filtering

    If you have a little linux skill then you can build yourself a good box with squid, Dansguardian and Squid Guard and maybe ClamAV as well but Ive not tested that yet. If your not too good with Linux I would recommend Censornet which is a Linux distro that is easy to install and use and will provide you with all the filtering you need.
    If you want to do your own box I have some very rough notes on building a box under Debian.

    Dansguardian will filter out nastyness from google image search quite happily. Just include the 'googlesearch' wordlist in your blacklistedwords config file.

    Re: Web Filtering

    Thanks for the info guys.

    Google strict search is a good option - but going around 100+ pc's and manually setting it up (possibly for every user) isnt really an option.

    Never played with linux at all. :?

    but will try and get my hands on a pc tomorrow and install linux - and learn on the fly lol.

    Cant ask ISP as isp is county borough - admin and Curriculum sides seperate etc.

    Schools have become a poor cousin.

    Cheers

    Re: Web Filtering

    Here in Powys Pooley we also have Surf Control. Filtering is a big issue with individual schools, and a few have gone there own way using methods suggested above.

    Powys have banned words within google searches, and enforce safesearch settings, both using Surf Control.

    I would challenge other posters that no method is entirely safe. Indeed, we decided here in Powys that if we took on filtering locally we also take the legal responsibility. Our 'official' statement is that we do everything reasonably possible to block innapropriate content.

    We feel the same as you pooley about our relationship with the county. But we do take our responsibility seriously and play our part in keeping the filter as good as we can.

    You can always add on to the system with an additional level of filtering you control, like censornet. Only don't remove yourselves from the loop making the service for all schools worse.

    Re: Web Filtering

    To be fair im not looking to alienate myself from county - but surfcontrol is not good enough for what the teachers want.

    We have enforced safe search etc, and each school in the county can set their own filtering options, also bad words are filtered (so no searching for sex etc) but after a few pages in google/yahoo you get some sites come through anyway.

    Going to have a little play with censornet.

    Also going to try and find a way to enforce Strict filtering in google, but on a global scale.

    Re: Web Filtering

    You can enforce strict search with Squidguard by rewriting the urls. I posted a ruleset a little while ago for ChrisH. I'll attempt to find it.

    Re: Web Filtering

    I have just chucked out our ISA2000/N2H2 Filtering and replaced it with:

    Smoothwall 2.0
    Dansguardian
    Clam Anti Virus
    Advanced Proxy Filter
    Advanced URL Filter

    and as a result NOTHING (well almost) gets through, it has made my life SOOOOOO much easier in this area.

    Best of all its free and only took 2-3 hours to get up and running 1 day to fully configure and 1 week of solid out of hours testing.

    {edit}
    did i mention the fully featured web frontend to the whole thing

    Re: Web Filtering

    I can't recommend Smoothwall enough.

    Once you get into Modding version 2.0 with all the addons it becomes incredibly powerful. With my smoothwall images like you mentioned are blocked with its bannedphraselist section which blocks...ermmm... phrases on the list like below.

    ,,
    ,<&safe=off>


    Anyone who takes safe search or family filter off cannot do a search using google or altavista.

    I am very green when it comes to Linux but I got it up and running and its really interesting.... I even learnt a few things.
