    And, on the off chance a Frenchman takes offence, threaten them with violence. They'll surrender before you're even finished.

    I know I'm sounding like a broken record, but in case you haven't guessed, this will only work if the search is not encrypted. If the user is logged in, it will be encrypted, and this keyword filter will be rendered ineffective.

    Yeah we have blocked the kids logging into google, by blocking the URL spat out when you click log in, so that should fix it, LGFL are offering nothing other than a 'Well pfft we block waht we block, you have to just deal with it' attitude so we are looking into an additional firewall.

    This is why I whitelist TLS. I only allow TLS if I've added it to my exception list. Originally I'd done this to stop proxy bypass sites. but the google encrypted fits, I'm just glad they changed the URL!


    btw porn and boobie is as daring as I get in edugeek, think ruder and body parts and actions in french, spanish, etc!

    Just to let people know LGFL have admitted that the key words that are listed in the ''Global and RBC Keywords'' Only apply to the following web sites: Google, Yahoo, MetaCrawler, Live Search, Excite, Lycos, AOL Search, Dog Pile, Hot Bot, Bing, Ask, YouTube.

    So any students can go to another search engine and type in a keyword listed and gain access to any of the images.

    Hi

    The filtering system in LGfL 2.0 is a bit on the complex side as it’s grown over the years – previous school I was at had WebScreen 1 and the LGfL system is WebScreen 2.0 when I asked this was because of the complexity of all the required solutions that people wanted and asked for have been rolled into the product so it has zillions of buttons. X13 is right just block the login page but this will not help with other Google services you might want to gain access to. Theres also a dozen of other tricks you can apply to restrict access to google and other sites like key words and such like. Best thing I did was go on a WebScreen training course at Atomwide which was free – have you done this ? if not it will help you out but to get fine control on the filter system needs careful setup on your part. The alternative is to have an aggressive filter but you then need to live with the other sites it will block – course it doesn’t help that google and all the other search engines want to let everything through anyway. Sorting via dns does work but again hampers progress in other areas. I believe in general all the filter systems suffer this feature set. Decrypting ssl – would do the trick but that’s a whole other ball game – imagine a fraud on a bank site that you have un-packed the ssl and wrapped it back up with an error in it …..

    If you have a local firewall you will need to configure it so it’s worth tweaking the WebScreen II set up first before shelling out on another firewall – with another firewall I’m not convinced you will be that much better off.

    When we were an RBC school we never used the filtering, we always did it in house with a squid/squidguard filter.

    that way we could adapt and react quickly when needed.


    The RBC actualy has some code credited for squid (long time ago)

    and way way back I was asked (with a few other techs) by the fledgling RBC to look at deploying squid in some primary schools , we fired out some boxes to them with squid on old PC's connected to their ISDN2.... Couple of years later CrashPilots were being rolled out.


    Filtering is impossible to get even close to 100% right , especialy as ISP where each customer may have very different requirements.

    Even as an I.T. Support department it's tricky keeping everyone happy ( or unhappy ) all the time.


    what seriously does not help is staff allowing kids to play java games on dodgy websites.....

    Bumping this with another problem.

    If you use IE it does not allow the searching of xxx or porn
    If you use Firefox it allows some pictures but not loads
    Using Google Chrome is a lot worse. If you do, do it out of site of students

    I will be speaking to other schools tomorrow and getting back to support with my findings.

    Thanks @RJohnson91 I'm surprised that you haven't had a heap of thanks for posting this up.

    I'm also wondering if anyone in other Regions has succeeded with the information you posted up with getting round the Grid Filters? I just added the various suggestions that the responses so far have generated to our filter as sure as eggs are out of chickens rear ends our little dears will have been trying.

    This is more a informative post rather than a question or query to LGFL.

    For the past 2 months now I have been battling with LGFL over 'raise an issue' about our kids being able to access porn under the LGFL filtering.

    Now you may think that your school is completely safe, for your own piece of mind do the following test (obviously under student filtering, in an environment of which kids cant see your screen)

    Go to google images, and search 'computers' in the normal search an let google display the results, now click images. Once google has displayed the images type in something 15 year old boys would think of 'Girls naked'. Now at this point google will step in with THEIR filtering, not displaying the images. Now if you click sign in, at the top right, Once signed in you can remove the google filtering and watch as the NSFW images roll in. (Obviously some images wont display because of the website they are being pulled from is indeed blocked, but scroll through some pages..)

    Solution to the above is block the URL that google is producing when you click sign in, perfectly fine, but what about the other 2,000,000,000,000 search engines with little to no safe search filtering.

    We also found that going to other search engines, we could type in the word PORN, yes as blatant as PORN and with the relaxed filtering display over 900 pages of XXX images, remember that this could be done at ANY primary school / secondary under the LGFL filtering.

    Please do some tests for yourself.

    As mentioned above we have had a case open for almost 2 months now, and LGFL are chucking us round in circles. We have had the same low level support engineer for the past 2 months, and we are getting nowhere. Apparently the 'developers' are going to get involved. Hmm.

    So I pose to you, is this because they donít have a clue about the problem, or is it because they know they have a major issue, and are telling this 'smaller techies' to just 'fob us off' whilst they hide???

    just wondering what sorts of results you get if you use the portable apps versions of different web browsers such as Firefox, opera etc. not sure if they do IE or chrome as portable apps??
