    Re: Teachers!! - Setting up Broadband at home.

    Just another note with regard to proxies.

    If a manual proxy is set in internet explorer lan settings, as long as the "automatically detect settings" box is also checked, the internet should still work at home without the need to constantly turn the proxy on and off, automatic settings will win if no proxy is found.??

    This works for me anyway - I have no problems either at home or at school with these settings.

    Firefox however does still require you to manually switch the proxy on and off.

    i have used this script and it works well have done a few mods to it ie 4 settings 1 home 2 school proxy 3 staff unfiltered proxy They need to log int proxy to become unfiltered 4 no change. and the best thing is that thay still cant change proxy manually its still grayed out.

    so i am really happy now. just need to know how to shut a script down as it opens ie and does not shut down till ie is shut??

    thats normal with bat files, just do what i do and create a shortcut to it, and get the shortcut to make the cmd window the minimum size and hide it behind the startbar.

    so there is no way to force it to shut once it has opened explore.

    Re: Teachers!! - Setting up Broadband at home.

    We go for the they dont have any rights to install software on there Lappys at all. This can be a pain in the arse when it comes to broadband or standard internet connections that use dodgey installers. fine if its wireless but if they need to insall a adsl modem it can be a real bind. But overall it makes it alot easier to manage.

    At the end of the day its the Schools Laptop not the teachers!

    The other dreaded nause is that Bloody AOL!

    We are on the 50/50 route - they can do whatever they want with their laptops (as they have local admin) but they must have our site Anti Virus installed and active, they also must understand that if their wireless doesn't work at home but it works here at school - then we will help them but the priority is that the laptops work in school.

    If they want it to work at home more than school, then we disconnect it from the domain.

    The problem is the laptops (here at least) are considered as 'personal resources' - therefore we have to give them the ability to do anything with the laptops they may want - however if they break it - it might take a while to fix it back up

    For the staff who want to use Internet at home, we have showed them how to remove and replace to proxy settings for the school's network.

    They don't have any admin rights over their machine; they can't install software / run .exe's etc. and so far we've not had problems. However, we have had a few postitives in that staff have asked for things to be installed and we have said no, as it was nothing to do with school.

    As someone previously said, at the end of the day its the school's laptop, and it must work correctly in school by default. Teachers can't mess with settings that will make it not work when they return to school.

    To begin with, the SMT (mostly the head) was on the side of the teachers when they said they "should be able to do what they like" with their laptops. However, after the progress the school has seen since the technician and I started here 6 months ago, SMT have started to come over to our side now .

    This is why I've used a transparent proxy to filter our school internet connection - as far as teacher's laptops are concerned the school system works exactly the same way as their home wireless systems, they just can't visit any dodgy websites.

    VB 2005 prog I wrote to change between home and school internet access.

    Proxy Toggle

    This AutoIT script literally toggles the proxy on and off and reports which one is active, i nicked it off the AutoIT site ages ago. The teachers can understand this one. Ive seen less elegant solutions by other Techs at schools I have taken over the running of.

    Try it, you might like it.

    Code:
    $ProxyEnabled = RegRead('HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings','ProxyEnable')
    If $ProxyEnabled = 0 Then   
        RegWrite('HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings','ProxyEnable','REG_DWORD',1)
        MsgBox(0," Proxy Toggle","School Internet",2)
    Else
        RegWrite('HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings','ProxyEnable','REG_DWORD',0)
        MsgBox(0," Proxy Toggle","Home Internet",2)
    EndIf

    Teachers are paid enough to be able to afford their own computer at home. To be fair, most here do. However, we have some. One has no TV and uses the school laptop to watch dvds. She asks people to record her favourite programmes.

    I try and avoid letting the teachers access from home. Our last deputy head did and it seems his son used it mostly. I have spent forever removing gigabytes of music and dodgy images!

        MsgBox(0," Proxy Toggle","Home Internet",2)
    EndIf

    Is why I only give them one button to press and it tells them whats up.

    specifically page 6. Are they using the laptop for personal use on their personal internet?
    Just finding this now (a little late, I know!).

    Is this still the case that school-owned laptops used for personal work at home should be declared as tax assets? If so, how do people ensure/enforce a business-use-only policy?

    Also, how come personal use of a laptop at home is a no-no, but personal use of a desktop in school is okay?

    A useful thing to know about the BT Home Hubs is that you don't need the install CD at all to set it up. You can tell staff to follow the instructions for setting it up, ignoring anything to do with the BT software and plugging things into the laptop. BT pre-configures them with the right settings to connect to the internet. All the CD is there for it to install useless BT Yahoo junk (OK, not useless for the average person as it installs norton av/firewall etc which BT pay for in an attempt to keep most of their users from becoming spam spewing zombies, but not something you want with a managed install).

    The Home Hub by default has its wireless turned on and is secured with 64-bit WEP (not great, but better than the usual wide open). The Key is printed on the Hub itself, next to the serial number, iirc. All you need to do is add the staff's user account to the "Network Configuration Operators" group on the local machine to allow them to add wireless networks to the windows wireless networking tool.

    The BT Home Hub has a terrible security record.

    http://www.theregister.co.uk/2007/10...home_hub_vuln/
    http://www.theregister.co.uk/2008/01...oip_hijacking/

    And 64bit WEP encryption is worthless, that'd last less than a minute if anyone cared to try to break it.
