    Our NAC box will OS fingerprint them when they connect, audit their machine with Nessus when they authenticate and then passively monitor them with snort. If they should incur it's wrath at any point during this process, they get arp poisoned and their mac address is blacklisted in the NAC database.
    That sounds tres cool... And being open source you can custom it to do all kinda cool stuff I bet like custom messages and upside down Internet tricks

    Personal laptops - a pain in the @55

    We have at least one teacher who refuses to use school laptops because they're "not very good", yet she is one of the people with regular problems. Unfortunately she's the head of English and gets pretty much what she wants.
    I've only been here three years, so there's till time to train them

    @Nick: I was considering the same sort of idea but in my local neighbourhood instead of in the school (it's a bit out in the sticks), and I came across this.

    Geoff, I keep on meaning to look at packetfence, how easy is it to install/maintain?

    Don't suppose you could spare some time to write a luser guide?

    It's easy if you start with the right distro (ie, the same one as the developers, Fedora). I did not. Thus it was entertainingly difficult to make go.

    I'll see what I can do about a guide. Although the documentation on the site is quite thorough.

    when we get asked if students/teachers can use their laptops in school, we reply "Yes sure, but we have to have administritive access over the machine so we can access the machine at any time, and you'll have to be a limited user"

    This normally gets a reply of "ah, ok...now worries...are there any spare laptops that I can use?"

    problem solved

    Thanks!

    Thanks for these everyone - I have enough ammo to stop this idiotic idea going any further. I will add some technomumbojumbo as well!!

    Geoff, do you know of any companies that install and maintain Packetfence or is it a DIY job?

    Packetfence was originally developed at Havard University. It's used at many other Universites in the USA and abroad.

    If you don't fancy DIYing it, use the VMWare version.

    This all sounds very cool.

    What is Nessus able to audit?

    Once blacklisted does the luser have to come grovelling or do you permanently ban that machine/user from accessing the network?

    Do you monitor for p2p usage?

    Our HM and Bursar are currently in a push to provide network/power points at ever desk in all refurbed classrooms. Personally i think it could work if we were providing the laptops but they are looking at it being personal ones. So currently looking at NAC and new switches around the entire college to give me more control over this.
