    Hi Everyone,

    Here is my little issue. My fiance's Mum always has OS Students living
    with her and they love to nail her Optus bandwitch within the first few
    days of the month and cap the speed.

    All the laptops are running on wireless, is there a way to limit the
    amount of data all connected PC can use in a specific period?

    For example, all DHCP clients are alowed 2Gb traffic for 30 days.

    I don't want to limit their speed, just the amount of data they can
    download in a specific priod.

    Cheers, Chris.

  3. This is a "traffic quota". This is normally done at an ISP using
    monitoring software such as MRTG, RRDTOOL, PRTL, and various ISP
    billing programs. At some threshold, it simply pulls the plug on the
    account until the customer can cough up more cash to support their
    downloading habits.
    Such quota management is usually not implimented in the router. That's
    because users can change their IP addresses fairly easily and ruin the
    traffic accounting. Storing the logins and passwords in the router
    also becomes somewhat of a bloat problem. Normally, such quota
    management is done in a management workstation.

    Offhand, I don't know of a specific wireless device that will do what
    you're asking. However, it might exist and my sushi and saki fogged
    brain isn't sufficiently functional to recall the vendor.

    Until I recover, the best I can suggest is that you install a
    dedicated management workstation to collect traffic statistics by MAC
    address (by machine, not by IP address), and simply log the traffic.
    Logging can be done by sniffing or preferably by using SNMP. Then,
    split the bill according to usage. I've done this with MRTG a few
    times with fairly good results. Everyone overuses the system the
    first month. Then the bill arrives and they magically become more

    Search for "traffic accounting".

    This looks interesting:
    Total statistics for MRTG. The graphs shown are for the entire
    network traffic, but the data can be filtered or selectively polled by
    IP address or MAC address resulting in one page per MAC address (i.e.
    per machine).

    Another idea to consider would be to add another wifi router, one configured
    with wifi security (WPA) and setup solely for use by the guests. Then add
    the traffic monitoring, MRTG works well. It'd even be possible to track the
    live packet usage from the separate router and CUT IT OFF should the traffic
    exceed certain amounts.

    It'd end up being a bit of a configuration adventure, but you could do this
    with an old PC running linux and two ethernet cards. The PC would act as a
    'traffic cop'. Plug the student wifi router into one of it's ethernet
    ports, and plug the other into the ISP switch. Configure the student's wifi
    router as an access point, not as a gateway or a router. Then configure the
    PC as a router. Then just configure the scripts on it to cut off the
    ethernet port of the student wifi rig. You could get all sorts of fancy
    with configuring it. You could even set it up to re-direct ALL web traffic
    from the student port to a web page showing traffic stats if/when they run
    over the limits.

    So no, there's not one box that'll do it, at least not at a reasonable
    price. But a cheapie PC with linux and some configuring would do it quite
