    Checking which programs are choking my bandwidth?

    When using the system, suddenly the data light on the modem starts blinking fast and on checking the 'system monitor', I find that something is doing a lot of uploading and downloading, though I have no clue which program is doing that.

    How to check which programs are using the bandwidth and by how much?

    You could try nethogs.
    From man nethogs:
    NetHogs is a small ínet topí tool. Instead of breaking the traffic down per protocol or per subnet, like most such tools do, it groups bandwidth by process - and does not rely on a special kernel module to be loaded. So if thereís suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this, and if itís some kind of spinning process, kill it.
    Hope that helps.
