I just got informed that in a week or two, my ISP, for no price increase, will speed things up a lot: 30Mbps down and 1Mbps up. BUT, they also introduce a quota, and I must not use more than 30GB of traffic per month.

BUT (yes another "but" ;-), when I open up the system monitor (System->Administration->System Monitor), I notice that there is always some traffic trickling downstream, for NO APPARENT reason ! I mean, I just start the machine, don't even start my e-mail client nor my web browser or anything ! :-O
> It's trickling at about 2 KB/s typically (but with random spikes of higher values !), which seemed harmless until I realised it adds up to nearly 200MB per day ! So that's a good chunk of the allowed 1 GB that's gone ! :-O

Hello

you should take a look at iptraf which is a great app for this purpose.
Also if you use firestarter for your iptable config, it has a status
view also.

I also noticed this kind of traffic here and it is mostly caused by some
 p2p actions somewhere on the net.
And there are constantly some pings ans other stuff out there. Although
this traffic isn´t for you it comes through your isp connection because
it is a shared medium at last.

bye Thilo
