One of the machines is not ours and we want to check it is not abuseing our internet link, so we want to know if there is any way to monitor bandwich usage from one of the other machines in the subnet with no need to modify the foreing machine config. Something like use tcpdump in promiscuos mode or something like that, we doesnt matter the content, we just need a bandwich conssumption meassure. Thanks for any ideas. Sdav
