There are two options you could explore: * putting openwrt or another open-source firmware on those devices, if they support them. * Use a CentOS (since that's the list!) box with two NICs as a bridge and configure that for snooping. Or I guess option 3 would be to replace the routers with ones which do allow you use an open firmware. You could even do that temporarily just for the experiment. And finally, an option four: some router brands have their own proprietary bandwidth monitor tools. Asus, for example. (Note that you probably can't get full gigabit speeds with this enabled on an off-the-shelf consumer router, though.) -- Matthew Miller <mattdm at fedoraproject.org> Fedora Project Leader
