Without carrier, system hangs. With cable plugged in, vr0 doesn't work properly. Dhclient fails. Even manually ifconfig vr0 to a IP, machine cannot ping the gateway. Plugged in a fxp0 NIC and dhclient works on fxp0. So, I wonder if this vr driver issue or is it a bad NIC? (vr0 is on board NIC). -- ------------ Jin Guojun ----------- v --- jin@george.lbl.gov --- Distributed Systems Department http://www.dsd.lbl.gov/~jin Lawrence Berkeley National Laboratory, Berkeley, CA 94720
