Last time I checked, 'ifconfig' and similar output didn't show promisc when NIC was actually promisc, unless the user specified the promisc-ness. You can read /sys/class/net/dev/eth0/flags and see if flag 0x100 is set..if so, it's promisc. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
