i seem to recall similar situation and the netplugd helped but in my case it was because the Cat5 cable was unplugged or the switch was powered off. i am not sure why it isn't on by default, maybe NetworkManager was supposed to take over the responsibilities of Netplugd, but clearly failed. ifconfig would say eth0 was UP even though it was not plugged-in. Since netplug daemon has been running, ifconfig hasn't lied again. IIRC, all i did to turn it on and enable it was, but you may have to yum it down first: chkconfig netplug on _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
