The interface is shown as up: # ifconfig -a em0: flags=8843 metric 0 mtu 1500 options=4019b ether 20:47:47:01:62:6e inet 10.70.14.139 netmask 0xffffff00 broadcast 10.70.14.255 nd6 options=29 media: Ethernet autoselect (1000baseT ) status: active and there's nothing obvious in dmesg or /var/log/messages, but the network is not working at all, e.g. can't ping /etc/resolv.conf hosts. Is anybody else seeing this? Thanks Anton
