My net was working just fine until I rebooted and got all this:

DHCPDISCOVER on etho0 to 255.255.255.255 port 67 interval 5
DHCPDISCOVER on etho0 to 255.255.255.255 port 67 interval 9
DHCPDISCOVER on etho0 to 255.255.255.255 port 67 interval 17
DHCPDISCOVER on etho0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on etho0 to 255.255.255.255 port 67 interval 2
NO DHCP OFFERS RECEIVED.

then, no net on startup.

any ideas?
