DHCP ?

[pezz453]

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?

If it sent out DHCPDISCOVER and never gets a DHCPOFFER then either it timed out (stopped waiting for an OFFER) or the DHCP server is broken/not-working/not-serving. IF you want to know a bit more about how DHCP works, then http://www.softwaretipsandtricks.com/forum/showpost.php?s=7a47c8984b28d52e4c9202099d0cd123&p=53453&postcount=5 is a great link.

As for you situation, try stopping & restarting networking (does not require a reboot). As root user:
/etc/init.d/networking stop
then
/etc/init.d/networking start
