I can't figure this one out. There's a Belken USB->Ethernet adapter as eth2 on my server. After a reboot it doesn't communicate with anything ever though it's up: bounce the interface:
# ifconfig eth2 down # ifconfig eth2 up
now it works:
I don't know anything about how the USB->Ethernet dongle's setup (kernel modules etc.) but does it require something to be started that's not being run until after S10network in the init scripts?
Are there any errors in /var/log/messages or dmesg for ethernet or USB devices?
No errors that I can see. CentOS saw the device when I plugged it in, and after configuring it, it worked. It stops working after a reboot, but will come up and begin working once again after I bounce the interface.
