[gentoo-user] eth0 cannot start up
hi, after a sudden power cut off, my gentoo system cannot connect to the network any more... the system can be started, but when starting dhcp, it reports Cannot assign requested address. if tried ifconfig eth0 up, it reports the same error. using dmesg|grep eth0 and dmesg|grep network, it shows the system has detected my network card. any idea what is the cause of the problem? -- Best Regards, Xi Shen (David) http://twitter.com/davidshen84/
Re: [gentoo-user] eth0 cannot start up
Run dhcpcd -k and check that dhcpcd does not leave any locks behind. Then run dhcpcd -d eth0 and see what's reported by it.

Re: [gentoo-user] eth0 cannot start up
i reboot the system, fresh start with livcd. all reports the same error. :( i noticed that the hardware address is 3a:3a:2d:6c:3a:3a, which is obviously an invalid one. i guess it is a hardware failure...

Hmm ... if ifconfig -a does not show your device then this merits further investigation. Does the LiveCD have the requisite driver for your eth0? In your normal OS the permanent udev rules could have messed up the order of your devices (assuming that you have more than one network interface) so that eth1 is now eth0. However, I am not sure that the LiveCD would show the same problem as it would run its own udev daemon. Either way, ifconfig -a should show all your interfaces and MAC numbers (as long as there is the appropriate driver in the kernel). If it is a hardware failure it may be worth trying to reseat the card if separate to the MoBo, or disable/enable in the BIOS to reset it. -- Regards, Mick

Hi, i had a similary problem, eth0 was away, but eth1 appeared insteadof.

That usually happens if you put in a new card, or MAC address changed somehow. Edit /etc/udev/rules.d/70-persistent-net.rules in that case to rename or remove the unwanted entries.

Re: [gentoo-user] eth0 cannot start up
normally, the latest livecd boot up the system, and everything works. if the livecd boot up and something is not working, i guess it must be a hardware issue. BTW, ifconfig -a does show my eth0 NIC, but ifconfig eth0 up cannot start my NIC.

try mii-tool if its compatible with the card sys-apps/net-tools-1.60_p20090728014017-r1 (/sbin/mii-tool) Add more -v to its command line and you get more info including a ROM readout.

Re: [gentoo-user] eth0 cannot start up
my NIC magically recovered :) i did nothing. i just wake up today, and turn my computer on, and it is as good as new.
