CentOS5： Device eth0 has different MAC address than expected

http://sys.firnow.com/linux/x8002010n08m/27s90182462.html

Centos/linux重启出现错误信息：

Device eth0 has different MAC address than expected

应该是dmesg 和 eth0 配置文件之间的冲突。

[[email protected] ~]# dmesg | grep eth0

divert: allocating divert_blk for eth0

eth0: RTL-8139C+ at 0xd0842000, 40:61:86:ED:25:E7, IRQ 11

[ro[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=static

HWADDR=40:61:86:ED:35:17

ONBOOT=yes

TYPE=Ethernet

IPADDR=192.168.122.101

NETMASK=255.255.255.0

GATEWAY=192.168.122.1

DNS1=192.168.122.1

改正很简单，HWADDR=40:61:86:ED:35:17 改成正确的40:61:86:ED:25:E7 就OK了

HWADDR=40:61:86:ED:25:E7

如果你用dmesg | grep eth0这个命令看不到MAC地址的话，可以用ifconfig eth0这个命令来看。看到就记录下来，在ifcfg-eth0中改就可以了。
