CentOS5： Device eth0 has different MAC address than expected

Posted on by

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。

[root@banyue.net ~]# dmesg | grep eth0
divert: allocating divert_blk for eth0
eth0: RTL-8139C+ at 0xd0842000, 40:61:86:ED:25:E7, IRQ 11

[root@banyue.net ~]# 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

CentOS setup命令

最小化安装CentOS后,没有setup命令,后用yum install setuptool安装了setup,可是运行时只有Authentication configuration和Firewall configuration两项,没有时区、系统服务等其他几项，有时候新手会很痛苦，其实用以下命令你就可以找到你想要的项目啦。

yum install setuptool
yum install ntsysv
