/service network start 報錯：Bringing up interface eth0: Device does not seem to be present, delaying initialization. [FAILED]
解決辦法：ifconfig -a 查看eth0的HWaddr值
打開/etc/sysconfig/network-scripts/ifcfg-eth0 文件
修改為：
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
IPADDR=你的IP
NETMASK=255.255.255.192
HWADDR=00:16:3E:F2:A0:9C
重新啟動network服務，得以PING通
