我的linux ping任何地址出现Destination Host Unreachable
ping错误：
[root@ocp sbin]# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

--- 8.8.8.8 ping statistics ---

一直找不到什么原因，希望大神帮找下原因，我可以在下面贴上一些信息。
首先是ip
[root@ocp sbin]# ./ifconfig

防火墙：
[root@ocp sbin]# ./chkconfig --list iptables
iptables 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
路由：
[root@ocp sbin]# ./route -n

还有什么需要贴上
[解决办法]
把你的 /etc/sysconfig/network-scripts/ifcfg-eth0 改成下面这样
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
HWADDR=00:0C:29:7A:B0:F0
然后再运行
sudo ifdown eth0
sudo ifup eth0
试试
