一般这是由于里面的路由域名服务器没有配置好。

issta@ubuntu:~$ ping www.baidu.com
ping: unknown host www.baidu.com

先看一下地址解析器：

issta@ubuntu:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1

发现只是解析内网循环的。

所以添加google的域名服务器

issta@ubuntu:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1
nameserver 202.98.96.68
nameserver 61.139.2.69

 

加了这两个一般就可以了。后续雄起。。哈哈。

issta@ubuntu:~$ ping www.baidu.com

我使用的是桥接方式连的。两个都需要设置为桥接方式
