Ethernet设置为Bridged桥接方式，OpenSolaris的IP、网关、DNS都设置好了，但是不能上网。

1、在Win下
C:\Documents and Settings\Administrator>ping google.cn
Pinging google.cn [203.208.35.100] with 32 bytes of data:

2、修改/etc/hosts文件，加上   203.208.35.100       google.cn
发现浏览器在地址栏输入203.208.35.100能打开网站首页，但是用google.cn还是不行。

3、通过修改/etc/nsswitch.conf文件解决，能够输入域名打开网站，而且自带的IM工具MSN也能上。

修改/etc/nsswitch.conf，使客户机能够使用DNS服务，SUN客户机缺省使用files作为服务器名字的解析，为了使用DNS名称解析服务器，必须在/etc/nsswitch.conf指明使用DNS服务

vi命令比较重要，注:
/etc/hosts                     #IP地址 主机名
/etc/services                 #服务
/etc/resolv.conf              #nameserver DNS的IP
/etc/nsswitch.conf    #hosts:files dns
