以下是具体情况：


[root@linux ~]# vi /etc/resolv.conf
search localdomain
nameserver 202.106.196.115
nameserver 202.106.0.20
~
[root@linux /]# rpm -qa |grep bind
bind-utils-9.3.3-7.el5
bind-libs-9.3.3-7.el5
bind-chroot-9.3.3-7.el5
bind-9.3.3-7.el5
ypbind-1.19-7.el5
[root@linux /]#

//ping 新浪网的域名不通啊

[root@linux /]# ping www.sina.com.cn
ping: unknown host www.sina.com.cn

[root@linux /]# nslookup www.sina.com.cn
;; connection timed out; no servers could be reached

//ping 新浪网的IP, 是通的

[root@linux /]# ping 202.108.33.32

说明不了什么问题呀，你如果想用自己的DNS服务的话，要看你的DNS服务是否配置正确。如果是用当地ISP的DNS服务器的话请把你的网关和DNS设置好就可以了
