标准提问! 配置DNS后无法上网!

bing65

问题名称：配置DNS后(可能没成功),无法上网
问题提出者：bing65
问题简叙：不但上不了网,甚至网卡选择自动分配IP 时 都无法激活
问题目的：新手初学在LINUX下配置DNS,很想成功
联系信息：[email protected]
相关信息：
1、操作系统：
　　1).详细版本信息：RedHatLinux9.0
　　2).详细安装过程：光盘安装
　　3).详细配置过程：后附个相关配置文件
　　4).详细运行记录：哦,忘了在LINUX 下保存过来了
　　5).详细附加信息：我的电脑并不是作为宿舍的主机,但是,我想让自己的电脑又做自己的主机又做客户端,就是想学配置DNS嘛.理论上是可以的吧.

2、问题：
　　1).简短问题名称：不能上网啊,急
　　2).详细问题描述：之前也是配置一次DNS ,也是搞得上不了网,而且把配置文件搞得很乱,结果重装了系统,这次说什么也不靠重装了 .无论是否启动DNS都不能上网啊,郁闷并郁闷着
　　3).问题可能原因：连自动分配IP都不能激活网卡,实猜不到原因　(但是自己手动分配IP又可以激活网卡,可仍上不了网,更郁闷)
　　4).详细附加参考信息：这里填写对解决本问题有关的参考信息
下面是相关的一些配置文件,不知道够了没有:
host.conf
代码:
order hosts,bind

host.allow
代码:
#hosts.allow   This file describes the names of the hosts which are
#      allowed to use the local INET services, as decided
#      by the '/usr/sbin/tcpd' server.

host.deny
代码:
#hosts.deny   This file describes the names of the hosts which are
#      *not* allowed to use the local INET services, as decided
#      by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!

hosts
代码:
#Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1   localhost.localdomain   localhost

named.conf
代码:
key bing. {
       algorithm hmac-md5;
      secret "FuA/j4wFwm4l8jwZ7XaMrA==";
};

controls {
       inet 127.0.0.1 port 953
               allow { 127.0.0.1; } keys { bing.; };
};
acl our-inner-nets {127.0.0.1/32;192.168.1.1/8;};
//内部网络地址范围
options {
        directory "/var/named";
        allow-query {any;};
        allow-recursion{our-inner-nets;};
        notify yes;
        pid-file "named.pid";
};

        type hint;
        file "named.root";
};
zone "localhost" {
         type master;
         file "named.localhost";
};
zone "0.0.127.in-addr.arpa" {
        type master;
        file "named.127.0.0";
        
};

zone "7u7.net" {
        type master;
        file "named.7u7.net";
        notify no;
        };

zone "1.168.192.in-addr.arpa"{
         type master;
         file "named.192.168.1";
};

nsswitch.conf
代码:
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
#   nisplus or nis+      Use NIS+ (NIS version 3)
#   nis or yp      Use NIS (NIS version 2), also called YP
#   dns         Use DNS (Domain Name Service)
#   files         Use the local files
#   db         Use the local database (.db) files
#   compat         Use NIS on compat mode
#   hesiod         Use Hesiod for user lookups
#   [NOTFOUND=return]   Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

passwd:     files
shadow:     files
group:      files

#hosts:     db files nisplus nis dns
hosts:      files nisplus nis dns

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files      

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
services:   files

netgroup:   files

publickey:  nisplus

automount:  files
aliases:    files nisplus

我现在可以上网，但是只有输入IP才能打开网页，我也郁闷啦，我可能是没有配置好DNS，我也正在找办法，你可能先要把网卡的问题解决了才行，我也才搞这个不是很内行的，正学习着呢！
