DNS实验报告
--杨冬
1.     实验的环境
 
服务器：Red Hat Enterprise Linux 5.3 （ip：192.168.0.20）
        Red Hat Enterprise Linux 5.3 （ip：192.168.0.30）
客户端：Windows XP （ip：192.168.0.1）
 
2.     实验前期准备
 
注：主、副都要安装以下软件包。
yum install –y bind caching-nameserver
或
rpm -ihv /media/Server/bind-9.3.4-10.P1.el5.i386.rpm
rpm -ihv /media/Server/caching-nameserver-9.3.4-10.P1.el5.i386.rpm
 
3. 实验目标一：实现简单的正、反DNS解析.
 
配置正向解析与反向解析.
①     vim /etc/named.caching-nameserver.conf
修改1：listen-on port 53 { 192.168.0.20; };//侦听端口的本机ip地址
修改2：//listen-on-v6 port 53 { ::1; };
修改3：//allow-query      { localhost; }; //永许哪些客户端访问DNS服务
修改4：//match-clients     { localhost; };
修改5：//match-destinations { localhost; };
 
②     vim /etc/named.rfc1912.zones
在结尾处添加：
 zone "yangdong.com" IN {
        type master;
        file "yangdong.zone";
//      allow-update { none; };
};
 
zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "yangdong.local";
//      allow-update { none; };
};
 
③      cd /var/named
cp -rf localhost.zone yangdong.zone
cp -rf named.local yangdong.local
chown named:named yangdong.local yangdong.zone
 
④      配置正向配置文件：
     vim yangdong.zone
     配置文件内容：
      $TTL    86400
@               IN SOA yangdong.com.       root (
                                        42              ; serial (d. adams)
                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
 
                IN NS           yangdong.com.
                IN A            192.168.0.20
www            IN A            192.168.0.21
wap             IN A            192.168.0.22
 
⑤     配置反向配置文件：
vim yangdong.local
配置文件内容：
$TTL    86400
@       IN      SOA     yangdong.com. root.yangdong.com. (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
        IN      NS      yangdong.com.
20      IN      PTR     yangdong.com.
21      IN      PTR     www.yangdong.com.
22      IN      PTR     wap.yangdong.com.
 
⑥     vim /etc/resolv.conf
nameserver 192.168.0.20
service network restart
 
⑦     service named restart
⑧     [root@hello named]# host www.yangdong.com
⑨     www.yangdong.com has address 192.168.0.21
⑩     [root@hello named]# host 192.168.0.22
22.0.168.192.in-addr.arpa domain name pointer wap.yangdong.com.
[root@hello named]# host wap.yangdong.com
wap.yangdong.com has address 192.168.0.22
[root@hello named]# host 192.168.0.20
20.0.168.192.in-addr.arpa domain name pointer yangdong.com.                                             
  
4.      实验目标二：配置主DNS和辅助DNS.
 主DNS：192.168.0.20
 副DNS：192.168.0.30
 
主DNS的配置：
①        vim /etc/named.rfc1912.zones
zone "yangdong.com" IN {
        type master;
        file "yangdong.zone";
//      allow-update { none; };
};
 
zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "yangdong.local";
//      allow-update { none; };
};
 
②        辅助DNS的配置.
vim /etc/named.caching-nameserver.conf
修改1：listen-on port 53 { 192.168.0.30; };//侦听端口的本机ip地址
修改2：//listen-on-v6 port 53 { ::1; };
修改3：//allow-query      { localhost; }; //永许哪些客户端访问DNS服务
修改4：//match-clients     { localhost; };
修改5：//match-destinations { localhost; };
 
③        vim /etc/named.rfc1912.zones
在结尾处添加：
zone "yangdong.com" IN {
        type slave;
        file "slaves/yangdong.zone";
//      allow-update { none; };
        masters { 192.168.0.20; };
};
 
zone "0.168.192.in-addr.arpa" IN {
        type slave;
        file "slaves/yangdong.local";
//      allow-update { none; };
        masters { 192.168.0.20; };
};
  
④          vim /etc/resolv.conf 
         nameserver 192.168.0.30
        service network restart
⑤          Service named restart
⑥       [root@dong ~]# ls /var/named/slaves/
yangdong.local yangdong.zone
⑦       [root@dong ~]# host www.yangdong.com
⑧       www.yangdong.com has address 192.168.0.21
⑨       [root@dong ~]# host 192.168.0.22
⑩       22.0.168.192.in-addr.arpa domain name pointer wap.yangdong.com.
[root@dong ~]# host wap.yangdong.com
wap.yangdong.com has address 192.168.0.22
 
5.      实验目标三：实现DNS智能双线服务
DNS server：192.168.0.20
① vim /etc/named.caching-nameserver.conf
配置文件最后修改内容：
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
        acl "dianxin" { 192.168.0.1/32; };
        acl "wangtong" {192.168.0.2/32; };
view dianxin {
        match-clients      { dianxin; };
//      match-destinations { localhost; };
        recursion yes;
//      include "/etc/named.rfc1912.zones";
        zone "yangdong.com" IN {
        type master;
        file "dianxin.zone";
};
};
view wangtong {
        match-clients      { wangtong; };
//      match-destinations { localhost; };
        recursion yes;
//      include "/etc/named.rfc1912.zones";
        zone "yangdong.com" IN {
        type master;
        file "wangtong.zone";
};
};
view localhost_resolver {
//      match-clients      { localhost; };
//      match-destinations { localhost; };
        recursion yes;
        include "/etc/named.rfc1912.zones";
};
 
② cd /var/named
cp –rf yangdong.zone dianxin.zone
cp –rf yangdong.zone wangtong.zone
chown named:named dianxin.zone wangtong.zone
 
③C:/Documents and Settings/Administrator>nslookup
