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
Default Server: d.center-dns.jsinfo.net
Address: 61.147.37.1
> server 192.168.0.20
Default Server: [192.168.0.20]
Address: 192.168.0.20
> www.yangdong.com
Server: [192.168.0.20]
Address: 192.168.0.20
Name: www.yangdong.com
Address: 192.168.1.11
