Domain Name System (DNS)，中譯網域名稱系統 記得在竹高上計概時就已經有聽過這一名詞。摸到才知道自己沒學好，真的覺得多出來走走會學的比綁在學校 k 理論還來的多:P

Environment (環境)

jonny@ubuntu:~$ sudo apt-get install bind9

DNS Server Name：www.hjz.com.tw
IP Address：122.xxx.xxx.41

DNS Server Name：dns.hjz.com.tw
IP Address：122.xxx.xxx.41

jonny@ubuntu:~$ sudo vi /etc/bind/named.conf
...
//增加正解區域(Zone)
zone "hjz.com.tw" {
    type master;
    file "/etc/bind/db.hjz";
};

//增加反解區域(Zone)
zone "205.117.122.in-addr.arpa" {
    type master;
    file "/etc/bind/db.205.117.122";
};

include "/etc/bind/named.conf.local";

1. 備份原始參數
   

   jonny@ubuntu:/etc/bind$ sudo cp named.conf.options named.conf.options.bak



2. 更新參數
   

   jonny@ubuntu:/etc/bind$ sudo vi named,conf.options
   options {
       directory "/var/cache/bind";
       forwarders {
           168.95.1.1; 139.175.10.20; 203.133.1.6;
       };
       allow-query { any; };
       allow-transfer { none; };
   };

jonny@ubuntu:/etc/bind$ sudo vi db.hjz
