使用 Webmin方式來設定DNS Server

設定 Bind 8 可以接受外部連線及轉送查詢的伺服器。
「伺服器」->「BIND 8 DNS 伺服器」->「Edit Config File」->/etc/bind/named.conf.options
在此檔中加入
 
listen-on port 53 { any; };
forwarders {
        163.168.168.59;   //base DNS IP
        8.8.8.8;  //google DNS IP

        };
    allow-query {
        any;
        };

設定區域預設值

「伺服器」->「BIND 8 DNS 伺服器」->「區域預設值」
「預設的區域設定」->「允許從 ... 的查詢」點擊「監聽」及輸入 [any]
 






建立一個新的主控區域-正向
輸入管理網域名稱 test.local

 

建立 Address 紀錄(位址)

 增加 Address 紀錄
 

step 4.

使用nslookup指令查詢

nslookup
server "DNS Server IP"
set type=srv
_sip._udp.test.local
