Slave DNS 구성하기
Slave DNS는 Master DNS의 zone파일을 백업하는 역할을 하는 서버이다.

Master DNS의 IP주소: 218.38.35.252
Slave DNS의 IP주소 : 218.38.35.253

Master DNS /etc/named.conf

options {
//
//name server boot file
//
//type domain source file or host
directory "/var/name";
allow-transfer { 218.38.35.253; };
};

zone "." in {
type hint;
file "named.ca";
};

zone "backrush.com" in {
type master;
file "backrushcom.zone";
};

zone "35.38.218.in-addr.arpa" in {
type master;
file "backrushcom.rev";
};

zone "0.0.127.in-addr.arpa" in {
type master;
file "backrushcom.loop";
};


Slave DNS서버에 /var/name디렉토리 생성후 named.ca카피
아래와같이 named.conf파일을 설정후 named데몬을
재구동하면 Master dns 서버에서 zone과 reverse파일을
자동으로 카피해온다.
