Solaris 2 Primary Name Server DNS Primary Name

Solaris 2. 주 네임서버(Primary Name Server) • DNS 종류 – 주 네임서버 ( Primary Name Server ) – 이차 네임서버 ( Secondary Name Server ) – 캐시 전용 네임서버 ( Cache Only Name Server ) • DNS 구성 요소 – DNS 서버 데몬 ( in. named ) – DNS 설정 파일 ( /etc/named. conf ) – 존 데이터베이스 파일 ( /var/named/* )

Primary DNS 만들기 • /etc/named. conf 파일 편집 # vi /etc/named. conf options { directory "/var/named" ; }; zone ". " in { type hint; file "named. root" ; }; zone "corp 1. com" in { type master; file "corp 1. zone" ; allow-update { none ; }; };
