정말 모르겠습니다
네임서버세팅을 마치고 nslookup을 처보니에라가 뜨네요
일단설정파일부터

*.zone파일과 *.rev 은 named-checkzone확인결과 0k가 떨어지는것로 아무 이상이 없는
것 같습니다

혹시couldn't open pid file '/var/run/named/named.pid': File exists에 에라가 있늑서 같아서
싸이트를 찾아 다니면서 /etc/group에 데몬에 내임드를 추가하고 run의 퍼미션을
바꾸고 도 해 보았지만 nslookup,host등다안되네요
웹은 인터닉에서 ns.도메인.com 과 ip를 넣으니깐 홈페이지는 뜨고요
www나도메인.com 같은 IN  A 설정부분은 아무것도 안됨니다
HOST에서 도메인을 너의면host xxxxxxxxxx.com
;; connection timed out; no servers could be reached
이런에러가 뜨고 nslookup 도 마찬가지 입니다.]
제발도 와주세요
전문가의 조언이 필요합니다.
