forward는 인식이 되는데 reverse가 인식이 안되요..

reverse의 zone파일내용을

$TTL 86400

으로 설정을 했고

/etc/named.conf의 내용은

include "/etc/rndc.key";

으로 설정을 하였는데..데몬을 살리면 /var/log/messages의 내용을 보면

Feb 11 14:28:04 localhost named[25301]: zone (IP거꾸로 3자리).in-addr.arpa/IN: loading master file (IP거꾸로 3자리).reverse: file not found

이런 메세지로 파일을 못찾는데 그 이유가 머죠~?
