안녕하세요.
dns를 사용하려고 하는데 외부로 nslookup이 안먹습니다.
어디가 문제인지요?

버전 bind 9.2.2

1. 데몬은 잘돌고 있습니다.
# ps -ef | grep named
   named   420     1  0 20:30:34 ?        0:00 ./in.named -u named
   root   592   567  0 12:32:39 pts/3    0:00 grep named

2. 로칼호스트에서는
 nslookup이 잘먹습니다.
# nslookup localhost
Server:  www.iww9.com
Address:  203.237.216.145

Name:    localhost
Address:  127.0.0.1


3. 203.237.216.145에 www.iww9.com이라는
 도메인을 받았는데
여기서도 잘됩니다.

# nslookup www.iww9.com
Server:  www.iww9.com
Address:  203.237.216.145

Name:    www.iww9.com
Address:  203.237.216.145

4. ip로 nslookup 하면 역시 로칼에서만 됩니다.

# nslookup 203.237.216.145
Server:  www.iww9.com
Address:  203.237.216.145

Name:    www.iww9.com
Address:  203.237.216.145

------------------

# nslookup 203.237.216.2
Server:  www.iww9.com
Address:  203.237.216.145

*** www.iww9.com can't find 203.237.216.2: Non-existent host/domain
# 


5.ping을 www.iww9.com로 날리면 살아있습니다.

6. 로칼호스트가 아닌 다른 컴퓨터에 질의를 날리면
먹통입니다.
# nslookup www.joins.com
Server:  www.iww9.com
Address:  203.237.216.145
