DNS

各位大虾,

请问RH7.1中的ndc在哪里??(每次修改了***.conf,没办法只能重新启动)

我用nslookup后出现一大串信息：
note:nslookup is a deprecated and maybe removed from feture released,consider using the 'dig' or 'host'..........
>
然后我输入www.bab.com.cn后出现
;; connection timed out; no servers could be reached 输入192.168.1.18后出现
;; connection timed out; no servers could be reached

出错在什么地方?是反向解析出错??

log中not at top of zone是什么意思?
