如果只是本地网络的DNS, 可以不用做named.cache, 只要做本地ip和name的解析就可以了.

如果需要和internet连接, 可以在连接建立以后用 ' dig > named.cache ' 就可以了.

我做过一些,你说的方式可行,不过要在named.bbb中指向aaa.bbb.com子域.
具体方式是在named.bbb中加一条纪录:
aaa.bbb.com.    172800    IN    NS    DNS主机名
                (可不设)

可以配置DNS。是的,DNS HOWTO中的东西有点“过时”,新鲜的内容可以在
www.dns.net/dnsrd 里找到,成堆的好文章可以参考,另外,在www.unixworld.com里
也有几篇文章可以参考,我就是参考这两处的文章,并在姚飞大侠的帮助下搞定DNS
的。

我也感觉DNS-HOWTO讲的不清楚:-)

我看了一下你的几个配置文件,似乎有下面几个问题(我的理解也不一定准确,望各位
大侠批判!):

我认为你设定的域名是kaifenginfo.net.

1 我认为,SOA记录的格式是:
域名    IN     SOA    主机名    邮件地址(...)

容易搞错的地方是“主机名”。这里表示,DNS服务器位于那台机器上。

2 域名和主机名的界限不清晰。例如在kfinfo.net文件中:

ns              CNAME                 kaifenginfo.net.
ftp             CNAME                 kaifenginfo.net.
news            CNAME                 kaifenginfo.net.
mail            CNAME                 kaifenginfo.net.

我认为,kaifenginfo.net是域名,而这里应该写ns,ftp等服务器的名字,例如
ns.kaifenginfo.net,ftp.kaifenginfo.net等。
 

3 在各个文件中的NS记录似乎也有问题,也是主机名和域名混淆的问题。
                NS                    kaifenginfo.net.
                                         |
                                         ------这里填NS主机名
