编辑/etc/named.conf声明文件可否不写

thizlinux

1． 编辑/etc/named.conf
// generated by named-bootconf.pl

options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};

//
// a caching only nameserver config
//
我想问一关与上面的声明可不可以不写?它就是个声明应该没有啥作用对不对?

我認爲必須得寫
你可不可以DNS看成是一個大家的約定
你不按約定辦事，那你的事情能成功嘛
人家設計的時候能少一步當然少一步　
不能少的就是必要的啊

谢谢您的解释，在问一下上面的这个语句a caching only nameserver config是啥意思，谢谢！
