请教linux DNS服务器配置的一个问题

有这样一台主机abc. (可以被外网访问)以及它的ip[假设为：111.222.10.2]，abc.的dns就是的dns，我现在想把abc.设置为一个dns服务器，用来解析me.abc.[111.222.10.3]，就是能够让外网通过abc.来解析到me.abc.。
请问在abc.上需要怎样配置呢？所有abc.为linux
我试着在abc上配置，在named.conf中加入以下内容：
zone "abc. in {
        type master;
        file "abc.
};

zone "10.222.111.in-addr.arpa" in {
        type master;
        file "111.222.10.zone";
};
在 "111.222.10.zone" 加入：
$TTL 1D
@               IN SOA          abc.   root.abc. (
                                42              ; serial (d. adams)
                                2D              ; refresh
                                4H              ; retry
                                6W              ; expiry
                                1W )            ; minimum

                IN NS           abc.
3             IN PTR          me.abc.

在”abc.“加入：
X
$TTL 1D
@               IN SOA  @  abc. root.abc. (
                                42              ; serial (d. adams)
                                2D              ; refresh
                                4H              ; retry
                                6W              ; expiry
                                1W )            ; minimum

                IN NS           abc.
me          IN A            111.222.10.3


请问哪里有问题呢？谢谢
