一个新手的关于局域网dns的问题，急！！

djbking

我这个局域网里多数是windows的机器，要用redhat as 3.0作一个dns服务器，提供域名解析，老是不成功，不知什么原因
下面是我的配置文件named.conf
[root@xxzx etc]# more 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
//
controls {
        inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
        type hint;
        file "named.ca";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
};
zone "dxc.slof.com" {
       type master;
        file "named.dxc";
};
zone "123.67.10.in-addr.arpa" {
        type master;
        file "named.dxc.arpa";
};
include "/etc/rndc.key";
正解区域文件"named.dxc";的内容如下
[root@xxzx named]# more named.dxc
@       IN      SOA     xxzx.dxc.slof.com.      djbking210.126.com.
( 1999032401;
10800;
3600;
604800;
86400 );
@       IN      NS      xxzx.dxc.slof.com.
dong    IN      A       10.67.123.65

主机名xxzx，ip：10.67.123.13，linux操作系统，用来做dns服务器
主机名dong，ip：10.67.123.65，windows操作系统，用来做www服务器

我的目的就是在其他机器的地址浪里出入http://dong.dxc.slof.com,可以访问网页，而不必输入ip，可是不成功

不知道什么原因，是不时windows机器和linux机器还有设置域名，怎样设置，我第一次坐这个，不懂啊，
请有经验的大虾执教解惑！！

將 /var/log/messages 關於 named 部份的內容貼一貼?

mingjwan

默认情况下53端口是不对外开放的，你可以试试linux下配自己为dns，然后解析解析看时候成功。
iptables -t filter -I INPUT -p udp --dport 53 -j ACCEPT
service iptables save
然后重启机器，试试。

mingjwan

刚刚开始学习dns，对于下面一行是什么意思，我还有没有想通
@ IN NS xxzx.dxc.slof.com.

@ IN NS xxzx.dxc.slof.com

@是区域名称的简写，如果在正解区域文件里遇到@，则替换成在named.conf中声明的区域名称，如dxc.slof.com
IN 代表class字段，代表所制定的网络类型，通常固定为IN(internet)
xxzx.dxc.slof.com 声明域名服务器主机名称，就是此部dns的完整域名

mingjwan

那么xxzx.dxc.slof.com. 的ip地址又在什么地方给出的呢？
特别是里面配置了多个ns的时候。
