Linux下dns的简单配置

安装bind，执行/etc/rc.d/init.d/named start即可。
为了避免在执行nslookup时显示如下的警告信息
*** Can't find server name for address 10.0.0.1: Non-existent domain
*** Default servers are not available
Default Server:  UnKnown
Address:  10.0.0.1
可以在/etc/named.conf里头加入

zone "0.0.10.in-addr.arpa" IN {
        type master;
        file "named.10.0.0";
        allow-update { none; };
};

然后建立/var/named/named.10.0.0文件，内容如下

$TTL    86400
@       IN      SOA     localhost. root.localhost.  (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
              IN      NS      server.

1       IN      PTR     server.

重起named服务，再次执行nslookup时即会显示正确的信息
Default Server:  server
Address:  10.0.0.1
