  in-addr.arpa' (in '206.244.205.in-addr.arpa'?): 205.244.112.20#53

1. 修改 /etc/named.conf
[root@linux ~]# vi /etc/named.conf
// 加入底下这个参数：
logging {
        category lame-servers { null; };
};

2. 重新启动 bind
[root@linux ~]# /etc/init.d/named restart

command channel listening on 127.0.0.1#953

couldn't add command channel 127.0.0.1#953: not found

1. 先建立 rndc key 的相关数据吧！
[root@linux ~]# rndc-confgen
# Start of rndc.conf
key "rndc-key" {
        algorithm hmac-md5;
        secret "aoIyK4uoiR1hEqedk2D2lw==";
};

options {
        default-key "rndc-key";
        default-server 127.0.0.1;
        default-port 953;
};
# End of rndc.conf
# 上面的输出请将他贴到 rndc.conf 档案当中吧！
# Use with the following in named.conf, adjusting the allow list as needed:
# key "rndc-key" {
#       algorithm hmac-md5;
#       secret "aoIyK4uoiR1hEqedk2D2lw==";
# };
#
# controls {
#       inet 127.0.0.1 port 953
#               allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf
# 至于上面的 key 及 controls 的项目则贴到 named.conf 当中去！
# 请注意，这个 rndc-confgen 是利用随机数计算出加密的那把 key ，
# 所以每次执行的结果都不一样。所以上述的数据与你的屏幕会有点不同。

2. 建立 rndc.conf 档案
[root@linux ~]# vi /etc/rndc.conf
# 在这个档案当中将原本的数据全部删除，并将刚刚得到的结果给他贴上去
key "rndc-key" {
        algorithm hmac-md5;
        secret "aoIyK4uoiR1hEqedk2D2lw==";
};

options {
        default-key "rndc-key";
        default-server 127.0.0.1;
        default-port 953;
};
[root@linux ~]# chmod 640 /etc/rndc.conf  <==必需要设定好权限！
[root@linux ~]# chown root.named /etc/rndc.conf

3. 修改 named.conf
[root@linux ~]# vi /var/named/chroot/etc/named.conf
# 找到如下的这一行：
include "/etc/rndc.key";

# 将上述数据删除！因为该资料是旧的！然后加入这一段：
key "rndc-key" {
      algorithm hmac-md5;
      secret "aoIyK4uoiR1hEqedk2D2lw==";
};

controls {
      inet 127.0.0.1 port 953
              allow { 127.0.0.1; } keys { "rndc-key"; };
};

[root@linux ~]# /etc/init.d/named restart

[root@linux ~]# rndc
Usage: rndc [-c config] [-s server] [-p port]
        [-k key-file ] [-y key] [-V] command

command is one of the following:

  reload        Reload configuration file and zones.
  stats         Write server statistics to the statistics file.
  dumpdb        Dump cache(s) to the dump file (named_dump.db).
  flush         Flushes all of the server's caches.
  status        Display status of the server.
# 其他就给他省略啦！请自行输入这个指令来参考啰！

范例一：将目前 DNS 服务器的状态显示出来
[root@linux ~]# rndc status
number of zones: 6           <==这部 DNS 管理的 zone 数量
debug level: 0               <==是否具有 debug 及 debug 的等级
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF         <==是否将查询的数据记录下来？
server is up and running     <==主机目前正在运作当中

范例二：将目前系统的 DNS 统计数据记录下来
[root@linux ~]# rndc stats
# 此时，预设会在 /var/named/chroot/var/named/data 内产生新档案，你可以去查阅：
[root@linux ~]# cat /var/named/chroot/var/named/data/named_stats.txt
+++ Statistics Dump +++ (1161322745)
success 22
referral 0
nxrrset 0
nxdomain 3
recursion 6
failure 0
--- Statistics Dump --- (1161322745)

范例三：将目前高速缓存当中的数据记录下来
[root@linux ~]# rndc dumpdb
# 与 stats 类似，会将 cache 的数据放置成为一个档案，你可以去查阅：
# /var/named/chroot/var/named/data/cache_dump.db

rndc: connection to remote host closed
This may indicate that the remote server is using an older version of
the command protocol, this host is not authorized to connect,
or the key is invalid.
