请教BIND的dlz方面ns跳转问题

njhc223

目前BIND+DLZ的NS记录可以dig，但是无法授权到子域中，请教下各位高手有没有遇到过。

参考了 http://www.cnblogs.com/tony-law/archive/2013/01/10/2855290.html ，在named.conf中的options里面增加了  allow-recursion   {any;}和  forwarders{}这两部分，前者是允许递归查询，后者是设置子域服务器，没有配置会找不到子域服务器；
options {
  directory "/usr/local/named/etc";
  pid-file "named.pid";
  allow-query { any; };
  listen-on {192.168.8.90;};
  listen-on {127.0.0.1;};
  allow-recursion   {any;};
  forwarders {

                192.168.8.110;

         };
但还是没查到。



linux-SuSE:/usr/local/named/etc # cat named.conf
key "rndc-key" {
        algorithm hmac-md5;
        secret "asdfasdfasdfasdf";
};

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

logging {
  channel query_log {
  file "/var/log/named.log" versions 3 size 20m;
    severity info;
    print-time yes;
    print-category yes;
    print-severity yes;
};
  category queries {
  query_log;
  };
};
options {
  directory "/usr/local/named/etc";
  pid-file "named.pid";
  allow-query { any; };
  listen-on {192.0.0.1;};
  listen-on {127.0.0.1;};
};
