区域传输被拒绝

区域传输被拒绝

我花了很多时间来解决我的问题,但我没有完成我需要解决的问题。我认为可能是文件权限存在一些问题。我改变了我想使用以下命令从主服务器验证区域传输:

dig ns.insec -t axfr

这是来自主服务器的错误消息

Mar 16 03:49:30 ip-172-31-22-11 named[5395]: client        127.0.0.1#37251    
    (ns.insec): zone transfer 'ns.insec/AXFR/IN' denied

文件如下named.conf.options

acl "trusted" {
    localhost;
    172.31.0.0/20;
    localnets;
};

options {
    directory "/var/cache/bind";

    // If there is a firewall between you and nameservers you want
    // to talk to, you may need to fix the firewall to allow multiple
    // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

    // If your ISP provided one or more IP addresses for stable 
    // nameservers, you probably want to use them as forwarders.  
    // Uncomment the following block, and insert the addresses replacing 
    // the all-0's placeholder.

     forwarders {
        8.8.8.8;
     };

    //========================================================================
    // If BIND logs error messages about the root key being expired,
    // you will need to update your keys.  See https://www.isc.org/bind-keys
    //========================================================================
    dnssec-validation auto;

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { any; };
    forward only;
    allow-query-cache { trusted; };
    allow-query { trusted; };
    allow-recursion { trusted; };
    recursion yes;
    allow-transfer { 172.31.31.48; 127.0.0.1; };
    //also-notify { trusted; };
};

这是我的named.conf.local文件:

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

zone "ns.insec" {
    type master;
    file "/etc/bind/zones/db.ns.insec";
    allow-transfer { 172.31.31.48; };
    also-notify { 172.31.31.48; };
};

// 172.31.31.48 is the IP for slave 
// 172.31.22.11 is the IP for the master
zone "22.31.172.in-addr.arpa" {
    type master;
    file "/etc/bind/zones/db.172.31.22";
    allow-transfer { 172.31.31.48; };
    also-notify { 172.31.31.48; };

};

这是主服务器的文件权限快照,对于从属服务器也一样:

在此处输入图片描述

N:BI 可以dig ns.insec -t axfr从从服务器运行,但不能从主服务器运行

任何选项的全局声明(在 中)都可以被同一选项的局部声明(例如在 中)覆盖optionszoneview

您的情况也发生了同样的事情。

您有一个全局选项allow-transfer { 172.31.31.48; 127.0.0.1; };,该选项被区域定义中的声明覆盖。zone "ns.insec"因此allow-transfer { 172.31.31.48; };,您将无法将区域转移到本地主机。

zone "ns.insec"为了解决这个问题,请在以下位置进行声明

allow-transfer { 172.31.31.48; 127.0.0.1; };

或者,如果您想使用全局的(这并不总是一个好主意),请从定义中删除该allow-transfer指令。zone "ns.insec"
