區域傳輸被拒絕

我花了很多時間來解決我的問題，但我沒有完成解決此問題所需的工作。

dig ns.insec -t axfr

這是來自主伺服器的錯誤訊息

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

這是named.conf.options文件：

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; };
};

這是我的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; };

};

這是主伺服器的檔案權限快照，從伺服器也相同：

在此輸入影像描述

N:BI 可以dig ns.insec -t axfr從伺服器上執行，但不能從主伺服器上執行

任何選項（在 中）的全域聲明都可以被同一選項的局部聲明（例如在,中）options覆蓋。zoneview

您的情況也發生了同樣的情況。

您有一個全域選項allow-transfer { 172.31.31.48; 127.0.0.1; };，該選項被區域定義中的聲明覆蓋zone "ns.insec"為allow-transfer { 172.31.31.48; };。因此您將無法將該區域轉移到本機。

zone "ns.insec"要解決這個問題，請在as中聲明

allow-transfer { 172.31.31.48; 127.0.0.1; };

或者，如果您想使用全域指令（這始終不是一個好主意），請從定義中刪除該allow-transfer指令。zone "ns.insec"
