BIND 区域传输的两个视图

BIND 区域传输的两个视图

我有一个简单的实验室/测试主/从配置(如下所示),我想将两个视图都传输给从属。

不幸的是,在区域传输之后,从属服务器的两个视图都有来自主服务器“外部”视图的记录。我在 serverfault 上阅读了几个有关类似问题的其他主题,但对我都不起作用。

主服务器(10.1.10.99):

acl "internals" {
    127.0.0.0/8;
    10.1.20.0/24;
};

acl "externals" {
    10.1.10.0/24;
};


key "external_key" {
algorithm hmac-md5;
secret "xxxxx";
};

view "internal"
{
also-notify {10.1.10.103; };

match-clients {key "!external_key"; "internals"; };

zone "example.com" {
    type master;
    file "/etc/bind/db.example.com";
};

[...]

view "external"
{

    match-clients {key "external_key";  "externals"; };
    server 10.1.10.103 { keys "external_key";};
    zone "example.com" {
        type master;
        file "/etc/bind/db.external.example.com";
    };
};

从属(10.1.10.103):

acl "internals" {
    127.0.0.0/8;
    10.1.20.0/24;
};

acl "externals" {
    10.1.10.0/24;
};


key external_key {
algorithm hmac-md5;
secret "xxxxx";
};

view "internal"
{

match-clients {key "!external_key" ;"internals"; };
zone "example.com" {
    type slave;
    masters {10.1.10.99;};
};

[...]

};

view "external"
{
    match-clients {key "external_key"; "externals"; };
    server 10.1.10.99 { keys "external_key";};
    zone "example.com" {
        type slave;
        masters { 10.1.10.99;};

    };
};


在我的奴隶上我得到:

Nov 24 23:36:24 ubuntu named[654]: zone example.com/IN/external: Transfer started.
Nov 24 23:36:24 ubuntu named[654]: zone example.com/IN/internal: Transfer started.

看起来两个视图都已正确传输,但在主视图上我得到:

Nov 24 23:36:23 ubuntu named[2240]: client @0x7f4a700d5cb0 10.1.10.103#58947/key external_key (example.com): view external: transfer of 'example.com/IN': AXFR started: TSIG external_key (serial 2006020201)
Nov 24 23:36:23 ubuntu named[2240]: client @0x7f4a700d5cb0 10.1.10.103#58947/key external_key (example.com): view external: transfer of 'example.com/IN': AXFR ended
Nov 24 23:36:23 ubuntu named[2240]: client @0x7f4a70057690 10.1.10.103#46287 (example.com): view external: transfer of 'example.com/IN': AXFR started (serial 2006020201)
Nov 24 23:36:23 ubuntu named[2240]: client @0x7f4a70057690 10.1.10.103#46287 (example.com): view external: transfer of 'example.com/IN': AXFR ended

看起来外部视图被转移了两次。

我也尝试遵循:https://kb.isc.org/docs/aa-00296但没有帮助。

任何建议/帮助都将不胜感激。

当前,当没有使用密钥时,从属设备会匹配“错误”的视图(根据您的 IP 匹配规则)。

最明显和最可靠的解决方案可能是为此目的为每个视图设置一个键,并根据每个视图中的所有键(正/负)进行匹配。
这样,您就可以消除当前哪个视图具有与其关联的键的因素,结合视图顺序,结合常规客户端的基于 IP 的匹配规则。使用您当前的方法,这种组合对于正确使用至关重要(问题源于这种组合不正确)。
