綁定 RPZ 與視圖沒有效果

綁定 RPZ 與視圖沒有效果

我有一台 DNS 伺服器,它有兩個視圖,一個用於內部用戶,一個用於外部(例如網際網路)。我想配置 RPZ,以便當內部用戶請求(外部遞歸查詢無論如何都會被拒絕)範例網站時,他們將被重定向到另一個網站(過濾器頁面),顯示不允許訪問該網站。但 RPZ 不起作用,查詢 bad.com 返回其真實地址。我找不到問題所在。

命名.conf.選項:

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;
 };


    response-policy {zone "filter" recursive-only no;};

    //========================================================================
    // 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; };
};

命名.conf.local:

//
// Do any local configuration here
//

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


acl internal {172.17.116/24; 192.168.20/24; 127/8;};

view "internal" {
    match-clients {internal;};
    recursion yes;
    zone "wsi.org" {
        type master;
        file "/etc/bind/internal.zone";
    };

    zone "filter" {
        type master;
        file "/etc/bind/filter.zone";
    };



    include "/etc/bind/named.conf.default-zones";
};

view "external" {
    match-clients {any;};
    recursion no;
    zone "wsi.org" {
        type master;
        file "/etc/bind/external.zone";
    };

    zone "filter" {
        type master;
        file "/etc/bind/filter2.zone";
    };


    include "/etc/bind/named.conf.default-zones";
};

過濾區:

TTL 604800
@   IN  SOA wsi.org. root.wsi.org. (
                  3     ; Serial
             604800     ; Refresh
              86400     ; Retry
            2419200     ; Expire
             604800 )   ; Negative Cache TTL

bad.com A   filter.wsi.org
bad.net A   filter.wsi.org

過濾器2區域:

TTL 604800
@   IN  SOA wsi.org. root.wsi.org. (
                  3     ; Serial
             604800     ; Refresh
              86400     ; Retry
            2419200     ; Expire
             604800 )   ; Negative Cache TTL

bad.com A   filter.wsi.org
bad.net CNAME   rpz-passthru

nslookup始終顯示 bad.net 和 bad.com 的真實地址。

我正在嘗試,這就是為什麼有兩個區域。

答案1

第一個正確的 A 記錄來自:

bad.com A   filter.wsi.org 

到:

bad.com A   192.168.1.1

或像下面這樣改:

bad.com CNAME   filter.wsi.org

並使用以下測試配置:

response-policy {zone "filter";};

答案2

我發現另一個問題,你沒有在 rpz 區域檔案中定義 ns 記錄。

@   NS    127.0.0.1.

並使用綁定工具對您的配置進行故障排除。用於檢查配置語法:

named-checkconf

並檢查區域檔案語法:

named-checkzone filter /etc/bind/filter.zone

並檢查綁定是否正在運行而沒有錯誤:

netstat -lntup | grep 53
