無法使用綁定載入反向區域
我創建了一個簡單的綁定 dns 伺服器來在測試實驗室中託管 3 個區域。
- 浴.local (192.168.100.0/24)
- 慕尼黑本地 (192.168.101.0/24)
- dhcp.local (192.168.99.0/24)
我想要正向和反向解析,但我無法驗證反向配置。
我是否在這裡遺漏了一些關鍵概念,或者這只是一個錯字?
提前謝謝了!
我使用以下作為我的
/etc/named.conf
// // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { listen-on port 53 { 127.0.0.1; 192.168.99.2; 192.168.100.2; 192.168.101.2; }; ### Master DNS IP ### listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; allow-query { localhost; 192.168.99.0/24; 192.168.100.0/24; 192.168.101.0/24; }; ### IP Range ### recursion yes; dnssec-enable no; dnssec-validation no; // dnssec-lookaside auto; /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key"; managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; zone "." IN { type hint; file "named.ca"; }; zone "dhcp.local" IN { type master; file "forward.dhcp.local"; allow-update { none; }; }; zone "bath.local" IN { type master; file "forward.bath.local"; allow-update { none; }; }; zone "munich.local" IN { type master; file "forward.munich.local"; allow-update { none; }; }; zone"99.168.192.in-addr.arpa" IN { type master; file "reverse.dhcp.local"; allow-update { none; }; }; zone"100.168.192.in-addr.arpa" IN { type master; file "reverse.bath.local"; allow-update { none; }; }; zone"101.168.192.in-addr.arpa" IN { type master; file "reverse.munich.local"; allow-update { none; }; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key";
這依賴於 3 個正向和 3 個反向文件
/var/named/[forward.*|reverse.*]
/var/named ├── data ├── dynamic ├── forward.bath.local ├── forward.dhcp.local ├── forward.munich.local ├── named.ca ├── named.empty ├── named.localhost ├── named.loopback ├── reverse.bath.local ├── reverse.dhcp.local ├── reverse.munich.local └── slaves
只選擇一個(bath.local),前向配置是
[root@dhcp named]# cat forward.bath.local $TTL 86400 @ IN SOA dns.bath.local root.bath.local. ( 2011071001 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) @ IN NS dns.bath.local. @ IN A 192.168.100.2 dns IN A 192.168.100.2 router IN A 192.168.100.1
反向配置是
$$ root@dhcp named $$# cat reverse.bath.local
$TTL 86400 @ IN SOA dns.bath.local. root.bath.local. ( 2011071001 ;Serial 3600 ;Refresh 1800 ;Retry 604800 ;Expire 86400 ;Minimum TTL ) 100.168.192.in-addr.arpa. IN NS dns.bath.local. 2 IN PTR dns.bath.local.
當我驗證正向配置時一切正常
[root@dhcp named]# named-checkzone tsvtest /var/named/forward.bath.local zone tsvtest/IN: loaded serial 2011071001 OK
但反向失敗
[root@dhcp named]# named-checkzone tsvtest /var/named/reverse.bath.local /var/named/reverse.bath.local:9: ignoring out-of-zone data (100.168.192.in-addr.arpa) zone tsvtest/IN: has no NS records zone tsvtest/IN: not loaded due to errors.
有任何想法嗎 ?
(Common) Fwd zone,第 2 行 dns.bath.local 需要在 dns.bath.local 後面加一個句點。
刪除第 9 行
====== 反向區域 1) BIND 希望將該反向文件命名為 100.168.192.in-addr.arpa BINDD 反向文件中指定的域是 IP 子網的名稱而不是正向域的名稱。你的revese文件與bath.local有關,與192.168.100.x有關
第 9 行 - 從行首刪除 100.168.192.in-addr.arpa。
請發布您的 /etc/named.conf 以便我們檢查其中的內容。
