Ubuntu
PowerDNS 和 Bind9 之間的區域傳輸
嘗試將完整區域從 PowerDNS 伺服器傳輸到 Bind9 伺服器時遇到問題。奇怪的是，PowerDNS 伺服器上有幾個區域用作隱藏的主伺服器（帶有 MySQL 後端），但只有一個區域無法傳輸到 Bind9 伺服器。
兩台伺服器都執行 Ubuntu 16.04 LTS。和：
- Bind9 版本 = 9.10.3.dfsg.P4-8ubuntu1
- PowerDNS 版本 = 4.0.0~alpha2-3build1
Bind9 從區配置如下：
zone "example.net" { type slave; file "/var/lib/bind/slaves/db.example.net"; masters { 10.0.0.1; }; };PowerDNS 的 DNS 區域是：
% sudo pdnsutil show-zone example.net This is a Master zone Last SOA serial number we notified: 2016050801 == 2016050801 (serial in the database) Zone is not actively secured Metadata items: None No keys for zone 'example.net.'. % sudo pdnsutil list-zone example.net example.net. 10800 IN MX 10 mx1.example.org. example.net. 10800 IN MX 50 mx2.example.org. example.net. 10800 IN NS ns1.example.org. example.net. 10800 IN NS ns2.example.org. example.net. 86400 IN SOA ns1.example.org. hostmaster.example.org. 2016050801 28800 7200 604800 86400 ...請注意此輸出中**.net和.org**之間的區別。這是在嘗試將區域提供給 Bind 時日誌中的 PowerDNS 輸出。

% dig @10.0.0.1 example.net. SOA ; <<>> DiG 9.10.3-P4-Ubuntu <<>> @10.0.0.1 example.net.

謝謝你的幫助。

應我的要求，發帖人進入了我們的#powerdns IRC 頻道，我們很快發現主伺服器和從伺服器的域名之間實際上存在拼寫錯誤 - 在這裡提出問題時所做的混淆隱藏。
我猜在這裡，因為你基本上隱藏了所有有用的東西。你是否故意讓幫助你變得困難？
看起來
example.net您的表格中有一個條目domains，但在表格中domain_id的條目下records，您放置了example.org記錄。pdnsutil check-all-zones（或者pdnssec如果您使用的是 3.x）可能會注意到這一點。
