辅助 DNS 不是最新的

我的 FreeBSD 服务器 ns0.dddddd.eu 上有一个主 DNS，Xname.org 上有一个辅助 DNS。

但是 Xname.org 上的辅助 DNS 不是最新的！命令“#dig @ns0.xname.org dddddd.eu mx”和“#dig @ns0.dddddd.eu dddddd.eu mx”返回不同的答案！NS 服务器看不到我的 MX 记录 mail2.dddddd.eu。为什么？请帮帮我！

#dig @ns0.xname.org dddddd.eu mx

答案1

您的区域序列号1看起来可疑。每次区域文件更改时，您都应该更新它，否则辅助服务器将不会更新。建议使用 2010082201 之类的序列号。

答案2

从历史上看，xname 与主服务器同步 DNS 数据的速度非常慢。

如果你正在寻找具有快速同步功能的产品，好友10 分钟内自动同步，或立即同步（如果您的主服务器支持 NOTIFY）。这是辅助 DNS 独有的，因此您需要主 DNS 才能使用它。
