设置内部专用服务器以在我们的公司 LAN 上进行一些测试。我希望它对内部域和主机具有权威性,但能够解析互联网上的内容(谷歌、雅虎等)
我可以让内部部分正常工作,但是当我尝试解决公共问题时,它失败了。我的 /etc/named.conf 中可能缺少一个简单的标志(顺便说一句,RHEL 7.3 是我的操作系统)。
我可以粘贴我的配置内容,但我想从这里开始。
我一开始非常简单,只是为了让它发挥作用,然后计划随着我的进展添加更多。我只需要解决我当前遇到的外部解决问题。
谢谢!

编辑:神经病。我想我已经明白了。我必须在选项部分设置“转发器”并打开递归。现在,它正在按我想要的方式工作。

这是我在 Debian 上的内容/etc/bind
,其配置按照您所说的方式工作 - 对本地 LAN 上使用不可路由地址(在我的例子中为 10.99.99.0/24)的假域名/tld(称为 fake.tld)具有权威性使用 LAN 地址的反向 DNS 以及发送到全世界的“真实”DNS 的其他查找(在本例中,转发到 google 的 8.8.8.8)。此处唯一未显示的文件是/etc/bind/rndc.key
和/etc/bind/bind.keys
。文件名以粗体显示,文件结尾指示符以该文件的适当样式注释(即,在区域文件中)
命名的.conf:
// This is the primary configuration file for the BIND DNS server named.
