nel*_*aro 9 network-manager networking dns dhcp dnsmasq
当我尝试使用 Web 浏览器 ping 或浏览我们在本地网络上托管的某些域名时,它不起作用。然而,dig和nslookup 会正确返回它们的详细信息。我需要做什么来解决这个问题?
我们本地网络中的 DNS 服务器和 DHCP 服务器在 Windows 客户端上运行良好。

那个变化为我修复了它。mdns是 DNS 服务的一种特殊实现,它比 DNS 更快。它不能正确解析名称,并且从不使用 [NOTFOUND=return] 选项标准 DNS。这对于大多数互联网来说都很好,但由于某种原因,它不适用于我们的办公室解决方案。
通过更改解析以包含 DNS,我现在可以按预期 ping 域控制器。以及我们在本地办公室域上运行的其他服务。
