我在CentOS5.10上安装了一个转发DNS服务器,它正在解析地址,例如google.com。当我停止命名(服务名为stop)并尝试挖掘(google.com @localhost A)时,地址解析失败了。我检查并看到缓存守护进程nscd正在运行。
这是否意味着服务器根本没有缓存?我怎样才能让它缓存呢?

options
{
// Those options should be used carefully because they disable port
// randomization
// query-source port

我试图从我的MongoDB核心3.1应用程序连接到ASP.NET地图集:
var client = new MongoClient("mongodb+srv://<user>:<password>@<my_db_instance>/test?retryWrites=true&w=majority");

我得到了以下错误:
