SocketException连接到SFTP服务器名称是有效的，但请求类型的数据发现 [英] SocketException connecting to SFTP server: name is valid, but no data of the requested type was found

问题描述

我想用SharpSsh库连接我的SFTP服务器，但我发现了以下错误：

I am trying to connect my sftp server using SharpSsh library, but I'm getting following error:

System.Net.Sockets.SocketException (0x80004005):
The requested name is valid, but no data of the requested type was found

我使用下面的code连接

I am using following code for connection

Tamir.SharpSsh.Sftp sftp = new Tamir.SharpSsh.Sftp("ftp.simptr.us", "username", "password");

为什么这个异常被抛出？

Why is this exception being thrown?

推荐答案

此错误消息的Winsock相关 WSANO_DATA 错误code。这意味着，有一些问题，你正在试图连接到该域名的DNS记录。

This error message is associated with Winsock WSANO_DATA error code. It means, there is some problem with DNS record of the domain name you are trying to connect to.

这是不可能的，这是关系到SharpSsh库。

It is unlikely this is related to SharpSsh library.

尝试远程登录验证，你应该得到同样的错误：

Try to telnet to verify, you should get the same error:

telnet ftp.simptr.us 22
