我正在创建一个用于从sftp服务器下载文件的窗​​口服务。为此我使用Renci.SshNet,Renci.SshNet.CommonRenci.SshNet.Sftp使用PPK密钥和密码进行多因素身份验证(非密码)

我有这样的代码:

String Host = "HostName"; 
int Port = 22; 
String RemoteFileDirectory = 
    Convert.ToString(ConfigurationManager.AppSettings["SourcePath"]); 
String Username = "UserName"; 
String Password = "*******"; 

var KeybasedMethod = new KeyboardInteractiveAuthenticationMethod(Username); 
KeybasedMethod.AuthenticationPrompt += 
    (sender, e) => { e.Prompts.First().Response = password; }; 

AuthenticationMethod[] methods = new AuthenticationMethod[] 
{ 
    new PrivateKeyAuthenticationMethod(Username, new PrivateKeyFile(@"Z:\SFTP SETUP\CJ22")), 
    KeybasedMethod 
}; 
ConnectionInfo connectionInfo = new ConnectionInfo(hostname, username, methods); 

using (var sftp = new SftpClient(connectionInfo)) 
{ 
    sftp.Connect(); 
    // ... 
} 

异常就说明是。

找不到合适的认证方法来完成认证。

据我所知这个错误是说我的凭证是错误的连接,但它不是这样的。

我尝试了以下解决方案,但都没有工作。

我无法弄清楚什么我缺少在我的代码。

下面是我在使用FileZilla从客户端计算机登录到服务器时获得的日志文件。

我试着从这里和其他来源多个解决方案一个接一个,但都没有工作。如果您有任何建议,那么这是非常值得欢迎的。

SSH.NET不支持.ppk密钥文件。您必须使用PuTTYgen将.ppk键转换为OpenSSH格式。

虽然你应该得到“无效的私钥文件。”例外,如果您尝试使用.ppk文件。


原来的答复,眼前的问题是编辑:

您正在使用FileZilla中多因素的私钥和键盘交互认证:

2017年4月3日16:25: 26 8120 3跟踪:从“Z:\ SFTP SETUP \ CJ22_PVT.ppk”提供公钥“
2017-04-03 16:25:26 8120 3跟踪:接受公钥的提供,尝试使用它进行身份验证。
2017-04-03 16:25:29 8120 3跟踪:需要进一步验证
2017-04-03 16:25:30 8120 3跟踪:使用键盘交互式验证。inst_len:0,num_prompts:1
2017-04-03 16:25:30 8120 3命令:密码:*********
2017-04-03 16:25:30 8120 3跟踪:访问授予

虽然,你正在使用简单的密码验证在你的代码:

using (var sftp = new SftpClient(Host, Port, Username, Password)) 

你怎么能指望即使这个工作?


要实施multicator身份验证,您必须使用ConnectionInfo

var keybInterMethod = new KeyboardInteractiveAuthenticationMethod(username); 
keybInterMethod.AuthenticationPrompt += 
    (sender, e) => { e.Prompts.First().Response = password; }; 

AuthenticationMethod[] methods = new AuthenticationMethod[] { 
    new PrivateKeyAuthenticationMethod(username, new PrivateKeyFile(privateKey)), 
    keybInterMethod 
}; 
ConnectionInfo connectionInfo = new ConnectionInfo(hostname, username, methods); 

using (var sftp = new SftpClient(connectionInfo)) 
{ 
    sftp.Connect(); 

    // ... 
}

我也尝试过这种方式......正如我在我的问题中所述。这是我尝试过的解决方案之一,但它不工作.....它给出了同样的错误。所以我在这里提出问题的同时来到我的主要版本。 – Chirag
