無法連接到與SSH.NET圖書館AIX（UNIX）箱 - 錯誤：值不能爲空

Question

我試圖連接到一個AIX盒和使用SSH.NET庫執行某些命令。 以下是代碼snipplet

KeyboardInteractiveAuthenticationMethod kauth = new KeyboardInteractiveAuthenticationMethod(username); 
PasswordAuthenticationMethod pauth = new PasswordAuthenticationMethod(username, password); 

ConnectionInfo connectionInfo = new(ConnectionInfo(servername, 22, username, pauth,kauth); 
SshClient sshClient = new SshClient(connectionInfo); 
sshClient.Connect(); 
SshCommand sshCommand = sshClient.RunCommand("mpstat"); 
Console.WriteLine(sshCommand.Result); 
Console.ReadKey(); 

我得到以下異常消息當我嘗試在線路連接sshClient.Connect()

{「值不能爲空\ r \ n參數名：數據「}

堆棧跟蹤是

at Renci.SshNet.KeyboardInteractiveAuthenticationMethod.Authenticate(Session session) 
    at Renci.SshNet.ConnectionInfo.Authenticate(Session session) 
    at Renci.SshNet.Session.Connect() 
    at Renci.SshNet.BaseClient.Connect() 

我相信，我傳遞的憑據是有效的，因爲我能夠使用PuTTY客戶端使用相同的憑據登錄。有任何想法嗎？

Answer 1

經過一番研究，我找到了解決方案。希望它能幫助別人。

的鍵盤交互認證應使用AuthenticationPrompt事件應具有以下功能覆蓋

void HandleKeyEvent(Object sender, AuthenticationPromptEventArgs e) 
{ 
    foreach (AuthenticationPrompt prompt in e.Prompts) 
    { 
     if (prompt.Request.IndexOf("Password:", StringComparison.InvariantCultureIgnoreCase) != -1) 
     { 
      prompt.Response = password; 
     } 
    } 
} 

函數調用代碼：

KeyboardInteractiveAuthenticationMethod kauth = new KeyboardInteractiveAuthenticationMethod(username); 
PasswordAuthenticationMethod pauth = new PasswordAuthenticationMethod(username, password); 

kauth.AuthenticationPrompt += new EventHandler<AuthenticationPromptEventArgs>(HandleKeyEvent); 

ConnectionInfo connectionInfo = new ConnectionInfo(serverName, port, username, pauth, kauth); 

sshClient = new SshClient(connectionInfo); 
sshClient.Connect();

我封裝的全讓它更容易使用。警告：尚未實施try/catch！該DLL可在此處獲得：https://sshnet.codeplex.com/releases/view/120504 使用SLES（11.1 64），Debian（6），AIX（5.3，6.1，7）測試
