无法使用SSH.NET库连接到AIX（Unix）框 – 错误：值不能为空

我正在尝试连接到AIX盒并使用SSH.NET库执行一些命令。 以下是代码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(); 

当我尝试在sshClient.Connect()行连接时收到以下exception消息

{“值不能为空。\ r \ nParameter name：data”}

堆栈跟踪是

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

我确信我传递的凭据是有效的，因为我能够使用具有相同凭据的PuTTY客户端登录 。 有任何想法吗？

Answer 1

经过一些研究，我找到了解决方案。 希望它能帮助别人。

应使用键盘交互式身份validation ，并使用以下函数覆盖AuthenticationPrompt事件

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

函数调用代码：

 KeyboardInteractiveAuthenticationMethod kauth = new KeyboardInteractiveAuthenticationMethod(username); PasswordAuthenticationMethod pauth = new PasswordAuthenticationMethod(username, password); kauth.AuthenticationPrompt += new EventHandler(HandleKeyEvent); ConnectionInfo connectionInfo = new ConnectionInfo(serverName, port, username, pauth, kauth); sshClient = new SshClient(connectionInfo); sshClient.Connect();

我把整个事情封装起来，以便更容易使用。 警告：还没有实现try / catch！ DLL可在此处获取： https： //sshnet.codeplex.com/releases/view/120504使用SLES（11.1 64），Debian（6），AIX（5.3,6.1,7）进行测试
