无法连接到AIX（UNIX）与SSH.NET库箱 - 错误：值不能为空(Unable to conn

我试图连接到一个AIX框，并使用执行某些命令SSH.NET库。 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();

我得到以下异常消息时，我尝试在线路连接sshClient.Connect()

{“值不能为空\ r \ n参数名：数据”}

堆栈跟踪为

   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，通过我的证书是有效的，因为我能够登录使用PuTTY客户端使用相同的凭据。 有任何想法吗？

Answer 1:

我发现了一些研究后的溶液。 希望它可以帮助别人。

键盘交互认证应使用AuthenticationPrompt事件应具有以下功能覆盖

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

函数调用的代码：

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();

我已经封装了整个事情，所以它更容易使用。 警告：没有的try / catch一直没有实现！ 该DLL可以在这里： https://sshnet.codeplex.com/releases/view/120504用SLES（11.1 64），Debian的（6），AIX测试（5.3，6.1，7）
