c# - 无法使用 SSH.NET 库连接到 AIX(Unix) 框 - 错误 : Value cannot be null

Question

我正在尝试连接到 AIX 机器并使用 SSH.NET 库执行一些命令。 以下是代码片段

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，我收到以下异常消息

{"Value cannot be null.\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，因为我可以使用具有相同凭据的 PuTTY 客户端登录 .有什么想法吗？

经过一番研究，我找到了解决方案。希望对其他人有帮助。

应该使用keyboard interactive authentication并且AuthenticationPrompt事件应该被下面的函数覆盖

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();
