如何使用C＃远程登录到远程计算机？

Question

我正在尝试使用C＃编写一个小的命令行应用程序，该应用程序将提示输入用户名和密码，这些用户名和密码将用于登录到位于同一网络/域上的多台远程计算机并启动本地会话。

我尝试连接到远程计算机，并使用以下代码查询远程PC的操作系统信息：

ConnectionOptions options = new ConnectionOptions();

ManagementScope scope = new ManagementScope(@"\\REMOTE_COMPUTER_NAME");
scope.Connect();

ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

ManagementObjectCollection queryCollection = searcher.Get();

foreach (ManagementObject m in queryCollection)
{
    // Display the remote computer information
    Console.WriteLine("Computer Name : {0}", m["csname"]);
    Console.WriteLine("Windows Directory : {0}", m["WindowsDirectory"]);
    Console.WriteLine("Operating System: {0}", m["Caption"]);
    Console.WriteLine("Version: {0}", m["Version"]);
    Console.WriteLine("Manufacturer : {0}", m["Manufacturer"]);
}

但是，这只会返回我正在使用的本地PC上的信息，而不会返回远程PC上的信息。

我是否可以用此代码忽略某些内容？ 是否有合适的方法来完成我要完成的工作？

Answer 1

我现在没有远程计算机可以为您提供工作示例，但是您可以尝试一下。 advapi32.logonuser

例：

[DllImport("advapi32.dll")]
public static extern bool LogonUser(string name, string domain, string pass, 
int logType, int logpv, out IntPtr pht);

IntPtr ptr;
// LogonUser("username", "remotemachine", "password", 2, 0, out ptr);
LogonUser("username", "remotemachine", "password", 9, 0, out ptr);
WindowsIdentity windowsIdentity = new WindowsIdentity(ptr);
var impersonationContext = windowsIdentity.Impersonate();

// your code goes here...

impersonationContext.Undo();

此登录类型允许调用方克隆其当前令牌，并为出站连接指定新的凭据。 新的登录会话具有相同的本地标识符，但对其他网络连接使用不同的凭据。 注意：仅LOGON32_PROVIDER_WINNT50登录提供程序支持此登录类型。 注意：Windows NT：不支持此值。

尝试决明子

ITerminalServicesManager manager = new TerminalServicesManager();
using (ITerminalServer server = manager.GetRemoteServer("servername"))
{
    server.Open();
    foreach (ITerminalServicesSession session in server.GetSessions())
    { 
        Console.WriteLine("Hi there, " + session.UserAccount + " on session " + session.SessionId);
        Console.WriteLine("It looks like you logged on at " + session.LoginTime +
                            " and are now " + session.ConnectionState);
    }
}

您必须使用ConnectionOptions并将其传递给ManagementScope

    public void GetSystemInformation(string _yourDomain, string _hostName, string _userName, SecureString _password)
    {
        ManagementScope Scope = null;
        string computerName = _hostName;
        string userName = _userName;
        SecureString password = _password;
        ManagementObjectCollection collection = null;

        try
        {
            SelectQuery query = new SelectQuery("SELECT * FROM Win32_OperatingSystem");
            //string query = "SELECT * FROM Win32_NetworkAdapterConfiguration" + " WHERE IPEnabled = 'TRUE'";

            var options = new ConnectionOptions
            {
                  EnablePrivileges = false,
                  Impersonation = ImpersonationLevel.Impersonate,
                  Username = _userName,
                  SecurePassword = _password,
                  Authority = "ntlmdomain:" + _yourDomain
            };
            Scope.Options = options;
            Scope.Connect();

            ManagementObjectSearcher searcher = new ManagementObjectSearcher(Scope, query);
            collection = searcher.Get();

           //Do something with the collection
        }
        catch (ManagementException ex)
        {
            Console.WriteLine(ex.Message);
        }
        catch (UnauthorizedAccessException ex)
        {
            throw new ArgumentException(ex.Message);
        }
    }

    private static SecureString CreateSecuredString(string pw)
    {
        var secureString = new SecureString();

        foreach (var c in pw)
        {
            secureString.AppendChar(c);
        }

        return secureString;
    }

您可能需要使用变量EnablePrivileges和Impersonation尝试一些不同的统计信息
