如何使用C＃远程登录到远程计算机？

Question

I'm trying to write a small command line application with C# that will prompt for a username and a password that will be used to login to several remote computers that are sitting on the same network/domain and start a local session.

I've tried connecting to a remote computer and to query the remote PC's operating system info with the following code:

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"]);
}

However, this only returns information on the local PC that I'm working on and not on the remote PC.

Am I overlooking something with this code? And is there an appropriate approach to accomplish what I am trying to do?

Answer 1

I don't have remote machine right now to give you the working example, but you can try this. advapi32.logonuser

Example:

[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();

This logon type allows the caller to clone its current token and specify new credentials for outbound connections. The new logon session has the same local identifier but uses different credentials for other network connections. NOTE: This logon type is supported only by the LOGON32_PROVIDER_WINNT50 logon provider. NOTE: Windows NT: This value is not supported.

Edit

Give it a try cassia

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);
    }
}

You have to use ConnectionOptions and pass it to the 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;
    }

You might have to try some different stats with the variables EnablePrivileges and Impersonation

edit:

If you want to get your information from your pc (local) than you dont have to pass the options to the scope.
