[英]PSRemotingTransportException in creating a Remote PowerShell Runspace in C#
我有以下代码可连接到远程计算机:
var credential = new PSCredential(username, securePassword);
var rri = new WSManConnectionInfo(new Uri(uri), schema, credential)
{
AuthenticationMechanism = AuthenticationMechanism.Kerberos,
ProxyAuthentication = AuthenticationMechanism.Negotiate
};
var remoteRunspace = RunspaceFactory.CreateRunspace(rri);
remoteRunspace.Open();
但这引发了以下异常:
System.Management.Automation.Remoting.PSRemotingTransportException was unhandled by user code
HResult=-2146233087
Message=Connecting to remote server sw-spdev02 failed with the following error message : WinRM cannot process the request. The following error with errorcode 0x80090311 occurred while using Kerberos authentication: There are currently no logon servers available to service the logon request.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
PowerShell ISE
的等效代码正常运行:
$cred = new-object -typename System.Management.Automation.PSCredential `-argumentlist 'domain\user', ('password' | ConvertTo-SecureString -AsPlainText -Force)
$session = New-PSSession http://servername -Credential $cred
作为提示,在运行此脚本之前,我也在ISE
也遇到了此异常:
Set-Item -Path WSMan:\localhost\Client\TrustedHosts -Value http://servername
另一点是,运行脚本的计算机和远程计算机位于不同的域中 。
为什么我在C#中而不在PowerShell ISE中收到此异常?
我不知道为什么! 但是我将代码更改为此并且它起作用了。 我刚刚将端口号设置为5985:
var rri = new WSManConnectionInfo(false, "sw-spdev02.mahanair.aero", 5985, "wsman",
"http://schemas.microsoft.com/powershell/Microsoft.PowerShell", credential)
{
ProxyAuthentication = AuthenticationMechanism.Negotiate,
AuthenticationMechanism = AuthenticationMechanism.Default,
};
我也使用了Username@Domain
样式,而不是@Donal在评论中说的Domain\\Username
。
我在尝试启动远程连接并执行命令时遇到这种错误,很可能是您使用了错误的凭据。 您可能要交叉检查您的凭据,使用您用于登录到计算机的凭据。
请注意,这里使用的是来自环境变量的相同凭据: 如果您使用Microsoft帐户登录到计算机,则有时使用环境变量可能会误导您。 请改用您的Microsoft凭据。
现在,如果您使用与Microsoft帐户相同的凭据,则可以使用。
