New-CimSession

Creates a CIM session.

Syntax

Parameter Set: CredentialParameterSet
New-CimSession [[-ComputerName] <String[]> ] [[-Credential] <PSCredential> ] [-Authentication <PasswordAuthenticationMechanism> ] [-Name <String> ] [-OperationTimeoutSec <UInt32> ] [-Port <UInt32> ] [-SessionOption <CimSessionOptions> ] [-SkipTestConnection] [ <CommonParameters>]

Parameter Set: CertificatePrameterSet
New-CimSession [[-ComputerName] <String[]> ] [-CertificateThumbprint <String> ] [-Name <String> ] [-OperationTimeoutSec <UInt32> ] [-Port <UInt32> ] [-SessionOption <CimSessionOptions> ] [-SkipTestConnection] [ <CommonParameters>]




Detailed Description

The New-CimSession cmdlet creates a CIM session. A CIM session is a client-side object representing a connection to a local computer or a remote computer. The CIM session contains information about the connection, such as ComputerName, the protocol used for the connection, session ID and instance ID.

This cmdlet returns a CIM session object that can be used by all other CIM cmdlets.

Parameters

-Authentication<PasswordAuthenticationMechanism>

Specifies the authentication type used for the user's credentials. The acceptable values for this parameter are: Default, Digest, Negotiate, Basic, Kerberos, NtlmDomain and CredSsp.

You cannot use the NtlmDomain authentication type for connection to the local computer. CredSSP authentication is available only in Windows Vista®, Windows Server® 2008, and later versions of Windows.

Caution: Credential Security Service Provider (CredSSP) authentication, in which the user’s credentials are passed to a remote computer to be authenticated, is designed for commands that require authentication on more than one resource, such as accessing a remote network share. This mechanism increases the security risk of the remote operation. If the remote computer is compromised, the credentials that are passed to it can be used to control the network session.

-CertificateThumbprint<String>

Specifies the digital public key certificate (X.509) of a user account that has permission to perform this action. Enter the certificate thumbprint of the certificate.

Certificates are used in client certificate-based authentication. They can be mapped only to local user accounts; they do not work with domain accounts.

To get a certificate thumbprint, use the Get-Item or Get-ChildItem cmdlets in the Windows PowerShell® Certificate provider. For more information about using the Windows PowerShell Certificate provider, type Get-Help Certificate, or see Certificate Provider on TechNet.

-ComputerName<String[]>

Specifies the name of the computer to which to create the CIM session. Specify either a single computer name, or multiple computer names separated by a comma.

If ComputerName is not specified, a CIM session to the local computer is created.

You can specify the value for computer name in one of the following formats:

One or more NetBIOS names
One or more IP addresses
One or more fully qualified domain names.

If the computer is in a different domain than the user, you must specify the fully qualified domain name.

You can also pass a computer name (in quotes) to New-CimSession by using the pipeline.

-Credential<PSCredential>

Specifies a user account that has permission to perform this action. If Credential is not specified, the current user account is used.

Specify the value for Credential by using one of the following formats:

A user name: "User01"
A domain name and a user name: "Domain01\User01"
A user principal name: "User@Domain.com"
A PSCredential object, such as one returned by the Get-Credential cmdlet.

When you type a user name, you are prompted for a password.

-Name<String>

Specifies a friendly name for the CIM session.

You can use the name to refer to the CIM session when using other cmdlets, such as the Get-CimSession cmdlet. The name is not required to be unique to the computer or the current session.

-OperationTimeoutSec<UInt32>

Duration for which the cmdlet waits for a response from the server.

By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for the server.

If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 minutes, network failures that last more than the value of the OperationTimeoutSec parameter are not recoverable, because the operation on the server times out before the client can reconnect.

-Port<UInt32>

Specifies the network port on the remote computer that is used for this connection. To connect to a remote computer, the remote computer must be listening on the port that the connection uses. The default ports are 5985 (the WinRM port for HTTP) and 5986 (the WinRM port for HTTPS).

Before using an alternate port, you must configure the WinRM listener on the remote computer to listen at that port. Use the following commands to configure the listener:

1. winrm delete winrm/config/listener?Address=*+Transport=HTTP
2. winrm create winrm/config/listener?Address=*+Transport=HTTP @{Port="<port-number>"}

Do not use the Port parameter unless you must. The port setting in the command applies to all computers or sessions on which the command runs. An alternate port setting might prevent the command from running on all computers.

-SkipTestConnection

By default, the New-CimSession cmdlet establishes a connection with a remote WS-Management endpoint for two reasons: to verify that the remote server is listening on the port number that is specified by using the Port parameter, and to verify the specified account credentials. The verification is accomplished by using a standard WS-Identity operation. You can add the SkipTestConnection switch parameter if the remote WS-Management endpoint cannot use WS-Identify, or if you want to reduce some data transmission time.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • None

    This cmdlet accepts no inputs.


Outputs

The output type is the type of the objects that the cmdlet emits.

Examples

Example 1: Create a CIM session with default options

This command creates a local CIM session with default options. If ComputerName is not specified, New-CimSession creates a DCOM session to the local computer.


PS C:\> New-CimSession

Example 2: Create a CIM session to a specific computer

This command creates a CIM session to the computer specified by ComputerName. By default, New-CimSession creates a WsMan session when ComputerName is specified.


PS C:\> New-CimSession -ComputerName Server01

Example 3: Create a CIM session to multiple computers

This command creates a CIM session to each of the computers specified by ComputerName, in the comma separated list.


PS C:\> New-CimSession -ComputerName Server01,Server02,Server03

Example 4: Create a CIM session with a friendly name

This command creates a remote CIM session on each of the computer specified by ComptuerName, in the comma separated list, and assigns a friendly name to the new sessions, by specifying Name.


 

Then you can use the friendly name of a CIM session to easily refer to the session in other CIM cmdlets, for example, Get-CimSession.


PS C:\> New-CimSession -ComputerName Server01,Server02 -Name FileServers

 

PS C:\> Get-CimSession -Name File*

Example 5: Create a CIM session to a computer using a PSCredential object

This command creates a CIM session to the computer specified by ComputerName, using the PSCredential object specified by Credential, and the authentication type specified by Authentication.

You can create a PSCredential object by using the Get-Credential cmdlet.


PS C:\> New-CimSession -ComputerName Server01 -Credential $cred -Authentication Negotiate

Example 6: Create a CIM session to a computer using a specific port

This command creates a CIM session to the computer specified by ComputerName using the TCP port specified by Port.


PS C:\> New-CimSession -ComputerName Server01 -Port 1234

Example 7: Create a CIM session using DCOM

This command creates a CIM session by using the Distributed COM (DCOM) protocol instead of WSMan.


 

PS C:\> $so = New-CimSessionOption -Protocol DCOM

 

PS C:\> New-CimSession -ComputerName Server1 -SessionOption $so
