WSMan:
Short description
Provides access to Web Services for Management (WS-Management) configuration information.
Detailed description
The WSMan provider for PowerShell lets you add, change, clear, and delete WS-Management configuration data on local or remote computers.
The WSMan provider exposes a PowerShell drive with a directory structure that corresponds to a logical grouping of WS-Management configuration settings. These groupings are known as containers.
Beginning in Windows PowerShell 3.0, the WSMan provider has been
updated to support new properties for session configurations, such as
OutputBufferingMode. The session configurations appear as items in the
Plugin directory of the WSMan:
drive and the properties appear as items in
each session configuration.
The WSMan provider supports the following cmdlets, which are covered in this article.
Note
You can use commands in the WSMan:
drive to change the values of the new
properties. However, you cannot use the WSMan:
drive in PowerShell 2.0
to change properties that are introduced in Windows PowerShell 3.0.
Although no error is generated, the commands are not effective To change these
settings, use the WSMan drive in Windows PowerShell 3.0.
Organization of the WSMan: Drive
Client: You can configure various aspects of the WS-Management client. The configuration information is stored in the registry.
Service: You can configure various aspects of the WS-Management service. The configuration information is stored in the registry.
Note
Service configuration is sometimes referred to as Server configuration.
Shell: You can configure various aspects of the WS-Management shell, such as the setting to allow remote shell access (AllowRemoteShellAccess) and the maximum number of concurrent users allowed (MaxConcurrentUsers).
Listener: You can create and configure a listener. A listener is a management service that implements the WS-Management protocol to send and to receive messages.
Plugin: Plug-ins are loaded and used by the WS-Management service to provide various functions. By default, PowerShell provides three plug-ins:
- The Event Forwarding plug-in.
- The Microsoft.PowerShell plug-in.
- The Windows Management Instrumentation (WMI) Provider plug-in. These three plug-ins support event forwarding, configuration, and WMI access.
ClientCertificate: You can create and configure a client certificate. A client certificate is used when the WS-Management client is configured to use certificate authentication.
Directory Hierarchy of the WSMan Provider
The directory hierarchy of the WSMan provider for the local computer is as follows.
WSMan:\localhost
--- Client
--- Service
--- Shell
--- Listener
------ <Specific_Listener>
--- Plugin
------ Event Forwarding Plugin
--------- InitializationParameters
--------- Resources
------------ Security
------ Microsoft.Powershell
--------- InitializationParameters
--------- Resources
------------ Security
------ WMI Provider
--------- InitializationParameters
--------- Resources
------------ Security
--- ClientCertificate
The directory hierarchy of the WSMan provider for a remote computer is the same as a local computer. However, in order to access the configuration settings of a remote computer, you need to make a connection to the remote computer using Connect-WSMan. Once a connection is made to a remote computer, the name of the remote computer shows up in the provider.
WSMan:\<Remote_Computer_Name>
Navigating the WSMan: Drive
This command uses the Set-Location
cmdlet to change the current location to
the WSMan:
drive.
Set-Location WSMan:
To return to a file system drive, type the drive name. For example, type.
Set-Location C:
Navigating to a remote system store location
This command uses the Set-Location
command to change the current location
to the root location in the remote system store location. Use a backslash \
or forward slash /
to indicate a level of the WSMan:
drive.
Set-Location -Path WSMan:\SERVER01
Note
The above command assume that a connection to the remote system already exists.
Displaying the Contents of the WSMan: Drive
This command uses the Get-Childitem
cmdlet to display the WS-Management stores
in the Localhost store location.
Get-ChildItem -path WSMan:\Localhost
If you are in the WSMan:
drive, you can omit the drive name.
This command uses the Get-Childitem
cmdlet to display the WS-Management
stores in the remote computer "SERVER01" store location.
Get-ChildItem -path WSMan:\SERVER01
Note
The above command assume that a connection to the remote system already exists.
Setting the value of items in the WSMAN: drive
You can use the Set-Item
cmdlet to change configuration settings in the
WSMAN
drive. The following example sets the TrustedHosts value to
accept all hosts with the suffix "contoso.com".
# You do not need to specify the -Path parameter name when using Set-Item.
PS WSMAN:\localhost\Client> Set-Item .\TrustedHosts -Value "*.contoso.com"
The Set-Item
cmdlet supports an additional parameter -Concatenate
that
appends a value instead of changing it. The following example will append a
new value "*.domain2.com" to the old value stored in TrustedHost:
Set-Item WSMAN:\localhost\Client\TrustedHosts *.domain2.com -Concatenate
Creating items in the WSMAN: drive
Creating a new listener
The New-Item
cmdlet creates items within a provider drive. Each provider
has different item types that you can create. In the WSMAN:
drive, you can
create Listeners which you configure to receive and respond to remote
requests. The following command creates a new HTTP listener using the New-Item
cmdlet.
New-Item -Path WSMan:\localhost\Listener -Address * -Transport HTTP -force
Creating a new plug-in
This command creates (registers) a plug-in for the WS-Management service.
New-Item -Path WSMan:\localhost\Plugin `
-Plugin TestPlugin `
-FileName %systemroot%\system32\WsmWmiPl.dll `
-Resource http://schemas.dmtf.org/wbem/wscim/2/cim-schema `
-SDKVersion 1 `
-Capability "Get","Put","Invoke","Enumerate" `
-XMLRenderingType text
Creating a new resource entry
This command creates a resource entry in the Resources directory of a TestPlugin. This command assumes that a TestPlugin has been created using a separate command.
New-Item -Path WSMan:\localhost\Plugin\TestPlugin\Resources `
-ResourceUri http://schemas.dmtf.org/wbem/wscim/3/cim-schema `
-Capability "Enumerate"
Creating a new security entry for a resource
This command creates a security entry in the Security directory of Resource_5967683 (a specific resource). This command assumes that the resource entry has been created using a separate command.
$path = "WSMan:\localhost\Plugin\TestPlugin\Resources\Resource_5967683"
New-Item -Path $path\Security `
-Sddl "O:NSG:BAD:P(A;;GA;;;BA)S:P(AU;FA;GA;;;WD)(AU;SA;GWGX;;;WD)"
Creating a new Client Certificate
This command creates ClientCertificate entry that can be used by the WS-Management client. The new ClientCertificate will show up under the ClientCertificate directory as "ClientCertificate_1234567890". All of the parameters are mandatory. The Issuer needs to be thumbprint of the issuers certificate.
$cred = Get-Credential
New-Item -Path WSMan:\localhost\ClientCertificate `
-Issuer 1b3fd224d66c6413fe20d21e38b304226d192dfe `
-URI wmicimv2/* `
-Credential $cred;
Creating a new Initialization Parameter
This command creates an Initialization parameter named "testparametername" in the "InitializationParameters" directory. This command assumes that the "TestPlugin" has been created using a separate command.
New-Item -Path WSMan:\localhost\Plugin\TestPlugin\InitializationParameters `
-ParamName testparametername `
-ParamValue testparametervalue
Dynamic parameters
Dynamic parameters are cmdlet parameters that are added by a PowerShell provider and are available only when the cmdlet is being used in the provider-enabled drive.
Address <String>
Specifies the address for which this listener was created. The value can be one of the following:
- The literal string "*". (The wildcard character (
*
) makes the command bind all the IP addresses on all the network adapters.) - The literal string "IP:" followed by a valid IP address in either IPv4 dotted-decimal format or in IPv6 cloned-hexadecimal format.
- The literal string "MAC:" followed by the MAC address of an adapter. For example: MAC:32-a3-58-90-be-cc.
Note
The Address value is set when creating a Listener.
Cmdlets supported
Capability <Enumeration>
When working with Plug-ins this parameter specifies an operation that is supported on this Uniform Resource Identifier (URI). You have to create one entry for each type of operation that the URI supports. You can specify any valid attributes for a given operation, if the operation supports it.
These attributes include SupportsFiltering and SupportsFragment.
- Create: Create operations are supported on the URI.
- The SupportFragment attribute is used if the Create operation supports the concept.
- The SupportFiltering attribute is NOT valid for Create operations and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Delete: Delete operations are supported on the URI.
- The SupportFragment attribute is used if the Delete operation supports the concept.
- The SupportFiltering attribute is NOT valid for Delete operations and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Enumerate: Enumerate operations are supported on the URI.
- The SupportFragment attribute is NOT supported for Enumerate operations and should be set to False.
- The SupportFiltering attribute is valid, and if the plug-in supports filtering, this attribute should be set to "True".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Get: Get operations are supported on the URI.
- The SupportFragment attribute is used if the Get operation supports the concept.
- The SupportFiltering attribute is NOT valid for Get operations and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Invoke: Invoke operations are supported on the URI.
- The SupportFragment attribute is not supported for Invoke operations and should be set to False.
- The SupportFiltering attribute is not valid and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Put: Put operations are supported on the URI.
- The SupportFragment attribute is used if the Put operation supports the concept.
- The SupportFiltering attribute is not valid for Put operations and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Subscribe: Subscribe operations are supported on the URI.
- The SupportFragment attribute is not supported for Subscribe operations and should be set to False.
- The SupportFiltering attribute is not valid for Subscribe operations and should be set to "False".
Note
This operation is not valid for a URI if Shell operations are also supported.
- Shell: Shell operations are supported on the URI.
- The SupportFragment attribute is not supported for Shell operations and should be set to "False".
- The SupportFiltering attribute is not valid for Shell operations and should be set to "False".
Note
This operation is not valid for a URI if ANY other operation is also supported.
Note
If a Shell operation is configured for a URI, Get, Put, Create, Delete, Invoke, and Enumerate operations are processed internally within the WS-Management (WinRM) service to manage shells. As a result, the plug-in cannot handle the operations.
Cmdlets supported
CertificateThumbprint <String>
Specifies the thumbprint of the service certificate.
This value represents the string of two-digit hexadecimal values in the
Thumbprint field of the certificate. It specifies the digital public key
certificate (X509) of a user account that has permission to perform this
action. Certificates are used in client certificate-based authentication. They
can be mapped only to local user accounts, and they do not work with domain
accounts. To get a certificate thumbprint, use the Get-Item
or Get-ChildItem
cmdlets in the PowerShell Cert:
drive.
Cmdlets supported
Enabled <Boolean>
Specifies whether the listener is enabled or disabled. The default is True.
Cmdlets Supported
FileName (Plugin) <String>
Specifies the file name of the operations plug-in. Any environment variables that are put in this entry will be expanded in the users' context when a request is received. Because each user could have a different version of the same environment variable, each user could have a different plug-in. This entry cannot be blank and must point to a valid plug-in.
Cmdlets Supported
HostName <String>
Specifies the host name of the computer on which the WS-Management (WinRM) service is running.
The value must be a fully qualified domain name, an IPv4 or IPv6 literal string, or a wildcard character.
Cmdlets Supported
Issuer <String>
Specifies the name of the certification authority that issued the certificate.
Cmdlets Supported
Plugin <> WS-Management plug-ins are native dynamic link libraries (DLLs)
that plug in to and extend the functionality of WS-Management . The WSW-Management Plug-in API provides functionality that enables a user to write plug-ins by implementing certain APIs for supported resource URIs and operations. After the plug-ins are configured for either the WS-Management (WinRM) service or for Internet Information Services (IIS), the plug-ins are loaded in the WS-Management host or in the IIS host, respectively. Remote requests are routed to these plug-in entry points to perform operations.
Cmdlets Supported
Port <Unsigned Short Integer>
Specifies the TCP port for which this listener is created. You can specify any value from 1 through 65535.
Cmdlets Supported
Resource <String>
Specifies an endpoint that represents a distinct type of management operation
or value. A service exposes one or more resources, and some resources can have
more than one instance. A management resource is similar to a WMI class or to a
database table, and an instance is similar to an instance of the class or to a
row in the table. For example, the Win32_LogicalDisk class represents a
resource. Win32_LogicalDisk="C:\\"
is a specific instance of the resource.
A Uniform Resource Identifier (URI) contains a prefix and a path to a resource. For example:
http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_LogicalDisk
http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_NumericSensor
Cmdlets Supported
Resource <String>
Specifies the Uniform Resource Identifier (URI) that identifies a specific type of resource, such as a disk or a process, on a computer.
A URI consists of a prefix and a path to a resource. For example:
http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_LogicalDisk
http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_NumericSensor
Cmdlets Supported
SDKVersion <String>
Specifies the version of the WS-Management plug-in SDK. The only valid value is 1.
Cmdlets Supported
Subject <String>
Specifies the entity that is identified by the certificate.
Cmdlets Supported
Transport <String>
Specifies the transport to use to send and receive WS-Management protocol requests and responses. The value must be either HTTP or HTTPS.
Note: The Transport value is set when creating a Listener.
Cmdlets Supported
URI <String>
Identifies the URI for which access is authorized based on the value of the Sddl parameter.
Cmdlets Supported
URLPrefix <String>
A URL prefix on which to accept HTTP or HTTPS requests. This is a string
containing only the characters [a-z]
, [A-Z]
, [9-0]
,
underscore (_
) and backslash (/
). The string must not start with or end
with a backslash (/
). For example, if the computer name is "SampleComputer",
the WS-Management client would specify http://SampleMachine/URLPrefix
in the destination address.
Cmdlets Supported
Value <String>
Specifies the value of an initialization parameter, which is a plug-in-specific value that is used to specify configuration options.
Cmdlets Supported
XMLRenderingType <String>
Specifies the format in which XML is passed to plug-ins through the WSMAN_DATA object. The following are valid values:
- Text: Incoming XML data is contained in a WSMAN_DATA_TYPE_TEXT structure, which represents the XML as a PCWSTR memory buffer.
- XMLReader: Incoming XML data is contained in a WSMAN_DATA_TYPE_WS_XML_READER structure, which represents the XML as an XmlReader object, which is defined in the "WebServices.h" header file.
Cmdlets Supported
Using the pipeline
Provider cmdlets accept pipeline input. You can use the pipeline to simplify task by sending provider data from one cmdlet to another provider cmdlet. To read more about how to use the pipeline with provider cmdlets, see the cmdlet references provided throughout this article.
Getting help
Beginning in Windows PowerShell 3.0, you can get customized help topics for provider cmdlets that explain how those cmdlets behave in a file system drive.
To get the help topics that are customized for the file system drive, run a
Get-Help command in a file
system drive or use the -Path
parameter of
Get-Help to specify a file
system drive.
Get-Help Get-ChildItem
Get-Help Get-ChildItem -Path wsman:
