Description

The New-PSSessionOption cmdlet creates an object that contains advanced options for a PSSession. You can use the object as the value of the SessionOption parameter of cmdlets that create a PSSession, such as New-PSSession, Enter-PSSession, and Invoke-Command.

Without parameters, New-PSSessionOption generates an object that contains the default values for all of the options. Because all of the properties can be edited, you can use the resulting object as a template, and create standard option objects for your enterprise.

Parameters

-ApplicationArguments <PSPrimitiveDictionary>

Specifies a hash table that is sent directly to the session configuration without interpretation. This hash table is available to the session configuration as a property of the PSSenderInfo class.

Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-CancelTimeOut <int>

Determines how long Windows PowerShell waits for a cancel operation (CTRL + C) to complete before terminating it. Enter a value in milliseconds.

The default value is 60000 (one minute). A value of 0 (zero) means no timeout; the command continues indefinitely.

Required?	false
Position?	named
Default Value	60000
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-Culture <CultureInfo>

Specifies the culture to use for the PSSession. Enter a culture name in <languagecode2>-<country/regioncode2> format, such as "ja-jP", a variable that contains a CultureInfo object, or a command that gets a CultureInfo object, such as "Get-Culture".

The default value is $null, and the culture that is set in the operating system when the PSSession is created is used in the PSSession.

Required?	false
Position?	named
Default Value	Current culture
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-IdleTimeOut <int>

Determines how long the PSSession stays open if the remote computer does not receive any communication from the local computer, including the heartbeat signal. When the interval expires, the PSSession closes.

Enter a value in milliseconds. The default value is 240000 (4 minutes). The minimum value is 60000 (1 minute).

If both the local and remote computers specify an idle timeout value, the PSSession uses the shorter timeout value. The local computer can set an idle timeout value by using this parameter or by setting an idle timeout in the $PSSessionOption preference variable. The remote computer can specify an idle timeout value in the WS-Management configuration (WSMAN:\localhost\shell\idletimeout).

Required?	false
Position?	named
Default Value	240000
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-MaximumReceivedDataSizePerCommand <int>

Specifies the maximum number of bytes that the local computer can receive from the remote computer in a single command. Enter a value in bytes. By default, there is no data size limit.

This option is designed to protect the resources on the client computer.

Required?	false
Position?	named
Default Value	No limit
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-MaximumReceivedObjectSize <int>

Specifies the maximum size of an object that the local computer can receive from the remote computer. Enter a value in bytes. By default, there is no data size limit.

IdleTimeout                       : 00:04:00


Description
-----------
This command creates a session option object with all of the default values.

Example 2

C:\PS>$pso = new-pssessionoption -Culture "fr-fr" -MaximumReceivedObjectSize 10MB

C:\PS> new-pssession -computerName Server01 -SessionOption $pso


Description
-----------
This example shows how to use a session option object to configure a session.

The first command creates a new session option object and saves it in the value of the $pso variable.

The second command uses the New-PSSession cmdlet to create a PSSession on the Server01 remote computer. The command uses the session option object in the value of the $pso variable as the value of the SessionOption parameter of the command.

Example 3

C:\PS>enter-pssession -computername Server01 -sessionOption (new-pssessionoption -noEncryption -noCompression)

This command uses the Enter-PSSession cmdlet to start an interactive session with the Server01 computer. The value of the SessionOption parameter is a New-PSSessionOption command with the NoEncryption and NoCompression switch parameters.

The New-PSSessionOption command is enclosed in parentheses to make sure that it runs before the Enter-PSSession command.

Example 4

C:\PS>$a = new-pssessionoption

Description
-----------
This example demonstrates that you can edit the session option object. All properties have read/write values.

Use this method to create a standard session object for your enterprise, and then create customized versions of it for particular uses.

Example 5

C:\PS>$PSSessionOption = New-PSSessionOption -OpenTimeOut 120000

This command creates a $PSSessionOption preference variable. 

When the $PSSessionOption preference variable exists in the session, it establishes default values for options in the PSSessions that are created by using the New-PSSession, Enter-PSSession, and Invoke-Command cmdlets.

To make the $PSSessionOption variable available in all sessions, add it to your Windows PowerShell session and to your Windows PowerShell profile.

For more information about the $PSSessionOption variable, see about_Preference_Variables. For more information about profiles, see about_Profiles.

Example 6

C:\PS>$skipCN = new-pssessionoption -SkipCNCheck

C:\PS> new-pssession -computername 171.09.21.207 -UseSSL -credential domain01\user01 -sessionOption $skipCN


Description
-----------
This example shows how to use a SessionOption object to fulfill the requirements for a remote session configuration.

The first command uses the New-PSSessionOption cmdlet to create a session option object with the SkipCNCheck property. The command saves the resulting session object in the $skipCN variable.

The second command uses the New-PSSession cmdlet to create a new PSSession on a remote computer. The $skipCN check variable is used in the value of the SessionOption parameter. 

Because the computer is identified by its IP address, the value of the ComputerName parameter does not match any of the common names in the certificate used for Secure Sockets Layer (SSL). As a result, the SkipCNCheck option is required.
