Principle
Using the "Local Group Policy Editor", it is possible to add the execution of a Powershell script at Windows shutdown. As this operation is performed with the "system" account, some operations have to be performed if the chosen mode is "rsh" or "ssh".
There is no specific operation to perform if "expect" mode is selected.
rsh mode preparation
A proxy has to be defined at OpenVMS level hence the local "system" user must be specified. This user is translated depending on the language of the Windows distribution.
It is then highly recommended to install a English version of Windows to avoid issues with accents and non standard characters when creating this proxy.
Execute the same operations as described in chapter "Using rsh" for Tru64 or VMS to enable remote connection for the "SYSTEM" user.
This is case sensitive so for Tru64, specify "SYSTEM" and not "system" in the .rhosts file
It is highly recommended to test the execution of the script in check mode while connected as "system" account. To do so, use the psexec.exe program file provided in the kit or download it from the Microsoft Sysinternals page.
Open a cmd.exe window as Administrator and run the following command:
C:\WINDOWS\system32>C:\Charon\psexec.exe -i -s cmd.exe |
A new window will popup. To check you're connected as "system", run:
|
The run the Powershell script in check mode:
C:\WINDOWS\system32>powershell -file c:\charon\charon_cleanshutdown.ps1 -config c:\charon\myds20vms.ini -check |
then check the "RSH was successful" message is displayed followed by "Command successfully completed."
It is recommended to move the psexec.exe program file to a secured folder or to remove it when it is no more needed (check completed)
ssh mode preparation
Execute the same operations as described in chapter "Using ssh" for Tru64 or VMS to create a key pair with "SYSTEM" user with a different identity file.
To do so, use the psexec.exe program file provided in the kit or download it from the Microsoft Sysinternals page.
Open a cmd.exe window as Administrator and run the following command:
C:\WINDOWS\system32>C:\Charon\psexec.exe -i -s cmd.exe |
A new window will popup. To check you're connected as "system", run:
|
Remember to specify a different identity file in the .ini file. This can be done thanks to the "identityfsys" parameter (see: Using ssh)
The run the Powershell script in check mode:
C:\WINDOWS\system32>powershell -file c:\charon\charon_cleanshutdown.ps1 -config c:\charon\myds20vms.ini -check |
then check the "SSH was successful" message is displayed followed by "Command successfully completed."
It is recommended to move the psexec.exe program file to a secured folder or to remove it when it is no more needed (check completed)
Windows settings - Local group policy
Adding the script to the shutdown Powershell scripts
Open the "Local Group Policy Editor" (run gpedit.msc) and go to the Shutdown script setup:
Select the "Powershell Scripts" tab, click on the "Add..." button, specify the path to the charon_cleanshutdown.ps1 script and its parameters:
Display instructions in shutdown scripts as they run
It is recommended to enable the display instructions during shutdown to check the Charon Legacy OS shutdown is correctly performed.
Open the "Local Group Policy Editor" (run gpedit.msc) and go to the "Computer Configuration" → "Administrative Templates" → "System" → "Scripts" setup:
Enable this functionality and optionally leave a comment:
Specify maximum wait time for Group Policy scripts
By default the script executed at Windows shutdown have a default timeout of 10 minutes (600 seconds). It is possible to change this value in case the shutdown takes more time.
Open the "Local Group Policy Editor" (run gpedit.msc) and go to the "Computer Configuration" → "Administrative Templates" → "System" → "Scripts" setup:
Enable this functionality, define the new timeout and optionally leave a comment:
