Adding parameters to DefaultShell in Windows OpenSSH Server (e.g. powershell.exe)
Windows OpenSSH Server is a powerful open source SSH server for Windows that allows users to securely connect to any system. It supports a wide range of authentication methods, including public key authentication, password authentication, and Kerberos authentication. It also supports a variety of protocols, including SFTP, SCP, and SSH.
One of the most powerful features of Windows OpenSSH Server is the ability to customize the user's environment. This is done by setting the DefaultShell in the sshd_config file. By default, the DefaultShell is set to \cmd.exe\. This allows users to start a regular cmd.exe session, but it can be changed to any other valid shell, such as PowerShell.
PowerShell is a powerful scripting language that allows users to automate tasks, manage systems, and much more. It is a powerful tool, and many IT administrators prefer to use PowerShell instead of cmd.exe for managing Windows systems. However, it can be difficult to set up PowerShell as the DefaultShell in Windows OpenSSH Server.
The first step is to make sure that PowerShell is installed and available on the system. If it is not, it must be installed before it can be used. Once PowerShell is installed, the sshd_config file must be edited to set the DefaultShell to \powershell.exe\. This will tell Windows OpenSSH Server to use PowerShell instead of cmd.exe when a user logs in.
In addition to setting the DefaultShell to \powershell.exe\, it is also possible to add additional parameters to the command. These parameters can be used to customize the PowerShell session for the user. For example, the \-command\ parameter can be used to run a specific command when the user logs in. This can be used to set up the user's environment or to run a specific script.
It is also possible to use the \-file\ parameter to specify a PowerShell script file that will be run when the user logs in. This is a powerful feature that allows IT administrators to automate tasks, such as setting up the user's environment, when they log in.
Finally, it is possible to use the \-ExecutionPolicy\ parameter to specify the execution policy for the PowerShell session. This can be used to ensure that only trusted scripts are run, and to prevent malicious scripts from being executed.
By taking advantage of the powerful features of Windows OpenSSH Server, IT administrators can use PowerShell to securely manage Windows systems. Setting the DefaultShell to \powershell.exe\ is easy, and it is also possible to add additional parameters to the command to customize the user's environment. By taking the time to customize the user's experience, IT administrators can ensure that users are able to securely and effectively manage Windows systems.
