Policy CSP - RemoteShell

Tip

This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.

The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

This policy setting configures the maximum time in milliseconds remote shell will stay open without any user activity until it's automatically deleted.

Any value from 0 to 0x7FFFFFFF can be set. A minimum of 60000 milliseconds (1 minute) is used for smaller values.

  • If you enable this policy setting, the server will wait for the specified amount of time since the last received message from the client before terminating the open shell.

  • If you don't configure or disable this policy setting, the default value of 900000 or 15 min will be used.

./Device/Vendor/MSFT/Policy/Config/RemoteShell/SpecifyMaxMemory

This policy setting configures the maximum total amount of memory in megabytes that can be allocated by any active remote shell and all its child processes.

Any value from 0 to 0x7FFFFFFF can be set, where 0 equals unlimited memory, which means the ability of remote operations to allocate memory is only limited by the available virtual memory.

  • If you enable this policy setting, the remote operation is terminated when a new allocation exceeds the specified quota.

  • If you disable or don't configure this policy setting, the value 150 is used by default.
