RemoteShell/AllowRemoteShellAccess

cross mark check mark check mark check mark check mark cross mark cross mark

Scope:

  • Device

This policy setting configures access to remote shells.

If you enable or do not configure this policy setting, new remote shell connections are accepted by the server.

If you set this policy to ‘disabled’, new remote shell connections are rejected by the server.

Tip

This is an ADMX-backed policy and requires a special SyncML format to enable or disable. For details, see Understanding ADMX-backed policies.

You must specify the data type in the SyncML as <Format>chr</Format>. For an example SyncML, refer to Enabling a policy.

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.

Scope:

  • Device

This policy setting configures the maximum number of users able to concurrently perform remote shell operations on the system.

The value can be any number from 1 to 100.

If you enable this policy setting, the new shell connections are rejected if they exceed the specified limit.

If you disable or do not configure this policy setting, the default number is five users.

RemoteShell/SpecifyIdleTimeout

cross mark check mark check mark check mark check mark cross mark cross mark

Scope:

  • Device

This policy setting configures the maximum time in milliseconds remote shell will stay open without any user activity until it is 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 do not configure or disable this policy setting, the default value of 900000 or 15 min will be used.

RemoteShell/SpecifyMaxMemory

cross mark check mark check mark check mark check mark cross mark cross mark

Scope:

  • Device

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 do not configure this policy setting, the value 150 is used by default.
