Remotely Configuring Mac Teacher Console after Installation

Remotely Configuring Mac Teacher Console after Installation

Overview

If changes need to be made to the LanSchool Teacher Console settings after installation is complete, the lstconfig utility is a tool that can be used to aid in the remote configuration. The lstconfig utility is provided in the installation media under Mac>> Utilities folder.

Using the lstconfig Utility

This utility can be used in conjunction with ARD. 
Run this tool using sudo in order to change global settings for this device. Otherwise, run lstconfig as user to change Teacher-specific settings.

Usage: lstconfig <key> <newvalue> 

The following is an example to allow the Teacher to change channels: 

sudo ./lstconfig EnableChannelSelect true 

Value names are case-sensitive.
