question

All-

I finally had time to circle back to this and in case someone needs this information in the future, here is what I found out and what we implemented to make sure someone couldn't just add a screen to our units and gain access.

1. You cannot set the screen to the tile interface mode with TouchEnabled = 0.

2. The value of Settings/Gui/DefaultOverview contains the last screen you were on in the Pages display mode. I set this value to OverviewHub.

3. The value of Settings/Gui/StartWithMenuView = 0 will enable Pages display mode. If this is set to one you'll drop directly to the Device List.

4. The value of Settings/Gui/TouchEnabled = 1 initially in order to kill the gui and allow the above changes to take effect. Sleep for 10-15 seconds and then set to 0.

5. We set one of the digital inputs so a field tech can override if needed locally.

------------------------------------------------------------------------------

So, I developed a script to do the following:

- set TouchEnabled = 0, Set DefaultOverview = OverviewHub and StartWithMenuView = 0

- kill gui (must be root to do this)

- sleep 20 seconds, set TouchEnabled = 1

------------------------------------------------------------------------------

I run this initially as root from /etc/rc.local and I have a crontab entry the runs hourly. So far, this works for everyone and I do have monitoring software checking the status of those settings so if someone is in there we know it. The good part is we are still able to remotely access the console and navigate using the virtual touchpad. Hope this is helpful.
