Hello Nicola, Patrick, et al


  The DTU *resets* (i.e. restarts the firmware from scratch) on a 

few occasions such as the power surge and loss of connectivity to 

the server with a 1-2 minute timeout, and that can be managed by 

ARP, router or firewall tweaking as Bob Doolittle suggested recently.


  A simple restart of the session (killing the X server, ending the

last critical Kiosk app) should only cause a search for an avilable

session (creation of a session) on the Sun Ray servers. The firmware

still uses the same IP settings, list of servers, etc. so it's not

truly resetting at this point.


  What I did not get from this thread, why is it critical to *reset*

the DTU? Should some USB-attached hardware or a display re-initialize?


  As a side note, if the budget permits, you could try to go with

a managed Rack PDU (i.e. an APC AP7920). These neat boxes allow you

to log in remotely (including a scriptable CLI) and reset the power 

receptacles. Alternatively (and cheaper) you can get a small UPS 

with a serial or USB management, and try to use NUT (Network UPS

tools) to trigger a shutdown of the UPS. At least the Powercom ones

I had in campus long ago, powered back up as soon as they detected

line voltage - and that was a matter of a few seconds.

I need to reset a specified Sun DTU without disconnect then reconnect the power cord. 

The power cycle which DTU's files involves?

If I know these files I can remove them with a script when a kiosk user close

an application. 

 

Set your application 'critical' in the Kiosk configuration. When the application is closed, the dtu will reset.
