[K12OSN] Shutting clients down: was tight vnc connection to ltsp client refused (111 error)

[Angus Carr]

Could you not set up a cron job which fires off a local program on the 
terminal?
ssh -l root ${TERMINAL} haltsys

As long as there is appropriate keying, and the keys in use don't have 
passphrases, it should be no problem.

I keep thinking an automated shutdown with our kiosk terminals would be 
great. I keep meaning to set up the automatic turning on features, too, 
but I'm not sure I want to. I'd have to send the wake on lan magic 
packet, but my terminals (Old Dell's) aren't responding. One day, I will 
figure it out, but that day is not today.
