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

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.

shutdown function from run_ltspinfod and give it to a seperate command
with higher permissions?

yes, I know. I already did it.

What if you change the permission of ltspinfo to 754?
