Turning off PC with Telnet-script

[Ola Stenstrom]

I'm running a show with several WatchOut-computers remotely triggered
by Qlab thru Applescript/Telnet commands. I'm wondering:
is there is any way to remotely shutdown every PC with a telnet
command?
...they are placed in very hard to reach places :-/

SSH could be used to do this fairly easily, at least for Unix based systems like OS X and Linux.  I wouldn't want to use Telnet for it due to it's unencrypted nature and you want any shutdown command to require a login, especially if it is on a network in my opinion.

Windows has a 'shutdown' command that you can run from the command prompt; use 'shutdown /?' to view all its options. I assume that once you install an SSH or Telnet server on each PC, you should be able to trigger that command easily.

Can't you just log in via VNC and shut them down remotely?  Starting up remotely may be a different proposition...

OS X has the standard unix 'shutdown' and 'halt' commands. Which can be
run using whatever remote shell you like. However you probably dont
want to do do this you probably want to make the machine sleep.

In order to do this you'll need an Apple Script which tells the system
to sleep ie something like

tell application "System Events"
sleep
end

(I think this still works but I last tried it on 10.3)

Then you want to use wakeonlan to wake the machines up later.

Ah- I thought WatchOut had switched over to PC only?

That would be a simple and easy way to go about it.  Many PCs can be set up to boot up as soon as they have mains power.  But you would have to do some digging to make sure that setting is available in the bios.  It’s not something you will find in all PCs.

 

I would not recommend putting them to sleep.  A full reboot is always preferable in my book.

 

If you need to automatically start up software after the machine boots, I would recommend a program from R2 Studios called Start Up Delayer.  It allows you to control what software starts during boot up and in what order and allows for easy setting of delay times between each application loading.  Very handy for systems that need to start up and do things all on their own.
