Locking OS x remotely

[Newbify2]

Is there a way to lock a remote os x machine remotely through the terminal. This way one can update the machine without users using it and then reboot the machine.
Thanks

Yep.

/System/Library/CoreServices/Menu\ Extras/User.menu/Contents/Resources/CGSession -suspend

It brings you to the login window. I'm not sure if this works remotely, but it "should."

tried this remotely and it didn't work. Any other ideas?

 

[Black Morty Rackham]

Did it work locally?

 

[Newbify2]

Yes it works locally. I want to be able to prevent logging into the system.

 

[Black Morty Rackham]

How are you connecting to the system? SSH?

 

[Newbify2]

Yes SSH

'shutdown -k' might be what you are looking for. just 'man shutdown' to see. otherwise you might just have to run an applescript to do it.

tell application "loginwindow"
