This is the second article I've seen on how to get the screenshot of a remote machine and the second time I've tried it and failed. I get this error message...


kCGErrorIllegalArgument : initCGDisplayState: cannot map display interlocks.
kCGErrorIllegalArgument : CGSNewConnection cannot get connection port
screencapture: failed to make a connection to the windowserver


Any ideas? Firewall issue? I don't know.

    In order for open, screencapture, or osascript to work over ssh, you must have either ssh'd in as the user currently running, or you must run them with sudo.
