[HOWTO] iSightCapture Command Line Security Workaround

[Tex-Twil]

Hello,
tried the AppleScript hac but it doesn't work either:

do shell script "/Users/me/webcam/isightcapture test.jpg"

$ open /Users/me/webcam/script.app
LSOpenFromURLSpec() failed with error -10828 for the file /Users/me/webcam/script.app.

any ideas ?

How did you build your application?

LaunchServices/LSInfo.h has:

Error -10828
kLSNoClassicEnvironmentErr = The Classic emulation environment was required but is not available.

Looks like you are trying to run a Classic type application on 10.5.

There is nothing I built. The application is just the one line script posted on the beginning.

edit: ok I think Im a noob with Apple Script. In the how to is written "Open Script Editor and type in:". I just edited a new file using vim so I guess my error is here.

Do I have to build the application ? how can I do it via command line ?

EDIT2: I've tried this way:

do shell script "/Users/me/webcam/isightcapture test.jpg"

then

osascript script.txt

but it says again

script.txt:0:76: execution error: FATAL: setting data channel failed - cam busy/not connected ? (1)

EDIT3: ouff Finally I set up a VNC server to my MacBook Pro and created the Application using the Script Editor. It works great

So wait, you edited those with VIM and not ScriptEditor of AppleScript?

/Applications/AppleScript/ -> open Script Editor

and replace the /Users/me parts with your username in place of me

Yes that's what I did first cos I was connected to my mac only via ssh. But it's now fixed. see my previous post EDIT3.

Over SSH

1. get process ID loginwindow "sudo killall -s loginwindow" return $PID
2. "sudo launchctl bsexec $PID isightcapture -t jpg /file.jpg"

-EXAMPLE----
sudo killall -s loginwindow
kill -TERM 35
sudo launchctl bsexec 35 isightcapture -t jpg /file.jpg
-------------------------------

WORK!!!

from screencapture
SECURITY CONSIDERATIONS
To capture screen content while logged in via ssh, you must launch screencapture in the same mach boot-strap bootstrap
strap hierarchy as loginwindow:

PID=pid of loginwindow
sudo launchctl bsexec $PID screencapture [options]

Sorry for my english

there's no need for creating gui apps or scripts, here's a workaround:
connect to remote host via ssh, then type:
ps ax | grep [l]oginwindow
output will look something like
1381 ?? Ss 0:01.36 /System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow console

The PID is the first number in the output; now type
sudo launchctl bsexec 1381 isightcapture -t png /somepic.png

and voila
