Hi all,

i am using ubuntu 11.04

I have a python script running as a service. I started it like "sudo service python_script start"

I want to take screenshot any login user. i tried to run "import -window root /tmp/screenshot.png" command in my python_script but no reaction. Also tries 'su active_user -c import -window root /tmp/screenshot.png nothing changed.

there is no problem when I run it like "sudo python_script" when logged in as a user but when i run it like service there is no reaction.

How can i achieve this ? There is a way ?

Thnks

it can be any other script only i want to take active user screenshot.

probably the script has no access to the current DISPLAY environment.

thnks for replay pan64

coming a signal from outside to my script and just running below ;

cmd ='import -window root /tmp/screenshot.png'
out = commands.getstatusoutput(cmd)
logging.debug(out)

or

cmd ='su ' + active_user + " -c 'import -window root /tmp/screenshot.png'"
out = commands.getstatusoutput(cmd)
logging.debug(out)

script acting like root but the active user is not root so script cant take screenshot.

Do you know pan64 how can i access to current DISPLAY ? How can i give the this access authority to script

the script should be started by the user, so try setuid

if the script runs by logged user, there is no problem ok but it is not solve my problem

why not? you will start a process, change user id (with setuid) and start this process
