xwd command to screenshot Pi display

[dil15]

Hi I have been working on this following website :http://colesec.inventedtheinternet.com/hacking-x11/ to secretly capture the Desktop screenshot of Pi.

When I type:

Code: Select all

xwd -root -screen -silent -display 192.168.1.5:0 > screenshot.xwd

It shows me an error with

Code: Select all

Invalid mit-magic-cookie-1 keywd: unable to open display 'IP:0'

Does anybody have any idea??

There are luckily (some) security in X that prevents unauthorized users to access your desktop.

If you on the other hand are trying to do this on the desktop you are logged in to, then don't use the ip-adress, just use "-display :0.0".

To allow remote connections to a X-windows environment look up "xhost" command.
