How to launch application with the rights of another user

[MACAWI]

With X11 forwarding, it is possible to run graphical applications remotely through an ssh connection.

However, if you want to launch applications with the rights of another user, this will not work
(eg by the user tries to run homeadmin gedit with the user's stone).

homeadmin Totor @: ~ $ sudo su stone
[sudo] password for homeadmin:
pierre @ foo: / home / $ gedit homeadmin
PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
(gedit: 3239): Gtk-WARNING **: can not open display: localhost: 10.0
pierre @ foo: / home / $ homeadmin

Simply copy your file precondition. Xauthority in the user directory:

sudo cp ~ /. Xauthority / home / peter
sudo su stone

and then you can run graphical applications with the rights of Peter.

The cookie will be invalidated as soon X11 disconnect your ssh session.
