Hello Is it possible to disable X authentication but still using X11 forwarding? The reason why I need this is that I come from outside via ssh into a secure network environment and call an X11 application. With this application I am able to monitor other applications within the secure network and call if necessary the X11 interfaces of these applications via rsh. And this is where the problem starts I constantly received the following error: X11 connection rejected because of wrong authentication at ... I then added to the monitoring application the following line just before doing the rsh: xauth extract - $DISPLAY | rsh <hostname> xauth merge - This did solve the problem for some hosts but not all. The problem is that the hosts where it does not work cannot find xauth when calling it via rsh. I also have tried to use xrsh instead of rsh, but this did not solve the problem. Another problem is that everything is much slower. The merging of the cookies sometimes takes quit some time. So is this possible to just disable X authentication but still use the X11 forwarding feature? Holger
