[Ilugc] Xmessage in SUSE
I am building a custom application which starts in roots cron every day. I am using Xmessage to alert the user that the application is completed running. It should alert all the user who have logged in via a popup. The problem i am having is that its not getting appeared in popup. If the same script is made run on console then i am getting this popup. What is the reason for that. How it can be solved. -- regards Rajesh Kumar R.K ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

You will have to set the DISPLAY environment variable to the right display number. Something like 'export DISPLAY=:0' before running the script.

I can be localhost:0 as well if your localhost has an Xserver.

X has an authentication mechanism between the X server and the client. The shared secret MIT MAGIC COOKIE is stored in the xauthority file which is accessible only by the local user who has started the X session. If you want to applications launched by your cron job to communicate to X sessions of other users, you will have to bypass the X session security mechanisms. Not a recommended practice. - Raja ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Sidebar question to OP - can it not be done via a simple email? I guess your objective is to notify the users that the job is completed. -- Arun Khan ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
