Hi, We are running J2EE application using local X Server to draw some images. The problem is that X Server is using magic cookies to authenticate X clients. On some occasions the magic cookie is invalidated and then the application cannot communicate with the X Server. In man pages for xauth I found that the cookie could time out. The default is 60 seconds. Our app could be down for maintenance longer than a minute so that explains why the cookie gets invalidated. When that happens the only thing we can do is to restart X Server first and then our app to resolve the connection problem. Since our app is the only X client on the server I think it make sense to switch to host authentication for X Server. How do I configure X Server to use host authentication? f you think magic cookies are still better solution for X Server authentication please let me know how could we prevent their invalidation? I tried to use xauth to regenerate the cookies for the localhost display but with no success. xauth> generate :0 . trusted Xlib: connection to ":0.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key xauth: (stdin):8: unable to open display ":0". Any suggestion is appreciated. Unfortunately I was not able to find enough information on this topic, and the man pages don't help much.
