Thanks to the responses from my other email thread: "Is there a way to display a message on the clients?2" I've been able to create a script to display a message on the DRBL clients. I have one more hurdle to cross though :) I set up a test DRBL Server (rather than use the live Server). I installed Jaunty and got DRBL up and running. My script worked fine on this setup, but when I moved to the live server I got the 'cannot open display error' with regards to the display. The live server is Hardy and the only difference I can see at the moment is the xhost setup. On the test DRBL client (using the Jaunty DRBL server) typing in xhost in a terminal I see the following entry: SI:localuser:<username> But on the live DRBL client (using the Hardy DRBL Server) running xhost shows no entries. If I do xhost +SI:localuser:<username> on the client then the script is able to display the message. I'm now wondering why the live DRBL client does not have an entry. I cannot remember doing anything different on the Jaunty DRBL server to the Hardy DRBL server. Is this because there is a difference between how Hardy and Jaunty works/installs itself or have I missed something? Thanks in advance. Regards, Tim. Have more than one Hotmail account? Link them together to easily access both. ------------------------------------------------------------------------------ Come build with us!

Both DRBL Servers are running the latest version of DRBL. I have found that my issue is nothing to do with DRBL. It's to do with how Jaunty and Hardy login a user differently. In Jaunty when a user logs in a script is run to add the user to xhost as SI:localuser:<username> whereas Hardy does not do this. The precise different under Jaunty is in the /etc/X11/Session.d. There is a file called 60x11-common_localhost which gets sourced by Xsession and somehow run (I'm still learning the nuts and bolts of Ubuntu :) ) when someone logs in. I guess on Hardy I could just use the copy of the same file. For any future installation of DRBL I think we'll be using Jaunty anyway. BTW although my remote messaging script is not perfect (or the prettiest :) ) is there a place I can publish it along with instructions to give access to it for the DRBL Community?
