Works from a cron job: 44 11 * * * /root/tmp/tmp/testg Here is my setup: I have vncserver running on my server. I open root's desktop with vncviewer from another PC. From the same "another PC", I ssh in and can run the script which starts galeon and the window opens in vncviewer. (I only use the real console in emergencies.) The ssh terminal does not have the environment variable DISPLAY set; thus emulating the environment of cron jobs. This setup also works if the script is run from cron. I tested it here. I'm not sure what you guys are talking about when you say security settings. The "another PC" is on my local LAN and the server allows a connection. [EMAIL PROTECTED] tmp]# cat testg #!/bin/sh export DISPLAY=:0.0 echo $DISPLAY /usr/bin/galeon #/usr/bin/mozilla Root gets an email from the echo command which reads: :0.0 HTH, Bill
