Thanks for the emails I was running the 'xhost +' before, just forgot to mention it. This time I did use the ssh -X command from the xterm to go to the sun server. Before I was using a separate ssh client to log into the Sun server. After logging in I noticed a message that said an entry was added into the /home/<username>/.Xauthority file. I ran xclock again and then it came up on my laptop without any errors, I did not have to set my DISPLAY variable. I then did a sudo into the oracle user on sun to kick off the installer. The installer made me set DISPLAY. After starting the installer it eventually through the error: Can't connect to X11 window server 'my IP address:0.0' as the value of the DISPLAY variable. I could see the following with netstat -a <sun server>.55671 <my PC>.6000 0 0 24820 0 SYN_SENT Thanks for the help so far _____ This electronic message transmission is a PRIVATE communication which contains information which may be confidential or privileged.
