I just upgraded my machine to FC4 and am having a few issues. I administer some Solaris9 servers running NetBackup. In FC3, I could either SSH or telnet to the Sun machines, issue an "export DISPLAY=myipaddress:0.0" and then start a Java GUI. In FC4 I get "Cannot connect to display". To assure myself that I was not imagining anything, I tried xclock with the same result. I also administer about 12 RH AS3 & 4 servers but did not have the same problem. I'm wondering if this has anything to do with Java or the version of X- Windows. If anyone has resolved this issue, please let me know what you did. Thanks, Ed
