Dear all, Fist I apologize for my bad english. I use the Fedora Core3. I want to use the graphical interface of remote workstation. I do as following: 1) In my computer: xhost + 2) I use ssh command to connect the remote workstation I use the command like: setenv DISPLAY xxx.xxx.xx.xx(my IP):0.0 But I still cannot use the graphical interface. The warning information indicates that it unable to open display. What is the wrong? what can I do for this problem?
