Even without the -X, -Y switches, my attempt failed. What does the 'no display speicified' error mean? P.S. The weird thing is that if I connect to the remote server through my PUTTY and repeat the command 'firefox' it works?!?!(firefox is displayed on local computer) P.S. my local computer is Windows 7 so I have Xming running on background in order to allow X11 display.

on remote server also gives the "cannot open display" error. Answer: You can fix the "cannot open display" error by following the xhost procedure mentioned in this article. 1. Allow clients to http://unix.stackexchange.com/questions/138936/why-wont-x11-display-work-through-ssh-login connect from any host using xhost+ Execute the following command to disable the access control, by which you can allow clients to connect from any host. $ xhost + access control disabled, clients can connect from any host 2. Enable X11 forwarding While doing ssh use the option -X to enable X11 forwarding. $ ssh username@hostname -X Enable trusted X11 forwarding, by using the http://www.thegeekstuff.com/2010/06/xhost-cannot-open-display -Y option, $ ssh username@hostname -Y 3. Open GUI applications in that host After opening ssh connection to the remote host as explained above, you can open any GUI application which will open it without any issue. If you still get the "cannot open display" error, set the DISPLAY variable as shown below. $ export DISPLAY='IP:0.0' Note: IP is the local workstation's IP where you want the GUI application to be displayed.
