→Requirements for Remotely Displaying Applications
Firstly, the system on which the application is to be displayed must be running an X server. If the system is a Mac OS X, UNIX or Linux based system with a desktop environment running then this is no problem. If the system is running Windows, however, then you must install an X server on it before you can display applications from a remote system. A number of commercial and free Windows based X servers are available for this purpose and a web search should provide you with a list of options.
Secondly, the system on which the application is being run (as opposed to the system which the application is to be displayed) must be configured to allow SSH access. Details on configuring SSH on a Fedora CentOS system can be found in the chapter entitled [[Configuring CentOS Remote Access using SSH]]. Finally, SSH must be configured to allow X11 Forwarding. To verify this, load the ''/etc/ssh/ssh_config'' file into an editor and make sure that the following directive is set:
<pre>
</pre>
Once the above requirements are met it is time to remotely display an application.
