You use a COBOL Application debug configuration to debug projects developed on a remote UNIX machine. Before you can debug
                  the remote application, you need to have an X window implementation installed and running, so that the output of a remote
                  application running on a UNIX machine can be viewed on your local machine. You do not need X window for other debug configuration
                  types. 
                  		
               
                
                  		
                  Ensure the local X11 server can receive connections from the remote machine. You can do this using the 
                     		  
xhost + command or by enabling SSH port forwarding. Alternatively, enable TCP/IP connections for X11 by setting a value in a configuration
                     file in a manner appropriate to your operating system. For example: 
                     		
                     
 
                        		  
                        - Red Hat: run the 
                           			 gdmsetup utility and deselect 
                           			 Deny TCP connections to Xserver in the Security tab (this configures 
                           			 DisallowTCP=false in /etc/gdm/custom.conf) 
                           		  
                        
- SUSE: set DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes" in 
                           			 /etc/sysconfig/displaymanager 
                           		  
                        
  
                
                  		
                  Specify the details about the display that the X11 server tries to contact in the IDE preferences as follows: 
                     		
                  
 
                  		
                   
                     		  
                     - Click 
                        			 Window > Preferences > Micro Focus > Debug. 
                        		  
                     
- Type the display details in the 
                        			 Default X Server (DISPLAY) field. 
                        			 
                        The default 
                           				Default X Server (DISPLAY) value is 
                           				clientMachineName:0.0.
