Configure SSH with X11 Forwarding

1. You can use either the -X or -Y flag to enable X11 forwarding through SSH when you log in as the root user. For example:

   ssh –Y root@server-name

   Note:

   If you do not have DNS on your server or the server name does not work, enter the IP address of the server.
2. (Optional) Install the xorg-x11-xauth package (if it is not already installed). For example:

   yum install xorg-x11-xauth
   yum install xorg-x11-utils

3. You can use either the -X or -Y flag to enable X11 forwarding through SSH when you disconnect and log in as the oracle user. For example:

   ssh -Y oracle@vm

4. Find the values for the DISPLAY variable with the xauth list command.

   $ xauth list
   <domain name>/unix:12
   <domain name>/unix:11
   <domain name>/unix:10

   In the example above, either 12, 11, or 10 are suitable values for the DISPLAY variable.
