Configure SSH with X11 Forwarding

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.
(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
```
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
```
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.
