How to Prepare for Installation Using a Remote Display

1. Type the following command on both the source computer and the display computer:

   % hostname

   The hostnames are used in subsequent steps.

2. Type the following command on the display computer:

   % xhost + source-computer-name

   Replace source-computer-name with the output of the hostname command entered on the source computer, which is the computer that contains the downloaded files.

   The xhost command enables programs running on the source computer to send their displays to the X server on the display computer.

3. Log in to the source computer using ssh -X and become superuser (root)

   You can use ssh with the -X option to forward the X display content back to the display computer. The source computer might not allow remotely logging in as root, so you might need to log in using your own username and become root after connecting to the source computer as shown below.

   % ssh -X source-computer-name
   Password: your password-on-source-computer
   % su
   Password: root-password-on-source-computer

4. On the source computer, set your DISPLAY variable to the display computer.

   If you use the C shell, type:

   # setenv DISPLAY display-computer-name:n.n

   If you use the Bourne shell, type:

   # DISPLAY=display-computer-name:n.n
   
   # export DISPLAY

   If you use the Korn shell, type:

   # export DISPLAY=display-computer-name:n.n

   Replace display-computer-name:n.n with the output of the hostname command entered on the display computer.

   You can type echo $DISPLAY on the display computer to see the display number, such as :2.0
