Installation Using X11 Forwarding; Installation Using Vnc; Installing From A Hard Drive (Dasd) - Red Hat ENTERPRISE LINUX 3 - INSTALLATION GUIDE FOR IBM S-390 AND IBM ESERVER ZSERIES Installation Manual

12
To run the graphical installation, use a workstation that has an X Window System server or VNC
client installed. Use an SSH client that allows X11 forwarding or a Telnet client. SSH is strongly
recommended for its security features as well as its ability to forward X and VNC sessions. Enable
X11 forwarding in your SSH client prior to connecting to the Linux image (the Linux guest running
on z/VM).

2.3.1. Installation using X11 Forwarding

For example, to connect to the Linux image and display the graphical installation program using
OpenSSH with X11 forwarding on a Linux workstation, type the following at the workstation shell
prompt:
ssh -X linuxvm.example.com
The option enables X11 forwarding.
-X
The graphical installation program cannot be started if your DNS or hostnames are not set correctly,
or the Linux image is not allowed to open applications on your display. You can prevent this by setting
a correct
DISPLAY=
eter file, replacing workstationname with the hostname of the client workstation connecting to
the Linux Image. Allow the Linux image to connect to the workstation using the command
on the local workstation.
+linuxvm
If the graphical installation via NFS does not automatically begin for you, verify the
able settings in the
parm
file on the reader. Additionally, make sure when performing an X11 forwarded display that the
parm
X server is started on the workstation machine. Finally, make sure the NFS installation method is
chosen, as this is the only method that supports graphical installations.

2.3.2. Installation using VNC

If you are using VNC, a message on the workstation SSH terminal prompts you to start the VNC client
viewer and details the VNC display specifications. Enter the specifications from the SSH terminal into
the VNC client viewer and connect to the Linux image to begin the installation.
Once you have logged into the Linux image the

2.4. Installing from a Hard Drive (DASD)

Note
DASD installations only work from ext2 or ext3 file systems. If you have a file system other than ext2
or ext3 you will not be able to perform a DASD installation.
Additionally, if a file called
