Chapter 5. Native Linux on pSeries 127
In case you have Linux running on your desktop instead of Windows, PuTTY is
not needed, as most Linux systems come with a working ssh client installed (see
http://www.openssh.org/ for the most common implementation.)
Virtual desktops with VNC
VNC stands for Virtual Network Computing. It is, in essence, a remote display
system that allows you to view a desktop environment not only on the machine
where it is running, but from anywhere on the Internet and from a wide variety of
machine architectures. For further information and to download the appropriate
client for your desktop system, see:
All newer VNC servers provide access via HTTP. A small Web server runs on
is the display number of the virtual display. This means that
you are able to connect to your VNC session by pointing any Java-capable
browser to http://hostname:5801/. As the VNC server comes preinstalled on
SuSE Linux for pSeries, no download or installation on your client system is
5.2.3 Systems without a graphics adapter
To simulate a system without a graphics adapter, such as the entry rack model
p610 6C1, we simply disconnect the display of our deskside p610 6E1 and
switch to a serial console using the procedure described in this section.
A serial cable has to be connected to a serial port of the pSeries and a terminal
attached. Using a null modem cable, a normal PC can run a terminal emulation
program, such as HyperTerminal (which is included in Windows) or minicom
under Linux. To use HyperTerminal, make sure that the correct COM port,
terminal type VT100, and 9600 Bits per second are selected.
Next switch the pSeries console by using the SMS Utilities menu. When
selecting Console in this menu, the terminal or terminal emulation has to be
physically connected already. Now the console has to be selected by pressing a
number, as indicated on the new console. After a successful switch to the new
serial console, the graphics display can be disconnected. An analogous
procedure can be used to switch back to the graphical console.
Installing SuSE Linux
To install Linux on a system with a serial console, only a few steps are different
from what was described in “Systems with a graphics adapter” on page 120.
