VNC (virtual network computing) is a client-server solution that allows a remote X server to be managed via a slim and easy-to-use client. This client is available for a variety of operating systems, including Microsoft Windows, Apple's MacOS, and Linux.
The VNC client, vncviewer, is used to ensure the graphical display and handling of YaST during the installation process. Before booting (IPL) the system to install, prepare a remote computer so it can access the system to install over the network.
As described in the Architecture-Specific Information manual, it is only necessary to choose the VNC connection option in the installation process for S/390 and zSeries. This option allows any VNC client to be connected to the installation system and ensures that the installation process can be carried out with the graphical YaST. ▪
To perform a VNC installation, pass certain parameters to the kernel. This must be done before the kernel is launched. To do this, enter the following command at the boot prompt:
vnc=1 vncpassword=<xyz> install=<source>
vnc=1 signals that the VNC server should be launched on the installation system. vncpassword is the password to use later. The installation source (install) can either be specified manually (enter the protocol and URL for the directory concerned) or it can contain the instruction slp:/. In the latter case, the installation source is automatically determined by SLP query. Information about SLP is contained in Section 21.6. “SLP Services in the Network”.
The connection to the installation computer and the VNC server running on it is established via a VNC client. Under SUSE LINUX, use vncviewer. This is part of the XFree86-Xvnc package. To establish a connection to the installation system from a Windows client, install the tightvnc program on the Windows system. This program is on the first SUSE LINUX CD, in the /dosutils/tightvnc directory.
Launch the VNC client of your choice. Then, when prompted, enter the IP address of the installation system along with the VNC password.
Alternatively, establish VNC connections using a Java-capable browser. To do this, enter the following into the address field of the browser:
http://<IP address of the installation system>:5801/
Once the connection has been established, YaST launches and the installation can start.
