2.6.2 Installation Using a Serial Console
For this installation method, you need a second computer that is connected by a null
modem cable to the computer on which to install SUSE Linux Enterprise Server. De-
pending on the hardware, even the firmware or BIOS of the computer may already be
accessible to the serial console. If this is possible, you can carry out the entire installation
using this method. To activate the serial console installation, additionally specify the
parameter console=ttyS0 at the boot prompt after the boot process has completed
and before the installation system starts.
On most computers, there are two serial interfaces, ttyS0 and ttyS1. For the installation,
you need a terminal program like minicom or screen. To initiate the serial connection,
launch the screen program in a local console by entering the following command:
screen /dev/ttyS0 9600
This means that screen listens to the first serial port with a baud rate of 9600. From this
point on, the installation proceeds similarly to the text-based installation over this ter-
minal.
2.6.3 Installation with SSH
If you do not have direct access to the computer hardware and, for example, the instal-
lation should be launched from a management console, control the entire installation
process over the network. To do this, enter the parameters UseSSH=1 and
SSHPassword=<secret> at the boot prompt. An SSH daemon is then launched in
the system and you can log in to the system as user root with the password "secret".
To connect, use the command ssh -X root@<ipaddr>.
If you do not have a DHCP server available in your local network, manually assign an
IP address to the installation system. Do this by entering the option
HostIP=<ipaddr> at the boot prompt.
As soon as you are logged in to the installation system, launch the actual installation
with the command yast for a text-based installation or yast2 to proceed with the
graphical installation. This then guides you through the installation. This procedure is
described in detail in
Section 14.1.5, "Simple Remote Installation via SSH—Dynamic
Network Configuration"
(page 195).
