Network Configuration - Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 08-05-2008 Installation Manual

SUSE Linux Enterprise can use the DES, MD5, or Blowfish encryption algorithms for
passwords. The default encryption type is Blowfish. To change the encryption type,
click Expert Options > Encryption Type and select the new type.
The root can be changed any time later in the installed system. To do so run YaST
and start Security and Users > User Management.
3.14.2 Hostname and Domain Name
The hostname is the computer's name in the network. The domain name is the name of
the network. A hostname and domain are proposed by default. If your system is part
of a network, the hostname has to be unique in this network whereas the domain name
has to be common to all hosts on the network.
In many networks, the system receives its name over DHCP. In this case it is not nec-
essary to modify the hostname and domain name. Select Change Hostname via DHCP
instead. To be able to access your system using this hostname, even when it is not
connected to the network, select Write Hostname to /etc/hosts. If you often change
networks without restarting the desktop environment (e.g. when switching between
different WLANs), do not enable this option, because the desktop system may get
confused when the hostname in /etc/hosts changes.
To change hostname settings at any time after installation, use YaST Network Devices
> Network Card. For more information, see
Card with YaST" (page 561).

3.14.3 Network Configuration

TIP: IBM System z: Network Configuration
For the IBM System z platforms, a working network connection is needed at
installation time to connect to the target system, the installation source, and
the YaST terminal controlling the process. The steps to set up the network are
discussed in the network configuration chapter of the Architecture-Specific In-
formation manual (Chapter 2, Preparing for Installation (↑Architecture-Specific
Information)). The IBM System z platforms only support the types of network
interfaces mentioned there (OSA Token Ring, OSA Ethernet, OSA Gigabit Eth-
ernet, OSA Express Fast Ethernet, Escon, IUCV, and OSA Express High-Speed
