Network Configuration - Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual

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 Section 30.4.1, "Configuring the Network
Card with YaST" (page 565).

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
Token Ring). The YaST dialog simply displays the interface with its settings as
already configured. Just confirm this dialog to continue.
By default, Traditional Method without NetworkManager Applet is enabled. If desired,
you can also use NetworkManager to manage all your network devices. However, the
traditional method is the preferred option for server solutions. Find detailed information
about NetworkManager in Section 30.6, "Managing Network Connections with Net-
workManager" (page 584).
This configuration step also lets you configure the network devices of your system and
make security settings, for example, for a firewall or proxy. To configure your network
connection later, select Skip Configuration and click Next. Network hardware can also
be configured after the system installation has been completed. If you skip the network
device configuration, your system is left offline and is unable to retrieve any available
updates.
