Select this option if you have a dedicated line to the Internet. Your machine is online permanently, so no dial-up is required. If your system is part of a local network with a central e-mail server, select this option to ensure permanent access to your e-mail messages.

This item is relevant for users who have a computer at home, are not located in a network, and occasionally connect to the Internet.

If you do not have access to the Internet and are not located in a network, you cannot send or receive e-mail.

Use this module to configure the hostname and DNS if these settings were not already made while configuring the network devices. Also use it to change the hostname and domain name. If the provider has been configured correctly for DSL, modem, or ISDN access, the list of name servers contains the entries that were extracted automatically from the provider data. If you are located in a local network, you might receive your hostname via DHCP, in which case you should not modify the name.

When booting and in small networks, you can use Hostnames for hostname resolution instead of DNS. The entries in this module reflect the data of the file /etc/hosts. For more information, read Section 30.6.1.6, “ /etc/hosts ”.

If you have a Kerberos server in your network for network authentication, use Kerberos Client.

If using LDAP for user authentication in the network, configure the client in LDAP Client. Information about LDAP and a detailed description of the client configuration with YaST are available in Section 35.3, “Configuring an LDAP Client with YaST”.

With NFS client, mount directories provided by NFS server in your own file trees. Use NFS Client to configure your system to access an NFS server in the network.

If you run NIS server to administer user data on a central place and distribute it to the clients, configure the client here. Detailed information about NIS client and configuration with YaST is available in Section 33.1, “Configuring NIS Clients”.

NTP (network time protocol) is a protocol for synchronizing hardware clocks over a network. Information about NTP and instructions for configuring it with YaST are available in Chapter 32, Time Synchronization with NTP.

Configure the network services (such as finger, talk, and ftp) to start when SUSE Linux Enterprise boots using Network Services. These services enable external hosts to connect to your computer. Various parameters can be configured for every service. By default, the master service that manages the individual services (inetd or xinetd) is not started.

When this module starts, choose whether to start inetd or xinetd. The selected daemon can be started with a standard selection of services. Alternatively, compose your own selection of services with Add, Delete, and Edit.

	Configuring Network Services (xinetd)
The composition and adjustment of network services on a system is a complex procedure that requires a comprehensive understanding of the concept of Linux services. The default settings are usually sufficient.

Configure Internet proxy client settings in Proxy. Click Enable Proxy then enter the desired proxy settings. You can test these settings by clicking Test Proxy Settings. A small window informs you whether your proxy settings work correctly. After your settings have been entered and tested, save them by clicking Accept.

To administer your machine remotely from another machine, use Remote Administration. To maintain your system remotely, use a VNC client, such as krdc, or a Java-enabled browser. Although remote administration using VNC is simple and fast, it is less secure than using SSH, so you should always keep this in mind when using a VNC server. Find detailed information about installing with a VNC client in Section 4.1.1, “Simple Remote Installation via VNC—Static Network Configuration”.

Allow remote administration by selecting Allow Remote Administration in Remote Administration Settings. Selecting Do Not Allow Remote Administration disables this function. Click Open Port in Firewall to allow access to your computer. Clicking Firewall Details displays network interfaces with open ports in the firewall. Select the desired interface and click OK to return to the main dialog. Click Accept to complete the configuration.

The YaST Remote Administration module is highly recommended for configuring VNC on your machine. Although the SaX2 interface also allows you to set remote access properties, it is not a substitute for YaST. It only enables you to configure your X server as a host for VNC sessions.

Use Routing to configure the paths data takes over the network. In most cases, only enter the IP address of the system through which to send all data in Default Gateway. To create more complicated configurations, use Expert Configuration.

In a heterogeneous network consisting of Linux and Windows hosts, Samba controls the communication between the two worlds. With the Samba Client module, you can configure your computer as member of a Windows domain. Find information about Samba and the configuration of clients in Chapter 36, Samba.
