20 Start-Up 1.9.2 root Password root is the name of the superuser, the administrator of the system. Unlike regular users, which may or may not have permission to do certain things on the system, root has unlimited power to do anything: change the system configuration, install programs, and set up new hardware. If users forget their passwords or have other problems with the system, root can help. The root account should only be used for system administration, maintenance, and repair. Logging in as root for daily work is rather risky: a single mistake could lead to irretrievable loss of many system files. For verification purposes, the password for root must be entered twice. Do not forget the root password. Once entered, this password cannot be retrieved. WARNING: The root User The user root has all the permissions needed to make changes to the system. To carry out such tasks, the root password is required. You cannot carry out any administrative tasks without this password. 1.9.3 Network Configuration You can now choose whether to use NetworkManager or the traditional method to manage all your network devices. NetworkManager is the new tool enabling automatic connection establishment with minimal user intervention. It is ideal for mobile computing. Also configure the network devices of your system and make security settings, for example, for a firewall or proxy. To configure your network hardware at this stage, refer to Section “Configuring a Network Connection with YaST” (Chapter 18, Basic Networking, ↑Reference). Otherwise, select Skip Configuration and click Next. Network hardware can also be configured after the system installation has been completed. NOTE: Network Devices and Update If you skip the network device configuration, your system will be offline and unable to retrieve any available updates or include them in the installation.
As well as device configuration, configure network accessibility–related settings: Firewall Configuration When you connect to a network, a firewall is started automatically on the configured interface. The configuration proposal for the firewall is updated automatically every time the configuration of the interfaces or services is modified. To adapt the automatic settings to your own preferences, click Change → Firewall. In the dialog that opens, determine whether the firewall should be started. If you do not want the firewall to be started, select the appropriate option and exit the dialog. To start and configure the firewall, click Next for a series of dialogs similar to those described in Section “Configuring with YaST” (Chapter 4, Security in Linux, ↑Reference). VNC Remote Administration To administer your machine remotely by VNC, click Change → VNC Remote Administration, enable remote administration, and open the port in the firewall. If you have multiple network devices and want to select on which to open the port, click Firewall Details and select the network device. You can also use SSH, a more secure option, for remote administration. Proxy If you have a proxy server in your network to control access to the network, enter the server name and all other required information to enable access to the Internet. Internet Connection Test If you have configured an Internet connection, you can test it now. For this purpose, YaST establishes a connection to the SUSE Linux server and checks if any product updates are available for your version of SUSE Linux. If there are such updates, they can be included in the installation. Also, the latest release notes are downloaded. You can read them at the end of the installation. To start the test, select Yes, Test Connection to the Internet and click Next. In the next dialog, view the progress of the test and the results of the test. If the test fails, click Back to return in the previous dialog and correct the configuration or skip the test. If you need more information about the test process, click View Logs. If you do not want to test the connection at this point, select No, Skip This Test then Next. This also skips downloading product updates and release notes. Installation with YaST 21
