In this hands-on project, you finalize your Linux installation by configuring your network interface and disabling your firewall and SELinux configuration. (You will learn more about configuring Firewalls and SELinux in Chapter 15.) Finally, you will properly shut down your Linux system.

1. Log in to the GNOME desktop as sample user one.

2. Open the System menu and navigate to Administration, Network and supply the root user password of secret when prompted. Next, use the Network utility to configure the network interface on your system to obtain Internet access. The configuration parameters to gain Internet access on your campus network will be provided by your instructor. Close the Network Configuration utility when finished.

3. Open the System menu again and navigate to Administration, Firewall. Supply the root user password of secret if prompted. Click Disable, click Apply, and then click Yes to disable your firewall. Close the Firewall Configuration utility when finished.

4. Open the System menu again and navigate to Administration, SELinux Management. Supply the root user password of secret if prompted. Change the System Default Enforcing Mode to Disabled and close the SELinux Administration utility.

5. Press Ctrl+Alt+F2 to switch to a command-line terminal (tty2), and then log in to the terminal using the user name root and the password secret.

6. At the command prompt, type shutdown –h now to halt your system immediately. Which commands from Table 2-10 perform the same function as shutdown –h now?
