Changes

After the system has started for the first time, the CentOS Setup Agent will appear with a welcome message. Click on the Forward button to display the Firewall settings. By default all ports are closed on the firewall with the exception of the ssh port which allows you to remotely log into the system. The topic of firewall configuration will be covered in more detail in the chapter entitled Basic CentOS Firewall Configuration so for now leave the default settings unchanged. Leave SELinux configured as Enforcing to ensure the most secure environment. Next, create a user account for yourself and verify the date and time. If you would like the date and time of your CentOS system to be synchronized which an external Network Time Protocol server, select the Synchronize date and time over network option before proceeding to the Sound Card screen. Having worked through all the set up pages, click Finish to exit the setup agent and log in using your newly created account credentials.
