310 Part III . Choosing and Installing a Linux Distribution Because the Debian CD image included with this book is the network install image, the CD itself will provide software for installing only a minimal Debian system. You will need a network connection or other Debian software CDs to install, for example, a full desktop system or the LAMP and mail servers described in Chapter 24 and 25. 8. You have the option of adding another APT source. If you have an Internet connection and want to have the installer check for updated packages, choose either the HTTP or FTP methods (HTTP is recommended), and then select a country and a mirror server from the list. You are prompted for any HTTP proxy configuration, which may be necessary on some corporate or school networks. If you aren t sure, check with your support desk. If it does not apply, just leave it empty. APT retrieves a list of packages from the site that you selected. 9. The installer attempts to retrieve a list of security updates from the Debian security archive. This step will fail if you do not have an Internet connection, but you can still finish the rest of the installation. 10. You are presented with a list of predefined package sets (known as tasks) that you can select for installation. Package installation is covered in greater detail later, so I recommend that you do not select any tasks from this list now. Use the tab key to get to the OK button. 11. APT downloads any updated packages (this could take quite a while, depending on available updates and your connection speed), and debconf prompts you to configure any packages that are in the half-installed state. If at any time you are uncertain about which option to select, you can probably stick with the default. 12. Assuming that you did not select any tasks, the only package needing configuration is the Exim mail transfer agent. The configuration questions that are asked during this stage may vary. When in doubt, use the default settings. When the Configuring Exim screen appears, you choose from a list of default configurations; here are the most likely options: internet site; mail is sent and received directly using SMTP This option configures your server to accept incoming mail and to deliver outgoing mail directly to the servers for the recipient domain. This configuration is useful if you are running a simple mail server or if you are using mutt or pine to check your mail locally. mail sent by smarthost; received via SMTP or fetchmail This option is almost identical to the previous option, except you will be prompted to enter a server that all outgoing mail will be sent through. This option may be necessary if the ability to connect directly to outside mail servers is prohibited on your network. local delivery only; not on a network Select this option if you do not need locally generated messages to be sent to a central mail host for processing. Your system will not be configured with the capability to Note
