5.4.12. Network & Hostname

The Network & Hostname screen is used to configure network interfaces. Options selected here will be available both during the installation (if needed for tasks such as downloading packages from a remote location) and on the installed system.

Note

Network configuration is an expansive topic and many of the options available during the installation are beyond the scope of this document. For detailed information about networking, including both theoretical topics and specific instructions and examples, see the Fedora Networking Guide, available at http://docs.fedoraproject.org/.
Network & Hostname
The Network & Hostname screen. In the left pane, one physical interface and one custom VLAN interface is shown; the right side shows details of the currently selected interface. System hostname is configured at the bottom.
Figure 5.23. Network & Hostname

Locally accessible interfaces are automatically detected by the installation program and cannot be manually added or deleted. All detected interfaces are listed on the left side of the screen. Click an interface in the list to display its current configuration (such as IP and DNS address); the details are displayed on the right side of the screen.
Below the list of interfaces are two buttons. Use the + button to add a virtual network interface (Team, Bond or VLAN) as described in Section 5.4.12.1, “Adding a Virtual Network Interface”. To remove a previously created virtual interface, select it in the list and click the - button.
To change settings such as IP addresses, DNS servers, or routing configuration for an existing interface (both virtual and physical), select the interface in the left pane and click Configure in the bottom right corner of the screen. Available settings are described in Section 5.4.12.2, “Editing Network Interface Configuration”.
Use the ON/OFF switch in the top right corner to enable or disable the currently selected interface.
Below the list of connections, enter a host name for this computer in the Hostname input field. The host name can be either a fully-qualified domain name (FQDN) in the format hostname.domainname, or a short host name with no domain name. Many networks have a Dynamic Host Configuration Protocol (DHCP) service that automatically supplies connected systems with a domain name; to allow the DHCP service to assign the domain name to this machine, only specify the short host name.

5.4.12.1. Adding a Virtual Network Interface

To add a virtual network interface, click the + button at the bottom of the interface list. A new window will open, prompting you to select one of the three available types of virtual interfaces:
  • Bond - NIC (Network Interface Controller) Bonding, a method to bind multiple physical network interfaces together into a single bonded channel.
  • Team - NIC Teaming, a new implementation to aggregate links, designed to provide a small kernel driver to implement the fast handling of packet flows, and various applications to do everything else in user space.
  • Vlan (Virtual LAN) - A method to create multiple distinct broadcast domains which are mutually isolated.
Select the interface type you want to add, and click Add. Another dialog window will open, allowing you to edit any available settings for your chosen interface type. For information about available settings, see the respective sections of the Fedora Networking Guide, available at http://docs.fedoraproject.org/. Basic documentation is also available in Section 5.4.12.2, “Editing Network Interface Configuration”.

Note

To access the settings dialog again after you closed it, select the same interface in the list of configured interfaces and click Configure in the bottom right corner of the screen. To remove a virtual interface, select it in the list and click the - button below.
