Chapter 3. Configuring IP Networking
As a system administrator, you can configure a network interface either using NetworkManager or not.
3.1. Selecting Network Configuration Methods
- To configure a network interface using NetworkManager, use one of the following tools:
- the text user interface tool, nmtui. For more details, see Section 3.2, “Configuring IP Networking with nmtui”.
- the command-line tool, nmcli. For more details, see Section 3.3, “Configuring IP Networking with nmcli”.
- the graphical user interface tools, GNOME GUI. For more details, see Section 3.4, “ Configuring IP Networking with GNOME GUI ”.
- To configure a network interface without using NetworkManager:
- edit the
ifcfgfiles manually. For more details, see Section 3.5, “Configuring Ip Networking with ifcfg Files”. - use the
ipcommands. This can be used to assign IP addresses to an interface, but changes are not persistent across reboots; when you reboot, you will lose any changes. For more details, see Section 3.6, “Configuring IP Networking with ip Commands”.
- To configure the network settings when the root filesystem is not local:
- use the kernel command-line. For more details, see Section 3.7, “Configuring IP Networking from the Kernel Command line”.
