Study Notes
Persistent Network Configuration
- In a TCP/IP network, each node must configure its network adapter to match the network requirements to enable communication.
- The system administrator must provide the basic configuration so the operating system can set up the appropriate network interface and identify itself and the network features at boot time.
NetworkManager
- Most Linux distributions use NetworkManager as a service daemon to configure and control the system's network connections.
- NetworkManager's purpose is to make network configuration simple and automatic.
- It arranges route changes, IP address fetching, and updates to the local list of DNS servers when using DHCP.
- It prioritizes wired connections over wireless connections by default.
- It tries to keep at least one connection active at all times, whenever possible.
Network Configuration Files
/etc/hostnameand/etc/hostsare used for basic TCP/IP host configuration./etc/nsswitch.confand/etc/resolv.confare also used for network configuration./etc/systemd/networkfiles are used to override network settings.- Files ending in
.netdevare used by systemd-networkd to create virtual network devices. - Files ending in
.linkset low-level configurations for network interfaces. - Files ending in
.networkset up network addresses and routes.
systemd-networkd
- systemd-networkd detects and configures network devices automatically as they appear.
- It ignores devices already configured by other means.
- There is little need to add configuration files in most situations.
- Configuration files can be used to select specific network interfaces using the
[Match]section. - Matching rules can be based on network interface names, MAC addresses, or shell-style globs.
