The following portion of the Handbook describes 'simple' network configuration for systems running the OpenRC init system, utilizing netifrc as the network management system.

Readers using systemd should review see the networking portion of the systemd article.

Getting started with netifrc

Netifrc is a simple framework for configuring and managing network interfaces on OpenRC based systems. sys-apps/openrc pulls net-misc/netifrc automatically, as the netifrc USE flag is enabled by default.

Creating an interface init script

In order to manage an interface with netifrc, an init script for that interface must be created. By default, netifrc installs /etc/init.d/net.lo, which can be symlinked to create init scripts for new interfaces.

To create a new init script for interface eth0, simply symlink the default net.lo script:

root /etc/init.d #ln -s net.lo net.eth0

Tip
Interface names can be determined by running ip link show (ip l for short) or ls /sys/class/net.

Important
Interface names will differ from system to system. Kernel based device names starting with eth<n> or wlan<n> may differ by index across boots. udev may set interface names starting with wlp or enp, where these names are persistent across reboots.

Configuring netifrc interfaces

Ethernet interfaces will often work without any additional config, as netifrc will automatically use DHCP for interfaces with no specified config.

If additional configuration is needed, for options such as static IPs, /etc/conf.d/net can be edited:

FILE /etc/conf.d/netSetting a static IP for eth0.

# For static IP using CIDR notation
config_eth0="192.168.0.7/24"
routes_eth0="default via 192.168.0.1"
dns_servers_eth0="192.168.0.1 8.8.8.8"

# For static IP using netmask notation
config_eth0="192.168.0.7 netmask 255.255.255.0"
routes_eth0="default via 192.168.0.1"
dns_servers_eth0="192.168.0.1 8.8.8.8"

Note
If no configuration is specified for an interface, DHCP is used.

Netifrc interface service management

With the interface init scripts created and configured, netifrc services can be managed using rc-service. To start eth0:

root #rc-service net.eth0 start

Important
When troubleshooting networking, take a look at /var/log/rc.log. Unless the rc_logger variable is set to NO in /etc/rc.conf, information on the boot activity will be stored in that log file.

To start eth0 automatically at startup, it can be added to the default runlevel:

root #rc-update add net.eth0 default
