Network

Network configuration in Void Linux can be done in several ways. The default installation comes with the dhcpcd(8) service enabled.

Interface Names

Newer versions of udev(7) no longer use the traditional Linux naming scheme for interfaces (eth0, eth0, wlan0, ...).

This behavior can be reverted by adding net.ifnames=0 to the kernel cmdline.

Static Configuration

A simple way to configure a static network at boot is to add the necessary ip(8) commands to the /etc/rc.local file:

route add default via 192.168.1.1 ```

## dhcpcd

To run [dhcpcd(8)](https://man.voidlinux.org/dhcpcd.8) on all interfaces,
enable the `dhcpcd` service.

To run `dhcpcd` only on a specific interface, copy the `dhcpcd-eth0` service
and modify it to match your interface:

$ ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether ff:ff:ff:ff:ff:ff brd ff:ff:ff:f

cp -R /etc/sv/dhcpcd-eth0 /etc/sv/dhcpcd-enp3s0

sed -i 's/eth0/enp3s0/' /etc/sv/dhcpcd-enp3s0/run

ln -s /etc/sv/dhcpcd-enp3s0 /var/service/

For more information on configuring `dhcpcd`, refer to
[dhcpcd.conf(5)](https://man.voidlinux.org/dhcpcd.conf.5)

## Wireless

Before using wireless networking, use
[rfkill(8)](https://man.voidlinux.org/rfkill.8) to check whether the
relevant interfaces are soft- or hard-blocked.

Void provides several ways to connect to wireless networks:

- [wpa_supplicant](./wpa_supplicant.md)  - [iwd](./iwd.md)  -
[NetworkManager](./networkmanager.md)  - [ConnMan](./connman.md)
