NAME

network — bringing up the network in the rawnix installer

DESCRIPTION

The installer starts no network service by itself: not dhcpcd(8), not wpa_supplicant(8), not the time daemon. Each is started by hand. The services are installed, only not enabled, so sv up name works too.

The install needs a working connection to rsync.rawnix.org.

Finding the interface

# ip link

lists the network interfaces. Wired ones are typically called eth0 or enp..., wireless ones wlan0 or wlp....

Wired

# dhcpcd eth0

dhcpcd(8) gets an address, a route and name servers, and writes them to /etc/resolv.conf. Without an interface name it configures every interface it finds.

Wireless

Write the network's name and passphrase to a configuration file, start wpa_supplicant(8) on it, then get an address:

# wpa_passphrase "SSID" "passphrase" > /tmp/wpa.conf
# wpa_supplicant -B -i wlan0 -c /tmp/wpa.conf
# dhcpcd wlan0

The installer carries firmware only for a few USB wireless adapters (Ralink rt73 and rt2870, Realtek rtl8192c, rtl8192cu and rtl8192du). Other adapters that need firmware do not come up.

Static address

# ip link set eth0 up
# ip addr add 192.0.2.10/24 dev eth0
# ip route add default via 192.0.2.1

/etc/resolv.conf already names two public name servers, 1.1.1.1 and 9.9.9.9; edit it if they are not reachable from this network.

Checking

# ip addr
# ping -c 3 rawnix.org

FILES

/etc/resolv.conf: Name servers.
/tmp/wpa.conf: The wireless configuration from the example; it is lost at reboot.
