Network

Wifi

Being able to connect to the internet is essential so lets set it up. Although dhcp will already work out of the box, wifi will not. Luckily there exist wpa_supplicant. First install the necessary packages:

# apk add networkmanager-wifi wpa_supplicant

Then configure /etc/NetworkManager/NetworkManager.conf to use wpa_supplicant:

[main] 
dhcp=internal
plugins=ifupdown,keyfile

[ifupdown]
managed=true

[device]
wifi.scan-rand-mac-address=yes
wifi.backend=wpa_supplicant

Now restart the service and you should be able to connect to the Wifi.

# rc-service networkmanager restart

There are different frontends to configure connections but for now lets install networkmanager-tui:

# apk add networkmanager-tui
# nmtui

It should be pretty self-explanatory on how to use it.

VPN's

NetworkManager can already use WireGuard but to use other VPN types it might be necessary to install their corresponding plugin. For OpenVPN that would be:

# apk add networkmanager-openvpn

Security

NetworkManager's defaults are fine for normal usage but in terms of security they are definitly lacking.

MAC Randomization

Create a config file /etc/NetworkManager/conf.d/mac-rand.conf to randomize te mac address for every time your computer connects:

[connection-mac-randomization]
ethernet.cloned-mac-address=random
wifi.cloned-mac-address=random

IPv6 privacy

Although ipv6 will be turned off in the security section you can still turn this on just in case byediting /etc/NetworkManager/conf.d/ip6-privacy.conf:

[connection]
ipv6.ip6-privacy=2
