Wireguard

Wireguard (https://www.wireguard.com/) on VPN tarkvara, mis väidab ennast olevat hulga kiirem ja lihtsam kahest suuremast konkurendist IPSecist ja OpenVPNist. Vaatame siis.

Artikli kirjutamise hetkel (2018-08) on tegu veel muidugi "beeta" tarkvaraga. Artikkel on kirjutatud Alpine Linuxi näitel.

Tegu on point-to-point tunneliga (tun seadmega).

Vajalik on wireguard kerneli moodul.

Probleemid

DKMS module not available

If the following command does not list any module after you installed wireguard-dkms,

modprobe wireguard && lsmod | grep wireguard

or if creating a new link returns

# ip link add dev wg0 type wireguard

RTNETLINK answers: Operation not supported

you probably miss the linux headers.

These headers are available in linux-headers or linux-lts-headers depending of the kernel installed on your system.
