Wireguard¶

Le VPN Kiss, utilisant les dernières règles de l'art, construit pour être audité & performant ! au revoir IPSec & OpenVPN !

Installation¶

https://www.wireguard.com/install/

Dans le Kernel Linux : via DKMS pour l'instant (2019-08-15) et en userspace écrit en GO (en cours de migration en Rust) sur les autres plateformes (*BSD, OpenWRT, Android, Windows).

Pour Debian stable, au départ « Stretch » 9.8 et dorénavant « Buster » 10.0, des paquets wireguard{,-dkms,-modules} sont installables depuis le dépôt unstable (uniquement). Les mises à jour y sont fréquentes, par exemple les versions disponibles au 2019-03-07 étaient les 0.0.20190227-1, celles disponibles au 2019-07-19 étaient les 0.0.20190702-1.

ATTENTION : sous Debian Stretch, une bogue introduite dans la dernière mise à jour du paquet des entêtes du noyau (2019-09-14), casse la compilation du module Wireguard. Il reste possible de compiler le module avec la version précédente, puis de l'utiliser avec la dernière version du noyau.

Configuration¶

Serveur¶

umask 077
wg genkey > /etc/wireguard/private
wg genkey | tee /etc/wireguard/private | wg pubkey > /etc/wireguard/publickey
wg set wg0 private-key /etc/wireguard/private
ip link set wg0 up

cat << EOF > /etc/wireguard/wireguard.conf
[Interface]
ListenPort = 50000 
PrivateKey = `cat /etc/wireguard/private`

[Peer]
PublicKey = Va0X1zOpRc9471Aa3DEUUy7UkAv5aq5SojtIPqOSqwg=
AllowedIPs = 10.33.33.0/24
Endpoint = 185.233.100.19:50000
EOF

Client¶

umask 077
wg genkey | tee /etc/wireguard/private | wg pubkey > /etc/wireguard/publickey
wg set wg0 private-key /etc/wireguard/private
ip link add dev wg0 type wireguard
ip link set wg0 up

Config serveur (Hypnos)¶

#!/bin/bash

set -x -e

# Creating the wireguard interface
ip link add dev wg0 type wireguard

# Setting the IP on the wireguard interface
ip address add dev wg0 185.233.101.127/24

# Configuring the wireguard server
wg set wg0 listen-port 50000 private-key /etc/wireguard/private

# Starting up the wireguard interface
ip link set up dev wg0

# Add Client
wg set wg0 peer W/iRbRNZhftkcmkfS/pUNcyDJ1YHB0cBEDigzed6+B0= allowed-ips 185.233.101.126/32

# Create the static route for the client
ip route add 185.233.101.126/32 dev wg0 proto static

Config client¶

#!/bin/bash

set -e -x

# Creating the wireguard interface
ip link add dev wg0 type wireguard

# Setting the IP on the wireguard interface
ip address add dev wg0 185.233.101.126/24

# Configuring wireguard
wg set wg0 private-key ./private

# Starting up the wireguard interface
ip link set up dev wg0

# Connect to the server
wg set wg0 peer 'XRhI4WqBipwY21pxPZ9Q7EWkypnQCKKtJjqu2tUUTVo=' allowed-ips 0.0.0.0/0 endpoint 185.233.100.9:50000
