Mullvad

Using Mullvad as plain OpenVPN

To use the VPN service Mullvad on Arch Linux a few small adjustments need to be done. First, install OpenVPN and resolvconf. Download the plain OpenVPN version of Mullvad "here". Next, copy the content of the zip file to /etc/openvpn. Open the file mullvad_linux.conf and change the end of the file from

mullvad_linux.conf

# Parses DHCP options from openvpn to update resolv.conf
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

ping 10

ca master.mullvad.net.crt
cert mullvad.crt
key mullvad.key

to

mullvad_linux.conf

# Parses DHCP options from openvpn to update resolv.conf
# up /etc/openvpn/update-resolv-conf
# down /etc/openvpn/update-resolv-conf
up /usr/share/openvpn/update-resolv-conf
down /usr/share/openvpn/update-resolv-conf

ping 10

ca /etc/openvpn/master.mullvad.net.crt
cert /etc/openvpn/mullvad.crt
key /etc/openvpn/mullvad.key

and make it executable by running

   sudo chmod +x /etc/openvpn/mullvad_linux.conf

Load the tun module by creating the file

/etc/modules-load.d/tun.conf

# Load tun.ko at boot
tun

and create

/usr/share/openvpn/update-resolv-conf

#!/bin/bash
#
# Parses DHCP options from openvpn to update resolv.conf
# To use set as 'up' and 'down' script in your openvpn *.conf:
# up /etc/openvpn/update-resolv-conf
# down /etc/openvpn/update-resolv-conf
#

# Example envs set from openvpn:

# foreign_option_3='dhcp-option DOMAIN be.bnc.ch'

[ -x /usr/sbin/resolvconf ] || exit 0

case $script_type in

up)
   for optionname in ${!foreign_option_*} ; do
      option="${!optionname}"
      echo $option
      part1=$(echo "$option" | cut -d " " -f 1)
      if [ "$part1" == "dhcp-option" ] ; then
         part2=$(echo "$option" | cut -d " " -f 2)
         part3=$(echo "$option" | cut -d " " -f 3)
         if [ "$part2" == "DNS" ] ; then
            IF_DNS_NAMESERVERS="$IF_DNS_NAMESERVERS $part3"
         fi
         if [ "$part2" == "DOMAIN" ] ; then
            IF_DNS_SEARCH="$part3"
         fi
      fi
   done
   R=""
   if [ "$IF_DNS_SEARCH" ] ; then
           R="${R}search $IF_DNS_SEARCH
"
   fi
   for NS in $IF_DNS_NAMESERVERS ; do
           R="${R}nameserver $NS
"
   done
   echo -n "$R" | /usr/sbin/resolvconf -a "${dev}.inet"
   ;;
down)
   /usr/sbin/resolvconf -d "${dev}.inet"
   ;;
esac

and don't forget to make it executable by running

   sudo chmod +x /usr/share/openvpn/update-resolv-conf

Lastly create the file

/usr/bin/mullvad

#! /bin/bash
# Script to start Mullvad
gksu openvpn /etc/openvpn/mullvad_linux.conf

make it executable

   sudo chmod +x /usr/bin/mullvad

and simply run Mullvad in the terminal by typing

   mullvad

To create a menu item we need the logo

   wget https://mullvad.net/images/logo.png -O /usr/share/icons/mullvad.png

Then create the .desktop file

/usr/share/applications/mullvad.desktop
