OpenVPN Update resolvconf
Description
This is a script to update your /etc/resolv.conf with DNS settings that come from the received push dhcp-options. Since network management is out of OpenVPN client scope, this script adds and removes the provided from those settings.
This script was found on the OpenVPN page of the Archlinux Wiki
However if you have systemd 229 or newer the better option is to use script from https://github.com/jonathanio/update-systemd-resolved which uses DBus calls instead of creating temporary *.network files.
Usage
Install openresolv
Place the script in /etc/openvpn/update-resolv-conf.sh or anywhere the
OpenVPN client can acess.
Add the following lines to your client configuration:
# This updates the resolvconf with dns settings
setenv PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
script-security 2
up /etc/openvpn/update-resolv-conf.sh
down /etc/openvpn/update-resolv-conf.sh
down-pre
Just start your openvpn client with the command you used to do.
Alternatively, if you don't want to edit your client configuration, you can add the following options to your openvpn command:
--setenv PATH '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin' --script-security 2 --up /etc/openvpn/update-resolv-conf.sh --down /etc/openvpn/update-resolv-conf.sh --down-pre
