I just set up Openvpn version 2.3.2 from the EPEL repo on CentOS 6.5 64bit and I cannot seem to connect to it from my Manjaro (arch linux based) client. I followed this guide for the server and client and have double checked to make sure I did everything right (
http://www.unixmen.com/setup-openvpn-server-client-centos-6-5/). I tried doing a test on the client (client and host are on the same router/subnet) machine by running the command "openvpn /etc/openvpn/client.conf" and I got back this
