Installing an OpenVPN client:

Usually, the easiest way to install an OpenVPN client is to use the package management system for your particular Linux distribution. Run one of the following commands (as root):

Fedora/CentOS/RedHat:

yum install openvpn

NOTE: OpenVPN Access Server is not compatible with any version below the 2.1 OpenVPN Community/Linux client!

Ubuntu/Debian:

apt-get install openvpn

Once the openvpn package is fetched from the Internet and installed, run the client with the --version argument to make sure that it is version 2.1:

openvpn --version
OpenVPN 2.1_rc15e x86_64-unknown-linux-gnu [...]
[...]

Running the OpenVPN client with the downloaded client config file: Usually, the easiest way to install an OpenVPN client is to use the --config argument to specify the location of the downloaded client config file:

openvpn --config client.ovpn
