Linux Client Setup

Many Linux distributions with a Graphical User Interface (GUI) have built-in support for VPNs which can be configured through their default graphical network management utilities. In some cases, you may need to install "network-manager-openvpn" or "NetworkManager-openvpn", which can be found through your distributions GUI package management system.
