##openvpn-install OpenVPN road warrior installer for Debian, Ubuntu and CentOS.

This script will let you setup your own secure VPN server in no more than a minute.

##Fork

This script is based on the great work of Nyr and its contributors, big thanks to them.

I made it because I wanted to have a more secured OpenVPN out-of-the-box. It works like the original script, but is more focused on privacy and espicially better encryption. Nyr's original script uses mainly default parameters regarding encryption, but you can do a lot better with the latest versions of OpenVPN and have nearly state-of-the-art encryption.

The only drawback is that you need to use a recent version of OpenVPN. Therefore I restrain the compatibility of this script to a few but widely used GNU/Linux distributions, to get a recent version of OpenVPN from trusted third-party repositories.

I you want to use an OpenVPN server installed with this script with an old client (>2.3), it won't be compatible. If you can't upgrade your client, use Nyr's script.

Features

This fork includes the following features :

Variants

When you lauch the script you will be asked to choose a mode. Both will work the same way, but slow has higher encryption settings, so it may slow down your connection and take more time to install.

If you're just using your VPN at home, you may choose "fast". But if you're often using public Wi-Fi or traveling a lot, you choose use slow.

FYI, "fast" is still more secured than default OpenVPN settings.

Slow (high encryption)

Features :

  • 4096 bits RSA private key
  • 4096 bits Diffie-Hellman key
  • 256 bits AES-GCM

Fast (lower encryption)

Features :

  • 2048 bits RSA private key
  • 2048 bits Diffie-Hellman key

##Installation

You have to enable the TUN module otherwise OpenVPN won't work. Ask your host if you don't know how to do it. If the TUN module is not enabled, the script will tell you.

Run the script and follow the assistant:

wget https://raw.githubusercontent.com/Angristan/OpenVPN-install/master/openvpn-install.sh
chmod +x openvpn-install.sh
./openvpn-install.sh

Once it ends, you can run it again to add more users, remove some of them or even completely uninstall OpenVPN.

You can get a cheap VPS for 3€/month at PulseHeberg.
