NOTES

Amazon Linux 2014.09 does not work with this script currently! Centos 6 and Ubuntu 12.04 and 14.04 LTS releases work, possibly many others too. Centos 7 is untested by the author.

Installation Instructions

OpenVZ script is for VPSes that use venet0 instead of eth0, normal script uses eth0.

RHEL, CentOS, Fedora

• Install unzip:

sudo yum -y install unzip

• Enable the EPEL repository. When writing this, it's as simple as:

sudo rpm -iv http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

If the link does not work, see instructions at http://fedoraproject.org/wiki/EPEL . Also EPEL may already be enabled on your server, so just try to run the setup script. The script will complain if it cannot install the openvpn package.

• Continue with the common instructions

Debian, Ubuntu, and other Debian based distros

• Install unzip:

sudo apt-get -y install unzip

• Continue with the common instructions

Common

• Make sure you sync your server's clock with NTP or you will be unable to connect to your new VPN server due to your SSL certificates being invalid

• Download the repo zip file and run the installation script:

wget https://github.com/viljoviitanen/setup-simple-openvpn/archive/master.zip
unzip master.zip
cd setup-simple-openvpn-master
sudo sh normal-setup.sh # or openvz-setup.sh

• By default, the script uses UDP 1194, but if you want to use a different port run the script with:

sudo sh <type>-setup.sh <port #> <protocol>

where port # can be anything between 1-65535, and protocol is either "tcp" or "udp" (no quotes).

• Let the script run. Take note if the server external IP address detection is succesful. If it's not, you need to edit the configuration files before using them.

• Download the configuration files from directory setup-simple-openvpn-master/openvpn.*, there is both a zipped file with all the config files and the plain configuration files

Client Installation

In a nutshell: Install an openvpn client, download the client configuration files from server somehow (e.g. with scp), then just use the configuration files. See Client Installation Guide for detailed instructions for Ubuntu, MacOS and Windows 7 desktops.

To-Do

• Add support for other Linux distros

• Possibly add OS X support

Modifications by Issac Kim

• Modified for use with OpenVZ VPSes, since they use venet0 instead of eth0.

• Added two versions of the script, one for protocol venet0 specific (openvz-setup.sh), and eth0 (normal-setup.sh).

• The script now creates a Linux specific version, since not all distros support the Windows method of pushing DNS configs, and also needs script-security 2.

• The config files are labeled with the public IP address, and the Linux specific config is labeled with "linux" at the beginning.
