Install OpenVPN server and Easy-RSA

Question

I have Ubuntu Server 14.04 and I am trying to install OpenVPN and Easy-RSA. However, this machine can not access anything outside its network. So I can't use apt-get to install it.

I downloaded OpenVPN tar file (on my local computer and used scp to transfer it over) and I believe I installed it correctly by running these commands:

./configure 
make
sudo make install

When I do openvpn --version, I get this:

OpenVPN 2.3.8 x86_64-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [MH] [IPv6] built on Oct 12 2015
library versions: OpenSSL 1.0.1f 6 Jan 2014, LZO 2.06

So I think that's fine. I downloaded and transferred easy-rsa from here: https://github.com/OpenVPN/easy-rsa, but I don't know how to install it.

What do I need to do? Any help would be appreciated!

Solution

Download the latest zip file from the "releases" list on GitHub. Right now it's version 3.0.0. The easyrsa file is the script you want.

$ wget -q https://github.com/OpenVPN/easy-rsa/releases/download/3.0.0/EasyRSA-3.0.0.tgz
$ tar -xzf EasyRSA-3.0.0.tgz
$ ls
EasyRSA-3.0.0/  EasyRSA-3.0.0.tgz
$ cd EasyRSA-3.0.0/
$ ls easyrsa
easyrsa*

You can also make a link to it if you need to:

$ ln -s $(pwd)/easyrsa /usr/bin/easyrsa
$ easyrsa

You should be able to simply run easyrsa/easyrsa. It's a shell script and looks like it doesn't need building.

Am I downloading the right tar.gz/zip file? I don't have a easyrsa/easyrsa. Which release did you download?

[MasterOfBinary]

I see that now. I was just looking at contents of the git repository.

Is /easyrsa supposed to be /easyrsa3? I'm guessing it is since I have the executable easyrsa in that folder.

The file you want is that executable easyrsa and the commands I provided create a link to it in /usr/bin/ (assuming you're already in the EasyRSA-3.0.0/ directory.
