Code Comparison

openvpn-install (Nyr):

openvpn-install (angristan):

#!/bin/bash

# https://github.com/angristan/openvpn-install
#
# This script is based on the great work of Nyr and its contributors.

The main difference in the code snippets is the attribution and licensing information. Angristan's version acknowledges that it's based on Nyr's work, while Nyr's version includes a copyright notice and MIT License reference.

Both scripts are well-maintained and offer easy OpenVPN server setup. Angristan's fork provides more advanced features and frequent updates, making it suitable for users who need additional customization options. Nyr's original script remains a solid choice for those seeking a simpler, straightforward installation process.

Pros of docker-openvpn

• Containerized solution, offering better isolation and easier deployment
• Supports easy scaling and management in container orchestration environments
• Provides a more consistent environment across different host systems

Cons of docker-openvpn

• Requires Docker knowledge and infrastructure
• May have a slightly higher resource overhead due to containerization
• Less straightforward for users unfamiliar with Docker concepts

Code Comparison

openvpn-install:

#!/bin/bash
# OpenVPN installer for Debian, Ubuntu, and CentOS

# Rest of the script...

docker-openvpn:

FROM alpine:3.14

LABEL maintainer="Kyle Manna <kyle@kylemanna.com>"

# Install openvpn
RUN echo "http://dl-cdn.alpinelinux.org/alpine/edge/community/" >> /etc/apk/repositories && \
    apk add --update openvpn iptables bash easy-rsa && \
    rm -rf /tmp/* /var/tmp/* /var/cache/apk/* /var/cache/distfiles/*

# Needed by scripts
ENV OPENVPN /etc/openvpn
ENV EASYRSA /usr/share/easy-rsa
ENV EASYRSA_PKI $OPENVPN/pki
ENV EASYRSA_VARS_FILE $OPENVPN/vars

The openvpn-install script is a bash script designed for direct installation on the host system, while docker-openvpn uses a Dockerfile to create a containerized OpenVPN environment.

Pros of setup-ipsec-vpn

• Supports multiple VPN protocols (IPsec/L2TP, IPsec/XAuth, and Cisco IPsec)
• Built-in support for both IPv4 and IPv6
• Includes options for split tunneling and DDNS configuration

Cons of setup-ipsec-vpn

• May require more complex client-side configuration
• Less widespread client support compared to OpenVPN
• Potentially more challenging to troubleshoot due to multiple protocols

Code Comparison

setup-ipsec-vpn:

wget https://git.io/vpnsetup -O vpnsetup.sh
sudo sh vpnsetup.sh

openvpn-install:

wget https://git.io/vpn -O openvpn-install.sh
sudo bash openvpn-install.sh

Both scripts offer straightforward installation processes, but setup-ipsec-vpn provides a more comprehensive VPN solution with multiple protocols, while openvpn-install focuses solely on OpenVPN, which may be simpler for some users to set up and manage.

setup-ipsec-vpn offers greater flexibility and protocol options, making it suitable for a wider range of devices and network configurations. However, openvpn-install's focus on a single protocol may result in easier troubleshooting and a more streamlined user experience for those who only need OpenVPN functionality.

Pros of algo

• Supports multiple VPN protocols (WireGuard, IPsec/IKEv2) for better flexibility and performance
• Emphasizes security with stronger encryption defaults and regular security audits
• Easier to set up and manage multiple users with a user-friendly CLI

Cons of algo

• Less customizable than openvpn-install, with fewer configuration options
• May have compatibility issues with older devices that don't support newer VPN protocols
• Requires more system resources due to its comprehensive security features

Code comparison

algo:

def deploy(server, config, update, client_name, client_os):
    ansible_command = [
        "ansible-playbook",
        "main.yml",
        "-e", "@config.cfg",
        "--limit", server
    ]

openvpn-install:

newclient () {
    # Generates the custom client.ovpn
    cp /etc/openvpn/client-common.txt ~/$1.ovpn
    echo "<ca>" >> ~/$1.ovpn
    cat /etc/openvpn/easy-rsa/pki/ca.crt >> ~/$1.ovpn
    echo "</ca>" >> ~/$1.ovpn
}

The algo project uses Python and Ansible for deployment, while openvpn-install relies on bash scripting for configuration and client management. algo's approach offers more structure and maintainability, while openvpn-install provides a simpler, more lightweight solution.

Pros of Streisand

• Supports multiple VPN protocols and services (OpenVPN, WireGuard, Shadowsocks, etc.)
• Provides additional security features like DNS leak prevention and firewall configuration
• Automates the setup of a complete privacy-focused server with various services

Cons of Streisand

• More complex setup process due to its comprehensive nature
• Requires more server resources to run multiple services
• May be overwhelming for users who only need a simple OpenVPN setup

Code Comparison

openvpn-install:

#!/bin/bash
# Simplified OpenVPN server installation
apt-get update
apt-get install openvpn easy-rsa -y

Streisand:

- name: Install OpenVPN
  apt:
    name: openvpn
    state: present

- name: Configure OpenVPN
  template:
    src: openvpn-server.conf.j2
    dest: /etc/openvpn/server.conf

Streisand uses Ansible for automation, while openvpn-install relies on a bash script. Streisand's approach allows for more complex configurations and better maintainability, but openvpn-install's script is simpler and more straightforward for basic OpenVPN setups.

Pros of PiVPN

• Supports both OpenVPN and WireGuard protocols
• User-friendly interface with guided setup process
• Actively maintained with regular updates and community support

Cons of PiVPN

• Limited to Raspberry Pi and Debian-based systems
• May require more system resources due to additional features
• Less customizable than a bare-bones script

Code Comparison

openvpn-install:

#!/bin/bash
# OpenVPN installer for Debian, Ubuntu, and CentOS

# Detect Debian users running the script with "sh" instead of bash
if readlink /proc/$$/exe | grep -q "dash"; then
    echo 'This installer needs to be run with "bash", not "sh".'
    exit
fi

PiVPN:

#!/usr/bin/env bash
# PiVPN: Simplest OpenVPN/WireGuard setup and management

# Must be root to install
if [[ $EUID -ne 0 ]]; then
    echo "This installer needs to be run with root privileges."
    exit 1
fi

Both scripts start with a shebang and perform initial checks. openvpn-install focuses on detecting the correct shell, while PiVPN checks for root privileges. PiVPN's code is more concise and modern, using [[ for conditionals and /usr/bin/env bash for improved portability.
