VPN-Hole

A self-contained GoLang library that is capable of blocking ads,malwares and trackers using DNS Sinkholing. This libray can be integrated with different pre-existing cross-platform applications.

You can learn more about the project from the blogs at leap.se.

Installation

Go

The detailed download and installation guide can be found at official website of Go.

For Linux:

# 1. Download Go Binary Archive
wget https://golang.org/dl/go1.18.4.linux-amd64.tar.gz

# 2. Extract it
tar -xzf go1.18.4.linux-amd64.tar.gz -C /usr/local/

# 3. Add PATH Variables
sudo nano /etc/profile
export PATH=$PATH:/usr/local/go/bin
source /etc/profile

# 4. Check Go Version
go version

You can refer to the official documentation for setting GOPATH.

GoMobile & Gobind

After installing Go, we need gobind. Gobind is a tool that generates language bindings that make it possible to call Go functions from Java and Objective-C. It is called internally by gomobile which can help us build cross-platform applications.

go install golang.org/x/mobile/cmd/gomobile@latest

# To compile Android APK and IOS Apps
gomobile bind [-target android|ios|iossimulator|macos|maccatalyst] [-bootclasspath <path>] [-classpath <path>] [-o output] [build flags] [package]

VPN-Hole

To clone and build VPN-Hole Library:

git clone https://0xacab.org/leap/vpn-hole.git

cd vpn-hole

Instructions

To load all of the packages in the main module:

# If go.mod and go.sum are present then,
# Run 
go mod tidy

If go.mod and go.sum are missing from the cloned repository, then:

go mod init [module-path]

Build & Run

# build the library
go build

An executable binary file would be generated for the library.

# executing the binary

Integration

To integrate the VPN-Hole Library with existing cross-platform applications, we will be using gomobile to compile and bind it.
