How to Install SOCKS5Engine on OpenBSD

This tutorial will guide you on how to install SOCKS5Engine on OpenBSD. SOCKS5Engine is an implementation of the SOCKS v5 protocol for secure communication.

Requirements

OpenBSD
Git
CMake

Installation

Start by updating your package repository by opening your terminal window and typing:
```
$ sudo pkg_add -u
```
Install Git by typing:
```
$ sudo pkg_add git
```
Clone the SOCKS5Engine source code from the official repository on Github by typing:
```
$ git clone https://github.com/VeeSecurity/SOCKS5Engine.git
```
Navigate to the directory where you cloned the SOCKS5Engine source code by typing:
```
$ cd SOCKS5Engine
```
Run the CMake command to create the makefile for building the source code by typing:
```
$ cmake .
```
Once the makefile has been successfully created, run the make command to build the SOCKS5Engine code by typing:
```
$ make
```
Run the install command to install the binaries to the system by typing:
```
$ sudo make install
```
Verify that the SOCKS5Engine has been installed correctly by running the following command:
```
$ socks5engine --version
```

Configuring SOCKS5Engine

After installing the SOCKS5Engine, you can configure it by editing the configuration file located at /etc/socks5engine.conf. Here's an example configuration file:

{
   "debug": true,
   "listen": "127.0.0.1:1080",
   "user": "socksuser",
   "password": "supersecret",
   "rules":
   [
      {
          "destination": "0.0.0.0/0",
          "port": "0-65535",
          "action": "allow"
      }
   ]
}

In the example above, the SOCKS5Engine will listen on the loopback interface on port 1080. Authentication is enabled, and the username and password are set to "socksuser" and "supersecret" respectively. The "rules" section allows you to define access control rules for incoming connections. In the example, all traffic is allowed to all destinations and ports.

Conclusion

You have now successfully installed and configured SOCKS5Engine on OpenBSD. You can now use it to securely communicate over SOCKS v5 protocol.
