How to Install Microproxy on OpenBSD

Microproxy is a lightweight proxy server that can intercept and modify HTTP and HTTPS traffic. In this tutorial, we will guide you through the process of installing Microproxy on OpenBSD.

Prerequisites

Before you start, ensure that you have the following:

• An OpenBSD server
• The latest version of the Microproxy source code from the Microproxy GitHub repository.

Step 1: Installing Dependencies

Microproxy uses OpenSSL and Zlib libraries. Before installing Microproxy, you need to ensure that these libraries are installed on your OpenBSD server.

To install these dependencies, open a terminal on your OpenBSD server and run the following command:

$ sudo pkg_add openssl
$ sudo pkg_add zlib

Step 2: Compiling Microproxy

After installing the dependencies, you need to compile the Microproxy source code.

1. Download the latest Microproxy source code to your OpenBSD server using the following command:

   $ git clone https://github.com/thekvs/microproxy.git
   

2. Navigate to the Microproxy directory using the following command:

   $ cd microproxy
   

3. Compile the Microproxy source code using the following command:

   $ make
   

Step 3: Installing Microproxy

After compiling Microproxy, you need to install it on your OpenBSD server.

1. Install Microproxy using the following command:

   $ sudo make install
   

2. Verify that Microproxy is installed by running the following command:

   $ microproxy --version
   

   If Microproxy is installed correctly, you should see the version number displayed on the terminal.

Step 4: Configuring Microproxy

After installing Microproxy, you need to configure it to intercept and modify HTTP and HTTPS traffic. This involves creating a configuration file that specifies the settings for Microproxy.

1. Navigate to the Microproxy configuration directory using the following command:

   $ cd /usr/local/etc/microproxy
   

2. Copy the sample configuration file to a new file using the following command:

   $ cp config.toml.example config.toml
   

3. Edit the configuration file using a text editor like vi or nano:

   $ sudo vi config.toml
   

4. Modify the configuration file to specify the settings for Microproxy. The configuration file is well documented and contains detailed instructions for configuring Microproxy.

5. Save and close the file.

Step 5: Running Microproxy

After configuring Microproxy, you need to start the Microproxy server.

1. Start the Microproxy server using the following command:

   $ sudo microproxy --config /usr/local/etc/microproxy/config.toml
   

2. Verify that Microproxy is running by navigating to a website using your web browser. If Microproxy is configured correctly, you should be able to see the intercepted traffic in the Microproxy logs.

Congratulations! You have successfully installed Microproxy on OpenBSD and configured it to intercept and modify HTTP and HTTPS traffic.
