How to install Patrowl on OpenBSD

Patrowl is an open-source security tool that helps white hat hackers and security experts to identify vulnerabilities in web applications, networks, and systems. In this tutorial, we will show you how to install and configure Patrowl on OpenBSD.

Prerequisites

• OpenBSD system
• Sudo or root user access
• Internet connection

Step 1: Update your system

Update your OpenBSD system to ensure that you have the latest security patches and software updates. You can update your system by running the following command:

$ sudo pkg_add -u

Step 2: Install the necessary dependencies

Patrowl requires several packages to be installed before it can be installed. We will install them with the OpenBSD package manager.

$ sudo pkg_add python3 py3-pip py3-virtualenv git postgresql-server postgresql-client

Step 3: Create a new PostgreSQL database

Patrowl requires a database to store its data. We will create a new PostgreSQL database for Patrowl by running the following command:

$ su - _postgresql
$ initdb -D /var/postgresql/data

# Start the database and enable it on boot
$ rcctl start postgresql
$ rcctl enable postgresql

Step 4: Clone the Patrowl repository

We will now clone the Patrowl repository and set up a virtual environment for it.

$ git clone https://github.com/Patrowl/PatrowlManager.git
$ cd PatrowlManager
$ python3 -m venv venv
$ source venv/bin/activate

Step 5: Install Patrowl and its dependencies

Install the Patrowl and its dependencies by running the following command:

(venv) $ pip install -r requirements.txt

Step 6: Configure Patrowl

Configure the Patrowl application by creating a configuration file. You can use the sample configuration file as a template:

(venv) $ cp patrowl/config.py.sample patrowl/config.py

Edit the configuration file to add your PostgreSQL database details:

SQLALCHEMY_DATABASE_URI = 'postgresql://user:password@localhost:5432/userdb'

Step 7: Initialize the Patrowl database

We will now initialize the Patrowl database and create the tables:

(venv) $ python manage.py db init
(venv) $ python manage.py db migrate
(venv) $ python manage.py db upgrade

Step 8: Start Patrowl

We can now start the Patrowl application:

(venv) $ python run.py

Conclusion

In this tutorial, we have shown you how to install Patrowl on OpenBSD. Patrowl is a powerful security tool that can help you identify and mitigate vulnerabilities in your systems.
