  • SSH Bastion Host Best Practices

    Overall, the core concept of security hardening a bastion host is to run a bastion server with minimal components and reduce the attack surface as much as possible. As you will find below, most of the controls required to secure bastion hosts are, in fact, the same as hardening an operating system. Below, we present a few important things to consider while designing a bastion host.

  • SSH and HTTP to a Raspberry Pi behind CG-NAT

    This modem is on AT&T's network, but regardless of the provider, unless you're willing to pay hundreds or thousands of dollars a month for a SIM with a public IP address, the Internet connection will be running behind CG-NAT.

    What this means is there's no publicly routable address for the Pi—you can't access it from the public Internet, since it's only visible inside the cell network's private network.

  • Kali http server setup

    There are multiple ways to set up an HTTP web server in Kali Linux. Apache, NGINX, and Python are a few of the ways this can be accomplished.

    Since you are looking to set up a web server on Kali, it might be safe to assume that you are trying to spoof some other website, or dupe users with some sort of phishing ploy. In that case, all three web server types have their pros and cons, with Python being the quickest one to get up and running.

    Whatever the purpose of your web server may be, nefarious or not, you will learn how to install and configure a simple HTTP server using either Apache, NGINX, or Python in this tutorial. Follow through our step by step instructions below to see how it’s done.

  • How to install Kibana Dashboard on Ubuntu 22.04 | 20.04 LTS - Linux Shout

    Analyze the data collected by the Elasticsearch search engine software visually by installing Kibana Dashboard on Ubuntu 22.04 Jammy Jellyfish or 20.04 Focal Fossa.

    Elasticsearch is a popular enterprise search engine software to collect data, index, and analyze it. The software is open-source, hence distributed to use free of cost. The key feature is it can examine and index a wide variety of data types that can be structured or unstructured. For example, it can be text-based data, numerical data, data with time information, or data with geographic information.

    But this Elastic Seach doesn’t offer itself a graphical option to analyze data, hence to get that we use Kibana, an open-source analysis, and visualization platform. Together with Elasticsearch and Logstash, it forms the Elastic Stack and enables the data collected by Elasticsearch to be visualized. Users can have various types of visualizations representation of their data such as line diagrams, pie charts, donut charts, or histograms. And allows the display of time series or geographical data. Kibana can be operated both on-premises and cloud-based.

  • Install CouchDB using Docker and Docker-compose

    CouchDB is an open-source NoSQL document database that stores data in JSON-based format and offers HTTP-ready REST-API out of the box.

    It can be used as a database backend for web, mobile, or even desktop apps. In contrast, it uses JSON for documents, an HTTP API, & JavaScript/declarative indexing.

    Although, CouchDB can be installed on Ubuntu or Linux using Snap, many developers may require to install it using Docker.

  • How to Install MySQL Workbench in RHEL Systems

    This article piece assumes that you already have the famed MySQL software installed on your RHEL-based Linux system and are ready to exploit database administration to the fullest.

    You log in to the MySQL shell and create the needed databases and their associated tables. You create the needed relationships between these database tables and start managing your data.

    However, this approach does not give you the needed dynamic control in managing your data. Also, it takes too much time switching between databases, creating users and data, viewing linked data, and executing other database-related queries.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
