This tutorial describes configuration techniques of module the Apache SSL module, which extends the functionality of Apache web server to support SSL protocol. The tutorial will deal with authentication of server (One-way SSL authentication), as well as it will also include authentication of clients by using certificates (Two-way SSL authentication).

Where to get linux: How to get started beginner guide
The purpose of this tutorial is to serve as an introduction to the Linux operating system by showing prospective users where they can download Linux distributions, and help them choose which one would best fit their needs.
Collection of basic Linux Firewall iptables rules
The purpose of this guide is to show some of the most common iptables commands for Linux systems. iptables is the firewall built into all Linux distributions. Even distros like Ubuntu, which utilizes ufw (uncomplicated firewall), and Red Hat, which utilizes firewalld still pass their commands to iptables and use it in the background.
Mastering iptables, or at least becoming familiar with some of the most basic commands, is essential for Linux administrators. Even casual Linux users can benefit from understanding the basics of the iptables firewall, since they may be required to apply some minor configurations to it at some point. Use some of the examples below to familiarize yourself with the iptables syntax and get an idea for how it works to protect your system.
You should not apply iptables rules to a production system until you are somewhat familiar with how they work. Also be careful when applying rules to remote systems (a computer that you have established an SSH session with) because you can accidentally lock yourself out if you enter the wrong rule.
In this tutorial you will learn:

Get Started with Android application development using Linux and Android SDK
Developers interested in the Android mobile operating system are able to use the Android SDK and various IDE software to code applications. These apps can then be made available and marketed to Android users around the world.
There are a lot of choices when it comes to programming Android applications. Your coding environment can involve a Linux system and a variety of different IDE programs to facilitate all of the software development. The trouble here is that each Linux distribution will often have a different set of requirements to run the sofware, and a separate list of steps that need to be followed.
In this guide, we’ll go through the step by step instructions to install Android Studio – which is one of the most popular Android IDEs – on a Linux system. This will work on any distribution because we’ll be using Snap package manager to manage the installation. Love it or hate it, the Snap package manager gets your system ready for Android development very quickly, by handling all the dependencies and working identically on any distribution you’re running, whether it be Ubuntu, Debian, Red Hat, CentOS, AlmaLinux, openSUSE, or any other type of Linux system.
Follow along with us below as we setup Snap package manager, install Android Studio, and then program a Hello World Android application to verify that everything is working properly.
In this tutorial you will learn:
- How to setup Snap package manager
- How to install Android Studio and SDK packages
- How to create a Hello World test application
- How to run an Android application on an emulated device
Android system architecture
The purpose of this tutorial is to explore the system architecture of the Android mobile operating system. This will give you a general idea of the various layers involved in Android and how they relate to each other. We will also talk about how Android relates to Linux itself.
How to install package on Debian Linux
If you are new to Debian Linux, one of the first things you will be wondering how to do is install a software package. Although Debian usually comes with all the essential software installed out of the box, you will inevitably want to extend the operating system’s functionality even further, which can only be done through installing more software. Debian gives us a lot of options to do so, including through the system package manager, software center, or installing a .deb
file.
Linux Cheat Sheet
In this tutorial, we will list various practical Linux commands to be used only as a reference guide and by experienced Linux users. Not all Linux commands will be available on your system by default so consider installing the relevant package before use.
How to use rsync over ssh
rsync stands for “remote sync” and is a powerful command line utility for synchronizing directories either on a local system or with remote machines. It’s built into nearly every Linux system by default which allows users to perform rsync over ssh communication/backup.
Pax command examples on Linux
pax is an archive utility somewhere between cpio
and tar
. This is just because it is independent of the specific archive format, and supports a wide variety of different archive formats. It can perform simple tasks as creating a compressed archive of a selected directory or it can as much easily create a daily incremental backup.
Burn ISO to USB in Linux
The purpose of this tutorial is to show how to burn an ISO file to a USB drive. USB drives have recently overtaken CDs and DVDs as the primary media of physically distributed software. It is now a common task for system administrators and normal users to install operating systems and software via USB.
How to Setup OpenVPN Server
Running an VPN server on your local area network will allow outside clients to connect to your server and access the network as if they were directly connected to it. This is a common setup for many companies, which let their employees connect to the local business network remotely, so that they have access to internal resources that are only available on the local network. Linux administrators and power users may also be interested in setting up an VPN server at home, since they can then use their laptop or other portable device to connect to their home network while on the go.
SSH remote login syntax and examples
The SSH protocol in Linux is used to manage remote systems. Ordinarily, this would be another Linux system, but it could also be a firewall, router, or even a different operating system entirely. Using the SSH protocol to remotely log into another system will give you a command line terminal that you can fully access as if you were physically in front of the machine.
