Apache Virtual Hosts are a powerful feature that allows you to run multiple websites on a single server. With virtual hosts, you can configure Apache to serve different content based on the hostname or IP address of the incoming request. This makes it possible to host multiple websites on a single server, each with their own domain name, content, and settings. In this tutorial, we will show you how to create Apache virtual hosts on a RHEL/CentOS 8.0 server. We will cover the basic concepts of virtual hosts and walk you through the steps of creating virtual hosts using the ... Read More

PyGobject is a Python module that allows you to develop GUI applications in Python using the Gtk+ toolkit. With PyGobject, you can create rich, interactive applications that run on Linux, macOS, and Windows. In this blog post, we'll walk you through the process of creating two applications using PyGobject − a web browser and a desktop recorder. Creating a Web Browser To create a web browser using PyGobject, we'll need to use the Gtk+ webkit library, which provides a web browser engine that can be embedded into a Gtk+ application. Here are the steps to create a web browser − ... Read More

iSCSI (Internet Small Computer System Interface) is a storage networking technology that allows block-level data to be transported over an IP network. It is an alternative to traditional Fibre Channel SANs (Storage Area Networks) that use dedicated cabling to connect storage devices to servers. iSCSI can provide a cost-effective and flexible way to create a centralized storage infrastructure. In this tutorial, we will set up an iSCSI target on a RHEL/CentOS 7 server and connect to it using an iSCSI initiator on another RHEL/CentOS 7 server. We will configure CHAP (Challenge-Handshake Authentication Protocol) authentication to ensure secure communication between the ... Read More

Active Directory is a powerful tool for managing users, groups, and computers in a Windows environment. Samba is an open-source implementation of the SMB/CIFS networking protocol used by Windows for file and printer sharing. Samba4 provides a complete implementation of Active Directory and can be used to create an Active Directory infrastructure on Linux. In this article, we will go through the steps to set up an Active Directory infrastructure with Samba4 on Ubuntu. Step 1: Install Samba4 First, we need to install Samba4. Open a terminal and enter the following command to install Samba4 − sudo apt-get install samba ... Read More

As a software developer, you may need to distribute your software to different users. One of the common ways to distribute software in Ubuntu is to create a Debian package (.deb) and upload it to a package repository. A package repository is a collection of Debian packages hosted on a server, which can be used to install and update software on Ubuntu machines. In this article, we will show you how to create a .deb package repository using the Reprepro tool and host it on SourceForge.net. Prerequisites Ubuntu 18.04 or higher Root privileges Basic knowledge of Ubuntu package management ... Read More
