Network bonding is a method used to combine multiple network interfaces into a single virtual interface, often to provide redundancy, improve network throughput, or load balance traffic across multiple interfaces. This technology is particularly useful in high-availability systems or environments that require higher network performance. In Linux, network bonding is implemented through the bonding kernel module, which allows multiple physical network interfaces to appear as a single logical interface. This guide explains how to enable and configure network bonding on a Linux system. The steps include loading the bonding module, creating a bonded interface, and configuring bonding options based on the network requirements. 1. Prerequisites Before configuring network bonding, you need to ensure that: The Linux system has multiple network …

What Is a Fork Bomb? A fork bomb is a type of denial-of-service (DoS) attack that rapidly creates new processes to exhaust a system’s resources. In Linux and UNIX systems, a fork bomb repeatedly calls the fork() system function, causing exponential process creation. As system resources get consumed, the machine becomes unresponsive or crashes. Fork bombs are commonly written in Bash, but they can also be created in Windows, Python, C, Java, and other programming languages. How Does a Fork Bomb Work? A fork bomb works by: This exponential growth quickly consumes: Eventually, the system freezes or crashes. Fork Bomb Example in Linux ⚠️ Warning: Do NOT execute this on a production system. Classic Linux fork bomb: Simplified version: Both …

TightVNC is a remote desktop software application and it can be used to connect to another computer and display its live remote desktop. Like other VNC systems, it consists of two parts: the “Server”, which shares the screen of the machine it’s running on, and the “Viewer”, which shows the remote screen received from the server. TightVNC Server is designed to run in two modes: Application mode & Service mode In application mode, the server, just like any other desktop software, can be running only during the current user session and quits on the log out. Each user has his/her personal settings and passwords. Service mode is configured independently of application mode; the settings and passwords of TightVNC Server as …
In Linux, everything running on the system is a process. Whether it’s a system service, background daemon, or user application, each runs in its own virtual address space. Since Linux is a multitasking operating system, multiple processes run simultaneously. Understanding how to monitor and manage these processes is a core skill for Linux administrators. This guide explains: What Is a Process in Linux? A process is a running instance of a program. When you execute a command, Linux: Every active task in Linux – including system services operates as a process. Types of Processes in Linux Linux systems run several categories of processes: 1. Interactive Processes Example: 2. Batch Processes 3. Daemon Processes Examples: Daemons typically have no associated terminal …
The RPM Package Manager (RPM) is a powerful command-line driven package management system capable of installing, uninstalling, verifying, querying, and updating computer software packages. Each software package consists of an archive of files along with information about the package like its version, a description, and the like. There is also a library API, permitting advanced developers to manage such transactions from programming languages such as C or Python. Yum is an automatic updater and package installer/remover for rpm systems. It automatically computes dependencies and figures out what things should occur to install packages. It makes it easier to maintain groups of machines without having to manually update each one using rpm. Yum has a plugin interface for adding simple features. …
