Introduction Network security is a top priority for any organization that wants to protect its data and infrastructure from unauthorized access. Cyber threats come in many forms, such as viruses, malware, and hackers, and it's crucial to have a comprehensive security plan in place to mitigate these risks. One key component of an effective security strategy is the use of access control lists (ACLs). In particular, standard access lists are a commonly used tool for filtering traffic on a network. Definition of Standard Access List A standard access list is a type of ACL used ... Read More

Introduction Red Hat Enterprise Virtualization, or RHEV, is a virtualization platform developed by Red Hat Inc. that provides an open-source infrastructure for hosting virtualized workloads. It allows users to easily deploy virtual machines on top of a set of physical hosts, known as hypervisors. The RHEV environment consists of two main components: the management platform, which manages the entire infrastructure through a web-based interface called RHEV Manager; and the hypervisor hosts that run the virtual machines. Preparing for Virtual Machine Deployment System Requirements Before deploying virtual machines in a RHEV environment, it is important to ensure that your system meets ... Read More

Introduction SSH Port Forwarding is one of the most powerful and versatile features of Secure Shell (SSH). It enables users to securely access remote resources over an encrypted channel by forwarding TCP/IP traffic through a secure tunnel. SSH Port Forwarding, also known as SSH tunneling, is a technique that allows users to create a secure connection between their local computer and a remote server. It enables users to securely access remote resources, such as databases, web pages, or other network services that are not directly accessible from their local computer. Understanding SSH Port Forwarding How SSH ... Read More

From small businesses to large corporations, computer networks are crucial for organizations to function efficiently and effectively. In today's interconnected world, nearly every aspect of modern life depends on the proper functioning of computer networks. What is SSH? Secure Shell (SSH) is a network protocol that provides secure, encrypted communication between two computers. It is used to access remote devices over a network securely. SSH provides a way to establish an ... Read More

Introduction RedHat Enterprise Virtualization Hypervisor (RHEV-H) is a virtualization platform that provides an end-to-end, high-performance, and scalable solution to meet the needs of modern data centers. RHEV-H is based on the open-source Kernel-based Virtual Machine (KVM) hypervisor, which allows for hardware-based virtualization, enabling multiple operating systems to run on a single physical machine. With RHEV-H, organizations can create an infrastructure that is easier to manage and more cost-effective. Preparing for Deployment System requirements for RHEV-H deployment Before deploying RedHat Enterprise Virtualization Hypervisor (RHEV-H), it is important to ensure that the system meets the minimum hardware and software requirements. The following ... Read More

Introduction RabbitMQ is a messaging broker that allows different applications to communicate with each other by sending and receiving messages. It provides a reliable and scalable way to handle messaging between systems. On the other hand, Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. With Kubernetes, you can easily deploy and manage your applications in a cloud-native environment. Preparing for Deployment Setting up a Kubernetes cluster Before deploying RabbitMQ on Kubernetes, it is necessary to set up a Kubernetes cluster. A Kubernetes cluster is made up of one or more ...
