Server

A headless server, as the name suggests, is a server that is operated without a monitor, keyboard, or mouse. These servers are typically managed remotely, making them an efficient and cost-effective choice for businesses, developers, and home users alike. Whether you’re setting up a web server, a file server, or a game server, a headless Linux server can be a powerful tool.

In this article, we will discuss the five different ways to open a port in Linux, which is a critical task for anyone who wants to run a service or application that requires network connectivity. We will explore each method in detail, along with practical examples and troubleshooting tips.

Nginx (pronounced as ‘engine-x’) is a popular web server software known for its high performance and reliability. It is open-source software used by many popular websites, including Netflix, GitHub, and WordPress. Nginx can serve as a web server, load balancer, reverse proxy, and HTTP cache, among other things.

If you are working with Linux and managing a network or a server, chances are you have heard about iptables. iptables is a powerful tool used to manage network traffic by filtering packets, and its use is essential to ensure the security of your system. However, iptables can be complex and challenging to master, especially when understanding chains and targets.

In today’s digital age, monitoring network traffic has become increasingly crucial for businesses and individuals. With the rise of cyber threats and attacks, being able to keep an eye on your network traffic can help you detect potential security breaches before they become a major problem. In this article, we’ll discuss using iptables to monitor and log network traffic for analysis.

In this article, we will discuss how to configure Iptables for IPv6 networks, including the basics of IPv6 addressing, the structure of IPv6 firewall rules, and some practical examples.

The Secure Shell (SSH) protocol allows for encrypted remote system management and file transfers across untrusted networks. SSH protects the connection between a server and a client by employing several encryption techniques, protecting the users’ instructions, authentication, and output from unwanted access and assaults. SSH is widely utilized in data centers and by nearly every organization operating on UNIX variations.

This article will discuss the usage of iptables in conjunction with Docker to enhance the security of containerized applications. We will explore the basic concepts of iptables, how to configure it to work with Docker, and best practices for securing Docker containers.

In this article, we will explore the benefits of using Iptables as a security tool for wireless networks. We will cover the basics of wireless networking techniques and demonstrate how iptables can help secure your wireless network from potential threats.

iptables are recognizable to most system administrators. It has been around for a long and is enabled by default in the Linux kernel. We may use iptables to ban a single IP address, several IP addresses, or whole networks. This may be useful if you receive repeated port scans or witness failed unauthorized access in your log files. IP blocking is a more effective security measure.
