It is essential to secure your Ubuntu 24.04 Virtual Private Server (VPS) to prevent brute force attacks, port scans, botnet traffic, and other malicious activities. Iptables rate-limiting is one of the easiest and most effective security methods. It limits the number of connections or packets that an IP can

Anyone who manages a Linux virtual private server must be able to efficiently manage background services. Modern Linux distributions, including Ubuntu, Debian, CentOS, AlmaLinux, and Fedora, use systemd, a powerful init system that controls how services start, stop, and behave at boot time. Understanding systemd will improve your server management,

A slow VPS boot can adversely affect server performance, delay necessary applications, and cost you valuable uptime. If your server is too slow to boot, your users will experience delayed reactivity, and scheduled tasks may not be triggered. For businesses hosting websites, APIs, or production service, a slow boot means

Securing SSH for your Linux VPS server is the best way to protect it from brute force attacks and unauthorized access. Password-based logins can be extremely vulnerable. Automated bots will constantly try to guess passwords. Switching to SSH key-based authentication and adding two-factor authentication (2FA) creates a multi-layer, strong security

Hackers use port scanning as one of their most popular reconnaissance techniques to find vulnerable services and open ports on Linux VPSs. Attackers probe your system for potential entry points, regardless of whether your server runs SSH, Nginx, or MySQL. One of the best tools to protect your Linux VPS

If a VPS is being misused by consuming uncontrolled bandwidth, websites can slow down, applications can crash, and you may end up paying costly burst charges for exceeding your allotted bandwidth. If there are multiple services that run on the same domain07 server itself, such as websites, game servers, or

Shadowsocks, a lightweight, fast, and secure encrypted proxy, is designed to protect your online privacy and bypass censorship. Shadowsocks is a SOCKS5 proxy optimized for performance, which avoids network filtering and bypasses censorship. Setting up Shadowsocks on a Linux VPS is a straightforward process. This guide will walk you through

Logs accumulate quickly on a Linux VPS, and without proper management, you may end up running out of storage. Large log files can take up disk space, slow down your server and make troubleshooting difficult. If critical logs are lost in huge files, you may have to spend extra time

WebDAV (Web Distributed Authoring and Versioning), an extension of the HTTP protocol, allows you to create, delete, and modify files on your server. This is a great tool for web developers and teams who want a secure file management system that can be accessed via a browser or OS. WebDAV

Securing SSH is important for protecting your Linux VPS against brute-force attacks and bots that scan open ports. Port Knocking is one of the most effective yet underrated ways to improve server security. This technique hides your SSH port until a certain sequence of network "knocks' is sent.

Logs are essential in modern DevOps environments for debugging, monitoring, and maintaining the health of applications. Grafana Loki is a lightweight, cost-effective log management tool that can replace traditional log management software such as ELK. Loki is compatible with Grafana, Promtail, and other logging tools. This makes it the best

Having root access gives you unlimited control of a Linux VPS. Anyone with access to the root account can install software, edit configurations, and even remove critical files. While this is useful for administration, it can also backfire if left available. Hackers typically perform automated brute force attacks to guess

When managing a Linux VPS, secure and efficient file transfers are essential, especially for backups, migrations, and syncing large directories. Rsync is one of the safest and fastest ways to transfer files from server to server. It uses SSH encryption, while only synchronizing the changed portions of files.  This guide

Having a Virtual Private Server (VPS) requires vigilance with system logs. Logs track your every action, every error, and every event - these logs become integral in identifying performance issues, troubleshooting, repair, and security. Improper management of your logs can escalate the tiniest of issues into periods of downtime or

Modern cloud applications require reliable and efficient object storage. MinIO is a leading alternative to Amazon S3 that offers lightning-fast storage, which can be used on-premises and in the cloud. MinIO is a simple solution for enterprise-grade performance, whether you are hosting backups, managing containerized workloads, or serving media files.
