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.

Open ports allow a VPS to communicate with other systems and services. Each port represents a gateway for different applications, such as SSH for remote management, or HTTP and HTTPS for web servers. While open ports are necessary for application access, they also present an opportunity for attackers to compromise

For VPS users who operate websites, applications, and databases, file synchronization is extremely important. One missed backup can result in data loss, downtime, and recovery expenses. System administrators are constantly on the lookout for effective ways to keep data synced between servers, easily back-up data each day, and promote high

iperf3 is a command-line tool for assessing network performance. It allows you to measure bandwidth, latency, jitter, and packet loss between two endpoints. These measurements are useful for different scenarios like testing, checking the amount of available bandwidth, understanding the latency at peak hours, or planning a capacity for an

Operating a VPS means any and all network performance impacts the way your applications and websites behave. Just a split second of delay in transmitting data may result in slow page loads, service interruptions, and user dissatisfaction. A spike in traffic or undesirable bandwidth use puts the VPS in a

Kubernetes is the platform of choice for managing, scaling, and deploying containerized applications. The standard Kubernetes set-up (often referred to as "k8s") is complex and resource-intensive for smaller environments. Rancher Labs has developed k3s, a lightweight Kubernetes-compliant distribution. This guide will walk you through the steps to install

When managing a VPS, you often run the same commands in the same way every day. This could include updating packages, restarting web servers, or following system logs. These commands and processes are crucial. But the longer the command you have to type repeatedly, the longer it takes, and the

Disk I/O measures the speed of how quickly a server reads/writes to storage. On a Linux VPS, slow I/O will restrict applications, slow down response times to users, and ultimately create an unsatisfactory user experience. Dissecting, monitoring, and understanding these issue, will help to identify a bottleneck

ISO files contain an exact copy of a CD, DVD, or Blu-ray disc (and are compressed into a single file). In Linux, ISOs act as virtual discs, so they can be used like a disc without having to burn it onto physical media. ISOs are particularly useful for developers, system
