Introduction As quantum computing advances, traditional cryptographic algorithms face potential vulnerabilities. Post-quantum cryptography (PQC) provides a proactive defense against future quantum attacks on TLS connections. The X25519+Kyber hybrid key exchange combines the proven security of classical elliptic curve cryptography with…
Introduction Running services on an IPv6-only VPS offers significant advantages including reduced costs, improved performance, and future-proofing your infrastructure. However, exposing these services to the broader internet—where many users still rely on IPv4—presents a unique challenge. This tutorial demonstrates how…
Modern web applications face increasingly sophisticated threats, from brute-force attacks to DDoS attempts. Traditional security tools often work in isolation, but CrowdSec revolutionizes threat detection by combining behavioral analysis with community intelligence. Unlike static solutions, CrowdSec creates a collaborative defense…
Traditional SSH authentication methods like passwords and even SSH keys are increasingly vulnerable to sophisticated attacks. Hardware security keys using FIDO2 protocols offer a revolutionary approach to secure server access, combining something you have (the physical key) with something you…
Data loss can be catastrophic for any server environment. Whether you’re running critical applications or storing important data on your VPS, having a reliable backup strategy is non-negotiable. Restic offers an elegant solution with its encrypted, deduplicated backups that work…
Introduction Network congestion control algorithms play a crucial role in optimizing internet performance, especially for VPS hosting and cloud infrastructure. BBR (Bottleneck Bandwidth and Round-trip propagation time) is Google’s revolutionary congestion control algorithm that has transformed how TCP connections handle…
Introduction As IPv4 address exhaustion continues to drive innovation in networking, many organizations are transitioning to IPv6-only infrastructure. However, the internet still heavily relies on IPv4 services, creating a challenge for IPv6-only deployments. This tutorial addresses the problem of enabling…
In today’s interconnected world, secure remote access to networks and the ability to route traffic through specific geographic locations has become essential for businesses and developers alike. Tailscale provides an elegant solution by creating a secure mesh VPN that simplifies…
Introduction Large Language Models (LLMs) have revolutionized how we interact with artificial intelligence, but accessing them often requires expensive cloud API calls or complex setups. Ollama solves this problem by providing a simple way to run LLMs locally, while Open…
