Traefik is a modern cloud-native reverse proxy and load balancer that can automatically discover services, obtain and renew TLS certificates via Let’s Encrypt, and expose a real-time dashboard — all without restarting when configuration changes. Unlike Nginx or HAProxy, Traefik reads its routing rules from provider backends such as Docker labels, Kubernetes annotations, or plain […]
Introduction Debian 10 Buster is built around the ethos of stability and free software. Setting up enable ocsp stapling on nginx on debian 10 on Buster leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Buster freeze. Follow each step carefully […]
The perf tool is a powerful Linux profiling framework built directly into the kernel, capable of sampling CPU performance counters, tracing system calls, and generating flame graphs that reveal exactly where an application spends its time. On RHEL 8, perf is packaged in the standard repositories and integrates with the kernel’s built-in performance monitoring units […]
Linux kernel parameters control how your system allocates resources, handles network connections, and manages memory. On RHEL 8, the sysctl utility provides a clean interface for reading and writing these parameters at runtime, while drop-in configuration files under /etc/sysctl.d/ make changes persistent across reboots. Properly tuned kernel parameters can significantly improve throughput, reduce latency, and […]

Introduction How to Configure Rate Limiting in Nginx on Debian 10 is a fundamental operation for any administrator maintaining a Debian 10 Buster server. Debian 10 Buster ships with the Linux 6.12 kernel, updated toolchains, and a fully refreshed package archive — meaning version numbers, configuration file paths, and some dependency chains differ from Debian […]
Introduction How to Enable Brotli Compression on Nginx on Debian 10 is a fundamental operation for any administrator maintaining a Debian 10 Buster server. Debian 10 Buster ships with the Linux 6.12 kernel, updated toolchains, and a fully refreshed package archive — meaning version numbers, configuration file paths, and some dependency chains differ from Debian […]
ZFS is a combined file system and logical volume manager renowned for its data integrity guarantees, transparent compression, built-in snapshotting, and copy-on-write architecture. While ZFS is not included in the RHEL 8 kernel, the OpenZFS project provides compatible DKMS packages that build the kernel module on demand. This tutorial covers adding the OpenZFS repository, installing […]
Introduction This guide explains how to Configure ModSecurity WAF with Apache2 on Debian 10 on Debian 10 Buster. Debian Buster uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian 10 install with […]
Introduction Deploying set up nginx as a reverse proxy on debian 10 on a Debian 10 Buster machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. […]
