Introduction Debian 13 Trixie is built around the ethos of stability and free software. Setting up configure postfix mail server on Trixie leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Trixie freeze. Follow each step carefully and the resulting configuration […]
Compression reduces the byte size of HTTP responses, lowering bandwidth consumption and improving page load times. Nginx ships with built-in Gzip support through ngx_http_gzip_module, but Gzip has largely been superseded by Brotli for text content — the Brotli algorithm typically achieves 15–25% better compression ratios at equivalent CPU cost. On RHEL 8, Gzip requires only […]
Introduction Deploying configure dhcp server with isc-dhcp-server on a Debian 13 Trixie 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. Prerequisites You will need a […]
Introduction Deploying configure dnsmasq on a Debian 13 Trixie 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. Prerequisites Ensure Debian 13 Trixie is fully updated […]
Rate limiting and connection throttling are essential defences against brute-force attacks, credential stuffing, and high-volume web scrapers. Nginx provides two built-in modules — ngx_http_limit_req_module for request-rate limiting and ngx_http_limit_conn_module for connection limiting — both compiled into the default binary. On RHEL 8 these capabilities are available immediately after installing Nginx from the AppStream module stream […]
Introduction Deploying configure dns with unbound on a Debian 13 Trixie 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. Prerequisites Ensure Debian 13 Trixie is […]
ModSecurity is not limited to Apache — it can also protect Nginx deployments through a dedicated dynamic module called ngx_http_modsecurity_module. The module embeds the ModSecurity v3 library directly into Nginx’s request processing pipeline, enabling the same OWASP Core Rule Set that Apache users rely on. On RHEL 8, Nginx is available from the AppStream module […]
Introduction How to Install BIND9 DNS Server on Debian 13 is a fundamental operation for any administrator maintaining a Debian 13 Trixie server. Debian 13 Trixie 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 12. […]
ModSecurity is a widely-deployed open-source Web Application Firewall (WAF) that integrates directly with Apache as a module. Combined with the OWASP Core Rule Set (CRS), it provides protection against the most common web attack categories including SQL injection, cross-site scripting, and remote code execution. On RHEL 8, both the mod_security Apache module and the mod_security_crs […]
