Introduction Deploying install go on freebsd 12 on a FreeBSD 12 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard base + […]
Why IIS Security Hardening Matters A default IIS installation on Windows Server 2022 is functional but not fully hardened. Out of the box, IIS reveals version information in response headers, serves directory listings for unconfigured virtual directories, may support legacy TLS versions, and lacks the HTTP security headers that modern browsers rely on to prevent […]

This guide explains how to Configure Drone CI on Oracle Linux 9, with all the commands you need, the SELinux and firewalld considerations to keep in […]
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 […]
