Even with SSH key-based authentication enabled, your server’s SSH port is still probed constantly by automated scanners. Fail2Ban monitors log files for repeated authentication failures and bans offending IP addresses by inserting temporary rules into the firewall. On RHEL 8, Fail2Ban integrates natively with firewalld, making it the right tool to complement the hardening steps […]
Introduction This guide explains how to Detect Rootkits with rkhunter on FreeBSD 13 on FreeBSD 13. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained […]

Introduction FreeBSD 13 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up set up the elk stack on freebsd 13 on FreeBSD 13 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any […]
Maven and Gradle are the two dominant build tools in the Java ecosystem, and knowing how to use both gives you flexibility across different project types and team conventions. Maven provides a well-defined project structure and a massive central repository of dependencies, while Gradle offers a Groovy or Kotlin DSL with faster incremental builds and […]
Introduction This guide explains how to Configure LVM on FreeBSD 12 on FreeBSD 12. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained privilege separation. […]
Introduction FreeBSD 13 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up install and use tmux on freebsd 13 on FreeBSD 13 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any Linux […]
Introduction This guide explains how to Configure Docker with a Non-Root User on Debian 9 on Debian 9 Stretch. Debian Stretch 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 9 install […]
