How to Manage Disk Encryption with LUKS and cryptsetup on RHEL 7 Protecting sensitive data at rest is a fundamental security requirement for any enterprise system. Linux Unified Key Setup (LUKS) is the standard disk encryption specification on Linux, and cryptsetup is the command-line tool used to create and manage LUKS-encrypted volumes on RHEL 7. […]
Introduction How to Configure Static IP on FreeBSD 14 is a core administration task for any FreeBSD 14 server operator. FreeBSD 14 ships with the 15.0-RELEASE kernel, ZFS as the default root filesystem, Capsicum capability sandboxing improvements, and an updated ports tree. Unlike Linux distributions, FreeBSD uses rc(8) for service management, pf for packet filtering, […]
How to Configure IPv6 Networking on RHEL 7 IPv6 is the successor to IPv4, offering a vastly larger address space (128-bit addresses versus 32-bit), improved routing efficiency, and built-in support for auto-configuration and security features like IPsec. As IPv4 address exhaustion becomes a practical reality for many networks, enabling and configuring IPv6 on RHEL 7 […]
Introduction FreeBSD 14 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up install freebsd 14 on a server on FreeBSD 14 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 distribution. […]
Introduction Deploying automate freebsd 15 server provisioning with ansible on a FreeBSD 15 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 […]
How to Install and Configure MinIO Object Storage on RHEL 7 MinIO is a high-performance, S3-compatible object storage server written in Go. It can run as a single-node server or in distributed mode across multiple nodes, making it suitable for everything from development environments to production-grade data lakes. Because MinIO ships as a single static […]
Introduction This guide explains how to Configure pfsync Firewall State Synchronization on FreeBSD 15 on FreeBSD 15. 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 […]
Introduction This guide explains how to Set Up CARP High Availability on FreeBSD 15 on FreeBSD 15. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter.
