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 […]
Introduction How to Set Up VLAN Tagging on FreeBSD 15 is a core administration task for any FreeBSD 15 server operator. FreeBSD 15 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 […]
Introduction This guide explains how to Harden Shared Memory 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.

Setting up configure database backups with mysqldump on FreeBSD 15 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. This […]
