How to Configure VLAN Tagging with 802.1Q on RHEL 7 VLANs (Virtual Local Area Networks) allow a single physical network interface to participate in multiple logically isolated network segments simultaneously. The 802.1Q standard defines how Ethernet frames are tagged with a 12-bit VLAN ID, enabling switches and hosts to segregate traffic without requiring dedicated physical […]
Introduction This guide explains how to Secure Nginx with Let’s Encrypt on FreeBSD 14 on FreeBSD 14. 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 Deploying configure apache virtual hosts on freebsd 14 on a FreeBSD 14 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 Set Up Pacemaker and Corosync for High Availability on RHEL 7 High availability (HA) clustering prevents individual server failures from causing service outages by automatically detecting node failures and restarting workloads on surviving nodes. On RHEL 7, the standard HA stack is built from three components: Corosync, which provides reliable cluster messaging and […]
Introduction This guide explains how to Configure Nginx Virtual Hosts on FreeBSD 14 on FreeBSD 14. 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 14 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up install caddy web server on freebsd 14 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 […]
Introduction This guide explains how to Install Nginx on FreeBSD 14 on FreeBSD 14. 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. […]
How to Configure BGP Routing with BIRD on RHEL 7 Border Gateway Protocol (BGP) is the routing protocol that underpins the modern internet, enabling routers in different autonomous systems to exchange network reachability information. While large-scale BGP deployments typically run on dedicated hardware, Linux systems running RHEL 7 can participate in BGP routing using software […]
Introduction This guide explains how to Install Apache2 on FreeBSD 14 on FreeBSD 14. 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 How to Upgrade FreeBSD 13 to 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, […]
