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 […]
How to Configure Network Bonding and Teaming on RHEL 7 Network link aggregation allows multiple physical network interfaces to be combined into a single logical interface, providing increased throughput and fault tolerance. RHEL 7 supports two distinct kernel-level mechanisms for achieving this: the older bonding driver, which has been part of the Linux kernel for […]
How to Set Up ZFS on RHEL 7 ZFS (Zettabyte File System) originated at Sun Microsystems and is widely regarded as the most feature-rich and reliable open-source file system available. It combines volume management, RAID, checksumming, copy-on-write snapshots, deduplication, and transparent compression into a single unified stack. The ZFS on Linux (ZoL) project brings these […]
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 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, […]

Introduction Deploying tune kernel parameters with sysctl 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 […]
