  Ansible Deep Dive Part 9 Lab: Zero to Production — a Three-Tier Web App From Bare Metal

  Part 9, the first lab: a role-based playbook standing up a load balancer, two app servers, and PostgreSQL from bare Ubuntu boxes — vault-protected credentials, templated HAProxy/env config, notify chains, and a rolling deploy with serial.

  Building a FortiManager Lab on Proxmox — Part 1: Lab Goals, Compute Sizing and Proxmox Host Preparation

  Part 1 of a five-part series on building a FortiManager lab on Proxmox. Covers lab goals, compute sizing for FMG and FGT VMs, host prerequisites, and a clean Proxmox 8.x baseline before the qcow2 build in Part 2.

  Building a FortiManager Lab on Proxmox — Part 2: Obtaining the Image, qcow2 Conversion and First Boot

  Part 2 of the FortiManager-on-Proxmox series. Walks through obtaining the KVM image from the Fortinet portal, validating the qcow2 files, building the VM shell with the right machine type and SCSI controller, importing both disks, and first-boot verification.

  Building a FortiManager Lab on Proxmox — Part 3: Proxmox Networking, Linux Bridges, VLAN-Aware Bridges and SDN for the Lab

  Part 3 of the FortiManager-on-Proxmox series. Designs the four-segment lab network, compares Linux bridges, VLAN-aware bridges and Proxmox SDN, walks through the /etc/network/interfaces shape, and explains why the lab bridges should never have an IP on the host.

  Building a FortiManager Lab on Proxmox — Part 4: A Lab Edge FortiGate VM in Front of FortiManager

  Part 4 of the FortiManager-on-Proxmox series. Builds a FortiGate-VM as the lab edge in front of FortiManager, with four NICs mapped to the lab bridges, a scoped policy set, FortiGuard pinhole, local-in policy hardening, and the deny-with-log rule that proves the boundary works.

  Building a FortiManager Lab on Proxmox — Part 5: Registering Managed FortiGates, ADOMs and Policy Package Installs

  Part 5 of the FortiManager-on-Proxmox series. Builds two managed FortiGate VMs, registers them via FGFM through the lab edge, splits them across two ADOMs, deploys a shared policy package with FMG, exercises revision history and rollback, and turns the lab into a snapshotted training platform.

  Linux Networking from the Ground Up: Network Namespaces, veth Pairs, and Building a Multi-Router Lab on One Host

  Build a real multi-router BGP and OSPF lab on a single Linux box using network namespaces, veth pairs, and FRRouting — no VMs, no containers, no GNS3. A practical walk-through of the primitives that GNS3, Docker, and Kubernetes are quietly using under the hood.

  Network Emulation with NETEM: Simulating Latency, Loss, Jitter, and Bandwidth Constraints for Realistic Lab Testing

  A practical guide to using Linux's NETEM qdisc to bend networks to your will — adding latency, loss, jitter, duplication, reordering, and bandwidth caps so you can test how applications and protocols actually behave when the network is anything other than perfect.
