ciscocmd1
A small, deliberately simple network automation tool: take a list of commands from a text file and a list of devices from JSON, run them over Netmiko, and dump per-device output. The starting point referenced throughout the Python for Network Engineers and Ansible Deep Dive series — the "before" picture for what comes next as a script grows up.

web-traffic-generator
A polite round-robin GET request generator against ten public sites, used to produce a constant, predictable stream of background web traffic — handy for testing SDWAN application-aware routing, QoS shaping, and SLA measurement without waiting for real users to show up.
fgt-config-diff
A CLI and Flask web UI that parses FortiGate's config/edit/set/next/end syntax into a tree and produces a clean added/removed/modified diff between two configs — in text, JSON, or HTML — the way an admin actually reads a config, not the way a generic text-diff tool sees it.

pmtud-sweeper
A per-hop Path MTU Discovery sweeper. Binary-searches the largest DF-set IP packet each hop along a path will pass, and names the constraining router from its RFC 1191 Fragmentation-Needed replies. Four probe modes — ICMP echo, UDP, TCP-SYN, and full end-to-end TCP MSS handshake — with Rich-table or JSON output and CI-gate-friendly exit codes.
rst-forensics
A TCP RST origin classifier — server, mid-path firewall, or client — built on six independent scorers (TTL, IP-ID, window, options, sequence, timing) that vote with weights to produce a verdict with confidence and evidence. Pure Python core with optional scapy-backed pcap, passive, and active capture adapters.
