Sessions at FOSS United meetups and a workshop at NITK, mostly making the case for open source alternatives to tools people are paying for or locked into. The detailed technical write-ups live under writing instead.
Why so many teams still pay for monitoring that locks them in, and what replaces it. Zabbix for full-stack monitoring and alerting, LibreNMS for SNMP discovery and network devices, ClickHouse for analytics over the volume the other two produce, and how the three combine in a hybrid setup.
FOSS Meetup 2025
A beginner session on what self-hosting actually replaces and what it costs. Which services are worth moving off, hardware from a Raspberry Pi to a second-hand server, the building blocks (Docker, Proxmox VE, reverse proxies, backups, dynamic DNS), and the mistakes people make before they hit them.
Aggregating several internet connections into one with Multipath TCP, so bandwidth and failover work even when the server at the far end knows nothing about it. How OMR does that, setting it up, and troubleshooting, with a live demo running on Raspberry Pi 4 boards.
A case-study session inside a five-day IIESoc workshop on IPv6 deployment. Stateful filtering under IPv6, where it departs from IPv4 habits, translating an existing rule set rather than starting over, and what to watch for while both stacks are live.
