How eBPF Intercepts Packets Before Kernel Routing
eBPF programs redirect packets at XDP or TC hooks before the kernel routing table is consulted, causing routing confusion when troubleshooting.

VLAN Tagging for Homelabs: 802.1Q Setup Guide
Segment your homelab network with VLAN tagging using 802.1Q. Learn switch configuration, trunk setup, and firewall rules to isolate IoT and untrusted devices.
Use eBPF in Home Lab Monitoring
If you want reliable home lab eBPF monitoring that mirrors production observability, you’re in the right place—we’ll show a practical approach that gives kernel-level visibility without changing every application. We use tools like Grafana Beyla and OpenTelemetry to surface network and app behavior directly from the linux kernel. That means quick wins: zero-code visibility for […]
