A modular multi-tunnel VPN orchestrator and DNS control plane with Tailscale, WireGuard, and Ad-blocking DoH support.

A precision timing control room for building, observing, measuring, and tuning multi-hop PTP clock cascades on one Linux host.

Linux network namespace-based transport performance benchmarking framework using tc, netem, iperf3 and optional eBPF instrumentation.

The project aims to demonstrate the basics of container creation and management on a Linux machine.

Common code

A minimal example reproducing a behavior I have with network namespaces and VLAN:s, written in C.

TCP/UDP port forwarder using xsocket (github.com/koro666/xsocket).
