Emulator for rapid prototyping of Software Defined Networks

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

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

A visual, deterministic network sandbox for testing nftables rules. It uses ephemeral Linux network namespaces (netns) and Scapy to validate firewall logic safely, providing real-time visual feedback via a Svelte/FastAPI interface.

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

A Docker plugin for creating Linux-native virtual networks

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

A Linux network namespace utility for isolated and proxied application environments.

Common code

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

LD_PRELOAD client library for xsocket (github.com/koro666/xsocket).

Simulating Layer-3 routing using Linux network namespaces and performing packet-level TCP & TLS handshakes for analysis using Wireshark.

xsocket backup repository with Make support - (github.com/koro666/xsocket)

VPN Cluster Orchestrator. NordVPN multi-instance manager via Network Namespaces.

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

Binds an IP-address to a subprocess through network namespaces - Linux only

Create two network namespaces and connect them by veth(virtual ethernet) cable. Here using Python & JavaScript(Node.js) & Shell Scripting.

Alternative xsocket-server written in pure Go - (github.com/koro666/xsocket)

Network namespaces, made navigable.

SOCKS5 to SOCKS port forwarder with UDP Associate, BIND, Tor and xsocket (github.com/koro666/xsocket) support. Good for forwarding the Tor SOCKS5 port to a network namespace or VRF.
