network-namespaces

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.

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.

A Docker plugin for creating Linux-native virtual networks

Linux lab for asymmetric dual-WAN routing: requests leave on WAN1, replies return on WAN2, per destination. Policy routing, SNAT, and automated packet-capture verification.

Hands-on Linux networking labs on Ubuntu Server: namespaces, bridges, routing, DNS, DHCP, VLAN trunks, firewalls, packet capture and traffic shaping, validated with Python. Includes the design plan for Mini NaaS, a FastAPI network-provisioning prototype.

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

TCP Cubic vs BBR under random packet loss, measured with iperf3 and tc netem in Linux network namespaces

Common code

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

Enterprise network built with Linux network namespaces: VLAN segmentation, inter-VLAN routing, nftables firewalling, DNS, and troubleshooting runbooks.

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

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

Run commands with outbound network access sealed off: a lightweight Linux network-namespace sandbox with host allowlisting.

Measure what a custom OpenTelemetry Collector build (ocb) saves against contrib, and what resource detectors cost at startup on hosts that are not on those clouds. Real runs on a droplet, two network namespaces and a Raspberry Pi.

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)

University side project from a Network Management class, using Linux namespaces, BIRD and OSPF to measure routing failover and service continuity.
