Deep dives into DevOps and Server Side topics where theory blends with hands-on examples. You can try out commands from each tutorial in the attached remote playground, either from the browser or via SSH access from your local terminal — no extra setup required.
Tutorials from outstanding independent authors proudly hosted by iximiuz Labs.
This lab teaches you how to use eBPF to transparently intercept and redirect a client's outgoing traffic to an Envoy proxy without requiring any changes to the application code. You will build a system that recovers original connection metadata via socket-level hooks and uses SO_MARK to prevent infinite routing loops, replacing traditional, complex iptables rules with a high-performance eBPF alternative.
In this tutorial, you will learn how to build an Layer 2 DSR load balancer using eBPF/XDP, where backends send responses directly back to clients bypassing the load balancer.
Learn how to implement a basic per-client ICMPv6 packet rate limiter using eBPF/XDP. This tutorial shows how to track client activity with eBPF maps and enforce limits directly in the kernel—without any user-space interaction.
