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.
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 an eBPF/XDP-based NAT Layer 4 load balancer works by building one from scratch. We implement simple connection tracking, deterministic hashing, and IP/MAC rewriting with a small, easy-to-follow example.
Learn how to build an eBPF/XDP firewall that filters packets by IP ranges using BPF_MAP_TYPE_LPM_TRIE and longest-prefix matching.
In this tutorial, you’ll learn the fundamentals of eBPF and XDP through example code that parses packets across different protocol layers, demonstrates how XDP actions work, and shows how these building blocks form the foundation for high-performance networking applications.
