A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

//! Experiments with async on embedded. This code runs on nRF52840-DK.
//!
//! On ARM Cortex-M cores interrupt requests can wake up the processor even when
//! interrupts are disabled by a critical section. The executor runs in a critical
//! section and puts the processor to sleep when no futures is ready.
//! A pending interrupt request wakes up the processor (without jumping to the ISR)
//! and the executor re-polls the futures for completion.
//!
//! Only supports a single task called `main_async` which can never be
//! interrupted (bus faults and other exceptions disregarded).

EKS on Arm

The xarm-install-graviton2.sh script allows you to install and use Amazon EKS on Arm (xARM) with a single command. In essence, it automates the steps described in the docs.

Make sure you have aws, eksctl, kubectl, and jq installed, this will be checked on start-up and the script will fail if these deps are not present. So far tested with bash on macOS.

$ chmod +x xarm-install-graviton2.sh
$ ./xarm-install-graviton2.sh
