Multicast DNS Daemon

umdns

//This is early stage documentation, but at least attempts to cover some basic usage, and bring umdns usage out of the dark.//

mDNS, also known as Bonjour or zero-configuration networking (ZeroConf) or DNS Service Discovery (DNS-SD), enables automatic discovery of computers, devices, and services on IP networks. It is an internet standard documented in RFC6762.

The packages:pkgdata:umdns package provides a compact implementation of this standard, well integrated with the OpenWrt system environment. In particular, almost all interaction with the daemon is via docs:guide-developer:ubus.

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:

Concept 1

	#!/bin/bash

	mkdir aarch64
	mount --bind aarch64 aarch64

	pacstrap -c -K -M aarch64 base archlinuxarm-keyring dhcpcd \
	net-tools openssh vi which \
	firmware-raspberrypi linux-rpi \
	iw ldns less openresolv \
	wireless-regdb wireless_tools wpa_supplicant
