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:

Debugging apps (inspect)

Inspectability

Developer mode apps (those installed in /media/developer) are inspectable by default. Other apps (e.g., from the LG Content Store) are not inspectable by default, but you can add "inspectable": true to their appinfo.json to enable it. Debugging system apps (i.e., those in /usr/palm/applications) may require a special flag.

Ports

The developer mode app debugger listens on port 9998.

System service and system app debugging uses ports 5885 and 9999, respectively. However, debugging for these is not normally enabled.

typedef struct {
    uint8_t *bytes;
    size_t len;
} bytebuf;

OOP in Bash script

Wait, what?

Inspired by this awesome article.

Prelude about OOP

According to wikipedia, OOP is a programming paradigm or technique based on the concept of "objects". The object structure contain data and behaviour.

Data is the object's state, which should be isolated and must be private.
