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:

What to do when Gmail marks all the mails from your server as spam

If you're self-hosting your services and having trouble getting your emails through Gmail and infuriated by Google's non-existent support, you're not the only one. I'd like to share my experiences trying to get it sorted out.

I'm the author of the post above. You can tell how arrogant Google employees are from all the previous posts he made in the past.

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

class ResponseStream(object):
    def __init__(self, request_iterator):
        self._bytes = BytesIO()
        self._iterator = request_iterator
