For almost a decade, I’ve been very slowly making progress on a multicast IPTV system. Recently I’ve made a significant leap forward in this project, and I wanted to write a little on the topic so I’ll have something to look at when I pick this up next. I was aspiring to have a useable system by the end of today, but for a couple of reasons, it wasn’t possible.
Now that lockdown is lifting a bit in Scotland, I’ve been going a bit further for exercise. One location I’ve been to a few times is Tyrebagger Woods. In theory, I can walk here from my house via Brimmond Hill although I’m not yet fit enough to do that in one go. Instead of following the main path, I took a detour along some route that looked like it wanted to be a path but it hadn’t been maintained for a while.

Ansible does have a module for doing pretty arbitrary things with web APIs though, so using that I’ve got the following playbook figured out to keep the reverse DNS entries in sync:
