Automate LetsEncrypt certificate deployment in SecurityOnion

Prerequisites

A domain name
A DNS provider that works with Certbot. I'm using Cloudflare.
An API token for the DNS provider that is scoped to allow TXT record creation.
SecurityOnion 2.4 with sudo privileges and SSH access.

Turn on user certs in Security Onion (do this only once)

Administration -> Configuration
Options -> Show all configurable settings, including advanced settings

In this post, I'll start from scratch and build up to OpenClaw's architecture step by step, showing how you could have invented it yourself from first principles, using nothing but a messaging API, an LLM, and the desire to make AI actually useful outside the chat window.

End goal: understand how persistent AI assistants work, so you can build your own (or become an OpenClaw power user).

First, let's establish the problem

When you use ChatGPT or Claude in a browser, there are several limitations:

	> for (i in dtcols) {
	+ print(i)
	+ str(i)
	+ newname <- gsub("^X", "", i)
	+ print(newname)
	+ str(newname)
	+ }
	[1] "X08.04.17"
	chr "X08.04.17"
	[1] "08.04.17"

	Using the URLconf defined in az.urls, Django tried these URL patterns, in this order:

	^$
	^admin/
	^aztrack/

	.axis path,
	.axis line {

	}
	.x.axis path {

	COMPARE_FILES = True # should file sizes be compared if their names are the same?
