Description

This adds a simple model to use the web ui on PfSense machines to download the configuration. I use this in situations where I use oxidized to backup config from remote PfSense machines where I only have access to the web UI.

This is a RFC. I'm probably abusing a lot of code here, and I should write both documentation and some explaining about the model but I'm throwing this out there for some early feedback.

Oxidized offers an http input type which should support https. Is there any benefit to relying on mechanized directly instead of that input here?

[glance-]

This is way more "scraping" than what the http input can do. This needs Mechanize to handle session cookies, csrf-tokens and such.

Here is mechinize model: https://github.com/ytti/oxidized/blob/master/lib/oxidized/model/cambium.rb

I didn't see any sane way of using the existing @main_page / :login Mechanize functionally here , where I needed to set OpenSSL::SSL::VERIFY_NONE and a custom https-port. Also, I was a bit afraid of breaking the world if I tried to introduce those flags in http.

That was why I did it the way I did.

It's pretty easy to refactor this code if someone could point me in the right direction on how to get the http model working as needed.
